Low AMH Levels: The Functional Nutrition Blueprint for Better Fertility Outcomes

Low AMH is an often misunderstood fertility marker. While it offers helpful insight into ovarian reserve, it does not determine whether or not you can get pregnant naturally. Still, seeing a low AMH value on your lab report can feel overwhelming and concerning if you are trying to conceive. 

In this blog, we’ll break down what AMH actually measures and how functional nutrition can support egg quality and ovarian function, two factors that matter most for fertility, especially if AMH levels are low.

What is AMH? Let’s Better Understand This Fertility Marker

AMH, or Anti-Müllerian Hormone, is produced by cells that surround early-developing follicles (think “egg sacs”) in the ovaries. These small follicles release AMH as they grow. Therefore, the more follicles or eggs in the ovaries, the higher AMH levels will be in the blood. AMH is a useful indicator of ovarian reserve and reflects potential for future follicle growth, but it’s not a physical egg count or a direct measure of fertility potential.

AMH naturally declines with age because the follicle pool declines over time. Women are born with one to two million follicles, but this number drops to around 400,000 by puberty. Each ovulatory menstrual cycle nearly 1,000 follicles begin developing, though typically only one is selected to mature enough to ovulate. Those that aren’t selected are then degenerated by a process called apoptosis, or controlled self-destruction. By menopause, fewer than 1,000 follicles remain, and AMH becomes nearly undetectable.

What Is An Ideal AMH Level?

Although AMH is relatively stable throughout the menstrual cycle, levels can fluctuate slightly and peak around ovulation, so it’s recommended to test around cycle day 2-3. Optimal AMH ranges differ by age and can vary between 1-6 ng/mL. 

When of reproductive age, we consider an AMH level 3-6 ng/mL to be optimal. AMH levels above 6 ng/mL can point to polycystic ovarian syndrome (PCOS) due to an excess of immature follicles. On the other hand, levels below 3 ng/mL can be indicative of decreased egg quality, and below 1 ng/mL may point toward diminished ovarian reserve (DOR) or primary ovarian insufficiency (POI).

Most importantly, AMH alone cannot diagnose DOR or POI – deeper investigation is required. And low AMH levels do not mean you cannot get pregnant naturally. AMH is just one part of a much bigger fertility story and must be interpreted alongside hormone data, cycle patterns, and your overall health picture.

Can You Improve AMH Levels?

Now that we have a better understanding of what AMH reflects, let’s clarify whether or not AMH levels can actually be improved! 

We know that AMH represents, but doesn’t directly measure, egg quantity. And egg quantity itself cannot be increased. In someone who is perimenopausal who has already experienced a significant decrease in ovarian reserve, we can expect AMH levels to be low and only continue to diminish. 

However, in young women with low AMH, there are often other factors at play that are influencing ovarian function. Non-age-related drivers of low AMH include autoimmune conditions, endometriosis, high levels of oxidative stress, as well as chronically high cortisol levels and HPO (hypothalamus-pituitary-ovary) axis dysfunction. 

All of these factors can impact ovarian function, follicle development, and therefore AMH levels. By supporting follicle and egg quality, mitochondrial function, oxidative stress levels, and hormone production, fertility outcomes can significantly improve, even in spite of low AMH levels. This is where functional nutrition becomes a powerful partner in your fertility journey.

Why Mitochondria Matter for AMH and Egg Quality

Mitochondria are the driving force behind ovary and egg health. Eggs are the most mitochondrial-dense cells in the human body, containing over 100,000 mitochondria per oocyte, or egg cell. 

Mitochondria have incredibly important responsibilities, from producing cellular energy (ATP) and supporting DNA replication, to ensuring cell division occurs properly. In short, every aspect of fertility, from preconception to implantation and embryo development relies on the health of our mitochondria.

Mitochondrial function declines due to age, chronic stress, toxin exposure or buildup, nutrient insufficiencies, immune dysregulation, and overexercising, to name a few. Under these conditions, the ovarian environment becomes less resilient, which can impair follicle recruitment and contribute to lower AMH levels.

Functional nutrition plays a powerful role in supporting mitochondrial health by replenishing mitochondrial cofactors, combating oxidative stress with potent antioxidants, and optimizing energy availability. Together, these strategies support egg quality, making the most of current ovarian reserves.

Top 4 Functional Nutrition Strategies to Support Low AMH Levels

1. Optimize Energy Availability for Ovarian Function

Adequate energy intake is essential for healthy ovulation and hormone production. Chronic under-eating, low-carb diets, and not fueling properly around exercise can suppress the HPO axis, considering that the hypothalamus is quite sensitive to energy deficits. This leads to ovarian dysfunction and reduced follicle recruitment.

Key strategies:

• Aim to eat consistent balanced meals or snacks every 4-5 hours.
• Eat plenty of protein spread throughout the day (about 1.5-2 grams per kilogram of body weight, although individual needs differ).
• Don’t skip the fat, given that cholesterol is a crucial component of reproductive hormones.
• Choose fiber-rich carbs for each meal like lentils, beans, sweet potatoes, and root vegetables. Carbs are essential for adequate T3 and leptin formation, two hormones that are essential for healthy HPO axis function.

2. Address “Energy Leaks” that are Impairing Mitochondria

Chronic biological stressors like mold, viral infections, and gut dysbiosis keep the immune system overactivated, creating an “energy leak” that drains mitochondrial resources and diverts energy away from hormone production. Because immune activity is highly energy-dependent, reducing these burdens and replenishing nutrients are essential steps to refuel mitochondria, restore balance, calm inflammation, and support ovarian function.

Key areas to investigate:

• Mold mycotoxin exposure or bioaccumulation
• Chronic infections (such as Epstein-Barr Virus (EBV), Herpes Simplex Virus (HSV), and parasitic infections)
• Gut dysbiosis or microbiome imbalances

3. Antioxidant Support to Reduce Oxidative Stress in the Ovaries

Oxidative stress is a major driver of poor egg quality, hormone dysregulation, and fertility challenges. By flooding the body with antioxidants, you can help offset oxidative stress by neutralizing harmful free radicals. While antioxidants are widespread in food sources, targeted supplementation can offer additional potent antioxidant support.

Key antioxidants:

• CoQ10 enhances mitochondrial function and egg quality; found in highest concentrations in organ meats and animal-based proteins.
• Vitamins C & E improve ovarian cell function for healthier follicle development and protect follicles from oxidative stress; found in citrus fruits, bell pepper, kiwi, avocado, nuts, and seeds
• Glutathione is the “master antioxidant” in the body that reduces inflammation and supports detoxification; foods rich in sulfur support glutathione production, like onions, garlic, broccoli sprouts, broccoli, cauliflower, and cabbage. 

4. Inositol for Hormone Signaling and Egg Quality

Inositol is a hormone-supportive carbohydrate that enhances hormone signaling, improves blood sugar regulation, and directly supports follicle development. It helps the ovaries respond to upstream hormone signals, thus supporting communication along the HPO axis. It also has antioxidant properties and supports mitochondrial energy production in the ovaries. 

Key inositol takeaways:

• Both myo-inositol and D-chiro-inositol are helpful if low AMH levels are paired with irregular cycles, insulin resistance, or PCOS.
• Myo-inositol is especially helpful for those with thyroid dysfunction and thyroid autoimmunity, as it’s been shown to help decrease TPO antibodies.

The Bottom Line: Low AMH Doesn’t Define Your Fertility Future

While a low AMH value can feel discouraging, it is not the final word on your fertility potential. It’s important to dive deeper into why AMH levels may be low, especially if age doesn’t seem to be the only culprit.

With the right functional nutrition approach, women with low AMH can significantly improve egg quality, hormone balance, and overall fertility outcomes. After all, your fertility is not defined by AMH alone.
