One in 1,000 babies is born with neural tube defects (NTDs) such as anencephaly and spina bifida (1). Research notes that the intake of folic acid supplements significantly lowered the risk of NTD affecting the pregnancy.
Folic acid or folate, which is referred to as the ‘pregnancy superhero’, should be consumed by women before and after they get pregnant. In this article, MomJunction tells you all about folic acid during pregnancy: how much you need, how to obtain it (sources) and when to avoid taking it.
What Is Folic Acid?
Folic acid is a synthetic form of vitamin B9 found in fortified foods and other supplements. It is usually utilized by the body to produce new cells and nucleic acid (which is a form of genetic material). It is essential for the healthy growth and development of the baby and helps in carrying out specific functions such as producing red blood cells, protecting the child’s ability to hear and supporting the baby’s organ development (2).
Experts recommend taking 400mcg of folic acid along with prenatal vitamins every day before and during pregnancy (3).
Why Should You Take Folic Acid When Pregnant?
Here is why you need to increase your intake of folic acid if you are pregnant or are trying to get pregnant.
1. Prevents neural tube defects:
Folic acid helps in the neural development of the fetus. The neural tube of your fetus, which later grows into the brain and spinal cord of your baby, is protected by folic acid to prevent any prenatal defects during the early formation of the central nervous system (2).
2. Produces red blood cells:
Folate enhances the production of red blood cells in your body. This is vital during pregnancy when anemia (iron deficiency) is a common complaint. Folic acid ensures that the red blood cell (RBC) count in your body is normal even when you take other supplements that could replenish the iron (4).
3. Protects the baby from several complications:
Folic acid lowers the baby’s risk of cleft lip and palate. It also reduces the risk of premature birth, miscarriage, poor baby growth in your womb and low birth weight problems (2).
4. Protects expectant mom:
Adequate intake of folic acid everyday is known to prevent preeclampsia, heart stroke, heart disease, cancers and Alzheimer’s disease (5).
5. Other essential functions:
Folic acid is required for the production, repair, and f unctioning of DNA. It is also important for the quick growth of the placenta and developing baby (6).
Given its importance, folic acid needs to be taken even before you get pregnant.
