Dietary SupplementFMN (Flavin Mononucleotide) The Benefits of COENZYMATED™ Vitamins In order for vitamins to be utilized by the body, they must first be converted into their active coenzyme forms. COENZYMATED™ B-2 is ready to go to work immediately. Flavin mononucleotide (FMN), also called riboflavin phosphate, is one of the two metabolically active coenzyme forms of vitamin B-2.
