Glutathione: A Comprehensive Review from Raw Material to Application
Reduced glutathione (GSH) is an endogenous core tripeptide active substance in the human body, possessing multiple biological activities such as antioxidation, detoxification, inflammatory response regulation, and melanin metabolism modulation. It is a key component in maintaining cellular redox homeostasis. This article systematically elaborates on the physicochemical properties, core mechanisms of action, and production processes of reduced glutathione, while comprehensively reviewing the application regulations of this raw material in the food and cosmetics fields. It provides theoretical and regulatory support for raw material research and development, formulation implementation, product compliance filing, and market-oriented application.
