The Importance Of Folic Acid In Your Diet Before And During Pregnancy

Folic acid is a B-complex vitamin supplement that helps our bodies to break down important amino and nucleic acids that help keep us healthy. It is in some of the foods that we eat, but our bodies do not absorb much of it; therefore, it is important to take a vitamin supplement that contains folic acid.

The most important times to make sure that you are getting enough folic acid is before you become pregnant and in your first month of pregnancy. Many pregnancies are not planned, so if you are of childbearing age, you should consume .4 milligrams (mg) of folic acid every day. Although some foods are fortified with folic acid, it still unclear how much folic acid the body absorbs from our diet alone.

Lack of folic acid can lead to neural tube defects

When folic acid is taken both before and during pregnancy to help protect your baby from developing a neural tube defect. Neural tube defects affect your baby's nervous system while it is developing, which means a defect would develop during your first month of pregnancy. The most well-known defects are spina bifida and anencephaly. Spina bifida usually leads to paralysis, whereas anencephaly – a condition where most of the brain fails to develop – almost always leads to stillbirth or the death of the baby shortly afterward.

Other types of neural tube defects include:

  • Chiari malformation, a condition where the brain tissues extend into the baby's spinal canal
  • Encephaloceles or protrusions of the brain through the skull
  • Hydranencephaly, where part of the cerebral hemisphere fails to develop
  • Iniencephaly, a condition that causes severe cervical bending, resulting in a child with no neck

Getting enough folic acid can prevent almost all of these defects. It also helps prevent cleft lips and cleft palates, as well as some heart defects.1

If you were born with a neural tube defect, or if one of your children was born with a neural tube defect, or, if you are a type 1 diabetic, you physician or midwife may encourage you to take a vitamin or supplement that contains a specific amount of folic acid each day, starting three months before you become pregnant, and keep taking it during the first 12 weeks of your pregnancy. The United States Preventive Services Task Force recommends that, if it is possible for you to become pregnant, or if you are planning on becoming pregnant, you should take a vitamin, or supplement, that contains .4 to .8 milligrams (mg) of folic acid each day.1
