Folic Acid (Vitamin B9), A Simple Guide To The Vitamin, Functions And Deficiency

Vitamin B9 (folic acid) is present in all living human tissues as important enzymes in amino acid and carbohydrate metabolism and red blood cells production.

All B vitamins help the body convert food (carbohydrates) into fuel (glucose) which is used to produce energy. B complex vitamins are needed for healthy skin, hair, eyes and liver.
They also help the nervous system function properly. Folic acid is found primarily in:1. Animal sources - liver, kidneys, salmon, milk2. Vegetable sources: dark green leafy vegetables and yeastFolic acid is essential for production of red blood cells. Folic acid also works closely with vitamin B12 to help make red blood cells and help iron work properly in the body.

Vitamin B9 works with vitamins B6 and B12 and other nutrients to control blood levels of the amino acid homocysteine.
Pregnant women need more folic acid to lower the risk of neural tube birth defects including cleft palate, spina bifida, and brain damage.
