Calcium carbonate has a high neutralizing capacity and, thanks to its slow dissolution, the longest neutralizing action.

Bone health

Bones undergo a constant dynamic process of formation and resorption. Factors like dietary restrictions or life stages, such as pregnancy or old age, may tilt the balance in favor of bone resorption. 


Adequate calcium supplementation may be required to maintain bone health. Omya’s natural calcium carbonates offer a range of particle sizes to fit different dosage forms, whether liquid or solid.


Their high elemental calcium content (40%) allows for smaller tablets and granules, while their low carbon footprint provides a more sustainable solution for bone health products.
