Eto ti malko info, no e na anglijski. Prosto izbrah edno ot mnogoto objasnenija, zastoto mi se stori mnogo jasno i dostxpno za vseki.

What Is Folic Acid?
Folic acid, sometimes called folate, is a B vitamin (B9) found mostly in leafy green vegetables like kale and spinach, orange juice, and enriched grains. Repeated studies have shown that women who get 400 micrograms (0.4 milligrams) daily prior to conception and during early pregnancy reduce the risk that their baby will be born with a serious neural tube defect (a birth defect involving incomplete development of the brain and spinal cord) by up to 70%.

The most common neural tube defects are spina bifida (an incomplete closure of the spinal cord and spinal column), anencephaly (severe underdevelopment of the brain), and encephalocele (when brain tissue protrudes out to the skin from an abnormal opening in the skull). All of these defects occur during the first 28 days of pregnancy - usually before a woman even knows she's pregnant.

That's why it's so important for all women of childbearing age to consume folic acid - not just those who are planning to become pregnant. Only 50% of pregnancies are planned, so any woman who could become pregnant should make sure she's getting enough folic acid.

Doctors and scientists are still not completely sure why folic acid has such a profound effect on the prevention of neural tube defects, but they do know that this vitamin is crucial in the development of DNA. As a result, folic acid plays a large role in cell growth and development as well as tissue formation.
