What is riboflavin? Riboflavin, or vitamin B2, is a water-soluble B vitamin that plays a central role in cellular metabolism, mitochondrial function, and redox homeostasis. Biochemically, riboflavin is the precursor for the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), both of which are essential for the activity of a wide range of flavoproteins involved in oxidative metabolism. Riboflavin is absorbed in the proximal small intestine via a saturable carrier-mediated process and is rapidly converted intracellularly to FMN and subsequently to FAD, the latter being the predominant flavin coenzyme in tissues. FMN and FAD serve as obligatory cofactors for enzymes involved in critical metabolic pathways, including the citric acid cycle, β-oxidation of fatty acids, and the electron transport chain. FAD is a key component
