If you are referring to pteroylglutamic acid, it is a member of the B vitamin complex, sometimes referred to as Vitamin B-9 or folic acid. It acts as a coenzyme (with vitamin B-12 and vitamin C) in the breakdown (metabolism) of proteins and in the synthesis of new proteins. It is necessary for the production of red blood cells and the synthesis of DNA (which controls heredity), as well as tissue growth and cell function. It also increases the appetite and stimulates the formation of digestive acids. By preventing damage to cellular DNA, folic acid may reduce the risk of colon polyps, colorectal cancer and cervical cancer. During pregnancy, folic acid can be vital to healthy fetal growth. British health researchers have expressed concern that deficiencies in vitamin B-12 (cobalamin), which would lead to pernicious anemia, can be masked by significant intake of folic acid, especially in elderly people, such that B-12 supplementation may also be advisable if supplemental folic acid is being ingested. Folic acid is generally considered safe; no upper limit for intake has been established. Folic acid occurs naturally in many types of foods, particularly: liver yeast green leafy vegetables legumes orange juice oranges cereals breads wheat germ To learn more, see this article from the American Journal of Clinical Nutrition.
