Product Description: Glutathione (GSH), a tripeptide containing a γ-amide bond and a sulfhydryl group, is composed of glutamic acid, cysteine, and glycine. It is present in nearly every cell of the body.
Glutathione (GSH) is a naturally occurring tripeptide composed of three amino acids — glutamic acid, cysteine, and glycine — linked by a γ-amide bond. It is present in nearly every cell of the human body and serves as the primary intracellular non-protein thiol antioxidant.
As a low molecular weight thiol-tripeptide, GSH plays a central role in antioxidant defense, detoxification, and cellular metabolism. It neutralizes reactive oxygen species (ROS), protects cellular components from oxidative damage, and maintains redox balance within cells. The thiol (-SH) group in GSH inhibits tyrosinase — the key enzyme in melanin synthesis — helping to reduce pigmentation and even out skin tone.
Our Glutathione is manufactured to ≥98% purity with strict quality control, suitable for applications across the cosmetics, food/nutraceutical, and pharmaceutical industries. The global glutathione market is experiencing robust growth, driven by increasing demand for antioxidant ingredients in skincare, dietary supplements, and pharmaceutical applications.
Solubility: Soluble in water, dilute alcohol, liquid ammonia, and methylformamide; insoluble in alcohol, ether, and acetone.
Functions: Glutathione helps maintain normal immune system function and possesses antioxidant, skin-whitening, spot-fading, anti-aging, immune-boosting, anti-tumor, and detoxifying properties. It is applicable not only in pharmaceuticals but also as a food additive and cosmetic ingredient.
Glutathione exerts its biological activities through multiple pathways:
1. Antioxidant Defense
As the primary intracellular non-protein thiol, GSH neutralizes reactive oxygen species (ROS) such as hydroxyl radicals (·OH) and superoxide anions (·O₂⁻)
Maintains the intracellular redox environment essential for cellular survival and metabolic activity
2. Skin Brightening & Tyrosinase Inhibition
The thiol (-SH) group inhibits tyrosinase, the key enzyme in melanin synthesis
Converts dark pigmentation (eumelanin) into light pigmentation (phaeomelanin)
3. Detoxification
Forms conjugates with harmful substances via glutathione S-transferase (GST), promoting cellular detoxification
4. Immune Support
Participates in the γ-glutamyl cycle to store and transport cysteine
Supports leukocyte production and enhances immune defense
Clinical studies have demonstrated that topical glutathione can significantly reduce ultraviolet-induced erythema (p=0.0003), decrease melanin index (p<0.05), and improve skin elasticity and wrinkle reduction (p<0.01).
GSH is incorporated into a wide variety of cosmetic formulations including serums, creams, lotions, masks, soothing gels, and water-soluble liquids or powders. Liposomal or microencapsulated forms are often used to improve stability and skin penetration.
