What you need to know: Folic acid, a B vitamin, helps prevent birth defects of the brain and spinal cord when taken before getting pregnant and during early pregnancy. It is available in most multivitamins, as a folic acid-only supplement and in some foods. Folate is the natural form of folic acid that is found in certain foods.
What you can do: Take a multivitamin with at least 400 micrograms of folic acid every day before pregnancy as part of a healthy diet. During pregnancy, switch to a prenatal vitamin, which should have 600 micrograms of folic acid.
Eat a healthy diet that includes foods that contain folate, the natural form of the vitamin. Such foods include fortified breakfast cereals, dried beans, leafy green vegetables and orange juice.
If you have already had a pregnancy affected by a birth defect of the brain or spinal cord, ask your health care provider how much folic acid you need. Studies have shown that taking a larger dose of folic acid daily can reduce the risk of having another affected pregnancy. The larger dose needs to be taken at least 1 month before pregnancy and in the first trimester of pregnancy. The recommended dose in this case is 4 milligrams (4,000 micrograms).
Take Folic Acid Before You're Pregnant
Folic acid is a naturally occurring B vitamin. It helps a fetus's neural tube develop properly. The neural tube is the part of a developing baby that becomes the brain and spinal cord. When the neural tube does not close properly, a baby is born with a very serious birth defect called a neural tube defect (NTD).
The good news is that folic acid can help prevent neural tube defects. However, folic acid only works if taken before getting pregnant and during the first few weeks of pregnancy, often before a woman may even know she is pregnant. Since nearly half of all pregnancies in the U.S. are unplanned, it's important that all women of childbearing age (even if they're not trying to get pregnant) get the recommended daily amount of folic acid.
The best way to get enough folic acid is to take a multivitamin with at least 400 micrograms of folic acid in it and eat a healthy diet. Most multivitamins have this amount, but check the label to be sure. You also can get folate (the natural form of folic acid) in your diet, but most women don't get the recommended amount of folate or folic acid from diet alone.
About 3,000 pregnancies are affected by neural tube defects each year in the United States. If all women took adequate folic acid before getting pregnant and during early pregnancy, up to 70 percent of neural tube defects could be prevented.
Once you're pregnant, you should increase your folic acid intake to at least 600 micrograms of folic acid. Your prenatal vitamin should have the right amount of folic acid you'll need during pregnancy.
Most women should limit the amount of folic acid they take to 1,000 micrograms a day unless otherwise directed by a health provider. For example, women who have had a previous pregnancy affected by birth defects of the brain and spine and women with sickle cell disease should be sure to talk with their health providers about the need for more folic acid.
Folic Acid in Foods Folic acid is found in the following foods:
Fortified breakfast cereals (look on the label to see if the cereal has been fortified with folic acid)
Folic Acid Is Good for Mom and Dad, Too Folic acid is important for everyone in maintaining health. It plays an important role in the production of red blood cells. Folic acid may also help prevent certain health problems; research is still being done.
