Folic acid is a type of B vitamin, specifically known as vitamin B9. It plays a crucial role in the body by helping to produce and maintain new cells, making it especially important during periods of rapid growth, such as during pregnancy. Folic acid is essential for the formation of DNA and RNA, which are vital for cell division and overall health. This vitamin can be found in various foods, including leafy green vegetables, fruits, beans, and fortified cereals. Many health professionals recommend that women who are pregnant or planning to become pregnant take folic acid supplements to reduce the risk of neural tube defects in the developing fetus.
