Premium Reduced Glutathione Powder: The Master Antioxidant
L-Glutathione Reduced is a tripeptide (γ-L-glutamyl-L-cysteinylglycine) endogenously produced in cells. It serves as the body’s primary and most crucial water-soluble antioxidant, playing an indispensable role in detoxification, immune function, cellular protection, and redox balance. Our product offers the bioactive, reduced form (GSH), which is directly utilizable by the body, unlike its oxidized counterpart (GSSG).

The Antioxidant Network: Synergistic Power with Other Ingredients
Glutathione’s efficacy is dramatically enhanced when combined with key synergistic nutrients. As the “master antioxidant,” it works within a network. Vitamin C regenerates oxidized glutathione back to its active reduced form. Alpha-Lipoic Acid is unique—it regenerates glutathione, vitamin C, and vitamin E, and is itself a potent antioxidant. Selenium (as selenized yeast) is the essential cofactor for glutathione peroxidase, the enzyme that utilizes glutathione to neutralize harmful peroxides. Finally, N-Acetylcysteine (NAC) is a direct precursor to glutathione, helping to boost its intracellular levels. Formulating with these combinations from a single, reliable wholesale L-Glutathione Reduced supplier like us ensures product synergy and maximum consumer benefit.

Frequently Asked Questions (FAQ)
L-Glutathione Reduced (GSH) is the active, antioxidant form that directly neutralizes free radicals and toxins. Oxidized Glutathione (GSSG) is the “spent” form after GSH donates its electron. For supplemental or functional use, the Reduced form is biologically preferred, as it is readily usable by cells. Our product guarantees a high percentage of the bioactive Reduced form.
Yes. We produce our reduced glutathione for supplements, functional foods, and cosmetics under strict cGMP guidelines. It meets quality standards for pharmacopeia (USP/EP), food grade, and cosmetic ingredient requirements. We provide the necessary documentation (COA, TDS, MSDS) for your regulatory compliance in various markets.
Dosage depends on the application. For dietary supplements, clinical studies often use 250-1000mg daily. In functional foods/beverages, typical inclusion is 0.01%-0.05%. For cosmetic skin-brightening formulations, 0.5%-2.0% is common. Our technical team can provide specific formulation guidance based on your product concept.
Glutathione is sensitive to oxidation, heat, and high pH. We recommend using airtight, light-resistant packaging with desiccants. In formulations, maintaining a low pH (acidic environment), using antioxidant synergists like vitamin C, and avoiding prolonged high-heat processing enhance stability. We offer stability data and handling guidelines.
We offer flexible packaging to meet diverse needs, from 1kg aluminum foil bags with desiccant for R&D to 25kg fiber drums for buy glutathione bulk production runs. All packaging is designed to minimize moisture and oxygen ingress, ensuring product integrity during storage and transport.
