Folic Acid Vital Before and During Pregnancy to Reduce Risk of Small Gestational Age.
Women who take folic acid prior to conception appear to be less likely to have babies that are small for their gestational age, which can cause an array of health complications. Folic acid is a B vitamin that is already highly recommended for women of a childbearing age, as it reduces the risk of a child developing neural tube defects, such as spina bifida. The study found that the highest rates of small gestational age occurred among babies whose mothers had not taken folic acid before conception or during pregnancy.
