HydroxyCal supplies an efficient complex of nutrients and cofactors that support bone strength and maintenance. Calcium is supplied as citrate as well as in a freeze-dried, whole-bone bovine extract. This extract is also a rich source of bone matrix proteoglycans and trace minerals, and has been shown to be exceptional for supporting bone maintenance and repair. A generous amount of vitamin K is included, and vitamin D is supplied in the preferred D3 form for maximum bioavailability. These nutrients, along with vitamin C and manganese, work together to support optimal bone density and help skeletal structures maintain their integrity.*
