Folic acid is a synthetic form of folate — a naturally occurring B vitamin.
Your body needs this nutrient to make new cells.
Folic acid is found in supplements and fortified foods, including pasta, bread, rice, and breakfast cereals.
As a medicine, folic acid is used to treat certain types of anemia (a lack of red blood cells) and a folic acid deficiency.
People who need extra folate in their diet also take folic acid supplements. The Centers for Disease Control and Prevention (CDC) recommends that women of reproductive age take folic acid to reduce the risk of birth defects.
Folic acid is available in both an over-the-counter (OTC) and prescription form.
It’s a good idea to talk to your doctor before starting on any new supplement, including folic acid.
