Abstract: The present invention provides a composition including a particle, the particle includes a carbonate species of a first divalent metal and carbonate specie of a second divalent metal; wherein the particle is amorphous; wherein the first divalent metal and the second divalent metal are in an oxidation state of +2; and wherein the first divalent metal and the second divalent metal is each independently selected from: Ca, Zn, Fe, Cu, Co, Ni, Mn, Mg and Cr. Further provided is a composition including a divalent metal carbonate including any derivative thereof, and at least one stabilizing agent, wherein the divalent metal is selected from: Zn, Cu, Co, Mn, Mg, and Ni, optionally being characterized by BET between 20 and 200 m2/g. Pharmaceutical or nutraceutical compositions including the composition of particles disclosed, are also provided.

Abstract: The present invention provides solid compositions of amorphous calcium carbonate (ACC) and a polyphosphate, bisphosphonate or pharmaceutical salts thereof as a stabilizer. Said stabilizers stabilizes the ACC and prevent crystallization to crystalline calcium carbonate (CCC) for a long period of time, even in an aqueous suspension. The invention further provides pharmaceutical composition comprising the solid ACC compositions as well their use in treating of certain diseases and conditions.
