Reduced L-Glutathione Powder CAS 70-18-8 | Bulk API for Formulation
Reduced L-Glutathione (CAS 70-18-8) supplied by Xi'an Tihealth Biotechnology Co., Ltd. is a high-purity, bio-fermented tripeptide essential for advanced cellular defense and antioxidant formulations. We specialize in providing the active "reduced" form, which is critical for maximizing stability and efficacy in industrial applications.
Manufactured under stringent ISO 9001:2015 quality control protocols, our bulk L-Glutathione powder exhibits excellent solubility and is strictly monitored for heavy metal residues and microbiological limits, making it the ideal raw material for premium dietary supplements, functional foods, and dermatological cosmetic preparations.
Core Manufacturing Advantages of Our L-Glutathione API
- Advanced Bio-Fermentation Process: Sourced through a refined enzymatic biocatalysis process rather than harsh chemical synthesis, ensuring a highly bioavailable active compound that meets strict natural and clean-label formulation standards.
- Enhanced Oxidation Resistance: Utilizing specialized vacuum-drying techniques and inert gas packaging to protect the highly sensitive sulfhydryl (-SH) group. This guarantees the product remains predominantly in its active "reduced" state without premature oxidation during global transit.
- Organoleptic Optimization (Odor Mitigation): Advanced multi-stage purification steps significantly reduce the characteristic sulfurous odor typically associated with bulk glutathione, making it exceptionally suitable for premium oral liquids, gummies, and high-end cosmetic serums.
- Optimized Particle Size Distribution: Finely milled to specific mesh requirements, ensuring rapid aqueous solubility, uniform dispersion, and excellent flowability-critical parameters for high-speed tableting and encapsulation lines.

Frequently Asked Questions
Is this the Reduced or Oxidized form of Glutathione?
We exclusively supply the active Reduced form (L-Glutathione) API powder. This form maintains the critical free sulfhydryl (-SH) group necessary for effective antioxidant neutralization and cellular defense in premium cosmetic and nutraceutical formulations.
How do you control the strong sulfur odor typical of bulk glutathione?
Through our advanced bio-fermentation and multi-stage crystallization processes, we significantly mitigate the volatile sulfurous compounds. This provides a highly optimized organoleptic profile, making it much easier to mask in gummies, sublinguals, and oral liquid formulations.
What is the standard packaging to prevent oxidation during transit?
For bulk commercial orders, our standard packaging consists of 25kg fiber drums lined with double-layered, pharmaceutical-grade polyethylene bags. The inner bags are vacuum-sealed or flushed with inert gas to completely isolate the powder from moisture and oxygen, ensuring long-term stability.
