Even if you watch your diet, it can be difficult to get the amount of folic acid you need from food alone. This is especially important for women.
Taking a daily vitamin can help. Most multivitamins contain the recommended amount of folic acid. If you're not sure which vitamin to take, read the label. It should say that the vitamin contains 400 mcg or 100% of the daily recommended value of folic acid.
If you're trying to get pregnant or are already pregnant, your doctor may prescribe a prenatal vitamin, which will contain all the folic acid you'll need (unless you've already had a baby with a neural tube defect, in which case your doctor will prescribe a much higher dose of folic acid).
