Glutathione

What is Glutathione?

Glutathione an endogenous tripeptide (γ-L-glutamyl-L-cysteinylglycine) recognized as the master antioxidant in mammalian systems, characterized by:

1. Redox Hub：Scavenges free radicals via thiol (-SH) group and regenerates vitamins C/E
2. Detoxification Catalyst：Conjugates with toxins/heavy metals in hepatic Phase II detox to form mercapturic acid
3. Cellular Protector：Maintains protein thiol status and shields mitochondrial DNA from oxidative stress
4. Skin Brightening Modulator：Inhibits tyrosinase activation pathway to disrupt melanogenesis

Industrial Significance:
Pharmaceutical-grade (≥99%) glutathione serves as a key active in skin-whitening cosmeceuticals, liver-protective nutraceuticals, and clinical adjuvants, valued for its dual bio-essential and commercial versatility.

                                   

Applications:

1. 🔬 Pharmaceuticals

   • Adjuvant therapy for hepatic disorders (alcoholic/fatty liver)

   • Radioprotective agent in chemotherapy

   • Neuroprotective research for Parkinson’s disease

   💊 Nutraceuticals

   • Oral whitening capsules/antioxidant supplements

   • Core active in detox & liver protection formulas

   • Immune-boosting functional foods

   💄 Cosmeceuticals

   • Brightening serums/spot correctors (alternative to arbutin)

   • Anti-aging synergist (Glutathione + VC combos)

   • Lyophilized powders/ampoule preparations

Fuctions:

✅ Triple Antioxidant Action
→ Direct free radical scavenging | → Vitamins C/E regeneration | → SOD/GPx activation
✅ Master Detoxifier
Chelates heavy metals & toxins into excretable complexes
✅ Melanin Synthesis Inhibitor
Blocks tyrosinase pathway for even skin tone
