Glutathione Plays a Huge Role in Mercury Detoxification   Best 3 Chelators Glutathione is an important antioxidant amino acid which protects against mercury toxicity. Glutathione is a tripeptide, made from the combination of three amino acids. L-glycine, L-glutaniic acid, and L-cysteine. Studies have shown that GSH levels are decreased during cases of mercurity toxicity. It is interesting to note that GSH deficiency resulting from genetic errors mimic the acute mercury toxicity effects of Minamata disease. Without enough OSH, mercury from the environment cannot be detoxified and removed.
