CDC urges women to take 400 mcg of folic acid every day, starting at least one month before getting pregnant, to help prevent major birth defects of the baby’s brain and spine. Folic acid is a B vitamin. Our bodies use it to make new cells. Everyone needs folic acid. Folic acid is very important because it can help prevent major birth defects of the baby’s brain and spine (anencephaly and spina bifida) by 50% to 70%. CS212882-A
