CDC urges all women of reproductive age to take 400 micrograms (mcg) of folic acid each day, in addition to consuming food with folate from a varied diet, to help prevent some major birth defects of the baby’s brain (anencephaly) and spine (spina bifida).

 

About folic acid

Folic acid is a B vitamin. Our bodies use it to make new cells. Think about the skin, hair, and nails. These–and other parts of the body – make new cells each day. Folic acid is the synthetic (that is, not generally occurring naturally) form of folate used in supplements and in fortified foods such as rice, pasta, bread, and some breakfast cereals

 

Why folic acid is important before and during pregnancy

When the baby is developing early during pregnancy, folic acid helps form the neural tube. Folic acid is very important because it can help prevent some major birth defects of the baby’s brain (anencephaly) and spine (spina bifida). The neural tube forms the early brain and spine.

 

Women of reproductive age need 400 mcg of folic acid every day

  • All women of reproductive age should get 400 mcg of folic acid every day to get enough folic acid to help prevent some birth defects because
    • About half of U.S. pregnancies are unplanned, and
    • Major birth defects of the baby’s brain or spine occur very early in pregnancy (3-4 weeks after conception), before most women know they are pregnant.
  • When taking folic acid, a higher dose than 400 mcg of folic acid each day is not necessarily better to prevent neural tube defects, unless a doctor recommends taking more due to other health conditions.
    • When planning to become pregnant, women who have already had a pregnancy affected by a neural tube defect should consult with their healthcare provider. CDC recommends that these women consume 4,000 mcg of folic acid each day one month before becoming pregnant and through the first 3 months of pregnancy.
