Quality Control

Our Eicosapentaenoic Acid is produced and tested under a strict quality management system. Each batch is analyzed to meet high-purity standards, typically exceeding 90% EPA content, with comprehensive testing for key parameters such as peroxide value, anisidine value, and heavy metals. We support compliance with cGMP, ISO, and relevant food/pharmaceutical guidelines. A detailed Certificate of Analysis (COA) is provided with every shipment to ensure full traceability and specification conformance.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen) at 2-8°C (refrigerated) or below -20°C for extended periods. The product is easily oxidized; avoid exposure to heat, air, and moisture. Keep the container sealed and handle in a controlled environment to maintain purity.
