  • Genestra Glutathione Precursors provides antioxidant support and supports glutathione formation. 
  • Glutathione, or glutamyl-cysteinylglycine (GSH), is the primary intracellular antioxidant involved in preventing lipid and protein oxidation and is a critical component in the enzymatic process used to detoxify hydroxide peroxide (H2O2). 
  • Cysteine, glutamic acid and glycine are the three essential precursors for endogenous glutathione production. 
  • Supplementation with NAC, cysteine, and glycine has been shown to increase GSH levels.
