  • Patent number: 8859011
    Abstract: Compositions comprising calcium carbonate and processes for making such compositions are provided. The invention provides a granulation comprising about 95% to about 99% by weight calcium carbonate, about 0.5% to about 5% by weight of a binder and about 0.03% to about 3% by weight of a porosity increasing agent. A pharmaceutical or nutritional composition prepared from such a granulation comprises about 90% to about 99% by weight calcium carbonate, about 0.03% to about 3% by weight of a porosity increasing agent, and about 1% to about 10% by weight of other excipients.
