Folic acid deficiency is most commonly associated with neural tube defects (NTDs) during pregnancy. Neural tube defects, which include conditions such as spina bifida and anencephaly, occur when the neural tube does not close properly during the early stages of fetal development. Folic acid, a B vitamin, is essential for proper cell division and the synthesis of DNA, particularly during periods of rapid growth and development like those seen in early pregnancy.

Research has shown that adequate intake of folic acid before conception and during early pregnancy significantly reduces the risk of these defects. The recommendation for women of childbearing age is to take a daily supplement of folic acid to help ensure they have sufficient levels before and during early pregnancy.

In contrast, while other nutrients such as iron, vitamin B12, and vitamin D are important for overall health and play vital roles in various physiological processes, they have not been specifically linked to neural tube defects as compellingly as folic acid has. Iron is crucial for preventing anemia, vitamin B12 is essential for nerve health and red blood cell formation, and vitamin D is important for bone health and immune function but does not have the same direct correlation with the prevention of neural tube defects.
