Planning to conceive involves considering various factors such as the fertile window, egg and sperm health, and hormone levels. Anti-Müllerian Hormone (AMH) is a crucial hormone that indicates ovarian reserve and egg quality. AMH levels reflect the number of eggs remaining in the ovaries, which naturally decrease with age. While age is a significant factor, lifestyle and environmental elements also play a role in ovarian reserve. This article examines how diet and lifestyle adjustments can naturally impact AMH levels and improve fertility.
Understanding AMH and Its Significance
AMH, produced by small ovarian follicles, serves as a key indicator of a woman's egg reserve. Higher AMH levels typically suggest a larger egg reserve, enhancing the chances of conception. Low AMH levels, particularly below 1.0 ng/mL, can indicate a diminished ovarian reserve, potentially making conception more challenging but not impossible. AMH levels remain relatively stable throughout the menstrual cycle, making it a reliable marker for assessing ovarian reserve.
The Impact of Diet on AMH Levels
Diet plays a pivotal role in reproductive health, influencing menstrual cycle length, follicular depletion, and inflammation. Research suggests that dietary fat intake may be inversely associated with AMH concentrations. A study involving 296 women aged 35-45 years revealed significant associations between dietary factors and serum AMH concentrations.
Key Findings from the Sister Study Cohort
The Sister Study cohort, which included women aged 35-45 years, examined the relationship between diet and AMH levels. The study assessed dietary intakes over the past 12 months using a validated food frequency questionnaire, focusing on macronutrients, dietary fat subtypes, fiber, and glycemic index.
- Carbohydrates: AMH concentrations were positively associated with the percentage of energy from carbohydrates. Specifically, a 5% increase in calories from carbohydrates was associated with an increase in AMH levels.
- Fats: Conversely, AMH levels were inversely associated with the percentage of energy from fat. A 5% increase in calories from fat was linked to a decrease in AMH levels.
- Fat Subtypes: Increasing monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs), especially ω−6 fatty acids, was associated with decreased AMH levels. Saturated fatty acids did not show a strong trend.
- Nutrient Density Models: Replacing energy from carbohydrates with energy from fat was associated with lower AMH concentrations, while replacing energy from fat with carbohydrates was positively associated with AMH.
These findings suggest that a diet higher in carbohydrates and lower in fats may help maintain or improve AMH levels in late premenopausal women.

Practical Dietary Recommendations
To support healthy AMH levels and overall fertility, consider the following dietary recommendations:
- Prioritize a Balanced Diet: Focus on incorporating fresh fruits and vegetables, whole grains, and lean proteins. These foods provide essential nutrients that support overall health and reproductive function.
- Increase Carbohydrate Intake: Choose complex carbohydrates like whole grains, fruits, and vegetables over simple sugars and processed foods.
- Reduce Fat Intake: Limit the consumption of total fats, particularly monounsaturated and polyunsaturated fatty acids.
- Incorporate Fertility Superfoods: Include berries, leafy greens, and nuts in your diet, as they are packed with nutrients that support reproductive health.
- Ensure Adequate Vitamin D: Vitamin D deficiency has been linked to low AMH levels. Consume vitamin D-rich foods like fatty fish, egg yolks, and fortified dairy products, and spend time in the sun.
- Increase Omega-3 Fatty Acids: While the study indicated an inverse association between PUFAs and AMH, omega-3 fatty acids are still beneficial for hormone regulation and overall reproductive health. Good sources include flaxseeds, walnuts, and oily fish.
- Consume Foods High in Antioxidants: Colorful fruits and vegetables provide a range of antioxidants that protect egg health.
- Include Zinc-Rich Foods: Oysters, pumpkin seeds, and lean meats are rich in zinc, an important mineral for reproductive health.
- Increase Folate Consumption: Leafy greens, legumes, and fortified grains contain folate, a fertility-friendly vitamin.
- Add Fertility-Friendly Fats: Healthy fats from avocados, olive oil, and nuts support endocrine system function.
- Boost Iron Intake: Iron is crucial for ovulation and is found in lean meats, beans, and spinach.
- Boost Your B Vitamin Intake: B vitamins generally promote reproductive health and are found in whole grains, eggs, and leafy green vegetables.
- Rich in Selenium: Brazil nuts, seafood, and whole grains are rich in selenium, an essential mineral to maintain fertility and boost thyroid activity.
Lifestyle Factors Influencing AMH Levels
Beyond diet, several lifestyle factors can impact AMH levels and overall fertility.
Exercise and Weight Management
Maintaining a healthy weight is crucial, as being underweight or overweight can lead to hormonal imbalances, including altered AMH levels. Regular, moderate exercise can help maintain a healthy weight and improve hormone levels and ovarian function.
- Embrace Regular Exercise: Engage in moderate-intensity exercise for at least 30 minutes a day, five days a week.
- Maintain a Healthy Weight: Strive to stay within a healthy weight range based on your Body Mass Index (BMI).
Stress Management
Chronic stress can disrupt hormonal balance and negatively affect egg quality. Implementing stress-reduction techniques can help manage stress and improve reproductive health.
- Manage Stress Effectively: Practice relaxation techniques such as meditation, yoga, and deep breathing exercises.
- Mindfulness Meditation: Incorporate mindfulness meditation to reduce stress and promote overall well-being.
- Acupuncture: Some studies suggest that acupuncture can help improve ovarian function and increase AMH levels.
Sleep and Rest
Sufficient sleep is essential for hormone balance and overall health. Aim for 7-9 hours of quality sleep per night.

- Get Enough Sleep: Ensure high-quality sleep for about 7-8 hours every day.
Avoiding Harmful Substances
Certain substances can negatively impact ovarian reserve and AMH levels.
- Limit Alcohol and Caffeine: Excessive alcohol and caffeine consumption can negatively impact fertility.
- Avoid Smoking: Smoking has detrimental effects on ovarian function and can significantly lower AMH levels. Minimize exposure to secondhand smoke as well.
The Role of Supplements
While supplements should not replace a healthy diet, certain supplements may support ovarian health and potentially help maintain AMH levels.
- Take Supplements if Needed: Consult a specialist to check for any deficiencies and consider supplements that support ovarian health, such as Vitamin D, CoQ10, DHEA (under strict medical supervision), NAC (N-Acetyl Cysteine), and Omega-3 fatty acids.
- Vitamin D: For reproductive function.
- CoQ10: For egg quality.
- DHEA: Under strict medical supervision.
- NAC (N-Acetyl Cysteine): For antioxidant support.
- Omega-3 Fatty Acids: For hormone regulation.
- Consider Targeted Supplements: Other supportive supplements may include L-arginine, vitamin E, selenium, pine bark extract, choline, and magnesium.
It is crucial to consult with a healthcare provider before starting any supplement regimen, as some supplements may interact with medications or may not be suitable for everyone.
Medical Treatments and Interventions
If natural remedies and lifestyle changes are insufficient, medical treatments may be considered.
In-Vitro Fertilization (IVF)
IVF involves hormone therapy to stimulate the ovaries to produce eggs, which are then extracted. This can be an option for women with low AMH levels who are struggling to conceive.

Egg Donation
For women with very low ovarian reserves or other conditions, egg donation may be a viable option.
