Quality Control

Our R-Lipoic Acid L-Arginine is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including chiral purity verification to ensure the exclusive presence of the biologically active R-enantiomer. We provide full traceability and Certificates of Analysis (COA) confirming identity, purity, and compliance with relevant specifications for pharmaceutical and nutraceutical applications.

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 hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation and clumping. For long-term storage, consider desiccated conditions.
