Magnesium Carbonate – High-Purity Mineral Salt for Excipient Applications

Magnesium Carbonate is not only a reliable Magnesium source for food supplements, but also an exceptionally versatile excipient in pharmaceutical formulations. Dr. Paul Lohmann® offers high-purity Magnesium Carbonate tailored to meet your functional and regulatory needs – from direct compression to controlled drug release.
Why Magnesium Carbonate as an Excipient?
Magnesium Carbonate brings multiple technological advantages to drug formulation processes. Its mineral structure and functional versatility make it a widely used excipient in solid dosage forms:
- Glidant – Improves powder flowability, essential for consistent dosing
- Filler / Diluent – Provides bulk in tablet and capsule formulations
- Anti-caking agent – Stabilizes powder blends in dry formulations
- pH buffer – Helps stabilize pH-sensitive APIs

Optimized for Manufacturing Efficiency
As a leading manufacturer, we offer Magnesium Carbonate in a wide range of bulk densities – from extra light to heavy grades – for tailored process optimization. Our direct compressible (DC) grades are designed for efficient tableting, reducing the need for additional processing steps.
It meets the purity requirements of Ph.Eur., USP, FCC and E 504 and is available as a white powder in various bulk densities. DC Granules are also available which are ideal for direct compression to tablets and which simplify the manufacturing process due to their free-flowing properties.
With a strong commitment to quality and regulatory compliance, we provide Magnesium Carbonate as an API, along with comprehensive documentation (CEP/DMF) for seamless registration with international authorities.
