Description

Glutathione CAS NO 70-18-8 is a vital tripeptide composed of glutamic acid, cysteine, and glycine, serving as a master antioxidant in biological systems. Its primary commercial value lies in its potent reducing power, which is critical for maintaining cellular redox balance and detoxification processes. This essential compound is in high demand across the pharmaceutical, nutraceutical, cosmetic, and food industries for applications ranging from active pharmaceutical ingredients (APIs) and dietary supplements to skin-whitening agents and food preservatives.

Application

• Pharmaceutical Active Ingredient (API): Used in formulations for liver protection, detoxification therapies, and as an adjunct in treatments for conditions like Parkinson's disease and chemotherapy-induced toxicity.
• Dietary Supplements & Nutraceuticals: A key ingredient in capsules, tablets, and powders aimed at boosting immune function, supporting antioxidant defense, and promoting overall wellness.
• Cosmetics & Skincare: Incorporated into serums, creams, and lotions for its skin-brightening, anti-aging, and antioxidant properties to reduce hyperpigmentation and protect against environmental damage.
• Food & Beverage Industry: Utilized as a natural preservative and antioxidant to prevent spoilage and maintain the color and flavor of food products.
• Research & Biochemical Reagents: Serves as a critical reagent in cell culture media, enzymatic studies, and biochemical research investigating oxidative stress pathways.
• Animal Feed Additives: Added to enhance the health, growth performance, and antioxidant status of livestock and poultry.
