Quality Control

Our Nickel Citrate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing specific results for purity, heavy metals, and other critical parameters is provided with every shipment to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
