Antioxidants, Vitamins & Minerals for Fertility

Folic Acid: Perhaps one of the best known vitamins necessary for pregnancy is folic acid. This vitamin helps prevent neural tube defects as well as congenital heart defects, cleft lips, limb defects, and urinary tract anomalies in developing fetuses. Deficiency in folic acid may increase the risk of going into preterm delivery, infant low birth weight and fetal growth retardation. Deficiency may also increase the homocysteine level in the blood, which can lead to spontaneous abortion and pregnancy complications, such as placental abruption and pre-eclampsia.

Food sources: liver, lentils, pinto beans, garbanzo beans, asparagus, spinach, black beans, navy beans, kidney beans, collard greens

Iron: Studies have shown that women who do not get sufficient amounts of iron may suffer anovulation (lack of ovulation) and possibly poor egg health, which can inhibit pregnancy at a rate 60% higher than those with sufficient iron stores in their blood.

Food sources: Lentils, spinach, tofu, sesame seeds, kidney beans, pumpkin seeds (raw), venison, garbanzo beans, navy beans, molasses, beef

B6: Vitamin B6 may be used as a hormone regulator. It also helps to regulate blood sugars, alleviates PMS, and may be useful in relieving symptoms of morning sickness. B6 has also been shown to help with Luteal Phase Defect.

Food sources: Tuna, banana, turkey, liver, salmon, cod, spinach, bell peppers, and turnip greens, collard greens, garlic, cauliflower, mustard greens, celery, cabbage, asparagus, broccoli, kale, Brussels sprouts, chard.

B12: Vitamin B12 has been shown to improve sperm quality and production. It also may help to boost the endometrium lining in egg fertilization, decreasing the chances of miscarriage. Some studies have found that a deficiency of B12 may increase the chances of irregular ovulation, and in severe cases stop ovulation altogether.

Food sources: Clams, oysters, muscles, liver, caviar (fish eggs), fish, crab, lobster, beef, lamb, cheese, eggs.

Vitamin C: Vitamin C improves hormone levels and increases fertility in women with luteal phase defect, according to a study published in “Fertility and Sterility”. As for men, vitamin C has been shown to improve sperm quality and protect sperm from DNA damage; helping to reduce the change of miscarriage and chromosomal problems. Vitamin C also appears to keep sperm from clumping together, making them more motile.

Food sources: Abundant in plants and fruits including red peppers, broccoli, cranberries, cabbage, potatoes, tomatoes, and citrus fruit.

Vitamin D: Vitamin D is needed to help the body create sex hormones which in turn affects ovulation and hormonal balance. Yale University School of Medicine conducted a study of 67 infertile women, where it was discovered that a mere 7% had normal Vitamin D levels.

Food sources: Eggs, fatty fish, dairy, and cod liver oil. You can also get vitamin D from sitting out in the sun for 15 to 20 minutes per day. But absorption is impacted by the darkness of your skin.

Vitamin E: Has been shown in studies to improve sperm health and motility in men. Studies have shown a diet deficient in Vitamin E to be a cause of infertility in rats. The meaning of the name for vitamin E ‘Tocopherol’ literally means to bear young. Vitamin E is also an important antioxidant to help protect sperm and egg DNA integrity.

Food sources: Sunflower seeds, almonds, olives, spinach, papaya, dark leafy greens.

CoQ10: Necessary for every cell in the body having energy to function, CoQ10 has also been shown in studies to increase sperm motility in semen. It is also an important antioxidant that helps to protect cells from free radical damage. This may impact egg health as well.

Food sources: Found in seafood and organ meats. Amounts in the body decline with age.

Lipoic Acid: Lipoic acid is a very important antioxidant because it not only helps to protect the female reproductive organs and has been shown to improve sperm quality and motility but it also helps the body to continually re-use the antioxidants in the body.

Food sources: In small amounts found in potatoes, spinach and red meat.

Selenium: An antioxidant that helps to protect the eggs and sperm from free radicals. Free radicals can cause chromosomal damage which is known to be a cause of miscarriages and birth defects. Selenium is also necessary for the creation of sperm. In studies men with low sperm counts have also been found to have low levels of selenium.

Food sources: Liver, snapper, cod, halibut, tuna, salmon, sardines, shrimp, crimini mushrooms, turkey

Zinc: In women, zinc works with more than 300 different enzymes in the body to keep things working well. Without it, your cells can not divide properly; your estrogen and progesterone levels can get out of balance and your reproductive system may not be fully functioning. Low levels of zinc have been directly linked to miscarriage in the early stages of a pregnancy, according to The Centers for Disease Control’s Assisted Reproductive Technology Report.

In men zinc is considered one of the most important trace minerals to date for male fertility; increasing zinc levels in infertile men has been shown to boost sperm levels; improve the form, function and quality of male sperm and decrease male infertility.

Food sources: Calf liver, oysters, beef, lamb, venison, sesame seeds, pumpkin seeds, yogurt, turkey, green peas, shrimp. Zinc can be damaged by cooking so it is important to eat some foods high in zinc in their raw forms.

Essential Fatty Acids: Omega-3 acids have been shown to help fertility by helping to regulate hormones in the body, increase cervical mucous, promote ovulation and overall improve the quality of the uterus by increasing the blood flow to the reproductive organs.

Omega-3 fats also contain two acids that are crucial to good health: DHA and EPA. These two acids have been shown to help many forms of disease. Low levels of DHA have been linked to depression and other mental health issues. During pregnancy, a lack of DHA may be associated with premature birth, low birth weight and hyperactivity in children.

Food sources: Flax seeds, walnuts, salmon, sardines, halibut, shrimp, snapper, scallops, chia seed.

Macronutrients

In addition to the micro-nutrients, macro-nutrients are important as well. Getting enough protein, fiber, fat, carbohydrates, etc. is also very important. This is a time for nourishing and providing building blocks for your body in preparation for conception. The foods that should be focused on in a Natural Fertility Diet are nutrient dense foods which help to provide the following:

Fats
A wide variety of fats are very important for fertility and the development of the fetus. Not only are essential fatty acids important but saturated fats and cholesterol are important as well. Cholesterol is a pre-curser to all hormones produced in the body including progesterone. Just make sure it is from the right foods like coconut oil, grass-fed meats, fish, nuts and seeds and avoid hydrogenated oils and vegetable oils cooked at high heat.

Fiber
Fiber helps assist the body in getting rid of excess estrogen and xenohormones in the system and keeps your digestive tract functioning properly.

Proteins
Eating healthy amounts of protein from a wide variety of sources is an important part of a healthy fertility diet as amino acids are the building blocks for cells in the body. Make sure to include both animal sources and vegetable sources of protein daily.
