PROBLEM TO BE SOLVED: To provide a method for preparing highly compactable calcium carbonate granulations useful in pharmaceutical and nutraceutical tableting.

SOLUTION: The calcium carbonate granulations are provided by mixing a composition comprising calcium carbonate in a mixer capable of creating high shear and drying the composition in a convection drying oven. Additional improvements in compactability are obtained by employing formulations comprising powdered compositions of small median particle size. Further, improvements are obtained by employing formulations comprising two or more powdered compositions of differing median particle size.
