OEM Track 1: Solid Dosage Forms (Capsules, Hard-gel, & Tablets)

Engineered with optimized bulk density (0.40 - 0.65 g/mL) to guarantee high-speed capsule filling performance and tablet compression without picking or capping.

Direct Factory Advantage: Customized mesh size (from 80 mesh to 200 micro-fine mesh) available to match your specific machinery parameters.

OEM Track 2: Ready-to-Drink (RTD) Beverages & Liquid Beauty Shots

Our water-soluble YEG-EX-SOL grade resolves thermal degradation during pasteurization and eliminates cloudy precipitation in liquid formulations.

Direct Factory Advantage: Advanced deodorization ensures your final beverage profile remains fresh, fruit-forward, and free of sulfur off-notes.

OEM Track 3: Powder Mix Sachets, Gummies & Chewable Tablets

Provides high thermal tolerance during gummy cooking and extrusion processes, avoiding active destruction while blending seamlessly into pectin/gelatin bases.

Direct Factory Advantage: Low moisture levels prevent gummy degradation, sweating, or active clumping during warehouse storage.

Case Study 1: Solving Off-Flavor & Cloudiness in European Nutricosmetic Shots

Client Pain Point: A contract manufacturer in Germany faced product rejections due to severe sulfur odors and liquid cloudiness using synthetic glutathione powder in a 25ml beauty shot.

Manufacturer Solution: We supplied our de-odored, 100% water-soluble YEG-EX-SOL grade, assisting their team with pH stabilization to maintain solution clarity during flash pasteurization.

✓ Commercial Outcome: Reached full sensory approval, resulting in an initial 5-metric-ton bulk order and seamless EU retail expansion.

Case Study 2: Preventing Capsule Discoloration & Active Potency Drop in Southeast Asia

Client Pain Point: A supplement brand in Bangkok suffered from severe capsule browning and a 20% active GSH potency loss under humid ambient warehouse conditions.

Manufacturer Solution: We transitioned them to our high-potency YEG-EX-GSH50 (Moisture ≤ 3.5%) shipped in double-vacuum aluminum foil drums, and provided guidance on nitrogen-flushed capsule packaging.

✓ Commercial Outcome: Product shelf life was successfully extended to 24 months with zero visual discoloration or active drop.

Bulk orders are packed in heavy-duty 25kg fiber drums lined with double vacuum-sealed aluminum foil inner bags. Pilot R&D orders are supplied in 1kg foil pouches with nitrogen purging to prevent oxidation during transit.

Store in sealed original packaging under cool (≤ 20°C), dry (≤ 45% RH) conditions. When stored correctly, our powder maintains a re-test period and shelf-life of 24 months with guaranteed active retention.

All shipments are dispatched with full regulatory dossiers: Batch Certificate of Analysis (COA), HPLC Chromatograms, Heavy Metal ICP-MS reports, Allergen Declarations, Non-GMO Statements, and MSDS safety sheets.

Chemical synthetic glutathione often involves toxic organic solvents (e.g., monochloroacetic acid) and faces strict regulatory bans in natural food/supplement categories in Europe and North America. Our yeast-derived glutathione is 100% bio-fermented from non-GMO Saccharomyces cerevisiae, offering full natural compliance, superior oral bio-compatibility, and clean-label acceptance.

We employ a patented multi-stage membrane separation and continuous vacuum deodorization process during liquid extraction. This selectively removes volatile low-molecular-weight sulfur compounds and free amino acids responsible for off-odors, delivering a clean, neutral-tasting powder ideal for beverages and chewables.

Oxidation occurs when GSH is exposed to moisture, heat, and oxygen. Our factory utilizes nitrogen-blanketed low-temperature spray drying and packs the powder under vacuum in double aluminum foil bags. We also control moisture content strictly below 5.0%, ensuring long-term active stability.

We quantify L-Glutathione using High-Performance Liquid Chromatography (HPLC) according to standard USP/EP pharmacopeial monographs. Unlike standard iodometric titration (which can be falsified by other reducing agents), HPLC accurately differentiates Reduced GSH from Oxidized GSSG and other peptides.

Our standard commercial MOQ is 25kg (1 fiber drum). However, we provide 100g to 1kg nitrogen-purged pilot sample kits for client R&D testing. Standard inventory grades dispatch within 3-5 business days, while custom particle size or specification orders require 10-14 days.

Yes, as a direct manufacturer, we offer full OEM/ODM customization. We can adjust GSH active percentages (from 8% to 50%), modify powder mesh size for high-speed tableting, and provide private-label drum packaging or pre-blended premixes upon request.
