Riboflavin, also known as vitamin B2, is a vitamin found in food and used as a dietary supplement.[1][3] Food sources include eggs, green vegetables, milk and other dairy product, meat, mushrooms, and almonds.[3] Some countries require its addition to grains.[3][4] As a supplement it is used to prevent and treat riboflavin deficiency and prevent migraines.[1][3] It may be given by mouth or injection.[1]It is nearly always well tolerated.[1] Normal doses are safe during pregnancy.[1] Riboflavin is in the vitamin B group.[1] It is required by the body for cellular respiration.[1]Riboflavin was discovered in 1920, isolated in 1933, and first made in 1935.[5] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[6] Riboflavin is available as a generic medication and over the counter.[7] In the United States a month of supplements costs less than 25 USDFlavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) function as cofactors for a variety of flavoprotein enzyme reactions:Flavoproteins of electron transport chain, including FMN in Complex I and FAD in Complex IIFAD is required for the production of pyridoxic acid from pyridoxal (vitamin B6) by pyridoxine 5'-phosphate oxidaseThe primary coenzyme form of vitamin B6 (pyridoxal phosphate) is FMN dependentOxidation of pyruvate, α-ketoglutarate, and branched-chain amino acids requires FAD in the shared E3 portion of their respective dehydrogenase complexesFatty acyl CoA dehydrogenase requires FAD in fatty acid oxidationFAD is required to convert retinol (vitamin A) to retinoic acid via cytosolic retinal dehydrogenaseSynthesis of an active form of folate (5-methyltetrahydrofolate) from 5,10-methylenetetrahydrofolate by Methylenetetrahydrofolate reductase is FADH2 dependentFAD is required to convert tryptophan to niacin (vitamin B3)Reduction of the oxidized form of glutathione (GSSG) to its reduced form (GSH) by Glutathione reductase is FAD dependentFor the molecular mechanism of action see main articles Flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD)Other Flavin derivatives such as N(5)-ethylflavinium ion, Et-Fl+, can oxidize water and produce O2.[Provides energy production for healthy nerve function and cell formation.
