Lauren Manaker, a registered dietitian nutritionist from Charleston, South Carolina, says, “Folic acid isnt classified as a drug. It is a nutrient. People can take this supplement to get B vitamins. However, while it is often thought of as a nutrient that helps reduce the risk of congenital disabilities, once a person becomes pregnant, it may also support fertility. Folic acid can have antioxidant activity which may support egg and/or sperm health.”
