Microcrystaline hydroxyapatite-calcium (MCH-Cal) research

Calcium is perhaps the most well known and most commonly taken supplements. MCH-Cal is a unique calcium supplement in that it is derived from whole bone and contains an organic and inorganic component. The organic component consists of collagen, glycosaminoglycans, peptides, and growth factors for bone. The inorganic component contains predominately calcium and phosphorus. Research suggests that MCHC is the best source for calcium to help maintain normal bone density (1-4).

Bone health requires the anti-inflammatory diet and additional supplements, such as vitamin D, vitamin K, magnesium, and omega-3 fatty acids. Thus, it is best to take Osatate-Calcium Complex with either the Basic or Advanced Health Promotion supplement program.
