Product Identity | Active Form Meets Liposomal Engineering
Liposomal L-Glutathione is a stabilized, high-bioavailability form of reduced glutathione (GSH), encapsulated within phospholipid vesicles to ensure efficient delivery and protection against degradation.
- Active Ingredient: L-Glutathione (Reduced Form, GSH)
- Assay: 50% / 70% (customizable)
- Production Method: Fermentation-derived, vegan compliant
- Dosage Form: Liposomal powder (water-dispersible)
- Carrier System: Sunflower Lecithin + Phytosterols
- Appearance: Off-white to light yellow powder
- Structure: Nano liposomal vesicles (confirmed by TEM imaging)
Engineered for formulations targeting cellular detoxification, antioxidant defense, and skin health.
Absorption Breakthrough | Solving Glutathione Instability & Degradation
Glutathione is a critical intracellular antioxidant, but conventional oral delivery faces major challenges:
- Highly prone to oxidation (GSH → GSSG)
- Degraded by digestive enzymes
- Limited transport across intestinal membranes
These limitations result in low bioavailability and reduced efficacy.
Liposomal Advantage
- Encapsulation shields glutathione from oxidation and enzymatic breakdown
- Lipid bilayers enable direct cellular uptake via membrane fusion
- Improves systemic circulation stability
➡ Result: 2–5× higher bioavailability vs conventional glutathione powder

FAQ | Buyer-Oriented Technical Clarifications
1. Why is liposomal glutathione more effective than regular GSH?
Because it protects glutathione from oxidation and enzymatic degradation, enabling significantly higher absorption.
2. Is this product suitable for liquid formulations?
Yes, it is designed to disperse in water and works well in liposomal drinks and oral liquids.
3. What makes glutathione particularly unstable?
Its thiol group is highly reactive, making it prone to oxidation without protective encapsulation.
4. Which carrier system is best for antioxidant stability?
Lecithin combined with phytosterols provides enhanced oxidative stability and is widely recommended.
5. How do you confirm liposomal structure?
TEM imaging is provided to verify vesicle formation and morphology.
6. Are regulatory documents available for export?
Yes, including COA, HPLC reports, and certificates required for global trade.
7. Can this ingredient be combined with other actives?
Yes, co-encapsulation with vitamin C, NMN, or other antioxidants is available.
8. What are the storage recommendations?
Store sealed, away from light, at 2–8°C. Shelf life is typically 18–24 months.
