Prenatal Pro? provides optimal supplementation for pregnant women, lactating women, and women wishing to become pregnant. The earlier that supplementation begins, the better, because women need adequate nutrient stores to meet the greater nutrient demands for a growing baby. This prenatal multivitamin provides folate in the bioidentical, bioactive form, 5-methyltetrahydrofolate (L-5MTHF) in place of synthetic folic acid. L-5MTHF is the active circulating form of folate found in the body and one of the several forms found in food.
