What Is Bulk Glutathione Powder?

Reduced glutathione (GSH) is the active tripeptide consisting of glutamic acid, cysteine, and glycine. The reduced form, unlike the oxidised (GSSG), retains the essential sulfhydryl (-SH) group for electron donation and antioxidant activity in the cell.

Our product is manufactured thru enzymatic fermentation by Saccharomyces cerevisiae to preserve the bioactive L-configuration necessary for intracellular absorption. This pharmaceutical quality powder is water soluble, with no bitter aftertaste and is suited for big batch production of whitening supplement and skincare formulations.

The herbal odour of sulphur is indicative of the lifestyles of active sulfhydryl corporations. In case you do not get that awesome smell, it's commonly a signal the oil has oxidised and is weaker.

Core Advantages for B2B Manufacturing

Excellent Retention of Bioavailability

Advanced fermentation technique keeps the maximum electron donating capacity than chemical synthesis approaches. The intact sulfhydryl structure guarantees the best intracellular antioxidant efficacy in finished compositions.

Better Solubility Profile

The micronised powder is very soluble in aqueous systems at room temperature. This allows you to avoid the formulation issues typically experienced with coarse-grade materials, simplifying your production cycle.

High Purity (Pharmaceutical Grade)

Each batch conforms to USP and EP monograph specifications for assay, specific rotation and impurity profiles. We control the heavy metal level below the legal limits of EU (≤10 ppm) and therefore it is in accordance with the worldwide markets.

Reliable Raw Material Supply

We have a vertically integrated production approach that includes unique fermentation and quality-controlled packaging. This configuration removes supply chain variability and assures consistent lot-to-lot performance for high-volume orders.

Application Solutions

Skin Brightening Supplements: Primary antioxidant in the cell decreases tyrosinase activity, thereby inhibiting melanin formation and systemic skin tone enhancement.

Liver Support Formulations: Aids in phase II detoxification pathways via conjugation reactions, perfect for detox and hepatoprotective supplement blends.

Anti-Aging Skincare: Targets oxidative stress markers at the cellular level to neutralise reactive oxygen species (ROS) in luxury cosmetic serums and creams.

Sports Nutrition Products: Decreases exercise-induced oxidative damage and aids in recovery routines in performance supplement lines.

Storage and Stability Guidelines

Store Bulk Glutathione Powder in sealed containers, in a cool, dry place, below 25°C. Yellowing is a sign of accelerated oxidation, caused by exposure to moisture, UV light or alkaline pH (8.0-10.0).

The powder is stable at pH conditions of 3.0-5.0 and is acceptable for most oral supplement formulations. For liquid applications that require a neutral pH, consider microencapsulation or other liposomal delivery techniques to prevent degradation.

Material properly stored is potent for 24 months from date of manufacture .

Packaging & Shipping

We offer flexible packaging options to accommodate diverse order volumes:

• 1kg aluminum foil bags for trial production runs
• 5kg boxes for mid-scale formulation development
• 25kg fiber drums for commercial manufacturing operations

All packs include double layer food grade polyethylene liner with moisture resistant sealing. Shipping. Temperature-controlled logistics and expert support for export documentation.

Delivery time: 1-3 working days after payment has been confirmed for in stock orders. Bulk orders (500kg+) will take 7-10 days including inspection of raw materials and heavy metals analysis at the end.

FAQ

Q: Why does the powder have a sulfur odor?

A: The smell is caused by the sulphur in the active sulfhydryl (-SH) group. This confirms that the substance is still in the reduced form and has full efficacy. Batches that smell like nothing are generally oxidised or otherwise deteriorated.

Q: What causes yellowing during storage?

A: Exposure to moisture or UV light causes oxidation, which leads to colour change. Keep in tightly closed, opaque containers at temperatures below 25°C to maintain the off-white appearance.

Q: Is this glutathione fermented or synthetic?

A: Our product is produced by fermentation enzymatic with Saccharomyces cerevisiae. This biological mechanism guarantees the L-configuration needed for human bio-activity, in a superior manner than chemical synthesis methods.

Q: Can you do customised specifications?

A: Yes. We may provide bespoke particle size distributions, special packaging and private label services. Specification changes are subject to minimum order quantities.

Q: Does it comply with EU heavy metal regulations?

A: Each batch is ICP-MS tested and certified to contain ≤ 10 ppm total heavy metals, in compliance with EU Regulation 2015/1005 and US FDA requirements for dietary supplement ingredients.
