Why is folic acid important during pregnancy? (click to expand) »

Folic acid helps build healthy blood and tissues for you and your baby during pregnancy. It’s very important because it helps your baby’s spine, brain and skull develop properly and helps create new red blood cells for both of you. Folic acid can help prevent neural tube defects such as spina bifida in babies before they are born.

Folic acid is most important to a baby’s development in the early weeks of pregnancy, even before most people know they are pregnant. Even if you are not planning to become pregnant, you need to take folic acid because many pregnancies are unplanned.

Eating well during pregnancy is important, but you will not get enough folic acid to protect against neural tube defects with food alone. You still need to take a multivitamin with folic acid every day.

It is hard to get the amount of folic acid you need from food alone. To get enough folic acid:

Some people may need more than 0.4 mg of folic acid daily. This can include people with:

  • previous pregnancy affected with a neural tube defect
  • family history of neural tube defect
  • diabetes (type 1 or 2)
  • celiac disease
  • liver disease
  • kidney dialysis
  • inflammatory bowel disease
  • gastric bypass surgery
  • alcohol overuse
  • antiepileptic or other folate inhibiting drugs

Talk to your health care provider to see if you need a higher amount of folic acid. You should not take more than 1 mg of folic acid per day unless your doctor tells you to.

Read the label to find out the daily dose for your multivitamin. Taking more than the daily dose can cause health risks. Talk to a pharmacist if you have questions.
