How Nutrient Deficiencies Impact Fertility and How to Address Them

Fertility is influenced by various factors, including diet, nutrient intake, exercise, and other lifestyle elements. Nutrient deficiencies can significantly impact reproductive health, making it essential to maintain a balanced and diverse diet. Understanding how specific nutrient deficiencies affect fertility, the importance of diet diversity, common deficiencies in dietary practices like veganism and vegetarianism, and best practices for supplementation, are crucial steps to increase your chances of growing your family.

The Importance of Diet Diversity

Diet diversity is crucial for obtaining the full range of recommended nutrients necessary for general health and fertility. A diet rich in a variety of foods (and color) ensures you get essential vitamins, minerals, and other nutrients that support reproductive health. However, certain dietary practices, such as veganism and vegetarianism, can lead to specific nutrient deficiencies if not carefully managed.

Common Nutrient Deficiencies in Vegan and Vegetarian Diets (or a Poor Diet) 

1. Calcium: Essential for bone health and reproductive function. In vegan diets, the absence of dairy can lead to low calcium intake.some text
   • Sources: Fortified plant-based milks, leafy greens like kale and collard greens, almonds, sesame seeds, chia seeds, amaranth, and tofu.
   • Pro-Tip: Pair vitamin D with calcium to help increase absorption.
2. Choline: Important for brain development and liver function. Often deficient in vegetarian diets that exclude eggs.some text
   • Sources: Eggs, soybeans, quinoa, and cruciferous vegetables.
3. Vitamin B12: Needed for nerve function and DNA synthesis. Lacking in vegan diets as it is primarily found in animal products.some text
   • Sources: Fortified cereals, nutritional yeast, and supplements.
4. Iron: Vital for oxygen transport and energy production. Plant-based sources of iron (non-heme iron) are less easily absorbed than animal sources.some text
   • Sources: Lentils, chickpeas, spinach, broccoli, quinoa, pumpkin seeds.
5. Omega-3 Fatty Acids: Important for hormone regulation and inflammation control. Often deficient in vegan diets lacking fish.some text
   • Sources: Flaxseeds, chia seeds, walnuts, and algae supplements.

Addressing Nutrient Deficiencies with Supplementation

Supplementation can be an effective way to address nutrient deficiencies, particularly for those following restrictive diets. Here are some best practices for supplementation:

1. Choose a Comprehensive Prenatal: Prenatal vitamins are designed to support fertility and pregnancy by providing essential nutrients in appropriate amounts.some text
   • Recommended Brands:some text
     • Perelel: Their trimester-specific approach ensures that women get the tailored nutritional support they need at each stage of pregnancy. 
     • Wenatal: prenatal supplements for women and men with the best-proven formula, backed by science.
2. Ensure Bioavailability: Bioavailable forms of nutrients are more easily absorbed and utilized by the body.some text
   • Folate vs. Folic Acid: Methylfolate, or 5-Methyltetrahydrofolate, is the active form of folate that the body can use directly.some text
     • Source: Look for supplements containing "Methylfolate," "5-MTHF," or "L-Methylfolate."
   • Iron: Choose supplements with iron bisglycinate, a form that causes fewer gastrointestinal side effects and is well-absorbed.some text
     • Source: Look for supplements containing "Iron Bisglycinate" or "Ferrous Bisglycinate."
     • Pro-Tip: Vitamin C helps increase absorption of iron, so look for these nutrients together. 
   • Calcium: Calcium citrate is better absorbed than calcium carbonate.some text
     • Source: Look for supplements labeled as containing "Calcium Citrate."
   • Vitamin D: Choose formulas including vitamin D3 (cholecalciferol) for better absorption.some text
     • Source: Look for supplements containing "Cholecalciferol" or "Vitamin D3."
3. Optimal Nutrient Amounts: Prenatal vitamins should provide nutrients in amounts that meet or exceed daily requirements without exceeding safe limits. Key nutrients to look for include:some text
   • Folate: At least 400-800 mcg of methylated folate.
   • Iron: 18-27 mg, depending on individual needs.
   • Calcium: 200-400 mg, though additional supplementation may be necessary.
   • Choline: 200-300 mg, particularly important if dietary intake is low.
   • Omega-3 Fatty Acids: 500-2,000 mg, often available in prenatal vitamins with added DHA.

Conclusion

Maintaining a nutrient-rich diet and addressing deficiencies through supplementation can significantly improve fertility and reproductive health. For individuals adhering to vegan or vegetarian diets, or those who find it challenging to adequately nourish themselves and feel depleted, it is important to be aware of potential nutrient gaps. Choosing high-quality, bioavailable supplements can help ensure all nutritional needs are met. Selecting a good prenatal can provide comprehensive support for preconception and pregnancy, helping to create the best possible foundation for a healthy pregnancy. As always, consult with your healthcare provider before starting any new supplement regimen to ensure it meets your individual health needs and is appropriate for your long-term goals.
