L-Glutathione
CAS 70-18-8

Applications

1.Oral nutrition and beauty dietary Supplements:

It is widely used to produce oral beauty products, wellness capsules and tablets. In skincare sector, it delivers skin brightening and anti-aging benefits. In healthy market, it protects the liver effectively, relieves hangover, eliminates heavy metals and internal toxins, and alleviates late-night fatigue and chronic tiredness.

2.Pharmaceuticals:

L-glutathione, as a high-purity pharmaceutical-grade raw material, is widely used to help protect the liver and alleviate poisoning from drugs and heavy metals in clinical. In addition, it is commonly used as a key active ingredient in advanced medical aesthetics, such as Rejuvenating & Brightening Vitality Shots and IV Drips.

3.Cosmetics & Skincare:

As a star active ingredient in luxury anti-aging and brightening skincare, it is widely used to premium serums, intensive repair masks and anti-aging creams. The main function is to eliminate melanin, in other words, it precisely fades stubborn pigmentation, physically blocks melanin signal transduction, and powerfully eliminates dullness to brighten skin tone by inhibiting tyrosinase activity. What’s more, it can work together with vitamin C and niacinamide to create a powerful synergistic effect, repairing photoaging and revealing clear, flawless skin.

Specifications

Advantages

1.We carry out biological fermentation using natural Non-GMO yeast strains. We then apply multi-stage precision crystallization and membrane separation in the follow-up procedures. These processes bring the product purity up to 98% and above, based on HPLC testing. We also remove all substances that produce off-odors, and the final product is a snow-white, odor-free powder.

2.The crystal structure is optimized and the specific surface area of the powder is reduced. In addition, we adopt exclusive fresh-locking packaging: high-barrier aluminum foil vacuum packaging with inert gas protection via nitrogen replacement. In conclusion, the raw material’s stability tolerance is several times higher at both physical and chemical levels.

3.We comply with GMP-based fine chemical production standards. These products don’t have any residual organic solvents, and levels of lead, arsenic and mercury are kept under 0.1 ppm and often undetectable, well below the strictest international safety limits. In addition, we also provide TDS, MSDS and COA.

FAQ

Q1：What are the purity specifications of your L-glutathione？Is the product in its reduced form or oxidized form?

A：The premium L-glutathione (GSH), tested via High Performance Liquid Chromatography (HPLC), achieves a purity of up to 98%, which meets premium application standards for cosmetics and dietary supplements. Our material comes in fully active reduced glutathione form, the only bioactive variant that scavenges free radicals, metabolizes toxins and suppresses melanin formation. It should not be confused with oxidized glutathione (GSSG) that does not possess these biological benefits.

Q2：How do you control the odor of your glutathione, given that many suppliers’ glutathione has a strong pungent sulfur smell?

A: The pungent odor stems from outdated separation processes that leaves sulfur-containing impurities behind. In contrast, we adopt an entirely green, non-GMO bio-fermentation process, with proprietary multi-stage crystallization and membrane separation technologies, which eliminates odor-causing impurities entirely. Our finished product is an odorless, snow-white powder. Formulators won’t have to add expensive masking agents or synthetic fragrances when creating end products.

Q3: How do you guarantee product stability during global shipping, given that L-glutathione (GSH) is highly susceptible to oxidation and moisture?

A: At the production phase, we refine the crystal structure to lower the powder’s specific surface area and lessen its reactivity when exposed to ambient air. For logistics transport, bulk goods are packed in custom high-barrier aluminum foil bags. We fully evacuate the air and refill each bag with inert nitrogen to cut off air contact. This heavy-duty airtight packaging prevents any loss of the raw material’s activity during long ocean transit and extended storage.

Q4: How is the water solubility of your L-Glutathione? What formulation recommendations do you have for skin serum products?

A: Our L-glutathione boasts excellent water solubility and dissolves into a fully clear solution free of sediment. For skincare formulations, L-glutathione remains highly stable under weakly acidic conditions ranging from pH 3.5 to 5.5. Besides, when formulated alongside antioxidants including vitamin C, vitamin E and alpha-arbutin, it delivers markedly stronger synergistic antioxidant benefits.
