Recancostat is a patented combination of reduced glutathione (GSH), anthocyanins, and l-cysteine. This oral supplement has been clinically studied for support of healthy cell development.  The key ingredient in Recancostat is GSH. Reduced GSH is naturally occurring in the body and is present in every type of cell. It is essential to cellular detoxification, amino acid transport, production of coenzymes and recycling of vitamins E and C.  A powerful antioxidant that functions inside the cells, reduced glutathione blocks free radical damage to all types of tissues.
