The invention provides a process for the preparation of an orally administrable calcium composition, said process comprising the steps of: (i) obtaining a physiologically tolerable particulate calcium compound having a mean particle size in the range 3 to 40µm, having a crystalline structure and having a surface area of 0.1 to 1.2 m2/g; (ii) mixing said calcium compound with a water-soluble diluent and an aqueous solution of a water soluble binder in a fluid bed granulation apparatus and drying the resulting mixture to produce a first granulate; (iii) optionally mixing said first granulate with one or more further components to produce a second granulate; and (iv) optionally compressing said first or second granulate to form tablets.
