Glutathione is a tripeptide containing glutamic acid, cysteine & glycine. Since it can be formed from these three amino acids in the body, it is deemed non-essential, in that is does not have to be obtained from food. As cysteine is relatively rare in foodstuffs, it is this amino acid that is the rate-limiting factor in glutathione synthesis by the body. Glutathione is found in all cells in the body, with the highest concentration being found in the liver, making it critically important in the detoxification & elimination of free radicals. It forms the enzyme glutathione peroxidise which is one of the bodys most powerful antioxidants. Metabolically, glutathione has numerous functions. It plays a substantial role in the functioning of the bodys immune system. & its antioxidant property makes it vital to white blood cells. It even helps keep antioxidants such as the vitamins C & E in their active forms.
