Quality Control

Our Magnesiumpotassiumcitrate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and composition, suitable for demanding applications. Certificates of Analysis (COA) documenting parameters such as assay, heavy metals, and microbial limits are provided with every shipment to ensure traceability and compliance.

Storage

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