L-Glutathione participates in numerous cell functions including the synthesis of proteins, regulation of enzyme activity, amino acid transport and catabolism of reactive oxygen species. Glutathione is the most powerful antioxidant available in the liver for detoxifying free radicals and is critical for overall health maintenance. Glutathione is known as the "triple threat" amino acid and is found in the cells of nearly all living organisms on earth; its primary job is waste disposal.
