Glutathione: The Master AntioxidantGlutathione, a super antioxidant containing the amino acid cysteine, is needed for cellular protection, proper mitochondrial function, and proper immune function. It eliminates "free radicals" that oxidize our living cells and cause aging, cancer, diabetes and many other diseases.Glutathione cannot be swallowed and absorbed into the body, instead it must be produced by the body. It is a powerful antioxidant and increases the effectiveness of our body's other antioxidants. It is also responsible for ushering many toxic compounds from the body.So without glutathione, many of the toxins simply will not leave.
