This enzyme requires the FAD coenzyme form of riboflavin for this reduction reaction, thus, emphasizing the role of riboflavin in the formation of reduced, active, glutathione ( Second, it has been shown that the oxidation of dihydroriboflavin, the reduced riboflavin, forming oxidized riboflavin can deactivate lipid peroxides, emphasizing the independent antioxidant property of riboflavin ( Third, riboflavin effects on antioxidant enzymes activities, including superoxide dismutase (SOD) ( Important to note, UV-B irradiation, the atmospherically predominant UV radiation, has been shown to reduce the neuroprotective effects of riboflavin both in vitro and in vivo
