What is the role of folic acid in preconception health?

Folic acid plays a critical role in preconception health primarily due to its function in preventing neural tube defects. Neural tube defects, which affect the brain and spine, can occur in the early stages of pregnancy, often before a woman even realizes she is pregnant. Adequate levels of folic acid before conception and during the first trimester are essential because this vitamin is involved in DNA synthesis and cell division.

By ensuring that women have enough folic acid in their systems before and during early pregnancy, the risk of developing these serious developmental disorders can be significantly reduced. The Centers for Disease Control and Prevention (CDC) recommends that all women of childbearing age take a daily supplement of folic acid to ensure their bodies have optimal levels to support healthy fetal development.

The other options do not reflect the primary benefits of folic acid in this context. For instance, while folic acid is critical for a healthy pregnancy, it is not directly linked to maternal mood or morning sickness. Additionally, while fetal weight can be influenced by various factors including maternal nutrition, folic acid does not specifically play a role in increasing fetal weight.
