How Nutrigenomics Influences Fertility Your Genes (SNPs)

Your DNA blueprint, including unique variants, influences how your body processes key nutrients.

Nutrients & Diet

The foods you eat interact with your genes, affecting nutrient absorption, use, and balance.

Hormone Metabolism

Optimal nutrient availability tailored to your genetics supports balanced hormone production and clearance.

Fertility Outcomes

When hormones are balanced and nutrients are optimized egg quality, ovulation, and implantation can improve

CHAPTER 1: UNDERSTANDING NUTRIGENOMICS AND FERTILITY

6

What is Nutrigenomics?

Nutrigenomics examines how nutrients and other bioactive compounds in the foods you eat interact with your genes.

Certain genetic variants can affect how your body processes vitamins, minerals, and other nutrients.

By understanding these variants, you can tailor your diet and lifestyle to support optimal hormone balance and fertility.

Epigenetics 101 Epigenetics refers to changes in gene expression that occur without altering the DNA sequence itself.

Factors like stress, nutrition, toxins, and sleep can turn certain genes “on” or “off” This is great news: It means your daily choices can improve your fertility potential, even if you have

genetic predispositions.

CHAPTER 2: GENETIC SNPS THAT INFLUENCE FERTILITY

8

Common SNPs to Know for Your Fertility Health: Not all genetic variants have the same impact, but certain SNPs are known to influence hormone metabolism, nutrient utilization, and reproductive function.

•

MTHFR: Affects folate metabolism. Adequate folate is crucial for egg quality and reducing homocysteine, which can impact fertility and pregnancy outcomes.

•

COMT: Involved in estrogen and stress hormone metabolism. Efficient COMT function helps maintain balanced hormone levels.

•

VDR (Vitamin D Receptor): Influences how well your body uses vitamin D, a nutrient essential for follicular development and implantation.

•

FADS1/FADS2: Affect the conversion of plant-based omega-3s into their more active forms, impacting inflammation and hormone balance.

•

FTO: Influences metabolism and body weight regulation, which can play a role in ovulatory health.

CHAPTER 3: NUTRITION STRATEGIES FOR FERTILITY

11

Understanding Personalized Nutrition & Your Genes While there’s no one-size-fits-all fertility diet, understanding your SNPs helps you focus on the nutrients most important for you.

For instance, if you have an MTHFR variant, increasing leafy greens and lentils while (possibly) supplementing with methylated folate could be transformative.

12

10 Key Fertility Nutrients to Focus On: •

Folate (Vitamin B9): essential for proper cell division, DNA synthesis, and reducing the risk of neural tube defects. Adequate folate supports egg quality and early embryonic development.

•

Vitamin D: plays a vital role in hormone regulation and ovarian follicle development. Sufficient vitamin D levels are associated with improved fertility outcomes and a healthier pregnancy.

•

Omega-3 Fatty Acids (EPA & DHA): help reduce inflammation, support hormone balance, and may improve egg quality and implantation. Omega-3s also benefit overall reproductive health.

•

Iron: necessary for proper oxygen transport and energy production. Adequate iron levels help prevent anemia, support regular ovulation, and are linked to better fertility and pregnancy health.

•

Zinc: important for hormone production, ovulation, and maintaining egg quality. Zinc also supports a healthy immune system and may improve reproductive tract health.

•

Selenium: a potent antioxidant that helps protect reproductive cells from oxidative stress.

Selenium also supports thyroid function, which is closely tied to reproductive health.

•

Vitamin B12: works closely with folate to support DNA synthesis and red blood cell formation.

Adequate B12 is linked with improved fertility and early pregnancy outcomes.

•

Iodine: crucial for proper thyroid hormone production. A well-functioning thyroid supports regular menstrual cycles, ovulation, and overall hormone balance.

•

Magnesium: involved in over 300 enzymatic reactions in the body. It helps regulate stress, blood sugar, and hormone metabolism, all of which are essential for optimal fertility.

•

Choline: supports fetal brain and spinal cord development and is involved in methylation processes. Adequate choline intake may improve egg quality and early embryonic development.

CHAPTER 6: The Thyroid Connection

25

How Does the Thyroid Factor Into Fertility & Genetics?

Optimal thyroid health is crucial for fertility as it underpins hormone balance, regular menstrual cycles, and proper ovulation, thereby influencing a woman’s ability to conceive and maintain a healthy pregnancy.

26

The Importance of Thyroid Health Thyroid health is deeply interconnected with a woman’s fertility and hormonal balance.

The thyroid gland produces hormones (T3 and T4) that regulate metabolism, influence ovulation, and affect the health of the uterine lining. When the thyroid is underactive (hypothyroidism) or overactive (hyperthyroidism), it can cause irregular menstrual cycles, difficulty conceiving, and even complications during pregnancy.

Additionally, imbalances in thyroid hormones may interfere with the delicate interplay between the brain’s signaling hormones and the ovaries, potentially leading to disrupted ovulation and lowered progesterone levels—both key factors in achieving and maintaining a healthy pregnancy.

Optimizing thyroid function can improve energy levels, stabilize mood, and support a more regular menstrual cycle, all of which are crucial for fertility Ensuring adequate intake of nutrients like iodine, selenium, zinc, and vitamin D is essential for proper thyroid hormone production and conversion. Likewise, managing stress, incorporating gentle exercise, and addressing gut health can foster an environment where the thyroid can thrive.

By placing a priority on thyroid health, women set a strong foundation for hormonal balance, more predictable ovulation, and enhanced fertility outcomes.

27

Your thyroid is the gland that acts like your body's thermostat.

When metabolism is too low, your brain initiates a hormone cascade to “turn up the heat”. When your metabolism is too high, thyroid hormones will be deactivated so they cannot signal.

A healthy thyroid can respond to these fluctuations and keep everything in balance.

28

29

Thyroid dysfunction is either HYPO (too low) or HYPER (too high).

30

Thyroid Markers *tested with complete thyroid panel

THYROID RELEASING HORMONE

when the TRH signal is “off”, so is the rest of the cascade

THYROID STIMULATING HORMONE* if TSH is really high or really low, then the thyroid is likely not receiving its signals

TOTAL T4 & T3* bound & circulating levels of thyroid hormones that give a general idea of thyroid function

FREE T4 & T3* unbound & circulating levels of thyroid hormones that can signal to body cells

THYROID BINDING GLOBULIN* too much TBG will bind & prevent T4 & T3 from signaling

THYROID ANTIBODIES*

TPO, TG, and TSHR antibodies are high when the body starts to attack the thyroid, often before any other symptoms are present

31

10 Nutritional and Lifestyle Strategies that Support Optimal Thyroid Function: 1.

Ensure Adequate Iodine Intake: Iodine is a key building block of thyroid hormones. Including sea vegetables (like kelp), iodized salt (in moderation), or supplementation under medical guidance can maintain adequate iodine levels.

2.

Optimize Selenium and Zinc: These minerals help convert T4 to the more active T3 hormone and protect against oxidative stress. Brazil nuts (for selenium), pumpkin seeds, and oysters (for zinc) are good sources.

3.

Get Enough Vitamin D: Adequate vitamin D supports proper thyroid hormone receptor function.

Moderate sun exposure, fatty fish, or supplementation can help maintain healthy levels.

4.

Consume Quality Protein and Healthy Fats: Lean proteins (eggs, fish, legumes) and healthy fats (avocado, extra-virgin olive oil) support hormone synthesis and overall metabolic health.

5.

Balance Blood Sugar: Stabilizing blood sugar through balanced meals rich in fiber, protein, and healthy fats can reduce stress on the body, indirectly supporting thyroid function.

6.

Limit Goitrogens in Excess: Foods like raw cruciferous vegetables (kale, broccoli) can interfere with thyroid hormone production if eaten in very large amounts. Lightly cooking them reduces this effect.

7.

Support Gut Health: A healthy gut microbiome influences thyroid hormone metabolism.

Fermented foods (yogurt, sauerkraut) and prebiotic fibers (onions, garlic) can promote a balanced microbiome.

8.

Manage Stress Levels: Chronic stress increases cortisol, which can hinder thyroid hormone conversion and receptor sensitivity. Mindfulness, yoga, or short nature walks can help lower stress.

9.

Engage in Moderate Exercise: Regular physical activity supports healthy metabolism, improves insulin sensitivity, and can positively influence thyroid hormone levels and function.

10. Prioritize Sleep: Aim for 7–9 hours of quality sleep, as poor sleep can disrupt the hypothalamicpituitary-thyroid axis and lead to hormone imbalances that affect thyroid health.

CHAPTER 8: RESOURCES AND NEXT STEPS

36

Where to Get Tested & Considerations When Choosing A Company: •

It is important to remember that not all lab testing companies are accurate in the interpretation of your genetic data. For instance, 23andme, a popular genetics company has about 50% accuracy in the assessment of genes.

•

Choose reputable genetic testing labs such as 3x4 Genetics and Intellxx DNA. These are companies I use in my practice!

•

Partner with holistic clinicians or functional medicine practitioners who can interpret results.

37

Before purchasing genetic lab services from a company, it’s essential to understand their data handling and privacy policies. Consider these following points:

1.

Data Ownership and Usage: Clarify who owns your genetic data after testing and how the company may use it for research, product development, or third-party partnerships. Ask whether they share or sell de-identified data to external organizations.

2.

Privacy Policies and Confidentiality: Review their privacy policy to ensure it aligns with rigorous standards. Check if they comply with regulations like HIPAA (in the U.S.) or GDPR (in the EU), and understand what safeguards are in place to prevent unauthorized access to your genetic information.

3.

Data Storage and Security Measures: Find out where and how your data will be stored, whether it’s encrypted, and what security protocols they follow to protect against breaches. Ask if they have a clear data retention policy and a plan for data deletion at your request.

4.

Re-Testing and Secondary Analysis: Confirm if you can request the raw genetic data and whether you have the option to delete it or have it re-tested or analyzed by another provider. Understand any potential costs associated with additional services.

5.

Scientific Validity and Accreditation: Check the company’s credentials— whether their labs are CLIA-certified or accredited by reputable organizations. Inquire about the scientific validity and accuracy of their tests, how they ensure quality control, and if they involve trained genetic counselors or healthcare professionals for result interpretation.

6.

Transparency and Communication: Look into how clearly the company communicates its testing methods, limitations, and the meaning of results.

Determine if they offer support, such as genetic counseling or customer service, to help you understand your data.

7.

Policies on Updates and Changes: Understand what happens if the company updates their analysis or discovers new insights. Will they notify you, and can you opt in or out of receiving updated interpretations?

38

CONCLUSION Your genes provide a roadmap—an inside look at how your body processes nutrients and influences your fertility. By leveraging nutrigenomics, you’re no longer in the dark about why certain diets or supplements may not have worked in the past. Instead, you can tailor your approach to what your body truly needs.

Remember, small, consistent changes lead to profound transformations.

Your DNA is just a starting point. Armed with this knowledge, you can rewrite your health story and move confidently toward your fertility goals.

“Your DNA is not your destiny—take charge of your fertility journey today!”
