Others antioxidants - Glutathione (GSH)

Glutathione (GSH), a polypeptide of glycine, cysteine, and glutamic acid that occurs widely in plant and animal tissues beside is best known for its role in enhancing the immune system in protect our body from bacteria and virus, it also is an antioxidant that helps to prevent damage caused by oxidation of cellular components such as free radicals and peroxides by converting to its oxidized form glutathione disulfide (GSSG), leading to generation of antioxidant enzymes, glutathione peroxidases and peroxiredoxins of which reduces the risk of oxidative DNA damage and subsequently the individual’s risk of cancer susceptibility. Deficiency of Glutathione (GSH) causes hemolytic anemia, progressive degeneration of the spinal cord, disorders of the peripheral nervous system, diseases of the skeletal muscles,, etc. Intake with vitamin D increases glutathione levels in the brain and appears to be a catalyst for glutathione production.
