Intestinal absorption of natural folate and folic acid. Legend: (1) food folates are hydrolyzed during digestion to the monoglutamate form; (2) Folic acid must be reduced to tetrahydrofolate in a two-step reaction by DHFR; (3) supplements in the natural form of folate, (6S)-5-methyltetrahydrofolic acid, may enter circulation directly for use in the body as 5-MTHF; and (4) both food folates and folic acid are ultimately metabolized to 5-MTHF by MTHFR
