What Is Folic Acid?

Hits: 6608

Folic acid is a B vitamin. Our bodies use it to make new cells. Getting enough folic acid is especially important during growth spurts and during pregnancy.

Folic acid protects unborn babies against serious birth defects. You can get folic acid from vitamins and fortified foods, such as breads, pastas and cereals. Folate is found naturally in foods such as leafy green vegetables, oranges, and beans.

 

Folic acid is the man-made form of folate, a B vitamin. Folate is found naturally in certain fruits, vegetables, and nuts. Folic acid is found in vitamins and fortified foods.

Folic acid and folate help the body make healthy new red blood cells. Red blood cells carry oxygen to all the parts of your body. If your body does not make enough red blood cells, you can develop anemia. Anemia happens when your blood cannot carry enough oxygen to your body, which makes you pale, tired, or weak. Also, if you do not get enough folic acid, you could develop a type of anemia called folate-deficiency anemia.


 

Why do women need folic acid?

Everyone needs folic acid to be healthy. But it is especially important for women:

How do I get folic acid?

You can get folic acid in two ways.

  1. Through the foods you eat. Folate is found naturally in some foods, including spinach, nuts, and beans. Folic acid is found in fortified foods (called "enriched foods"), such as breads, pastas, and cereals. Look for the term "enriched" on the ingredients list to find out whether the food has added folic acid.
  2. As a vitamin. Most multivitamins sold in the United States contain 400 micrograms, or 100% of the daily value, of folic acid. Check the label to make sure.
  • How much folic acid do women need?
    1. All women need 400 micrograms of folic acid every day. Women who can get pregnant should get 400 to 800 micrograms of folic acid from a vitamin or from food that has added folic acid, such as breakfast cereal.2 This is in addition to the folate you get naturally from food.
    2. Some women may need more folic acid each day. See the chart to find out how much folic acid you need.

    If you:

    Amount of folic acid you may need daily

    Could get pregnant or are pregnant

    400–800 micrograms. Your doctor may prescribe a prenatal vitamin with more.

    Had a baby with a neural tube defect (such as spina bifida(SPEYE-nuh BIF-ih-duh)) and want to get pregnant again

    4,000 micrograms. Your doctor may prescribe this amount. Research shows taking this amount may lower the risk of having another baby with spina bifida.

    Have a family member with spina bifida and could get pregnant

    4,000 micrograms. Your doctor may prescribe this amount.

    Have spina bifida and want to get pregnant

    4,000 micrograms. Your doctor may prescribe this amount. Women with spina bifida have a higher risk of having children with the condition.

    Take medicines to treat epilepsy, type 2 diabetes, rheumatoid arthritis, or lupus

    Talk to your doctor or nurse. Folic acid supplements can interact with these medicines.

    Are on dialysis for kidney disease

    Talk to your doctor or nurse.

    Have a health condition, such as inflammatory bowel disease or celiac disease, that affects how your body absorbs folic acid

    Talk to your doctor or nurse.

  • Are some women at risk for not getting enough folic acid?
  • If you do not get enough folic acid before and during pregnancy, your baby is at higher risk for neural tube defects.

    Neural tube defects are serious birth defects that affect the spine, spinal cord, or brain and may cause death. These include:

    Do I need to take folic acid every day even if I'm not planning to get pregnant?

    Yes. All women who can get pregnant need to take 400 to 800 micrograms of folic acid every day, even if you're not planning to get pregnant. There are several reasons why:

     

    What foods contain folate?

    Folate is found naturally in some foods. Foods that are naturally high in folate include:

    What foods contain folic acid?

    Folic acid is added to foods that are refined or processed (not whole grain):

    Since 1998, the Food and Drug Administration (FDA) has required food manufacturers to add folic acid to processed breads, cereals, flours, cornmeal, pastas, rice, and other grains. For other foods, check the Nutrition Facts label on the package to see if it has folic acid. The label will also tell you how much folic acid is in each serving. Sometimes, the label will say "folate" instead of folic acid.

     


    How can I be sure I get enough folic acid?

    You can get enough folic acid from food alone. Many breakfast cereals have 100% of your recommended daily value (400 micrograms) of folic acid.

    If you are at risk for not getting enough folic acid, your doctor or nurse may recommend that you take a vitamin with folic acid every day. Most U.S. multivitamins have at least 400 micrograms of folic acid. Check the label on the bottle to be sure. You can also take a pill that contains only folic acid.

    If swallowing pills is hard for you, try a chewable or liquid product with folic acid.

    Can I get enough folic acid from food alone?

    Yes, many people get enough folic acid from food alone. Some foods have high amounts of folic acid. For example, many breakfast cereals have 100% of the recommended daily value (400 micrograms) of folic acid in each serving. Check the label to be sure.

    Some women, especially women who could get pregnant, may not get enough folic acid from food. African-American women and Mexican Americans are also at higher risk for not getting enough folic acid each day. Talk to your doctor or nurse about whether you should take a vitamin to get the 400 micrograms of folic acid you need each day.


     

    What is folate-deficiency anemia?

    Folate-deficiency anemia is a type of anemia that happens when you do not get enough folate. Folate-deficiency anemia is most common during pregnancy. Other causes of folate-deficiency anemia include alcoholism and certain medicines to treat seizures, anxiety, or arthritis.

    The symptoms of folate-deficiency anemia include:

    If you have folate-deficiency anemia, your doctor may recommend taking folic acid vitamins and eating more foods with folate.

     


     

    Can I get too much folic acid?

    Yes, you can get too much folic acid, but only from man-made products such as multivitamins and fortified foods, such as breakfast cereals. You can't get too much from foods that naturally contain folate.

    You should not get more than 1,000 micrograms of folic acid a day, unless your doctor prescribes a higher amount. Too much folic acid can hide signs that you lack vitamin B12, which can cause nerve damage.

     

    Do I need folic acid after menopause?

    Yes. Women who have gone through menopause still need 400 micrograms of folic acid every day for good health. Talk to your doctor or nurse about how much folic acid you need.
