Glutathione Plus 60 Caps

Body cells and tissues are threatened continuously bydamage caused by toxic free radicals and reactive oxygenspecies (e.g., peroxides) which are produced during normaloxygen metabolism, by other chemical reactions, and bytoxic agents in the environment. Free radicals are capable ofdisrupting metabolic activity and cell structure. When thisoccurs, additional free radicals are produced which, in turn,can result in more extensive damage to cells and tissues.The uncontrolled production of free radicals is thought to bea major contributing factor to many degenerative diseases.Glutathione is a naturally-occurring tripeptide of L-cysteine,L-glutamate and L-glycine. Glutathione is the essentialcosubstrate for two major antioxidant enzymes in the body;glutathione peroxidase and glutathione reductase. As such,glutathione offers one mechanism for scavenging toxic freeradicals. Glutathione is well absorbed in the intestine, andenters the blood and other extracellular compartments whereit exerts much of its beneficial antioxidant effects. However,it can not effectively enter the cell.N-Acetylcysteine (NAC) is a precursor for the sulfur aminoacid cysteine, and cysteine is used by the body to synthesizeglutathione.In contrast to glutathione, NAC is efficiently transported intothe cell where it is readily converted to L-cysteine forglutathione synthesis. NAC is well absorbed, and unlikeL-cysteine, is virtually non-toxic. NAC is recognized as asafe, highly effective means of increasing intracellularglutathione stores. Aside from providing cysteine as aglutathione precursor, NAC also appears to have antioxidantproperties by itself, and is a valuable sulfur donor for variousmetabolic needs.Glutathione Plus™ combines significant levels ofglutathione with N-acetylcysteine, thus providing a means ofraising both extracellular and intracellular glutathione levels.
