Reduced Glutathione is an antioxidant found in almost every cell in the body and plays a role in the detoxification of drugs and exogenous substances.In addition, reduced glutathione (GSH) acts as a hydrogen donor in the detoxification of hydrogen peroxide.As a dietary supplement,GSH has various systemic effects such as improving liver abnormalities, improving diabetic complications, preventing viral infections, anti-tumor activity, etc., and is even used to treat autism.Reduced glutathione is also widely used in skin whitening skin care products, especially in the Asian market.Skin care products containing 0.1% and 0.5% glutathione are effective for whitening facial skin.

★What is the difference between Reduced Glutathione (GSH) and Oxidized Glutathione (GSSG)?

Reduced Glutathione (GSH) is the active, functional form that neutralizes free radicals, while GSSG is the spent (oxidized) version. For supplements and cosmetics, suppliers always recommend the Reduced form (GSH) due to its direct bio-activity. Our factory focuses on producing stable GSH with 98% purity.

★Is Reduced Glutathione effectively absorbed when taken orally?

While traditional oral glutathione has limited absorption, modern formulations like liposomal or sublingual delivery significantly enhance bioavailability. As expert suppliers, we provide fine mesh powder that is ideal for advanced delivery systems, ensuring maximum efficacy for your end consumers.

★What is the standard purity of Reduced Glutathione for supplements?

The industry standard for premium L-Glutathione is 98%. At ZHENYIBIO, our factory utilizes enzymatic fermentation to achieve 99% purity, meeting USP and EP pharmaceutical-grade standards, which is preferred by global manufacturers.

★How to maintain the stability of Reduced Glutathione in formulations?

L-Glutathione is sensitive to oxidation. We recommend maintaining a pH between 3.0 and 5.0 and adding antioxidants like Vitamin C to stabilize the formula. Our technical team supports manufacturers in optimizing their product shelf life.

★What is the recommended dosage of Reduced Glutathione for skin whitening?

Typical oral dosages range from 250mg to 500mg per day. For professional formulations, we suggest manufacturers consult local regulations. FZBIOTECH provides bulk powder to support large-scale production for global suppliers.

★Why is Reduced Glutathione often combined with Vitamin C?

Vitamin C helps regenerate "spent" glutathione and increases its levels in the blood. This synergy enhances the whitening and antioxidant effects, a popular choice for high-end supplement manufacturers.

★Is ZHENYIBIO's Reduced Glutathione vegan and non-GMO?

Yes, our L-Glutathione is 100% vegan-friendly and non-GMO, meeting the growing demand for plant-based and clean ingredients in the global market.
