Reduced L-Glutathione (GSH) is a tripeptide composed of glutamic acid, cysteine, and glycine, serving as a primary antioxidant in the body. Our Glutathione Powder is a high-purity, fermentation-derived ingredient engineered for maximum bioavailability and stability. Produced under stringent GMP conditions, it is a benchmark material for formulators in the nutraceutical, cosmetic, and functional food industries seeking a reliable and effective source of GSH. Its excellent water solubility and neutral sensory profile make it a versatile component for a wide range of applications, from anti-aging supplements to skin-brightening serums.
As the original manufacturer and exporter, we provide full batch traceability and consistent quality, ensuring your formulation performs as intended, every time.

Our Reduced L-Glutathione powder is designed for versatility and ease of use in various delivery systems.
Q1: What is the manufacturing process for your Glutathione powder?
A: Our L-Glutathione is produced via a controlled microbial fermentation process, followed by multi-step purification and crystallization to achieve high purity and stability. This method is more sustainable and yields a product with a superior purity profile compared to chemical synthesis.
Q2: Do you supply directly from the factory?
A: Yes, we are the original manufacturer and global supplier. Purchasing from us ensures you receive a genuine, high-quality product with full traceability, technical support, and competitive factory-direct pricing.
Q3: What is the difference between Reduced L-Glutathione (GSH) and Oxidized Glutathione (GSSG)?
A: GSH is the active, antioxidant form of glutathione. GSSG is the oxidized, inactive form. A low GSSG content in the powder is a critical indicator of high quality, freshness, and careful manufacturing, as it signifies the product has not degraded.
Q4: Can I get a sample for formulation testing?
A: Absolutely. We encourage R&D testing. You can request a sample for evaluation through the contact form below. Please specify your application so we can provide relevant documentation.
Q5: What is the Minimum Order Quantity (MOQ)?
A: Our standard MOQ is 25 kg. For smaller quantities for trial runs or specific projects, please contact our sales team to discuss available options.
