Our plant, established in 2010, ensures uniform quality control with ISO 22000, HACCP, Kosher and Halal certifications. This white crystalline powder has an optimum specific rotation of between -15.5° and -17.5° which ensures the maximum biological activity. Our product gives the best antioxidant efficacy for whitening supplements, liver detox formulas and anti-aging skin care with oxidised glutathione (GSSG) ratio of <1.5% in controlled oxidation. We stock and ship to over 100 countries within 1-3 working days.

Product Specifications

Superior Biological Activity

The reduced form (GSH) is the active form of the antioxidant. It is the reduced form that efficiently donates electrons and neutralises free radicals. Unlike oxidised glutathione (GSSG), our product retains the important sulfhydryl (-SH) group involved in detoxification pathways.

Our fermentation-derived product guarantees the right L-configuration, ensuring maximum absorption into cells, unlike synthetic alternatives. It has a molecular weight of 307.32 g/mol and a water solubility of ~100 mg/mL, which makes it simple to add to liquid supplements and skincare serums.

Quality control protocols restrict heavy metals to below 10 ppm. Microbiological testing shows total plate counts less than 1000 cfu/g, meeting pharmaceutical grade requirements for sensitive applications.

Versatile Application Portfolio

Health Supplement Formulations

Your whitening supplement products are powered by skin brightening qualities that suppress melanin development. The powder fully dissolves in liquid drinks thus it is perfect for pre-made detox cocktails.

Liver support products take use of glutathione's function in Phase II detoxification. There is evidence of efficacy in clinical trials for hepatic health maintenance at doses of 250-500mg daily.

Cosmetic & Skin Care Integration

This chemical is used in age-defying lotions and serums because it is a free-radical scavenger. The tiny particle size that passes 80 mesh provides a smooth texture in topical treatments.

Masks and spot treatments with brightening properties have concentrations of 2-5% for observable benefits. It is stable in compositions in the pH range 3.0-6.0, which is typical for cosmetic emulsions.

Manufacturing Excellence

We synthesise glutathione with better chirality than chemical synthesis by enzymatic fermentation with the help of saccharomyces cerevisiae. This biotech technique lowers residual organic solvents and improves safety profiles.

The manufacturing facility is ISO 22000, HACCP compliant and batch tested to EP10 and USP43 monographs. The integrity of the structure is confirmed by the specific rotation readings of -15.5° to -17.5°.

Loss on drying is kept below 5% by temperature controlled drying techniques. The 5% ash limit ensures mineral purity required for medicinal use.

Stability & Storage Optimization

L-Glutathione Reduced Powder must be stored in sealed containers below 25°C to prevent moisture absorption. Our desiccant loaded aluminium foil wrapping avoids oxidative yellowing for the 24 month shelf life.

Yellowing suggests oxidation due to moisture or UV exposure. Your receiving protocols should test for the typical sulphurous odour – absence of odour denotes loss of potency.

The powder can be processed at temperatures of up to 80°C for 120 min without loss of immune-supporting qualities. This heat stability is useful for hot-fill beverage applications and encapsulation operations.

FAQ

Q: Why does the powder smell like sulphur?

A: The active sulfhydryl (-SH) group is responsible for the smell. If products lack this quality they may have oxidised or lost efficacy while being stored.

Q: How can I avoid yellowing when storing?

A: Keep in dark and dry place below 25°C. Yellowing indicates oxidation caused by moisture or sun exposure. Immediately reseal containers after use.

Q: What's the difference between GSH and GSSG?

A: GSH is the active reduced form, which gives antioxidant effects. GSSG is the oxidised form that is biologically inactive. Quality lots include <1.5% GSSG.

Q: Is this the fermented or synthetic glutathione?

A: Our product is made by enzymatic fermentation using Saccharomyces cerevisiae and has the right L-configuration for optimal bioavailability against synthetic procedures.

Q: Does it match international norms of pharmacopoeia?

A: Yes. Batches are evaluated against USP43 and EP10 monographs for assay, specific rotation and impurity profiles appropriate to pharmaceutical and dietary supplement grades.
