FAQ
Q1: What’s your minimum order quantity for glutathione trial sample?
Our MOQ starts from 1kg for buyer’s lab formulation test. Free sample service is available under client bear international courier cost. Bulk formal orders can be arranged from 25kg (one drum) up to a full 20ft container.
Q2: Can you provide customized purity specification and third-party test certificate?
Yes, we support customized purity from 98.0% to 99.5% based on buyer’s formulation demand. COA, MSDS, ISO certification and third-party SGS test report are attached with every shipment document.
Q3: What’s the difference between fermented glutathione and chemical synthetic glutathione?
Yeast fermented glutathione has no harmful solvent residue, higher biological activity, suitable for pharma injection grade production. Synthetic type owns lower cost but residual chemical impurity, mostly limited to low-end cosmetic raw material only.
Q4: How to avoid glutathione powder yellowing during storage and transportation?
Our factory uses double-layer aluminum vacuum inner bag plus fiber drum outer package. We advise clients to store raw stock under cold storage condition and keep packaging sealed once opened.
Q5: Do you accept OEM customized packaging for private label bulk glutathione?
We support private label drum packaging service for bulk wholesale clients. Minimum customized packaging order is 500kg, and the production cycle is 7 working days after artwork confirmation.
Q6: Which countries have your regular bulk glutathione export business?
Our main export markets include USA, Canada, Germany, UK, Australia, Malaysia and Indonesia, with complete customs clearance document for raw material import registration in above regions.

Storage Recommendations for Reduced Glutathione
Reduced glutathione is sensitive to oxygen, moisture and elevated temperatures. Improper storage may accelerate oxidation and convert active GSH into oxidized glutathione (GSSG), reducing product effectiveness.
- Store at 2℃–8℃ under refrigeration.
- Keep container tightly sealed after opening.
- Avoid direct sunlight and moisture exposure.
- Recommended shelf life: up to 24 months under refrigerated storage.
