Medical experts suggest that women at child bearing age must take 400mcg of folic acid daily. This means folic acid before conceiving is also crucial and must be in daily diet. The US National Health institute, the American College of Obstetricians and Gynecologists, and the Center of Disease Control and Prevention recommends usage of folic acid during pregnancy. The reason is that folic acid pregnancy helps in prevention from the neural tube defects. Spina biida and anencephaly are two of the common defects of the category.
