IVF treatment often requires medication that encourages the body to produce more eggs. Additionally, women undergoing fertility treatment are strongly encouraged to take a prenatal vitamin as they undergo treatment. Prenatal vitamins are created to provide a pregnant woman with the additional vitamins and minerals her body needs during pregnancy. Among these are a folic acid supplement. Folic acid is essential during early pregnancy in order to avoid certain birth defects. Additionally, research is increasingly showing that folic acid supplements may increase success rates during IVF treatment.
