Direct-compression granules

Made by dry roll compaction: powder fully compressed between rolls and sized into granules. No binder, no additive: nothing in the granule but the monograph substance.

Grades

MgCO₃Magnesium carbonate granules

Roll-compacted MgCO₃ granules for DC antacid and supplement formulations; compressibility without a binder on the label.

MgOMagnesium oxide granules

Roll-compacted MgO granules for direct-compression magnesium tablets and high-load formulations; improved flow, controlled density, dust-free handling.

Mg(OH)₂Magnesium hydroxide granules

Roll-compacted Mg(OH)₂ granules for chewable antacid and DC formulations; monograph-pure and binder-free.

Applications

Direct compression — magnesium supplement and antacid tablets without wet granulation and without a binder in the formulation.

Clean label — the granule is the monograph substance and nothing else; simplifies your excipient risk assessment.

Processing — dust-free handling, consistent die filling, controlled density for high-load formulations.
