Calcium Hydroxyapatite

Calcium Hydroxyapatite is a freeze-dried (cold processed) source of concentrated calcium obtained from New Zealand. This special calcium contains a 2:1 ratio of calcium to phosphorus. Our Calcium Hydroxyapatite also contains trace minerals, matrix proteins and glycosaminoglycans. Hydroxyapatite supplies calcium in the form it occurs in the body. As such, the calcium can be absorbed rapidly.

A study entitled "Treatment of Cortical Bone Therapy in PBC" (Epstein et. al.) outlined a study in which a group receiving calcium hydroxyapatite was compared with a control group receiving calcium gluconate over a period of 14 months.

Over the 14 month period there was a significant loss of cortical bone in the control group and a significant increase in cortical bone thickness in the calcium hydroxyapatite group. Patients receiving calcium hydroxyapatite had a net cortical bone gain of 11.6%. The control group (receiving calcium gluconate) showed only a net gain of 7%. The difference between 7% and 11.6% represents a gain of over 60%.

Why is calcium hydroxyapatite more readily absorbed than soluble alternatives? The study suggests that it is the result of at least three factors:

• Calcium absorption is enhanced in the presence of protein.
• Calcium absorption is enhanced by an organic matrix.
• The microcrystalline structure of calcium hydroxyapatite gives a large surface area from which the minerals may be released from the organic matrix in the intestine.

Further, calcium balance studies in patients with osteogenesis indicate that calcium hydroxyapatite produces more prolonged positive calcium balance than other soluble calcium salts.

Calcium Research Results

• Calcium, magnesium, zinc, fluoride, and phosphorous work together to form and maintain bones and teeth (Somer, 1995; Mahan et al, 1996).
• The ratio of calcium to phosphorous and calcium to magnesium are important in the absorption, use, and excretion of these minerals (Somer, 1995; Mahan et al, 1996).
• Optimal calcium absorption depends on adequate amounts of vitamin D to be available (Somer, 1995; Mahan et al, 1996).

Calcium Complex Hydoxyapatite Calcium is the microcrystalline form of calcium and phosphorus in the exact ratio formed by the body. Potassium, Magnesium, Boron, Zinc, Silica, and Chromium are also included in this powerful product. In addition, our calcium complex also contains proteoglycans, primarily chondroitin (chondroitin sulfate), gel-like substances that fill the bone matrix and transfer minerals in and out of bone tissue.
