What is the recommended dietary supplement for women of childbearing age to prevent neural tube defects?

Folic acid is the recommended dietary supplement for women of childbearing age to prevent neural tube defects. Neural tube defects, such as spina bifida and anencephaly, are serious congenital malformations that occur in the early stages of pregnancy, often before a woman knows she is pregnant. Adequate folate, a B vitamin, is crucial because it helps in the proper formation of the neural tube during fetal development.

Research has shown that women who consume enough folic acid around the time of conception and in the first trimester can significantly reduce the risk of these defects. Health organizations, including the Centers for Disease Control and Prevention (CDC), recommend that women of childbearing age take a daily supplement containing 400 micrograms of folic acid, in addition to obtaining folate from food sources. This proactive approach helps ensure that women have sufficient levels of this critical nutrient at the point of conception.

While iron, vitamin D, and calcium are important nutrients for overall health, they do not have the specific role in preventing neural tube defects that folic acid does. Iron is essential for preventing anemia, vitamin D plays a role in bone health and immune function, and calcium is crucial for bone development, but none of them have the same established relationship
