What if I didn't take folic acid before pregnancy?

If you don't take folic acid before getting pregnant (conception), it doesn't necessarily mean that your baby will be born with birth defects. However, it's true that folic acid does help to prevent certain birth defects. But it only works if it's taken before getting pregnant and at the beginning of the pregnancy, often before a woman may even know she's pregnant.

Since nearly half of all pregnancies in the United States are unplanned, it's important that all women of childbearing age (even if they're not trying to get pregnant) get at least 400 micrograms of folic acid every day.  Take a multivitamin with folic acid before pregnancy. During pregnancy, switch to a prenatal vitamin, which should have 600 micrograms of folic acid.

What's the best way to get the right amount of folic acid?

Before pregnancy, take a multivitamin that contains 400 micrograms (mcg) of folic acid every day. This is the amount you need to help prevent some birth defects of the brain and spine. During pregnancy, you need at least 600 mcg of folic acid very day. Your prenatal vitamin should have this amount. Talk to your provider about taking a prenatal vitamin.

Can I get folic acid from food?

Yes, but it's sometimes hard to get enough folic acid each day just from food. Foods that contain folate (the natural form of folic acid) include lentils, spinach, black beans, peanuts, orange juice, romaine lettuce and broccoli. You have to eat a lot of these foods to get the right amount of folic acid. Fortified grains, like bread, pasta and breakfast cereal, have more folic acid. "Fortified" means that folic acid has been added to the food. Check the product label to see how much folic acid each serving contains. The simplest way to get enough folic acid every day is to take a multivitamin or a prenatal vitamin. If you're not pregnant yet, take a multivitamin with 400 micrograms (mcg) of folic acid in it each day. If you’re pregnant, take a prenatal vitamin with at least 600 mcg of folic acid in it each day.
