Folic acid is a B vitamin. It helps the body make healthy new cells, meaning it is important for cell growth and metabolism. “Folic acid” and “folate” mean the same thing. They have the same effects. Folic acid is a man-made form of folate and is in supplements and added to foods. Folate is found naturally in certain foods. Studies show that many people in the U.S. don’t get enough folic acid in their diets.
Why do people take Folate and Folic Acid?
All people need folic acid. Folic acid supplements are standard for pregnant women and women who plan to become pregnant. Folic acid reduces the risk for birth defects of a baby’s brain and spine — spina bifida and anencephaly (which is when most or all of the brain does not develop; Babies with this problem die before or shortly after birth). Folic acid may also lower the risk of preeclampsia and early labor. Many doctors recommend that any woman of childbearing age take either a multivitamin or a folic acid supplement. Folic acid can protect against birth defects that may form before a woman knows she is even pregnant.
Folic acid is used to treat deficiencies, which can cause certain types of anemia and other problems. Folate deficiencies are more common in people who have digestive problems, kidney or liver disease, or who abuse alcohol. Folic acid supplements have been studied as treatments for many other conditions like heart health and preventing cell changes that may lead to cancer however, the results of these studies have been inconclusive.
