The Most Important Nutrients for Fertility

In Priming the Bump, my 14-day fertility prep program, meals are tailored to include nutrients that are known to improve fertility: Protein; Vitamins A, B, C, D, and E; Zinc & Selenium; carnitine & arginine; omega-3 fatty acids; probiotic foods, and antioxidants. 

Want to know exactly how these fertility super-nutrients support your reproductive system? Here is the rundown:

Vitamins

• Vitamin A: Necessary for the production of estrogen, progesterone & testosterone. Vitamin A also protects against environmental toxins & aids sperm production.
• B-vitamins (especially folate & B12): Folate is crucial upon conception and many women are deficient. B vitamins (especially folate & B12) are responsible for protecting the DNA within sperm.
• Choline: Choline is usually grouped with the B-complex vitamins. It is critical for brain & nervous system development.
• Vitamin C: Vitamin C improves all semen variables. Vitamin C deficiency has been linked to declines in sperm count, motility and vitality and to an upswing in abnormal sperm.
• Vitamin D: Balances Vitamin A, supports the production of estrogen in men & women, and can help correct PCOS. Infertility is associated w/ low levels of D.
• Vitamin E: A powerful tool to improve male & female fertility, Vitamin E also increases male potency, regulates menstrual flows, and may prevent miscarriage.

Antioxidants
Antioxidants are essential for everyone during this age of high free radical damage, but they're especially important for anyone struggling with fertility. They help protect your delicate reproductive cells and systems from oxidation and degeneration. In fact, high antioxidant intake is known to improve fertility. Antioxidant consumption is associated with an increase in pregnancy rates, and it may also aid fertility in older women.

Many nutrients have antioxidant capabilities, but some of the most potent antioxidants are Vitamins A, C, and E, Selenium and Zinc.

Minerals

• Selenium: Selenium is considered essential for male fertility because of its role in testosterone synthesis, normal sperm maturation, and sperm motility.
• Zinc: Another critical mineral for male sexual function, Zn is involved in virtually every aspect of male reproduction. But it's not just for men. Zinc is also required for estrogen, progesterone & sperm production. Impotence, infertility or sterility can occur from Zn deficiency, and deficiency during pregnancy can cause birth defects.
• Bone broth contains minerals like calcium. It also supplies nutrients that help build healthy cartilage, detoxify, and heal the digestive tract. It's an excellent tonic for immunity as well as development.

Brazil nuts are an excellent food source of Selenium, and oysters are the best dietary source of Zinc. It's no wonder oysters are considered an aphrodisiac!

Protein

• Clean protein: Reproductive hormones are made from proteins, some of which are only obtainable through diet (aka "essential"). Protein also provides a feeling of satiety that helps us stay on track and avoid a doughnut binge.
• Carnitine: Carnitine is an amino acid - one of protein's building blocks. Low carnitine levels may be indicative of infertility. Carnitine can help men improve their sperm count & motility. It also provides energy to testicles and sperm.
• Arginine: An amino acid that is essential for sperm formation. Arginine can strengthen sperm count & motility. It can also improve fertilization rates in women who had previously failed IVF.

Fat

• High-fat dairy products: Studies show that high-fat dairy reduces the risk of infertility due to lack of ovulation by more than 50% in contrast to low-fat dairy foods, which can actually reduce the risk of successful conception.
• Omega-3 fatty acids: Sperm motility directly correlates with omega-3 fatty acid levels, especially DHA. Too few omega-3 fatty acids in relation to omega-6 fatty acids can decrease sperm concentration, motility & morphology. Plus, omega-3s are crucial for baby's brain development.

Probiotics

• Probiotic foods: Changes in vaginal flora & subsequent genital & intrauterine infections have been linked to reproductive failure. Probiotic foods help restore bacterial balance. In addition, since probiotics help us digest & assimilate food, they help ensure that the body can use all the nutrients we eat. Probiotics can also detoxify & strengthen the immune system, which is especially important during the early stages of pregnancy.

Now that you know which nutrients are important for fertility (and why), you can begin to choose foods that supply these nutrients and begin boosting your fertility naturally.

Low Progesterone? Do This.

Progesterone works in partnership with estrogen throughout a woman’s cycle to prepare the uterus for conception. Estrogen is the dominant hormone during the first part of a woman’s cycle (the follicular phase), while progesterone is the dominant hormone during the last part (the luteal phase). The two hormones must be in balance to achieve optimal health.

If you’ve been charting your cycles, you can see where progesterone takes over - it’s responsible for the rise in your temperature.

Not sure if you have low progesterone? Check out Katie Singer’s book The Garden of Fertility for tips on how to read your charts to find out whether they might indicate low progesterone levels.

Low progesterone is quite common. It’s actually not surprising when you consider that estrogenic compounds are everywhere nowadays - in our environment, food, plastics, personal care products, and more. And the higher estrogen is, the more progesterone we need to be in balance.

If you’d like to avoid synthetic progesterone shots & creams, there are some natural alternatives you can try to boost your progesterone level (and/or reduce your estrogen level):

• Cut out dairy. One Harvard scientist & physician found that dairy accounts for 60-80% of estrogens consumed!
• Go organic. Minimizing pesticides and hormones in your food can help avoid estrogen overload.
• Eliminate other estrogenic compounds. Stop eating phytoestrogens like soy (click here for food sources), and stop using plastics and personal care products that could leach xenoestrogens (click here to find out where they’re lurking and how to avoid them).
• Stop eating sugar and refined carbohydrates. Consumption of refined carbohydrates can indirectly exhaust your adrenals, suppressing progesterone1.

If further supplementation is required, you might ask your doctor about natural or bio-identical progesterone from a compounding pharmacy.
