Product Overview
Reduced Glutathione Powder is a high-purity tripeptide ingredient commonly used in supplement, cosmetic, functional nutrition, and formulation projects. It is usually supplied as white to almost white crystalline powder with 99% assay, USP, EP, JP, CP, or agreed specifications, and buyers often review assay, identification, solubility, related substances, residual solvents, and document scope before technical or commercial evaluation. It is commonly considered for capsules, tablets, powder blends, cosmetic formulas, and nutrition products, with sample support and batch documents available for sourcing reference.

Applications
Dietary Supplements
Reduced glutathione powder is commonly used in capsule, tablet, and powder supplement projects where buyers need a high-purity GSH ingredient with defined assay and batch documentation. It is suitable for formulas positioned around antioxidant nutrition, beauty-from-within concepts, and premium supplement blends.
Cosmetic Formulations
For cosmetic and personal care projects, reduced glutathione may be reviewed as a functional cosmetic raw material for brightening-positioned or antioxidant-oriented formulations. Buyers should confirm regulatory status, formula compatibility, solubility, pH range, and stability before commercial use.
Functional Nutrition Products
Reduced glutathione powder can be considered for functional nutrition, sachet, and powder blend concepts where water solubility and defined assay are important. Taste, stability, dosage design, and compatibility with other nutrients should be checked in the final formula.
Formulation Development
For R&D and formulation projects, reduced glutathione powder provides a standard GSH route compared with S-acetyl glutathione, liposomal glutathione, or injectable-grade materials. The suitable form should be selected according to stability target, dosage form, regulatory route, and document requirements.
How to Choose the Right Grade / Form
For standard supplement formulas
Recommended direction: 99% reduced glutathione powder. High-purity GSH powder is commonly selected for capsules, tablets, and powder blends where the buyer needs a defined assay and standard raw material format.
For pharmacopeial specification projects
Recommended direction: USP / EP / JP / CP or agreed specification. Pharmacopeial or buyer-defined standards are more suitable when the project requires tighter identification, impurity, and document review.
For stability-focused premium formulas
Recommended direction: S-Acetyl-L-Glutathione. S-acetyl glutathione is a derivative route that may be considered when the project focuses on differentiated stability or premium supplement positioning.
For delivery-system formulas
Recommended direction: Liposomal Glutathione Powder. Liposomal or carrier-based glutathione products should be evaluated separately because they are formulation systems, not the same as pure reduced glutathione powder.
Specification confirmation
Buyers should confirm assay, standard, application route, related substances, residual solvents, heavy metals, microbial limits, COA format, and additional document needs before sample or bulk order confirmation.
Technical & Formulation Notes
Technical Notes
Technical Notes
Reduced glutathione powder is mainly evaluated by assay, identification, appearance, solubility, optical rotation, related substances, loss on drying, residue on ignition, and microbiological quality. Buyers should confirm whether the project requires food-grade, supplement-grade, cosmetic-grade, pharmacopeial-grade, or agreed specification before comparing quotations.
Manufacturing & Process
Manufacturing & Process
Reduced glutathione is commonly produced through fermentation, enzymatic, or other controlled manufacturing routes depending on supplier process and target specification. Process control focuses on purity, impurity profile, residual solvent control, moisture, particle behavior, and batch consistency.
Compatibility / Formulation Notes
For capsules and tablets, reduced glutathione powder should be evaluated for assay, particle behavior, flowability, compatibility with excipients, and moisture sensitivity.
For powder blends and sachets, taste profile, water solubility, stability, and compatibility with vitamins, minerals, amino acids, and botanical ingredients should be tested in the final formula.
For cosmetic systems, pH, water phase compatibility, oxidation sensitivity, fragrance compatibility, and preservative system should be reviewed before scale-up.
For functional beverages or aqueous formulas, solubility and stability should be tested under the real pH, heat, light, and storage conditions.
During storage and handling, reduced glutathione powder should be protected from moisture, heat, strong light, oxidizing agents, and prolonged open-air exposure.
Extended QC & Test Items
Extended QC & Test Items
Common review items include assay, identification, optical rotation, appearance, pH, chloride, sulfate, ammonium, iron, heavy metals, related substances, loss on drying, residue on ignition, residual solvents, microbiology, and batch documentation. Additional tests can be discussed according to destination market, application route, and buyer specification requirements.

Storage, Shelf Life & Packaging
Storage
Store reduced glutathione powder in a tightly sealed original container in a cool, dry, and well-ventilated place. Keep away from moisture, heat, strong light, oxidizing agents, and strong odors. After opening, reseal the package immediately and use under clean, dry handling conditions.
Shelf Life
Shelf life is usually reviewed according to the agreed specification, packaging, and storage conditions. Under proper storage, reduced glutathione powder is commonly assigned a practical shelf life based on batch COA and supplier documentation. Buyers should avoid prolonged exposure to humidity, heat, and open air.

FAQ
1) What is Reduced Glutathione Powder?
Reduced Glutathione Powder is the reduced form of glutathione, also known as L-glutathione reduced or GSH. It is commonly supplied as a high-purity crystalline powder for supplement, cosmetic, functional nutrition, and formulation projects.
2) What specifications can you supply?
We can discuss 99% assay, USP, EP, JP, CP, or other agreed specifications depending on project requirements, application route, and availability.
3) Is reduced glutathione powder water-soluble?
Yes, reduced glutathione powder is generally soluble in water. Final solubility and stability should still be tested in the actual formulation system.
4) What is the difference between reduced glutathione and S-acetyl glutathione?
Reduced glutathione is the standard GSH raw material, while S-acetyl glutathione is a derivative route often reviewed for differentiated stability or premium formulation positioning. They should be evaluated as separate products.
5) Can this page be used for injectable glutathione?
No. This page is positioned for reduced glutathione powder as a general raw material. Injectable-grade glutathione should be reviewed separately with stricter quality, compliance, and pharmaceutical manufacturing requirements.
6) Can you provide documents for technical review?
Yes. COA, SDS/MSDS, TDS, and specification documents are available. Additional documents may depend on product grade, application route, destination market, and buyer requirements.
