Why Choose Us?
Advanced Bio-Fermentation Technology
We use food grade glucose, amino acid substrates and probiotic microorganisms in closed fermentation systems. This biological reaction in the aqueous phase obviates chemical synthesis stages, assuring product safety and natural origin.
System of Thorough Quality Control
Each batch is fully tested for compliance, including heavy metal screening, microbiological testing and purity verification using state of the art testing equipment. Third party testing assures transparency and reliability.
Global Supply Chain & Customising Ability
We have a logistics network across international market with effective inventory management and fast delivery. We provide OEM/ODM services with versatile dosage forms including Powder, tablets, hard capsules and soft capsules to fulfil your various formulation demands.

All products meet with EU EC396 and EU 2023/915 standards with strict solvent residue limits. We are committed to E-E-A-T principles and provide authoritative, trustworthy, science-backed product information.
Production Process
Our full biological fermentation process maintains product integrity from raw material to finished powder:
Activation of Strains & Sterile Culture：Sterile conditions are used to activate edible fermentation strains with high activity to prevent contamination.
Aseptic Medium Preparation & Sterilization：Sterilise food-grade amino acid and sugar media at high temperature to establish a pure base for fermentation.
Enzymatic Synthesis and Closed Deep Liquid Fermentation：Constant temperature and oxygen-controlled fermentation guides the synthesis of Reduced L Glutathione Powder, minimising the creation of inactive isomers.
Fermentation Broth Sterilisation & Separation of Solid and Liquid：The mycelium and solid residues are removed by multi-stage precision filtration to obtain the crude glutathione solution.
Ultrafiltration Membrane for Impurities Removal: Membrane separation technology for the removal of macromolecular proteins, polysaccharides and metabolic contaminants.
Ion Exchange Resin Desalting and Deep Purifing: Inorganic salts and trace ionic contaminants are eliminated, leading to increased whiteness and purity of the product.
Vacuum Concentration at Low Temperatures: Without light, the low temperature concentration avoids thermal oxidation and maintains the molecular framework.
Gradient Recrystallisation Precision Refinement: High purity crystalline is obtained after removal of trace isomer impurities.
Low Temperature Vacuum Drying & Powderization: It has stable physical and chemical properties and gives a uniform white crystalline powder.
Sieving, Batch Homogenisation & Vacuum Packing: Batch variances are eliminated by means of precision sieving and 3D blending. Nitrogen packed aluminium foil bags, double layer, protected from moisture, light and oxygen by outer fibre drums.
Warehousing Full Inspection & Traceability: Each batch is tested extensively against historical data allowing full traceability.
