Folate is a B vitamin. The natural source of folate is green leafy vegetables. Folate supplements are usually in the biologically inactive form folic acid, or vitamin B9. Less common forms of supplementation are l-methylfolate and folinic acid.
Folate is involved in a wide variety of biological functions, and many genes use folate or convert the various forms of folate. Folate deficiency can cause birth defects, so it is commonly used as a supplement during pregnancy. Wikipedia
