Pyridoxamine
Pyridoxamine is a vitamer in the vitamin B6 family, which includes pyridoxal and pyridoxine. Pyridoxamine is converted to the biologically active form of vitamin B6, pyridoxal 5-phosphate, via the vitamin B6 salvage pathway. Vitamin B6 acts as an enzyme cofactor in a variety of metabolic processes. In food, pyridoxamine is commonly found as a 5’-phosphate derivative, which is hydrolyzed by intestinal phosphatases to pyridoxamine and absorbed in the jejunum. Absorbed pyridoxamine is converted to pyridoxamine 5’-phosphate by pyridoxal kinase, which is further converted to the active pyridoxal 5-phosphate by pyridoxamine-phosphate transaminase or pyridoxine 5’-phosphate oxidase.
Pyridoxamine is based on a pyridine ring structure, with hydroxyl, methyl, aminomethyl, and hydroxymethyl substituents. It differs from pyridoxine by the substituent at the 4-position. The phenol at position 3 and aminomethyl group at position 4 of its ring endow pyridoxamine with a variety of chemical properties, including the scavenging of free radical species and carbonyl species formed in sugar and lipid degradation and chelation of metal ions that catalyze Amadori reactions.

Vitamin B6 in trouble: FDA confused about pyridoxamine | The Nutritional and Dietary Supplement Law Blog
Vitamin B6 In a bizarre response to a citizen petition, the FDA has ruled that “Pyridoxamine dihydrochloride or any other compound containing Pyridoxamine” are not dietary supplements within the meaning as indicated by DSHEA, specifically Federal Food, Drug, and Cosmetic (FFDC) Act § 201(ff) and “may not be marketed as such. ” This FDA pronouncement implicates DSHEA directly because it appears that the agency has determined that there is no “independent, verifiable evidence” of marketing of Pyridoxamine as a food or dietary supplement prior to 1994 when DSHEA went into effect.
