Prevents neural tube defects
Neural tube defects (NTDs) are serious birth defects that affect the brain, spine, and spinal cord. They occur when the neural tube, which is the embryonic structure that forms these organs, fails to close properly during pregnancy.
NTDs can range in severity from mild to severe. Some common types of NTDs include spina bifida, anencephaly, and encephalocele. Spina bifida is the most common NTD, and it occurs when the neural tube fails to close in the lower back, causing a gap in the spinal cord. Anencephaly is a fatal condition in which the brain and skull are missing. Encephalocele is a condition in which a sac containing brain tissue protrudes from the skull.
Folic acid is essential for preventing NTDs. Studies have shown that women who take 400 micrograms (mcg) of folic acid daily before and during early pregnancy can reduce their risk of having a baby with an NTD by up to 70%. Folic acid works by helping to produce DNA, which is essential for the proper development of the neural tube.
All women who are capable of becoming pregnant should take 400 mcg of folic acid daily, even if they are not planning to conceive immediately. This is because NTDs can occur very early in pregnancy, even before a woman knows she is pregnant.
By taking folic acid supplements or consuming foods rich in folic acid, women can help to protect their unborn babies from NTDs and ensure their healthy development.
