How much folic acid do women need?
Women able to get pregnant need 400 to 800 mcg or micrograms of folic acid every day, even if they are not planning to get pregnant. (This is the same as 0.4 to 0.8 mg or milligrams.) That way, if they do become pregnant, their babies will be less likely to have birth defects. Talk with your doctor about how much folic acid you need if: • You are pregnant or are planning to become pregnant. Pregnant women need 400 to 800 mcg of folic acid in the very early stages of pregnancy often before they know that they are pregnant. A pregnant woman should keep taking folic acid throughout pregnancy. Women should discuss their folic acid needs with their doctors. Some doctors prescribe prenatal vitamins that contain higher amounts of folic acid. • You are breastfeeding. Breastfeeding women need 500 mcg. Some doctors suggest that breastfeeding women keep taking their prenatal vitamins to be sure they are getting plenty of folic acid while they are breastfeeding and should they become pregnant agai
