Supplement Sensation? Oral Glutathione Supplements Dose-Dependently Double GSH in Randomized Controlled Human Studies. Health Implications Still to Be Determined

If you have been interested in dietary supplements for some time, I am pretty sure that you will have heard about oral glutathione ob(GSH) supplements in one of the "snake oil warnings" on various websites. The "master antioxidant" as it is called is after all believed by many to be not bioavailable - at least not orally. Studies in animal models, however, have already shown that oral GSH, administered either in the diet or by gavage, has the ability to increase plasma and tissue GSH levels ( Loven. 1986; Aw. 1991; Favilli. 1997; Kariya. 2007).
