Quality Control

Our L-Arginine-L-Malate is produced under strict quality management systems. It is typically manufactured to meet or exceed specifications relevant for dietary supplement and pharmaceutical intermediate applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each batch to ensure transparency and traceability for our B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material 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.
