Calfos is the product name for Sonac’s hydroxy-apatite. It is produced from animal bones that have been crushed and degreased. The bone chips are further processed by a heat-and-pressure treatment (110 ºC for 20 min.). The gelatin is removed to a large extent and the remainder is dried and finely ground to improve the digestibility. This is the product named Calfos.
