Higher Absorption Rate Liposomal Glutathione Supplement Capsules Glutathione Powder En Poudre

Liposomal glutathione is a delivery form in which glutathione (GSH), a tripeptide antioxidant, is encapsulated within phospholipid bilayer vesicles. Its primary purpose is to address the fundamental limitation of conventional oral glutathione: negligible systemic bioavailability due to rapid enzymatic degradation in the gastrointestinal tract and poor cellular uptake.

Mechanism and Advantages of  Liposomal Glutathione 

Protection from Digestion: The human gastrointestinal tract contains substantial γ-glutamyltransferase activity, which hydrolyzes glutathione into its constituent amino acids before intact absorption can occur. The liposomal shell shields GSH from this enzymatic breakdown, allowing more of the intact tripeptide to reach systemic circulation.

Enhanced Cellular Delivery: Liposomes can fuse with cell membranes or be taken up via endocytosis, delivering intact GSH directly to the cytosol and bypassing metabolic bottlenecks. This is particularly relevant because glutathione functions intracellularly.

Stability: Encapsulation protects glutathione from oxidative degradation during storage and transit through the digestive system. Commercial formulations often include phospholipids from sunflower or soy lecithin as the vesicle-forming material.
