Quality Control

Our Sl-Glutathione is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for pharmaceutical and nutraceutical use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is easily oxidized and should be handled under an inert atmosphere when appropriate for large-scale or prolonged operations. Keep the container tightly sealed to minimize exposure to air and moisture.
