Source Naturals Coenzymated B-2 25mg - Quick Dissolve Vitamin - 30 Lozenges

In order for vitamins to be utilized by the body, they must first be converted into their active coenzyme forms. Coenzymated B-2 sublingual goes directly into the bloodstream in its active form, ready to go to work immediately. This avoids the loss that may occur not only during digestion, but during the liver's conversion process as well. Flavin mononucleotide (FMN), also called riboflavin phosphate, is one of the two metabolically active coenzyme forms of vitamin B-2. FMN is itself the precursor for the other B-2 coenzyme, FAD. FMN is involved in a wide array of enzymes and has many roles in energy production from our food, as well as bio-converting B-6 to its coenzyme form.
