Riboflavin-5'-phosphate sodium salt dihydrateProduct ingredient for Flavin mononucleotide
- Name
- Riboflavin-5'-phosphate sodium salt dihydrate
- Drug Entry
- Flavin mononucleotide
Flavin mononucleotide (FMN), also known as riboflavin 5'-phosphate, is one of the two major coenzymes derived from riboflavin (vitamin B2) and is one of the principal forms in which dietary riboflavin is found.1,3 FMN is composed of an isoalloxazine ring - which serves as the active redox center - attached to a ribityl phosphate chain.4 Alongside flavin adenine dinucleotide (FAD), for which it is a direct precursor, FMN plays critical roles in energy production, cellular function, and in the metabolism of fats, drugs, and steroids.3
In addition to its systemic use as a means of riboflavin supplementation, a topical ophthalmic preparation of FMN was approved by the FDA in October 2025 for use as a photoenhancer in epithelium-on corneal collagen cross-linking.5,2
