There is no guarantee that folic acid supplementation will prevent neural tube defects, though it has been proven to reduce the risk.

In a woman who has no family history of neural tube defects, it is suggested that she take 0.4 mg of folic acid each day, while a woman with a family history is asked to take 4 mg of folic acid each day (10 times the amount).

Ideally the women would begin taking folic acid at least 3 months before conception, and continue it through at least the end of the first trimester.
