Folic acid (Vitamin B9) is a B-vitamin that is necessary for the normal function of red and white blood cells. Vitamin B9, also called folate or folic acid, is one of 8 B vitamins. Folic acid is the synthetic form of B9, found in supplements and fortified foods, while folate occurs naturally in foods. Folic acid can be found in green leafy vegetables.
Folic acid is crucial for proper brain function and plays an important role in mental and emotional health. It aids in the production of DNA and RNA, the body’s genetic material, and is especially important when cells and tissues are growing rapidly, such as in infancy, adolescence, and pregnancy. Folic acid also works closely with vitamin B12 to help make red blood cells and help iron work properly in the body.
