How can folate (folic acid) prevent birth defects?

Very important: Folate (folic acid) is used by the developing fetus in the formation of the nervous system and spinal cord. If the fetus does not receive enough folate, (folic acid) it is at risk for defects such as spina bifida, or anencephaly (no head).

Help DNA replication: Folic acid is essential for the growth of rapidly dividing cells (a prime example would be fetal cells) as it protects the integrity of genetic information from one cell division to the next. It can prevent 75-95% of all heart and brain defects and may even be able to prevent preterm birth if taken for 3-12 months before conception. All reproductive age women should be taking 1-5 mg daily!
