The form of folate that is used in food fortification and most dietary supplements is a synthetic form; pteroylmonglutamate. There are important differences between naturally occurring and synthetic forms of folate however, and this article seeks to explain some of those differences.

Folate (vitamin B9) in any form is not used directly within the body, but is metabolised to a metabolically active co-enzyme, tetrahydrafolate (tetrahydrafolic acid).
