Quality Control

Our Dl-Glutamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, chiral purity, and impurity profile analysis, to ensure it meets stringent specifications for pharmaceutical and food-grade applications. Certificates of Analysis (COA) confirming compliance with relevant standards such as USP, EP, and FCC are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
