Yibu Selenium is a small molecule antioxidant that is easy to participate in various redox reactions. It can clear excessive peroxides in the body, block the chain reaction that produces free radicals, and therefore can treat various diseases and maintain normal physiological functions of the body. For a long time, it has been widely believed in the human Chemicalbook that ibuprofen mainly functions in the body by simulating the reaction mechanism of glutathione peroxidase. However, recent studies have shown that Ibselenide tends to exert its effects in the body through the thioredoxin reductase and thioredoxin reaction system.
