Calcium Hydroxyapatite

Building Strong Foundations. Calcium Hydroxyapatite is an organically-bound complex of what’s naturally part of the bone matrix.

About Calcium Hydroxyapatite

Calcium is vital for muscle contraction in the skeletal muscles, as well as for the heart’s blood-pumping action, blood vessel contraction and vasodilation. The mineral is also involved in nerve impulse transmission and blood clotting, as well as tooth formation and maintenance.

Pure Lab Vitamins Microcrystalline Calcium Hydroxyapatite (MCHA) contains more than just calcium. It’s an organically-bound complex of what’s naturally part of the bone matrix:  bone growth factors, proteins, mucopolysaccharides, calcium, phosphorus, and trace minerals. Together, these are needed for the maintenance of healthy bones, teeth and systemic cellular functions.  

With its superior bioavailability over calcium carbonate and other popular calcium compounds, calcium hydroxyapatite supports the bone mineral matrix in its entirety.  Its natural phosphorus content is vital to the balance and utilization of vitamin D, iodine, magnesium and zinc, as well as for the production of the phosphates used in cellular membrane function, energy, and DNA.

Each capsule of Pure Lab Vitamins Calcium MCHA contains 250 milligrams of pure elemental calcium from hydroxyapatite. For your safety, it is derived from certified BSE-free Australian bovine bone meal, meaning it has been tested to be free of disease-causing prions.

Some calcium products have so little calcium per capsule that more than 6 capsules must be taken daily to achieve the desired benefits. With Pure Lab Vitamins Calcium MCHA, the Recommended Daily Intake (RDI) of calcium can be obtained with just 1-2 capsules 2 -3 times daily with food. However, it must be emphasized that those who consume milk products or calcium-fortified non-dairy milk substitutes may only require the lower end dosage of this RDI (or as advised by a health care practitioner). Be sure to consider your dietary intake of calcium when determining your individual dosing of calcium supplements.

Dairy-free diet



Bone fracture

Pre-eclampsia of pregnancy
