If you’ve been trying to conceive for any length of time (or at least thinking about it for any length of time) you have probably heard of LH strips (AKA OPKs, LH test, ovulation test, luteinizing hormone tests, ovulation predictor kits). LH strips are a pretty standard tool in the TTC communities and are often recommended to help improve odds of getting pregnant in any given cycle. But the way you use LH strips, whether correctly or incorrectly, could make or break your TTC efforts. This article will help you avoid making this common mistake.

What are LH strips?

LH strips are home urine tests that can be used to identify the surge of luteinizing hormone (LH). LH strips, when used correctly, predict ovulation to help couples who are trying to conceive by improving the precision of their efforts. Conception really only is possible during a six-ish day window of the menstrual cycle, corresponding to the five days leading up to and including ovulation, plus the day after. [Learn more about fertility, hormones, and the fertile window in my book, Go with Your Flow.] Contrary to most Sex Ed classes (or what is exemplified in the movie Mean Girls) a single sexual encounter is actually less likely to result in pregnancy then it is to cause it, statistically speaking. 

Knowing this, most cycle tracking apps offer a predicted fertile window to aid users in identifying the days of the month when they are likely to conceive from intercourse. Now, of course, these apps make their predictions based on averages (which ironically do not actually reflect the average woman) that assume a luteal phase length of 14 days, with ovulation occurring approximately mid-cycle.

To give you a few examples:

• For a woman with an average cycle length of 28 days, her app would predict ovulation on day 14, with a 14-day luteal phase thereafter
• A woman with a 35 day cycle would receive a prediction for ovulation on cycle day 21 (again with a 14-day luteal phase)
• A woman with a 24 day cycle would receive a prediction for ovulation on cycle day 10 (based on a 14-day assumed luteal phase)

While any of these scenarios could be true for a given woman, it is also true (and especially important to note) that countless other variations are also possible.

Why

Because not all luteal phases are 14 days in length.

Let’s go back to the “textbook” 28-day cycle for a moment: this woman may have:

• A 14-day luteal phase with ovulation on day 14
• But she just as easily may have a 12-day luteal phase with ovulation on day 16.
• Or even the somewhat atypical 15 (or more) day luteal phase with ovulation on day 13.
• She also could have a less-optimal but still potentially fertile 8-day luteal phase with ovulation on day 20. 

Even within just this 7 day variation, you can see easily that miscalculating the day of ovulation could mean completely missing the entire fertile window. Yikes.

So, instead of relying on the law of averages and missing the important detail of individual biology, scientists have come up with easy, at-home ways for tracking ovulation, based on the hormonal dance that takes place throughout a menstrual cycle. Ergo, LH strips or “ovulation predictor kits.”

How Do LH Strips Work?

In order to understand the lowly LH strip, we first need to understand it’s namesake hormone, LH–or luteinizing hormone.

In a nutshell, luteinizing hormone is a chemical signal sent by the brain to tell the ovary to release an egg.

The menstrual cycle is divided into two parts (which are, as we already learned, not necessarily halves) by ovulation, marking the transition point between the two.

The first part of the cycle, called the follicular phase is all about the development of an ovarian follicle (AKA egg) which bursts open during the event of ovulation. If a sperm is there, ready and waiting, when this occurs, fertilization and subsequent conception could theoretically occur. (Note: It goes without saying that many other factors are involved when determining whether or not pregnancy occurs, but those are beyond the scope of this article.) 

An Overview of Ovulation

During the follicular phase, the brain releases FSH, or follicle stimulating hormone, to facilitate maturation of the egg. As the egg matures, it produces increasing levels of estrogen, which the brain monitors. In addition to thickening and developing the uterine lining to prepare for a possible pregnancy (or period), this rising estrogen level serves as a communication signal to the brain to keep the nervous system in the loop about the status of the egg and it’s development. Once estrogen levels reach a high enough point, the brain then responds with its own signal (LH) to trigger ovulation.

After the follicle releases its egg, it then transforms into a progesterone-producing gland called the corpus luteum, which serves as the namesake for the second part of the cycle: the luteal phase. 

In reality, LH is produced at least a little bit every day of the cycle, even when menstruating. However, the key differentiating factor between “everyday LH” and the LH surge is the tremendous increase in amount of LH being released in any given moment. For younger women, the daily average LH level may be less than 1.0 mIU/mL, though for someone who is perimenopausal, it may fall into the tens-range. With regards to the brain-ovary line of communication, it’s not so much the actual numerical value of LH as much as it is the magnitude of change. To trigger ovulation typically LH levels must rise by a factor of 10, but for some people it is much more than this. It is not uncommon for LH levels to exceed 100 mIU/mL at the peak of the surge.

LH levels may also be high at a baseline in women with PMOS (formerly named PCOS) because of dysregulated estrogen signaling from polycystic ovaries. Both in the case of PCOS/PMOS and perimenopause, these slightly higher baseline LH levels may result in the rupture of more than one follicle at a time leading to a multiples pregnancy. This is why fraternal twins are statistically more common in women of older age and in women who have PCOS/PMOS. 

The Confusion About LH Strip Timing

Because LH starts to rise shortly before the release of the egg, and because conception is most likely if sperm are already ready and waiting in the fallopian tube at the time of ovulation, studies have identified that the most fertile days-–or the days of the cycle on which conception is most likely–-do not correspond to the day of ovulation itself, but rather to the day prior, and even the day before that. This allows sperm to make their way through the reproductive tract, undergo the capacitation process (which basically is just a fancy term for saying the sperm reaches its own peak maturity, which takes about 10 hours), and be ready to greet the egg when she make her arrival. 

To use an LH strip, a woman simply collects a urine sample, dips the test strip in the urine, and then waits a few minutes during which the LH present in her urine reacts with dye and adheres to a small line of antibody printed on the strip. Like a pregnancy test, LH strips also have a control line which is always dark in color. However, the key difference between a pregnancy test and an LH strip is the fact that LH is always present (whereas the pregnancy hormone hCG is not.) So, with an LH strip, a pale pink test line indicates a negative whereas a dark pink test line (which is as dark as, or darker than the control line) indicates a positive. 

But here’s the catch… LH surges for most women last multiple days. (Studies show an average of 4.8 duration.) Typically over this timeframe, the LH levels rise rapidly, peak, and then fall back down to baseline. While the actual length of the LH surge varies from woman to woman, the key factor here when predicting ovulation is to pay attention to the beginning of the LH surge rather than the peak. It’s the dramatic rising nature of LH that triggers ovulation, not the absolute maximum (as we have already discussed that the peak itself can vary in magnitude from woman to woman, as well as throughout a woman’s life, depending on the season of her fertility).

To flush this out a little bit more:

• One woman might have a 4-day LH surge with the peak occurring at the 48-hour mark
• Another woman might have a 1-day LH surge with the peak occurring at the 12 hour mark

Although the day of the peak itself varies in this scenario by over a day and a half, the important thing is that the beginning of the surge falls on the same day for both women. Because ovulation occurs roughly 12 to 36 hours after the start of the surge, both of these women would have ovulation happening on the same day. But for the first woman, her LH surge didn’t peak until after she actually ovulated. 

The real kicker is that this, statistically speaking, is the norm:

Medical researchers have found that for roughly 94% of ovulating women, LH peaked 1.2 days after ovulation already occurred. (Study link)

This means that if you are relying on the peak day, meaning the day that your LH strip is the darkest rather than the first day that you get a positive, and you are timing, your TTC efforts according to this, there is a very good chance that you will not be having sex until after ovulation has come and gone. Which means you aren’t going to get pregnant even if you have a perfectly healthy egg and a perfectly healthy sperm. (Chances of conception on the day after ovulation are 5% or less.)

Now this is an area of confusion that I often see among patients, in my real life conversations, and online. While many LH strips delineate the first positive day as being of highest importance in their instructions, the whole thing gets a little bit confusing because the test strips don’t provide numerical values; they simply use an analog, observation-based indicator. For women who are new to using LH strips, the color gradient can be kind of confusing. 

But let’s say you are among the women who know to count from the day of the first positive test. Well, because of the whole individual variation principle, and because of the variation among test sensitivity on LH strips from different manufacturers, you still might accidentally be missing the start of your LH surge. Here’s why…

How LH Strips Work 

I touched on this a little bit earlier, but to go into a bit more detail:

In an LH strip assay, urine flows across the strip and carries LH molecules toward antibodies attached to colored particles. The LH binds to these color-labeled antibodies, forming pink LH–antibody complexes. These complexes continue moving until they reach the test line, where another set of antibodies captures them. The accumulated colored particles produce the visible test line, with more LH generally producing a darker line. A separate control line confirms that the sample flowed correctly and the assay functioned properly.

Just like pregnancy test, which come indifferent sensitivity levels (i.e. 6.3 mIU/mL for the First Response Early Result compared to 25 mIU/mL for most standard tests and “internet cheapies”) LH strips can come in different sensitivity levels, generally ranging between 10 and 40 mIU/mL. An LH strip with a lower detection limit. (i.e. 10 mIU/mL) can pick up on lower level levels of LH hormone in the urine and will provide a brighter or darker test line. Meanwhile, an LH strip with a lower sensitivity. (i.e. 40 mIU/mL) will pick up LH in urine only when it has a higher level. Therefore, the same concentration of LH in the same urine sample would show up differently on these two tests: a darker line on the higher sensitivity LH strip (10 mIU/mL) and a lighter line on the lower sensitivity LH strip (40 mIU/mL).

If you are somebody who has a generally lower LH level and a comparatively lower peak, LH strips are going to show up lighter overall than someone who has a generally higher LH level. If you are using a high sensitivity test, this shouldn’t be a problem as it’s going to show test lines of the appropriate darkness and identify the beginning of your surge without issue. Like anyone else, your line will get darker as you reach the peak–but as we have already covered, it is the beginning of the surge that matters the most. This means that for the high sensitivity (10 mIU/mL) LH strip, the test line is equivalent in shade to the control line. But sometime thereafter, the test line would get darker than the control line (around your peak). However, if you were to use a lower sensitivity LH strip (i.e. 40 mIU/mL), your test line might not be dark enough at the start of your surge to indicate a positive test (as identified by a test line of equivalent darkness to the control line) even though, biologically speaking, the LH surge has started. 

In other words, you might not see a positive until you reach the peak of your LH surge which–if you are like the 94% of women in the world, is 1.2 days after ovulation rather than 12 to 36 hours before.

Understanding LH Strips in Real Life

Let’s take a look at this chart made using an Inito fertility monitor, which provides numerical data for all four fertility hormones (LH, estrogen, FSH and PdG, which represents progesterone).

As you can see on this chart, the purple line (LH) has risen dramatically from baseline levels. (This isn’t evident in the photo, but the day prior, the LH level was 0.08 mIU/mL). Having risen to 3.14 mIU/mL, it increased by several orders of magnitude, indicating the beginning of the LH surge. This indicates that ovulation will occur within 12-36 hours.

Now, let’s compare that same test to a standard, analog, over-the-counter LH strip:

The LH strip at the top of this photo was taken on the same day, with the same urine sample as the Inito reading. According to the definition of “positive” being the test line as dark as the control, this test would not be considered positive.

But we know that it is, because of the several days of preceding data identified with the Inito monitor.

Now let’s move on to the next day in this cycle:

On this next day, the Inito fertility monitor identified an LH level of 19.37 mIU/mL (corresponding to the peak of the surge) and the standard, over-the-counter LH strip turned positive (as evidenced by the bottom strip in the photo on the right, where you can also see the old, dried out strip from the day prior for comparison). The Inito identified the start of the LH surge on cycle day 12, whereas the OTC LH strip was negative. In reality, ovulation occurred sometime thereafter, and was likely complete by the time the LH surge reached its peak on day 13. The OTC LH strip did not identify a positive until cycle day 13, but as we know from Inito, ovulation had already likely occurred.

Here’s another example with Inito. In this cycle, the LH surge was identified on cycle day 16, with both the peak and the first positive taking place on the same day. In this case, the standard OTC test strip would be positive too.

Do you see the problem?

In short, standard, over-the-counter LH strips are great if you’re someone with a generally high LH level, but they may miss the start of the surge for women with lower levels (or more dilute urine). Missing the start of the surge by just one day could mean missing the day of ovulation altogether.

Of course, the obvious way around this is to make sure that you’re having intercourse (or, as it’s more commonly referred to on the online forums, “baby dancing”) daily throughout your fertile window. (If you don’t know when that is, I would suggest starting as soon as your period ends and continuing until you’re sure you’ve ovulated, whether via monitoring cervical mucus, basal body temperature, or with a device like Inito.)

Alternatively, you could check the sensitivity of your LH strips.

LH strips come with different sensitivity levels. When in doubt, use a high-sensitivity strip. Here are a few options:

• The Inito Fertility Monitor, which provides numerical data up to two tenths of a decimal (0.01 mIU/mL) for LH, plus the other 3 fertility hormones
• PreMom Quantitative Ovulation Predictor Kit and LH Strips which range from 0-65 mIU/mL
• Clearblue Advanced Digital Ovulation Test, which is sensitive to 40 mIU/mL
• Easy @ Home LH Strips, which observe 25-30 mIU/mL

The Bottom Line on LH Strips

If you’re using LH strips to time conception, don’t wait for the darkest test line to start trying. Pay attention to your month-to-month averages, and make sure you’re TTC well before your LH strips show a positive. View the LH positive as a signal for when you can stop trying (a few days after your positive) rather than a signal to start. Because a standard LH strip may miss the earliest part of your surge, consider testing more frequently as you approach your fertile window, and choose a more sensitive or quantitative test if your strips tend to turn positive late.

Most importantly, don’t put all your timing eggs in one hormonal basket: combine LH testing with cervical mucus, cycle patterns, or another method of confirming ovulation. The goal isn’t to perfectly predict the moment the egg is released, but to make sure sperm are already there waiting when it happens.

The post Are You Using LH Strips Wrong? appeared first on Dr. Alexandra MacKillop.

What is Eczema?

Eczema is more than just a rash. While rashes can pop up for many reasons, ranging from viruses to allergies to toxins, eczema is an immune system reaction that involves inflammation of the skin barrier. While eczema may be (and often is) triggered by allergic pathways including food and contact allergies, it also may be triggered by other factors that provoke an immune response. Getting sick, excess stress, lack of sleep, topical irritation, growth patterns (in kids), or anything else that shifts the immune response may also provoke eczema.

But one of the important missing pieces in the eczema conversation (and which is especially important when it comes to topical eczema cream or related products) is what happens after the initial reaction starts in the skin. The eczema pathway goes like this:

1. Trigger
2. Immune response
3. Skin inflammation
4. Microbiome shifts
5. Triggering of the inflammatory cascade

Points 4 and 5 are especially important. While eczema may be triggered by many different things, the next steps are all the same. First, the immune system starts mounting a reaction at the level of the skin, which creates significant inflammation. These inflammatory shifts change the chemical environment of the skin, which impacts the microbiome.

Remember that the human microbiome refers to all the microbes (viruses, bacteria, yeast) that live in and on the human body without (typically) causing problems. Most of these are beneficial organisms which play an important role in maintaining human health and helping the immune system learn how to tolerate the surrounding environment. However, some of them can become pro-inflammatory, especially certain strains of Staphylococcus and Streptococcus that live in the gut and on the skin. When the skin environment shifts after an eczema trigger, this favors the overgrowth of those staph and strep species, which grow exponentially at the level of the skin barrier. The immune system (understandably) is provoked to become even more reactive, and all of a sudden a cascade of inflammation, infection and immune reactivity is triggered.

Eczema Cream that Truly Heals

Most eczema cream available over the counter works by moisturizing and calming down the itching to prevent further damage to the skin barrier. While this activity of the cream is helpful and arguably important (it’s hard to heal skin that is constantly being scratched), it’s not addressing the reason for the itching. In many cases, eczema-prone skin is not necessarily dry or itchy of its own right. (Remember the role of the microbiome, here!)

Eczema cream that contains steroids utilizes another pathway, by suppressing the immune response to halt the inflammatory cascade. Unfortunately, however, this also impedes healing because the inflammatory response plays a role in stimulating the regeneration of inflamed skin. (Note: this is also the pathway involved in biologic medications for eczema, such as dupilumab/DUPIXENT.) From the standpoint of functional medicine, immunosuppression is not root-cause healing when it comes to eczema.

On the flip side, eczema cream that can effectively interrupt the inflammatory provocation cycle is how to calm down flares and promote healing when eczema gets out of control. This is where ozonated olive oil comes in to play.

Ozonated olive oil is a topical eczema cream prepared by infusing olive oil with ozone. Ozone is a naturally occurring gas found in the air we breathe and Earth’s atmosphere. It’s formed from three atoms of pure oxygen, essential for life. However, it can be highly disruptive to bacteria which consist of only a single cell. When exposed to ozone, bacteria quickly die, which means they stop provoking the immune response.

Ozonated olive oil therefore serves as a topical antibiotic without bringing the risks of other kinds of antibiotics. It powerfully kills bacteria and removes the trigger for the immune system’s role in an eczema flare. As an eczema cream, it addresses one of the most important mechanisms involved in the eczema response. However, ozonated olive oil also has an additional benefit as an eczema cream. Like other natural oils, it naturally soothes and regenerates skin, but it also directly calms down the inflammatory response, including the initial eczema-triggered responses. So, not only does ozonated olive oil interrupt the bacterial provocation of the immune system, it interrupts the original eczema-triggered inflammation, too. Topical application of ozonated oils quickly reduce itching, redness and inflammation associated with a variety of skin conditions including atopic dermatitis (eczema), one of the most common childhood ailments.

Is Ozonated Olive Oil an Effective Eczema Cream?

As a functional medicine doctor who recommends ozonated olive oil to my patients on a daily basis, the answer is yes! Even more, because it directly kills bacteria (instead of just preventing them from multiplying) it is one of the fastest acting options for eczema cream available.

Check out these results:

Gut Health and Eczema

Of course, eczema is triggered by something, so simply calming down inflammation when it’s triggered isn’t the whole story, either. In these cases, we still need to pay attention to the whole microbiome at large.

In patients with eczema, strong bodies of research show that imbalances in the gut microbiome and intestinal barrier (i.e. “leaky gut) strongly influence the onset of eczema. It also has a strong correlation to allergies, which are similarly connected to gut health. Research shows that patients with eczema have a few key imbalances that predispose them to this condition:

1. Reduced levels of Bifidobacteria, Bacteroides and Streptococcus salivarius
2. Increased pathogenic bacteria
3. Increased intestinal permeability and disruption of the intestinal barrier

This all leads to immune dysregulation (and emphasis on the Th2 immune response), altered production of short chain fatty acids as well as full-body inflammation.

Treatment for Eczema

Because there are so many types of bacteria that grow in and on humans, and because so many different types of eczema exist, and because each patient is different, there truly is no one-size-fits-all solution for eczema. However, there are a few universal steps that are recommended in the field of functional medicine that are a great place for getting started:

1. Identify allergies. As a functional medicine doctor, I recommend IgE panels for all the major allergens, as well as for any foods consumed daily (i.e. blueberries every day for breakfast). In resistant or complex cases, I may also recommend IgG/IgA food sensitivity testing. I ask my patients to abstain from all triggers for a minimum of 3 months before reintroducing, depending on skin status.
   • Over the counter options: Equal Dx Food Allergy Test, EverlyWell Food Sensitivity Test
2. Test the gut microbiome. In order to fix gut microbiome and intestinal permeability problems, you need to know what’s in there. As a functional medicine doctor, I don’t always test for “leaky gut” in all patients at the first appointment, as certain patterns of dysbiosis plus the fact of eczema itself is a sure sign of intestinal permeability.
   • Over the counter options: TinyHealth
3. Supplement strategically: Of course, an essential part of healing involves correcting deficiency of good bacteria and correcting the presence of overgrowth. However, spore-forming strains are an essential piece of healing the gut, and research strongly supports the use of Bifidobacterium and Lactobacillus. Healing the histamine response to calm IgE-mediated eczema pathways, and taking steps to rebuild the skin and gut barrier (with glutamine, histidine and proline) are also essential for healing the root cause.
   • Bifidobacteria
   • Lactobacillus
   • DAO
   • Spore-forming Probiotics
   • Histidine
4. Eczema cream: Ozonated olive oil is a quick way to calm down existing flares. In between, and to support the skin barrier, I recommend that my patients use vitamin C serum and postbiotic saccharomyces ferment medium, followed by a thick barrier cream at night.

The results sound sensational from a plan like this, but it’s a miracle I see every day in my practice. From eczema cream that actually works, to treating the root cause by digging deep into the microbiome, functional medicine has the answers for eczema, psoriasis and other skin conditions that are often mistreated in the standard medical community. That doesn’t have to be the case for you or your family anymore!

From a functional medicine perspective, postpartum cavities are not random. They are a predictable outcome of profound hormonal shifts, nutrient depletion, sleep disruption, and changes in oral and gut microbiomes that occur during pregnancy and the postpartum period. Understanding why postpartum cavities happen is the first step toward preventing and reversing them.

What Are Postpartum Cavities?

Postpartum cavities refer to tooth decay that develops during the months following childbirth. Some women notice sensitivity or pain shortly after delivery, while others discover postpartum cavities at their first dental visit after having a baby. In many cases, these cavities progress quickly and seem disproportionate to a woman’s oral hygiene habits.

This is often shocking, especially for women who brushed, flossed, and saw a dentist regularly before pregnancy. But postpartum cavities are usually less about hygiene and more about other aspects of biology.

Why Postpartum Cavities Are So Common

There is a perfect storm of factors that contribute to postpartum cavities, and they often overlap.

1. Hormonal Changes

Pregnancy and the postpartum period involve dramatic fluctuations in estrogen and progesterone. These hormones directly affect saliva production, blood flow to the gums, and the balance of bacteria in the mouth. Low estrogen postpartum can reduce saliva, and saliva is one of your primary defenses against cavities. Reduced saliva means acids linger longer on teeth, increasing the risk of postpartum cavities.

2. Mineral Depletion

Pregnancy places enormous demands on a woman’s mineral stores, particularly calcium, phosphorus, magnesium, and trace minerals. If these minerals are not adequately replenished postpartum, the body prioritizes survival and lactation over tooth remineralization. This creates a biological environment where postpartum cavities can form rapidly.

For several reasons, I usually recommend that my patients supplement with 1,000 mg of encapsulated calcium citrate beginning at 20 weeks gestation due to several studies indicating reduction in hypertension and pre-eclampsia risk in pregnant women. I recommend this practice continue for my patients who breastfeed their babies.

3. Changes in the Oral Microbiome

The oral microbiome shifts during pregnancy, often favoring more acid-producing bacteria. These changes don’t immediately reverse after delivery. When combined with lower saliva flow and mineral depletion, this microbial imbalance strongly contributes to postpartum cavities.

4. Increased Snacking and Nighttime Eating

Many new mothers eat more frequently (as well they should), often late at night (again, as well they should), to support breastfeeding and manage exhaustion. Unfortunately, frequent eating without immediate/adequate brushing increases acid exposure on teeth. This pattern is a significant driver of postpartum cavities, even when total sugar intake is not excessive.

Need an easy fix Pop a xylitol containing breath mint or chew a piece of xylitol-containing gum. Studies show that xylitol reduces the growth of cavity-forming oral bacteria. Xylitol consumption is considered safe during pregnancy (but check with your doctor) and studies even show that the children mothers who consume xylitol when pregnant themselves have lower risk of cavities.

Looking for an ultra-natural option? Underbrush Remineralizing Gum is a chewing gum made from natural tree sap with all natural ingredients and even nano-hydroxapatite which remineralizes teeth and stops decay.

5. Sleep Deprivation and Stress

Chronic stress and sleep deprivation elevate cortisol, impair immune function, and reduce the body’s ability to repair tissues. Teeth are living structures, and their ability to repair micro-damage is compromised in high-stress states. This is another underappreciated contributor to postpartum cavities.

I’ve said it before and I’ll say it again: sleep when your baby sleeps.

Why Traditional Dental Advice Falls Short

Most conventional explanations for postpartum cavities focus narrowly on brushing, flossing, and sugar intake. While these matter, they do not explain why so many women develop postpartum cavities despite good oral hygiene.

A functional medicine approach looks upstream. Postpartum cavities are a sign of systemic imbalance, not just local tooth decay. Addressing only the teeth without supporting the whole body often leads to recurring problems. Once again, a tooth problem is a gut problem, and we need to look inward to solve outward signs of toothe decay.

The Role of the Gut in Postpartum Cavities

It may surprise you to learn that postpartum cavities are closely tied to gut health. The gut microbiome influences mineral absorption, immune regulation, and inflammation throughout the body, including in the mouth.

Antibiotics during labor, C-sections, stress, and sleep deprivation all disrupt gut health postpartum. Poor mineral absorption and systemic inflammation increase susceptibility to postpartum cavities. Supporting gut healing is therefore a critical part of addressing postpartum cavities holistically.

Breastfeeding and Postpartum Cavities

Breastfeeding itself does not cause postpartum cavities, but it does increase nutritional demands. Producing breast milk requires significant amounts of calcium, magnesium, iodine, and fat-soluble vitamins. If intake does not meet demand, maternal stores are depleted, increasing the risk of postpartum cavities.

Based on his research in communities with little-to-no dental decay, Dr. Weston A Price (dentist) suggests a diet rich in whole foods, healthy fats, raw dairy and properly prepared (soaked, fresh-milled) grains. He also advocates for eating organ meats, bone broths, wild fish and fermented foods and avoiding processed foods. I will acknolwedge, postpartum is a time like no other to rely on prepared foods to support stress levels during the postpartum period. However, an ounce of prevention is worth a pound of cure. If you’re pregnant, check out this post about prepping nutritious meals for postpartum so that you are freed from so much reliance on food manufacturers to support your postpartum nutrition (seeing as they tend to be more concerned with their own profits than with your health, including your dental health.)

Nutrients That Protect Against Postpartum Cavities

One of the most powerful ways to prevent and heal postpartum cavities is by replenishing key nutrients.

• Calcium and phosphorus are foundational for tooth structure.
• Magnesium supports proper calcium utilization.
• Vitamin D regulates mineral absorption.
• Vitamin K2 directs calcium into teeth and bones rather than soft tissues.
• Vitamin A supports enamel integrity and immune defense.

Many women with postpartum cavities are deficient in one or more of these nutrients, even if they eat a generally healthy diet. All of these nutrients can be found in quality animal foods, like slow cooked meat on the bone. (And what postpartum mama doesn’t love a good crockpot meal?)

Blood Sugar Balance and Postpartum Cavities

Blood sugar instability is another overlooked contributor to postpartum cavities. Postpartum insulin resistance, sleep deprivation, and stress can all lead to blood sugar swings. Elevated blood sugar feeds acid-producing oral bacteria, increasing the likelihood of postpartum cavities.

Eating balanced meals with adequate protein, fat, and minerals helps stabilize blood sugar and reduce cavity risk.

What You Can Do If You Already Have Postpartum Cavities

If you’ve already been diagnosed with postpartum cavities, please know that this is not the end of the story. Dental treatment is sometimes necessary, but it should be paired with systemic support.

Addressing mineral repletion, gut health, hormone balance, and stress can slow or halt the progression of postpartum cavities and reduce future risk. Many women find that once these underlying issues are addressed, they stop developing new postpartum cavities altogether.

Practical Daily Habits to Support Oral Health Postpartum

Gentle but consistent oral care matters. Check out these tips:

• Use a soft toothbrush, particularly an electric one with a rotary head. We use the Oral B Pro 1000
• Avoid aggressive brushing (much easier with an electric brush), and consider remineralizing tooth powders or pastes. Rinsing with water after nighttime feeds or snacks can reduce acid exposure and help prevent postpartum cavities.

Avoid constant sipping on sweetened beverages, including juice and sweetened coffee drinks. Even “natural” sugars contribute to postpartum cavities when exposure is frequent.

Preventing Postpartum Cavities in Future Pregnancies

If you’ve experienced postpartum cavities once, you may be at higher risk in subsequent pregnancies. The good news is that prevention is possible.

Entering pregnancy with strong mineral reserves, supporting gut health, managing blood sugar, and prioritizing postpartum nourishment can dramatically reduce the risk of postpartum cavities the next time around.

Final Thoughts on Postpartum Cavities

If you are dealing with postpartum cavities, you are not alone, and you are not broken. This is a common and understandable outcome of the intense demands placed on the body during pregnancy and postpartum.

With the right support, education, and nourishment, it is absolutely possible to protect your teeth, restore balance, and move forward with confidence. Postpartum cavities are not just a dental issue—they are a whole-body message asking for care, rest, and replenishment.

And that message deserves to be heard.

The post Postpartum Cavities appeared first on Dr. Alexandra MacKillop.

What all these symptoms have in common is the indication that a person may be suffering from a form of chronic stress commonly known as “adrenal fatigue.” While it’s important to keep in mind that the cause behind these symptoms is not always adrenal fatigue (many other health concerns can present with these symptoms,) adrenal fatigue is a common topic that comes up in the Functional Medicine conversation.

Because the goal of Functional Medicine is to restore the body to optimal function, understanding adrenal fatigue first requires some context about how the body’s stress organs and stress responses ordinarily function under optimal circumstances.

Understanding Your Body’s Stress Response

The human nervous system always occupies one of two stress-related states—parasympathetic and sympathetic—commonly referred to as the “rest-and-digest” state or the “fight-or-flight” state, respectively.

During moments of relaxation, the parasympathetic nervous system is activated, and we enjoy all of our bodies’ healthy, restorative, balancing physiological functions. These include digestion, low blood pressure and heart rate, fertility, and a feeling of peace and calm.

During periods of stress, the sympathetic nervous system or “fight-or-flight” system becomes dominant, increasing heart rate and blood pressure, and slowing down bodily functions that are not essential in overcoming the stressor.

While it is both normal and expected for us to face periods of stress throughout our lives (maybe even on a daily basis, to some extent), staying in the sympathetic state for too long or facing stress triggers too frequently can lead to health problems that often bring debilitating symptoms.

What is Adrenal Fatigue?

Life stress comes in many different forms, though we often think of it in terms of psycho-emotional factors such as work demands or relational strains. However, the stress response in the body may also be triggered by illness, exertion (including intense exercise), nutritional inadequacies (especially under-eating), and more.

When a healthy person faces stress in his or her life, the body’s natural stress system (the sympathetic division of the nervous system) is well equipped to handle it. In a healthy stress response, the brain sends signals to a pair of glands located in a person’s abdomen, triggering the release of stress hormones. These hormones, including adrenaline, cortisol, DHEA and more, then enter the blood stream and travel throughout the body to create changes such as slowed digestion, elevated blood pressure, dilated pupils, an increased heart rate and breathing rate, increased mental focus, and more.

Once the stress trigger is overcome, everything is then free to relax: the adrenal glands stop producing the high level of stress hormones, and we resume our status quo.

The Stages of Adrenal Fatigue

When a person is exposed to too much stress—that is too long, or too frequently—the body’s stress response falls into dysfunction. This dysfunction follows a predictable pattern, culminating in a set of symptoms commonly known as adrenal fatigue:

• Stage 1: In the first stage of chronic stress, the body’s stress response becomes overactive, in a sense. This means that the release of stress hormones in response to a trigger increases more quickly than usual and remains elevated even long after the stress trigger has resolved.
• Stage 2: In the second stage of chronic stress, after the body has been stuck in a heightened stress state for a period of time, the body begins to lose track of what is and is not an appropriate reason to elicit a response. This results in a functionally backwards pattern in which the body triggers stress hormones to be released during times when no stress trigger exists; likewise, in situations in which a person might expect to feel triggered, the body fails to produce the appropriate stress response.
• Stage 3: In the third stage of chronic stress, the body altogether fails to produce a normal stress response. Even when real triggers are present, the nervous system fails to communicate with the adrenal glands properly, which subsequently fail to produce sufficient levels of stress hormones. The symptoms that accompany this stage are often referred to “burnout” or “adrenal fatigue,” but the medical term for all three stages of the chronic stress syndrome is hypothalamic-pituitary-adrenal axis dysfunction, or HPA axis dysfunction.

The timeline for progression through the three stages of HPA axis dysfunction—and chronic stress—looks different for different people, and depends on factors like age, biological sex, co-existing diagnoses, and personal history. This means that some people facing chronic stress may progress quickly to stage 3, possibly within just a few months, but others may not reach that point for years.

What Are the Symptoms of Adrenal Fatigue?

The specific symptoms may likewise differ from person to person, but most people experience some of the following:

• Body aches and pains
• Hair loss
• Headaches or migraines
• Skin discoloration
• Weight gain or weight loss
• Loss of libido and/or motivation
• Anxiety or depression
• Frequent respiratory infections
• Low blood pressure
• Dizziness
• Fatigue
• Mental confusion (i.e. “brain fog”)
• Insomnia

What Causes Adrenal Fatigue?nbsp;

Chronic exposure to psycho-emotional stress is the most commonly known cause of HPA axis dysfunction, though it is not the only one. Excessive exercise, inadequate nutrition habits (especially undereating), use of stimulants such as caffeine or nicotine, poor sleep habits, use of certain medications, and other lifestyle habits may also contribute to the development of adrenal fatigue. For most patients, it is a combination of triggers over time that ultimately predisposes them to develop symptoms.

However, the symptoms of adrenal fatigue are not unique to HPA axis dysfunction. This means that other conditions may be the true root cause. Other conditions that may contribute to the development of these symptoms include:

• Thyroid dysfunction
• An imbalance in gut bacteria
• Nutritional deficiencies
• Clinical depression, anxiety, or other mood disorders
• Adrenal diseases such as Addison’s Disease
• Neurologic disease
• Autoimmune disease
• …and more!

Because the of the diversity of potential causes underlying a person’s symptoms, it’s essential to not assume that adrenal fatigue is the correct label. Functional Medicine Doctors at Aligned Modern Health are committed to an evidence-based approach, which means that we run diagnostic tests with our patients so that we can make accurate diagnoses and put together a safe, effective, and minimally invasive treatment plan for our patients.

How Does Functional Medicine Test for Adrenal Fatigue?

Testing for adrenal fatigue involves a combination of blood test and specialty diagnostic testing through saliva. Depending on a patient’s symptoms and history, his or her Functional Medicine Doctor may order some additional or alternative tests in order to rule out the possibility of other conditions. The most common test used in suspected cases of HPA axis dysfunction is a saliva test which a patient completes by collecting saliva samples in small tubes at different periods throughout the day. These tubes are then sent to a laboratory for analysis of hormone levels, and the results are then assessed by the doctor in making a diagnosis and putting together a treatment plan.

How Does Functional Medicine Treat Adrenal Fatigue?

Because everybody is different and the underlying factors contributing to HPA axis dysfunction vary so widely from person to person, treatment plans likewise look different for each patient. However, every treatment plan will involve a variety of lifestyle interventions (nutrition, exercise, sleep hygiene, stress management) and nutraceuticals (clinical-grade herbs and supplements) to help support the body in healing. Some patients may also be referred for co-management with other providers, such as an acupuncturist or nutritionist.

If you are struggling with symptoms that you suspect may be related to chronic stress or anything else make an appointment with a functional medicine doctor for a thorough workup. Personalized diagnosis and treatment is the only way to get to the bottom of your symptoms and truly get the care you deserve.

Learning how to make a SCOBY hotel is part of developing a sustainable relationship with fermentation. When we understand how to make a SCOBY hotel, we are creating a stable environment where beneficial bacteria and yeast can remain alive, resilient, and ready to support future batches of kombucha.

What Is a SCOBY Hotel?

A SCOBY hotel is a glass jar filled with finished kombucha that houses one or more SCOBYs. The purpose of learning how to make a SCOBY hotel is to preserve extra SCOBYs in an acidic, protective environment so they do not dry out, become contaminated, or lose their strength over time.

If you brew kombucha regularly, understanding how to make a SCOBY hotel is essential for long-term success and peace of mind.

Why Learn How to Make a SCOBY Hotel?

There are several reasons I encourage anyone who brews kombucha to learn how to make a SCOBY hotel. One important reason is backup. Fermentation is a living process, and mistakes occasionally happen. Knowing how to make a SCOBY hotel ensures you always have a healthy culture available if a batch fails.

Another reason to learn how to make a SCOBY hotel is the strength of the starter liquid it produces. The liquid in a SCOBY hotel becomes increasingly acidic and microbially active, making it ideal for starting new batches safely. Learning how to make a SCOBY hotel also allows you to pause brewing without harming your cultures, which is especially helpful during travel or busy seasons of life.

What You Will Need

To begin how to make a SCOBY hotel, you will need a clean glass jar, ideally a half-gallon or one-gallon size. You will also need finished, plain kombucha and extra SCOBYs. When learning how to make a SCOBY hotel, it is important to avoid plastic containers or jars with spouts, the latter of which is harder to clean and may harbor bacteria.

A breathable cloth or paper towel and a rubber band are also necessary components for making a SCOBY hotel.

How to Make a SCOBY Hotel

The first step in how to make a SCOBY hotel is cleaning and sanitizing your jar. Wash it thoroughly with soap and hot water, rinse well, then sanitize with boiling water. Allow it to air dry completely. Clean equipment is essential.

Next, gently place your extra SCOBYs into the jar. It is completely normal for SCOBYs to stack, fold, float, or sink. All of these positions are acceptable and healthy.

Once the SCOBYs are in the jar, pour in enough finished, plain kombucha to fully submerge them. The acidity of the kombucha is critical to how to make a SCOBY hotel work, as it protects the cultures from mold and unwanted microbes.

Cover the jar with a breathable cloth secured by a rubber band. This allows airflow while preventing insects or debris from entering. Proper airflow is an important but often overlooked part of how to make a SCOBY hotel.

Place your SCOBY hotel in a room-temperature location out of direct sunlight. Refrigeration is not recommended when learning how to make a SCOBY hotel, as cold temperatures can weaken microbial activity over time.

How to Care for a SCOBY Hotel

One of the benefits of learning how to make a SCOBY hotel is how little maintenance it requires. Every four to eight weeks, check the liquid level and add more finished kombucha if needed to keep the SCOBYs fully submerged.

If the jar becomes crowded, remove older SCOBYs and compost them or share them with others who are learning how to make a SCOBY hotel themselves. Occasionally, if you are not brewing regularly, you may add a small amount of cooled, sweetened tea to keep the cultures fed. This optional step supports long-term success with how to make a SCOBY hotel.

Signs of a Healthy SCOBY Hotel

A healthy SCOBY hotel will have a clean, tangy, vinegar-like smell. The SCOBYs should appear wet, smooth, and cream-to-brown in color. Brown stringy yeast strands are normal and expected. Recognizing these signs is an important part of understanding how to make a SCOBY hotel with confidence.

If you ever see fuzzy blue, green, or black growth, that indicates mold. Mold is not normal, and the entire contents should be discarded if it appears. Fortunately, mold is rare when SCOBYs are fully submerged in acidic liquid and proper hygiene is followed.

Using SCOBYs From the Hotel

When you are ready to brew kombucha, remove one SCOBY and at least a half-cup of the liquid from the hotel to use as starter tea. The remaining SCOBYs can stay undisturbed.

Final Thoughts

Ultimately, how to make a SCOBY hotel is a small but powerful skill that supports long-term fermentation success. It protects your cultures, strengthens your kombucha, and reinforces the idea that caring for beneficial microbes is an ongoing practice.

Much like gut health itself, how to make a SCOBY hotel is about creating stable conditions, providing nourishment, and allowing time to do its work.

Are you wondering how to make kombucha from scratch Here’s everything you need to know.

As a functional medicine doctor, one of my favorite conversations with patients is about gut health and using naturally fermented foods to boost well-being in all systems of the body. The truth is, nearly all aspects of our health relate to our gut microbiome and the function of our guts, and fermented foods play a key role in keeping our gut healthy. My favorite foods to support gut health are homemade yogurt, fermented vegetables, and yes, kombucha, which I even give to my kids. But here’s the thing: there are tremendous benefits not just from drinking kombucha, but also in learning how to make kombucha from scratch. When you know how to make kombucha from scratch you get to control the ingredients, and flavor, but the actual fermentation culture morphs in ways that help reduce allergies and support gut health even more than store-bought varieties. This is exactly why I recommend that everyone I know learn how to make kombucha from scratch. Homemade is the ultimate form of food as medicine.

What is Kombucha?

Kombucha is a fermented tea made with brewed tea, sugar, and a SCOBY, an acronym which stands for symbiotic culture of bacteria and yeast. When you learn how to make kombucha from scratch, you see firsthand how this living culture transforms sweet tea into a tangy, effervescent, health-promoting drink. Kombucha tastes lightly sour, slightly sweet, and naturally fizzy. Many people drink it as an alternative to soda, for digestive support, or for a gentle energy boost without the crash that comes from coffee. It’s grown in popularity over the past decade or so, and because of this, it can be quite pricey (up to $4 or $5 per bottle!) It’s much less expensive to make it at home, and this is another reason that so many people want to lear to make kombucha from scratch.

Health Benefits When You Make Kombucha from Scratch

From a functional medicine perspective, the health benefits of kombucha include improved digestion, support for gut microbial diversity, organic acids like butyrate that help balance harmful bacteria and repair the gut lining, and antioxidants from tea polyphenols. When I’m asked why someone would want to make kombucha from scratch, I explain that homemade kombucha often contains more active enzymes and beneficial compounds than store-bought versions.

There are additional advantages when you learn how to make kombucha from scratch at home. First, the SCOBY becomes stronger and healthier SCOBY over time, which improves fermentation quality. You can’t buy time at the grocery store, which is a godo reason to learn to make kombucha from scratch at home.

The most important reason to make kombucha from scratch, though, is because the culture changes and adapts based on the environment. In grocery store kombucha, the food manufacturers use the same bacteria and the same fermentation conditions exactly the same way for every, single batch. This is a good thing because then their products taste exactly the same, every time. I don’t know about you, but if there’s a product I love, I am not very happy when it tastes different without warning. However, the limitation of a standardized bacterial culture is that it is only adapted to the temperature-controlled fermentation chamber; it doesn’t pick up any diversity of strains based on the environment. When you make kombucha from scratch, though, the SCOBY and the fermentation medium pick up strains of bacteria and yeast from your house, and this educates your own immune system how to learn to “tolerate” non-self material. Allergies and intolerances are the epitome of immune system intolerance, meaning that our immune systems wrongly react against normal, healthy things in our environments. Consuming home-fermented foods allows our guts to become exposed to these allergens in controlled, healthy ways, supporting overall immune health and reducing the propensity to develop and react to allergens. With allergies on the rise, the fact that I know how make kombucha from scratch, is, as I see it, one of the best skills for helping to support my children’s health.

How to Make Kombucha from Scratch

To make kombucha from scratch, you will need the following ingredients and equipment:

• Filtered water
• Black (or black and green) tea (tea bags or loose leaf)
• Organic cotton strainer, if using loose leaf tea
• Sugar (I recommend organic cane sugar)
• A large, 1-gallon glass jar for fermentation (do not use the kind with a spout, as this is hard to clean and can harbot bacteria)
• Cheese cloth or paper towels
• A large rubber band
• Kitchen funnel
• Glass bottles, with seals
• A SCOBY (synbiotic colony of bacteria and yeast) with cultured kombucha
• A cool, dark space for fermentation

Choosing the Tea

The basic process for how to make kombucha from scratch starts with tea selection. Black tea works best because it provides caffeine and nitrogen (tannins) that the SCOBY needs. If you do choose to use green tea, it’s recommended to use half green tea and half black tea to provide a source of the tannins. Without them, the SCOBY may die. If you’d like to use exclusively green tea, it is recommended to use a “Jun SCOBY.”

When using tea, it is important to only use pure tea, not flavored teas or aromatic black teas like Earl Grey/Lady Grey/Bergamot tea or Jasmine Green Tea (which are flavored with citrus oils that can suffocate the SCOBY; see below).

Herbal teas should be avoided, as they lack the nutrients required for proper fermentation and often contain essential oils which can suffocate the culture. (Oils rise on top of the liquid and block oxygen from getting to the SCOBY, suffocating it.) If you’d like to flavor your kombucha, use a second ferment with fruit juice (see below).

A note about tea bags: Tea bags notoriously leach plastic and endocrine-disrupting chemicals into the tea. When learning how to make kombucha from scratch, you have the power to take steps to avoid this sort of contamination. I recommend using loose-leaf tea, or cutting open the tea bags and pouring into an organic cotton straining bag instead. Alternatively, you could brew the loose leaf tea and then pour through an unbleached coffee filter.

Sugar

Sugar is necessary to make kombucha from scratch because it feeds the yeast and bacteria. Using honey, maple syrup, or artificial sweeteners disrupts fermentation and may cause mold or kill the SCOBY, which is why traditional sugar is essential when starting to make kombucha from scratch. I recommend using organic, unbleached cane sugar. If you’re worried about sugar intake, don’t be! Properly prepared kombucha means that the bacteria consume most of the sugar through the fermentation process, so although the finished product tastes slightly sweet, it has much less sugar than the ingredient list calls for.

Flavor Variations

The recipe on this page explains how to make kombucha from scratch, but it is for making plain kombucha. Plain kombucha can be flavored in 3 ways. The first and most common is with a second cycle of fermentation. To do this, bottle the finished, plain kombucha with a small amount of fruit juice and return it to the fermentation location for another few days (we like to do about 7 days with a ratio of 4 parts kombucha to 1 part juice) before moving to the refrigerator. Avoid using citrus juices as these may contain citrus oils that may suffocate the culture. Do not use this flavored kombucha to bulk ferment with a SCOBY, as it can hurt the SCOBY and increase risk of mold growth.

The second way to flavor kombucha is by serving with a fresh slice of lemon or some frozen fruit as “ice cubes” to impart flavor after the kombucha is finished.

The third way to add flavor to kombucha from scratch is by mixing it into a “mocktail” with a splash of fruit juice, some seltzer, and maybe a glass with a salted rim. Get creative or look up some tried-and-true favorites online.

A note about kombucha flavor: the relative acidity and sweetness of the kombucha can also be adjusted based on fermentation time. The longer the kombucha ferments in the initial phase, the more acidic (like vinegar) and less sweet it will become. If you leave the kombucha too long, it may turn into vinegar and kill the SCOBY. The first round of fermentation typically ranges from 7-14 days. My family tends to prefer a shorter time, closer to 8 or 9 days. If it tastes too acidic (or if I ferment it longer) I typically dilute it with water before serving. When performing a second ferment with fruit juice, I usually opt for an additional 5-7 days, but you can go up to 10.

How to Make Kombucha from Scratch: Troubleshooting

Sometimes, the kombucha SCOBY can become contaminated and grow mold. It is not safe to drink kombucha with a moldy SCOBY. Mold appears fuzzy and blue, green, or black. If you see mold, discard the batch. Stringy brown strands are normal yeast and are part of healthy fermentation.

The SCOBY should always appear smooth and “wet,” but will likely be multicolored with different areas of brown, beige and tan. This is all normal. Anything that looks “dry” or furry is not. When it doubt, throw it out and start again.

That being said, contamination is rare when you use properly cleaned and sanitized equipment. Basic kitchen hygiene practices are an essential piece of learning how to make kombucha from scratch! That being said, you should never bleach your equipment, as residual bleach may kill the culture. Instead, scrub with a soapy sponge, rinse well with hot water, and sanitize with boiling water. Then, air dry completely before using the equipment.

Storing Kombucha

Prepared kombucha really can last indefinitely in the refrigerator, but develops off flavors if left too long. We typically consume within 3 months.

How to Get a SCOBY

The best way to get a SCOBY to start brewing kombucha from scratch is by knowing a friend who can share a SCOBY with you. However, if you don’t know of a home-brewing friend, you can make one yourself using prepared plain kombucha. See this blog post for details: How to Make a SCOBY (from scratch!)

The post How to Make Kombucha from Scratch appeared first on Dr. Alexandra MacKillop.

If you already know how to make kombucha from scratch but don’t have a SCOBY to get started, the next natural question is how to make a SCOBY at home. The good news Learning how to make a SCOBY is surprisingly simple and easy, requires very few ingredients, and is an empowering step toward truly DIY fermentation.

As a functional medicine doctor, I love teaching patients how to make a SCOBY because it reinforces an important concept: our bodies thrive when we work with microbes, not against them. Making your own SCOBY at home allows beneficial bacteria and yeast to adapt to your environment, supporting gut and immune health in ways store-bought cultures simply can’t.

What Is a SCOBY?

A SCOBY is a Symbiotic Culture of Bacteria and Yeast. It’s the living fermentation starter that transforms sweet tea into kombucha. When making a SCOBY, you’ll see this culture form gradually as bacteria and yeast from prepared kombucha colonize fresh tea and sugar, creating a new, rubbery disc at the surface of the liquid.

This natural process of fermentation is what has worked for thousands of years. The bonus is that when you make it today, you are combining ancestral history with your own modern environment for immune support and gut health that transcend the bounds of time.

Why Learn How to Make a SCOBY from Scratch?

Many people ask why they should bother learning how to make a SCOBY instead of buying one. From a functional medicine perspective, there are several important reasons:

• Homemade SCOBYs adapt to your home environment, so the microbial community becomes more diverse over time
• You avoid preservatives or processing used in commercial cultures
• You gain a deeper understanding of fermentation and food as medicine
• If you don’t know someone who has a SCOBY to share, you might be limited to buying one online. That can carry risks. Making a SCOBY from scratch is also a safety measure!

What You’ll Need to Make a SCOBY

You will need to following materials to make a SCOBY:

• 1 quart (4 cups) filtered water, boiling
• 2 black tea bags or 2 teaspoons loose-leaf black tea
• ¼ cup organic cane sugar
• 2 cups plain, unflavored, raw kombucha (store-bought or homemade)
• 1 wide-mouth glass jar (ideally 1-gallon size, as you’ll be using this to brew kombucha in the future)
• Cheese cloth or paper towel
• Rubber band

The quality of your kombucha matters here. For best results when making a SCOBY, choose kombucha that is raw, unpasteurized, and free from added juices or flavors.

Step-by-Step: How to Make a SCOBY

1. Brew the Sweet Tea

Bring the water to a boil, steep the tea for 2–5 minutes, then remove the tea (bags). Stir in the sugar while the tea is hot, allowing it to dissolve completely. Let the tea cool to room temperature.

This is critical, as hot liquid can damage beneficial microbes.

2. Add the Kombucha

Once cooled, pour the sweet tea into your glass jar and add the prepared plain kombucha. This inoculates the tea with the bacteria and yeast needed to begin forming a SCOBY.

3. Cover and Ferment

Cover the jar with a breathable cloth secured by a rubber band. Place it in a warm, dark location away from direct sunlight for 10-14 days.

Now the real magic begins.

What to Expect During SCOBY Formation

Within 3–7 days, you may notice a thin, cloudy film forming on the surface. This is the early stage of SCOBY development. Over the next 1-2 weeks, that film will thicken into a solid, rubbery disc. Cooler temperatures may slow the process, while warmer environments speed it up.

A finished SCOBY is typically ¼–½ inch thick and smooth in appearance. Brown strands or sediment beneath it are normal and healthy. As you use the SCOBY to brew kombucha, additional layers will form, right on top of each other. You can peel these layers off and share them, along with 1/2 cup of brewing liquid, with friends and family so that they can brew their own kombucha.

Troubleshooting

If you see fuzzy blue, green, or black growth, that is mold—not good. Discard the entire batch and start again. Pay attention and make sure that you use clean equipment sterilized with hot water. Do not use bleach, and make sure that any soap is thoroughly washed off before sterilizing.

Healthy SCOBYs look wet, glossy, and cream-colored to tan. When in doubt, trust your instincts.

Using Your Homemade SCOBY

Once you’ve successfully made your SCOBY, you can use it to brew your first full batch of kombucha. The liquid underneath your SCOBY is now strong starter tea and should be saved for future batches.

Over time, your SCOBY will grow and form layers. These “baby” SCOBYs can be shared, stored, or used to continue brewing.

Final Thoughts

Learning how to make a SCOBY is one of the most empowering skills you can develop in your fermentation journey. It connects you to traditional food preparation, supports gut and immune health, and reinforces the idea that healing often starts in the kitchen.

When we invite beneficial microbes into our homes through intentional fermentation, we’re teaching our immune systems tolerance, resilience, and balance. And that, in my view, is true food as medicine.

Who doesn’t love a good oatmeal banana chocolate chip muffin We often think of muffins as a wholesome breakfast or snack, but from a nutritional standpoint, most muffin recipes are essentially cupcakes without frosting. They are typically made with refined flour, added sugars, and minimal fiber—ingredients that can lead to rapid blood sugar spikes and crashes. When it comes to carbohydrates, less is more, though that doesn’t mean we can’t or shouldn’t enjoy foods we love. Instead, we can look for ways to adapt classic recipes to be healthier and more conservative in our use of sugar, which does not occur as abundantly in nature as it does in ultra-processed foods.

These oatmeal banana chocolate chip muffins are designed to be a more nourishing alternative. They prioritize fiber, minimize added sugar, and support metabolic and gut health—without sacrificing flavor or texture.

Why Most Muffins Miss the Mark Nutritionally

Traditional muffins often contain as much sugar as dessert. Even when they’re labeled “healthy,” they may rely on fruit juice concentrates, white flour, or excessive sweeteners that behave the same way in the body as sugar. The result is a quick rise in blood glucose followed by an inevitable crash, which can lead to fatigue, irritability, and increased cravings later in the day. Many gluten-free recipes also rely on 1:1 flour blends which lack the fiber and micronutrients found in whole grains, so even without the gluten, they aren’t necessarily much better.

This recipe uses whole grain, gluten-free oats, with robust sources of fiber, which keeps you full, regulates digestion, and prevents blood sugar spikes.

The Gut Health Benefits of Oatmeal Banana Chocolate Chip Muffins

These oatmeal banana chocolate chip muffins aren’t just a source of dietary fiber—they’re a source of beta glucans, which is a unique type of soluble fiber with well-documented health benefits. Beta glucans act as prebiotics, feeding beneficial gut bacteria and supporting a healthy microbiome. A well-balanced gut microbiome is linked to improved digestion, reduced inflammation, better immune function, and even more stable blood sugar levels. So, not only do these oatmeal banana chocolate chip muffins taste great to you, they feed your beneficial microbes, too!

From a functional medicine perspective, gut health and metabolic health are deeply interconnected. By mindfully incorporating oats into baked goods like muffins, we can support both systems simultaneously.

Bananas and Chocolate

Bananas provide natural sweetness, which allows us to significantly reduce or eliminate added sugars. When paired with fiber and healthy fats, their impact on blood sugar is far gentler than refined sweeteners alone. Using ripe bananas also enhances flavor and moisture, reducing the need for excess oil or sugar.

Chocolate chips are a classic companion to banans in these oatmeal banana chocolate chip muffins included for enjoyment, but used with intention. I like to use stevia-sweetened chocolate chips, which are naturally sugar-free, such as Lily’s oatmeal banana chocolate chip muffins. Chocolate can easily drive up the sugar count on an already carbohydrate-rich food, so I like to minimize this when I can by using alternative brands.

Stable blood sugar is not just a concern for people with diabetes. Everyone benefits from minimizing glucose fluctuations. Consistent spikes can drive inflammation, hormone imbalance, and energy instability over time. A breakfast or snack that combines fiber, protein, and healthy fats—like these oatmeal banana chocolate chip muffins—helps set the tone for the day.

Instead of snacking on sugar, you’re nourishing your body with ingredients that promote steady energy and digestive health.

A Muffin You Can Feel Good About

These muffins are proof that baked goods don’t have to be nutritionally empty. By swapping refined ingredients for whole, functional foods, we can create recipes that support blood sugar balance, gut health, and long-term wellness.

Because when we rethink our everyday foods, even something as simple as a muffin can become an opportunity for better health.

Anohter tip Consider blending 2 cups of spinach in with these oatmeal banana chocolate chip muffins. I promise, you won’t taste it at all and you’ll have that much more of a nutritional punch when you snack.

Early awareness of signs of pregnancy before missed period depends on pattern recognition rather than a single symptom. It’s common to have one of these signs or symptoms at nearly any time throughout the month. However, when many occur at once during your two-week-wait, you should pay attention—though of course you will still need to take a test to confirm.

Symptoms-Related Signs of Pregnancy Before Missed Periods

1. Tender Breasts

Breast tenderness ranks among the most reported signs of pregnancy before missed periods. Rising progesterone and estrogen increase blood flow and glandular activity within breast tissue, leading to fullness, sensitivity, or a heavy sensation. Observation requires no tools, only awareness of changes that differ from a typical premenstrual pattern. In other words, if you don’t normally experience breast tenderness before your period but this month you do, pay attention. It could be pregnancy. Other explanations include luteal phase progesterone surges, high prolactin from stress, caffeine excess, or a new exercise routine.

• Research Brief: 76% of pregnant women experience breast pain or tenderness during the first trimester, whereas research on US women noted that only 69% experience it as a PMS symptom.

2. Mood Changes (Atypical for You)

Mood shifts often appear early among signs of pregnancy before missed period. Neurotransmitter signaling responds quickly to progesterone metabolites, influencing emotional processing, irritability, tearfulness or just a greater overall emotional sensitivity. One good way to identify if changes in mood could be a sign of pregnancy is by tracking mood daily through journaling. Mood changes are common during pregnancy, but if you notice a change in the intensity or type of moods you experience, it could be a sign to pay attention to. Other causes of mood variation include PMS, sleep disruption, blood sugar instability, or psychosocial stress. For most of us, our moods change day-to-day. However, a pattern that feels distinctly different from prior cycles carries more weight.

• Research Brief: A large international study showed that up to 64% of women experience mood changes in the premenstrual period. In contrast, a global study revealed that the prevalence of depression, anxiety and stress in the first trimester averages about 27%. Depending on your individual situation, a lack of mood swings in the premenstrual window when you usually have them may be more of a flag for possible pregnancy.

3. Vivid Dreams

Intensified or unusually vivid dreams frequently accompany signs of pregnancy before missed period. High levels of progesterone alter sleep architecture, increasing REM density and dream recall. Noticing this change involves subjective reporting rather than measurement. Relative accuracy stays low to moderate. Similar dream changes follow melatonin disruption, magnesium deficiency (or supplementation), late-night eating, or anxiety.

• Research Brief: The research here is somewhat limited, so we need to draw some extended lines. But here’s what we know: across both genders, about 54% of people report frequently recalling their dreams. On the other hand, up to 91% of pregnant women report dream recall. This may be due to hormonal reasons, a lack of REM sleep, interrupted sleep, among others.

4. Cramping and Spotting

Mild uterine cramping or light spotting often reflects implantation and ranks among classic signs of pregnancy before missed periods. Implantation typically occurs 6–10 days after ovulation, triggering localized inflammation and capillary disruption. That being said, many women do report cramping or spotting before their periods. “Implantation bleeding” is typically light pink or brown spotting that resolves quickly, and tends not to be bright red. Premenstraul bleeding gets progressively heavier. Cramping when you don’t usually experience it before your period (or during) is certainly something to pay attention to. That being said, women with adenomyosis or endometriosis are more likely to experience cramping during times of the month when they aren’t actively bleeding. Other causes of bleeding include luteal phase spotting from low progesterone, cervical irritation, or ovulation-related bleeding.

• Research Brief: There actually is no research identifying the prevalence of premenstrual cramping, meaning cramping that occurs before your period starts. Regarding spotting, only roughly 6% of women report premenstrual spotting. Notably, this isn’t normal and actually should be evaluated. (More on this in my book, Go with Your Flow.) On the other hand, approximately 25% of pregnant women are reported to experience vaginal bleeding in the first trimester.

At-Home Signs of Pregnancy Before Missed Periods

1. Cervical Position

Cervical height and texture change in response to estrogen and progesterone, making this a useful at-home marker among signs of pregnancy before missed period. During early pregnancy, the cervix tends to feel higher, softer, and more closed. When performing this self-check, make sure you have clean hands and a habit of checking cervical position before the two-week-wait when trying to conceive. Ovulation, arousal, and infection also influence cervical position. Learn more about checking cervical position for fertility or as an early sign of pregnancy in my book, Go with Your Flow.

2. Increased Basal Body Temperature (BBT)

Sustained elevation in basal body temperature ranks among the most objective signs of pregnancy before missed period. Progesterone raises resting temperature after ovulation; pregnancy maintains that rise beyond 14 days. One of the best ways to identify pregnancy without a urine test is with a sustained temperature past 18 days post-ovulation. This is an extremely accurate predictive method for those who regularly track their cycles with basal body temperature. Fever, alcohol intake, poor sleep, or thyroid imbalance also elevate BBT.

3. Increased Resting Heart Rate (RHR)

Resting heart rate often climbs early among signs of pregnancy before missed period due to increased metabolic demand and plasma volume expansion. Wearable devices (like a FitBit or Apple Watch) or morning pulse checks with a pulse oximeter are two ways to track RHR and identify changing patterns. A sustained increase of 3–10 beats per minute compared with baseline could be suggestive of early pregnancy. Because heart rate changes rapidly, this method is not as predictive or accurate as BBT. Dehydration, overtraining, illness, or stimulant use also raise RHR.

Lab-Based Signs of Pregnancy Before Missed Periods

Laboratory markers offer higher specificity among signs of pregnancy before missed period, especially when interpreted within clinical context. Of course the best and most accurate measure is with blood test for beta-hCG. However, I’ve accidentally identified pregnancy in patients who weren’t actively trying to get pregnant through these routine hormone blood tests.

1. High Prolactin

Prolactin supports breast development and milk production during early pregnancy. Nonpregnant reference ranges typically fall between 5–20 ng/mL. Early pregnancy often shows levels above 20–30 ng/mL. Prolactin is evaluated through a fasted morning blood test. However, high levels aren’t always a sign of pregnancy; elevated prolactin also appears with pituitary adenomas, hypothyroidism, chronic stress, or certain medications, so correlation matters.

2. Elevated Progesterone

Progesterone sustains the uterine lining and plays a central role in sustaining a pregnancy. Luteal phase values often range from 5–20 ng/mL, though they ideally sit between 12 and 20 ng/mL. Early pregnancy usually maintains levels above 10 ng/mL, often rising toward 20–40 ng/mL within weeks. Serum testing around 7–10 days post-ovulation offers useful insight. Supplement use, ovarian cysts, or timing errors also influence results.

Note: If you know you are pregnant and your progesterone level is lower than 15 ng/mL, this may be a miscarriage risk. Talk to your provider and learn more about ways to boost progesterone for fertility.

3. Rising Estrogen

Estradiol supports placental development and vascular growth, contributing to many signs of pregnancy before missed period. Typical luteal phase values range from 60–250 pg/mL. Early pregnancy often pushes levels above 200–600 pg/mL, with a steady upward trend. Blood testing works best when compared against prior cycle baselines. Estrogen dominance, ovarian hyperstimulation/cysts, or liver clearance issues also raise estradiol levels.

Putting the Signs Together

Of course, no single marker confirms pregnancy before a missed cycle unless that marker is directly testing hCG, the pregnancy hormone. However, a careful eye looking through a functional medicine lens can identify signs of pregnancy before missed periods by evaluating cycle history, nutrition, stress load, and metabolic health. When multiple symptoms, at-home observations, and lab trends align, it can help create hope during the two-week-wait.

If you’re seeking clarity, knowing the how’s and why’s behind these signs of pregnancy before your missed period empowers you to know your own body and understand your physiology on a deeper level. Tracking patterns over several cycles will improve the predictive power of these strategies and help you to know what is, and isn’t normal when deviations pop up. Of course, if you’re concerned about preconception signs and symptoms or anything else concerns you about your health, make an appointment with a trusted healthcare provider so that you don’t have to navigate your journey alone.

Search for a healthy whole grain bread recipe and you’ll quickly realize there’s a lot of confusion about what “healthy” even means when it comes to bread. Some people insist that all grains are inflammatory. Others point to traditional cultures that thrived on bread for centuries. Both perspectives miss important nuances. For most people, bread itself is not the problem. The type of grain, how it’s grown, how it’s processed, and how it’s prepared make all the difference.

A healthy whole grain bread recipe starts with a clear definition of health. Healthy bread avoids genetically modified grains, minimizes pesticide exposure, and excludes ultra-processed flours that have been stripped of nutrients. Healthy bread uses whole grains in their intact form, ideally from heirloom or ancient varieties to maximize nutrients, antioxidants, vitamins and minerals. Healthy bread relies on traditional preparation methods like fermentation and sourdough to improve digestibility and nutrient availability. Without these elements, calling something a “healthy whole grain bread recipe” could actually mean nothing at all in terms of true health.

Defining “Health” in a Healthy Whole Grain Bread Recipe

Health, in this context, means supporting metabolic function, gut health, immune regulation, and nutrient absorption. Modern bread often fails on all counts. Most commercial bread uses refined flour from genetically modified wheat grown with heavy pesticide use. The grain is processed at high heat, stored for long periods, and baked quickly with commercial yeast. The result is bread that spikes blood sugar, stresses digestion, and offers very little nutrition. Most ultra-processed breads from the grocery store also contain gut-damaging additives like preservatives, flavorings, dough conditioners and even hormone-disrupting chemicals like phthalates and even petroleum or plastic derivatives.

Yes, Whole Grain is Healthy

A healthy whole grain bread recipe uses whole grains that retain the bran, germ, and endosperm. These components contain fiber, minerals, healthy fats, and phytonutrients that refined flour simply does not provide. Using fresh milled flour matters because flour begins oxidizing the moment it’s ground. Fresh milling preserves nutrients that are otherwise lost during long storage times. Pre-ground flours also run the risk of growing mold, which is extremely damaging to gut health, provokes allergies, and can trigger autoimmune disease. We use the NutriMill Harvest Grain Mill, which is as easy as simply measuring the flour itself, only you measure the whole grains and pour it into the grinder first.

Leavening Matters

When it comes to maximizing nutrition with bread, fermentation is another non-negotiable. While most yeast breads look and taste similar, a truly healthy whole grain bread recipe relies on slow fermentation, often using sourdough, to break down antinutrients like phytic acid. (Phytic acid is considered problematic because it interferes with mineral absorption, especially when it’s consumed regularly in large amounts from poorly prepared grains, legumes, nuts, and seeds.) Fermentation improves mineral absorption and reduces digestive stress. This process also changes how carbohydrates behave in the body, improving blood sugar response and gut tolerance.

The Nutritional Benefits of Whole Grains

Whole grains provide fiber, B vitamins, magnesium, zinc, iron, and antioxidants that support metabolic and immune health. Fiber feeds beneficial gut bacteria, which directly influences inflammation, hormone balance, and insulin sensitivity. B vitamins play a role in energy production and nervous system function. Minerals like magnesium support blood sugar regulation and muscle function. Quality whole grains also serve as a slow-burning source of energy to fuel active lifestyles.

A healthy whole grain bread recipe delivers these nutrients in a form the body actually uses. When whole grains are fermented and prepared properly, the nutrients become more bioavailable. This is why traditional societies consumed bread daily without the metabolic dysfunction so common today.

Whole grains also contribute to satiety. Fiber and protein slow digestion and reduce rapid blood sugar swings. This matters for anyone trying to manage weight, energy levels, or cravings. Bread made from refined flour does the opposite.

Why Whole Grains Are Controversial in the Health Food Space

Whole grains have become controversial because many people feel better after eliminating them. That experience is real, but the conclusion often misses the root cause. Most people are not reacting to whole grains in general. They are reacting to modern wheat, industrial processing, pesticides, and poor preparation methods.

Ultra-processed grains disrupt the gut barrier, contribute to inflammation, and worsen blood sugar control. Removing them often leads to improvement. That doesn’t mean all grains are inherently harmful. A healthy whole grain bread recipe made from properly prepared, high-quality grains behaves very differently in the body.

Heirloom and ancient grain varieties deserve special mention. These grains differ genetically from modern dwarf wheat and contain different protein structures. Many people tolerate these varieties well, especially when fermented. Including these grains in a healthy whole grain bread recipe changes the entire physiological response.

Why Some People Tolerate Grains in Europe but Not the United States

This difference is not imaginary. Wheat grown in Europe differs significantly from wheat grown in the United States. Many European countries restrict glyphosate use and prohibit pre-harvest desiccation, a practice common in the U.S. where wheat is sprayed with herbicide shortly before harvest. The varieties of wheat grown differ, too. Europe primarily grows lower-gluten soft white wheat varieties whereas the US primarily grows hybridized and genetically modified varieties of hard red wheat which has higher gluten levels.

Processing standards also differ. European bread relies heavily on long fermentation and sourdough methods. In contrast, U.S. bread production prioritizes speed and shelf stability. A healthy whole grain bread recipe reflects traditional European preparation more than modern American convenience baking.

The result is that many people who struggle with bread in the U.S. tolerate bread abroad without symptoms. The grain, the chemicals, and the preparation all matter.

Who Actually Needs to Avoid Gluten?

Not everyone benefits from going gluten free. Gluten elimination is medically necessary for individuals with celiac disease and other diagnosed autoimmune diseases or sensitivities. It is often appropriate for those with Hashimoto’s thyroiditis, autoimmune disease, or diagnosed gluten or wheat sensitivities which are identified via IgE/IgA/IgG and IgG4 antibody testing. Outside of these conditions, blanket gluten avoidance is not automatically healthier, and often misses the heart of the issue. Gluten-free diets are also very restrictive, so it’s nice to know whether your issue is the GMO American wheat, or gluten in general.

In a healthy whole grain bread recipe, gluten formation plays a useful role. Gluten provides structure and elasticity, allowing bread to rise properly and maintain texture. Gluten also contributes protein, which helps stabilize blood sugar. When grains are fermented, gluten becomes easier to digest, reducing immune and digestive stress.

The problem arises when gluten is consumed in excess, from poor-quality sources, without fermentation, or in the context of other toxic ingredients found in ultra-processed foods. All of that matters.

Storage for Healthy Bread: Retrogradation

Storage matters more than most people realize. Freezing (and refrigerating) bread after baking improves the formation of resistant starch through a process called retrogradation. Resistant starch resists digestion in the small intestine and feeds beneficial gut bacteria in the colon.

A healthy whole grain bread recipe benefits from freezing because resistant starch supports gut health, improves insulin sensitivity, and reduces blood sugar spikes. Toasting frozen or previously refrigerated bread preserves these benefits while improving texture. It also extends shelf-life, which is an important consideration, given that homemade healthy bread doesn’t have preservatives.

Carbohydrate Awareness Still Matters

Even a healthy whole grain bread recipe contributes carbohydrates. Whole grains digest more slowly, but they still impact blood sugar. Portion size matters. Total carbohydrate intake includes fruit, vegetables, and starches, not just bread.

Health comes from balance, not extremes. Bread fits into a healthy diet when quality is high and total carbohydrate load stays appropriate for the individual.

A healthy whole grain bread recipe is not about restriction or fear. It is about choosing grains intentionally, preparing them traditionally, and consuming them with awareness. When those boxes are checked, whole grain bread supports metabolic health, gut function, and long-term wellness rather than undermining it.
