Magnesium Stearate — High-Purity Excipients for Dietary Supplements

Magnesium Stearate is a widely used pharmaceutical and nutraceutical excipient that functions primarily as a lubricant and flow agent. At CSK Biotech, our Magnesium Stearate is produced to strict quality standards to ensure consistent particle size, excellent lubricity, and minimal impact on active ingredient stability. Ideal for capsules, tablets, and powdered blends, our Magnesium Stearate supports reliable manufacturing and consistent final product performance.

Product Overview — Pharmaceutical-Grade Quality

Our Magnesium Stearate is available in pharmaceutical and nutraceutical grades, manufactured under controlled conditions to meet client specifications. Each batch undergoes comprehensive testing for purity, heavy metals, microbial limits, and identity (e.g., FTIR). The result is a free-flowing, low-moisture powder optimized for high-speed tableting and encapsulation processes.

Benefits in Formulation and Manufacturing

Incorporating Magnesium Stearate into your formulations improves powder flowability, reduces ejection forces during compression, and minimizes die wear—helping to achieve uniform weight and content uniformity. Its lubricating properties enhance production efficiency and reduce downtime, making Magnesium Stearate a practical choice for large-scale supplement manufacturing.

GMP Manufacturing & Rigorous Testing

CSK Biotech produces Magnesium Stearate in a GMP-certified 2,000㎡ facility with seven advanced production lines and full QC labs. Certified by GMPC, FDA, HACCP, and ISO standards, we perform routine QC analyses—assessing particle morphology, residual solvents (if any), moisture, and microbial safety—to ensure compliance with global regulatory expectations.

Applications & Custom Solutions

Magnesium Stearate is compatible with capsules, tablets, powders, and certain softgel processes. As a full-service CDMO, CSK Biotech offers ODM, CDM, and OEM cooperation models to tailor magnesium stearate usage levels and blending protocols to your specific formulation, scale, and stability requirements.
