Glutathione (GSH) is a tripeptide composed of glutamate, cysteine and glycine, and is one of the most important intracellular antioxidants and detoxification agents in human biology. It participates in redox balance, phase II biotransformation of xenobiotics and protection of cellular components against oxidative damage. Depletion of glutathione has been associated with oxidative stress, inflammation, ageing and various chronic diseases.
Glutathione from TCS INDUSTRIES LIMITED is supplied as reduced glutathione (GSH) for use in pharmaceuticals, injectables in certain markets, nutraceuticals, functional foods and advanced cosmetic products. In supplements, GSH is positioned for detox support, immune health, liver function and skin brightening, while in topical products it is often used in brightening serums, masks and creams targeted at uneven tone and environmental stress.
Within the TCS portfolio, glutathione is closely related to its oxidised counterpart
and together they define the GSH/GSSG redox pair frequently measured as a biomarker of oxidative status. The ability to source both forms from a single supplier simplifies analytical reference, method development and specialised formulation projects where redox cycling is studied or leveraged.
Glutathione also fits naturally into broader antioxidant and cell-protection concepts that include:
- Ergothioneine – a diet-derived antioxidant that accumulates in high-stress tissues and can complement glutathione in “cellular defence” formulations.
- Ectoin – an osmolyte that protects cells from environmental stress and supports barrier function, making it a strong partner for GSH in topical “urban defence” or sensitive-skin products.
In pharmaceutical contexts, glutathione can be considered under the
Active Pharmaceutical Ingredient
umbrella, especially where parenteral or high-purity formulations are required. Stability, oxidation control and packaging are critical; formulators must manage pH, temperature and exposure to oxygen and light to preserve GSH in its reduced, active form.
By sourcing Glutathione (GSH) from TCS GROUP, brands and manufacturers gain access to a central redox and detoxification molecule with strong scientific backing, supported by a portfolio of synergistic antioxidants and protective actives.
