Folic acid is a crucial prenatal vitamin for preventing neural tube defects. Neural tube defects, such as spina bifida and anencephaly, occur when the neural tube, which develops into the baby's spine and brain, does not close properly during the early weeks of pregnancy. Adequate folic acid intake before conception and during the first trimester significantly reduces the risk of these defects.

Healthcare providers often recommend that women of childbearing age take a daily supplement containing folic acid, typically at a dosage of 400 to 800 micrograms, to ensure sufficient levels are present during the critical early stages of fetal development. Folic acid plays a vital role in DNA synthesis and cell division, making it essential for the growth and development of the embryo.
