Riboflavin phosphate sodium (FMN) is the sodium phosphate form of riboflavin, a water-soluble and essential micronutrient that is the primary growth promoter of the naturally occurring vitamin B complex. Riboflavin phosphate sodium is converted into 2 coenzymes, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which produce energy by aiding in the metabolism of fats, carbohydrates, and proteins, and are required for red blood cell formation and respiration, antibody production, and regulation of growth and reproduction in the body.

Roseoflavin, a chemical analog of FMN and riboflavin that has antimicrobial activity, can directly bind to FMN riboswitch aptamers and downregulate the expression of an FMN riboswitch-lacZ reporter gene in B. subtilis.
