Start taking 0.4 mg of folic acid every day when you begin trying to get pregnant, and keep taking it until the end of the first 3 months of pregnancy
Taking one folic acid tablet a day from before pregnancy through early pregnancy cuts the chance of a neural tube defect in the baby by about 70%. Neural tube defects are birth defects such as anencephaly and spina bifida. For someone who has already had one baby with such a defect, the chance of another affected baby falls to about one third of what it was.
