Glutathione

Glutathione (CAS 70-18-8), also known as GSH, is a tripeptide antioxidant produced through fermentation.

Where is Glutathione used?

• Pharmaceuticals: active ingredient in injectables, oral supplements and lyophilized drug formulations
• Food and beverage: antioxidant that extends shelf life
• Bakery: modifies gluten structure to improve processing performance
• Cosmetics: skin-brightening serums, creams and topical products targeting uneven skin tone through melanin pathway modulation
• Biotechnology: reagent in cell culture media and protein purification, particularly for refolding disulfide-bonded proteins
• It functions as a reducing agent and antioxidant stabilizer, protecting formulations and biological systems from oxidative degradation.

Good to know: Reduced glutathione is the predominant commercial form for industrial-scale procurement.
