Codeage Liposomal Glutathione delivers Setria® L-Glutathione Reduced — the only patented, clinically studied form of L-Glutathione with human clinical trial evidence for its ability to raise whole blood and red blood cell glutathione levels with oral supplementation — in a liposomal phospholipid delivery system that further enhances absorption by protecting glutathione from degradation in the GI tract.Glutathione is the body's master antioxidant — a tripeptide (L-Glutamate + L-Cysteine + Glycine) synthesized in every cell that is responsible for neutralizing reactive oxygen species, recycling vitamins C and E, conjugating and neutralizing toxic compounds in the liver, supporting the immune system's natural killer cell activity, and maintaining the intracellular redox balance that underlies cellular health. Standard oral glutathione historically had poor bioavailability; Setria® L-Glutathione Reduced is specifically the form shown in double-blind clinical studies to increase blood glutathione levels. Liposomal phospholipid encapsulation provides additional protection during GI transit. Vegan, non-GMO. Available at Beauty Riche with same-day shipping.
