Mechanism of action

Riboflavin (vitamin B2) is an essential micronutrient that serves as a precursor for flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), which are critical cofactors for numerous oxidoreductase enzymes. The sodium phosphate salt form enhances bioavailability and allows for parenteral administration. It supports mitochondrial function, antioxidant defense systems, and energy production through the electron transport chain.
