Product Overview

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.

Unique Advantages:

  • Superior Purity & Low Impurities: With a typical assay of 99.5% by HPLC and an oxidized form (GSSG) level consistently below 0.5%, our GSH ensures maximum potency and stability in your final product.
  • Excellent Formulation Performance: Optimized particle size and high solubility prevent processing issues, ensuring homogeneity in blends, clear solutions in beverages, and smooth textures in topical applications.
  • Direct-from-Factory Supply Chain: Sourcing directly from our factory guarantees competitive pricing, stable lead times, and comprehensive technical support from our expert team.
  • Comprehensive Documentation: Each batch is supplied with a detailed Certificate of Analysis (COA) and a full set of regulatory documents to support your quality and compliance needs.

Application & Formulation Guidance

Our Reduced L-Glutathione powder is designed for versatility and ease of use in various delivery systems.

  • Dietary Supplements:
    • Dosage Form: Hard-shell capsules, tablets, powders.
    • Recommended Dosage: 50 mg – 500 mg per serving.
    • Formulation Tip: For enhanced stability and synergistic effects, formulate with antioxidants like Vitamin C and Alpha-Lipoic Acid. Its excellent flowability is suitable for direct compression and high-speed encapsulation.
  • Functional Foods & Beverages:
    • Dosage Form: Ready-to-mix powders, shots, functional drinks.
    • Formulation Tip: GSH is highly water-soluble. For liquid applications, add it during the final mixing stage and keep the pH between 4.0 and 6.0 for optimal stability. Its clean taste profile requires minimal flavor masking.
  • Cosmetics & Skincare:
    • Dosage Form: Serums, lotions, creams, face masks.
    • Recommended Concentration: 0.5% – 2.0%.
    • Formulation Tip: Incorporate into the water phase of an emulsion at temperatures below 40°C (104°F) to prevent degradation. It is most stable in formulations with a final pH between 5.0 and 6.5. Pair with Vitamin C and Ferulic Acid to enhance its skin-brightening and antioxidant properties.

Stability & Storage Recommendations

  • Stability: Reduced L-Glutathione is sensitive to oxidation, high temperatures, and high pH environments. The presence of transition metal ions can accelerate degradation.
  • Storage: Store in a cool, dry place, away from direct sunlight. Keep the container tightly sealed to prevent moisture absorption and oxidation.
  • Shelf Life: 24 months from the date of manufacture when stored under recommended conditions.

Frequently Asked Questions (FAQ)

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.
