Calcium Hydroxyapatite

An organically bound calcium complex with the built-in benefits of minerals and proteins that are naturally occurring in the bone matrix

Here are the bare bones about calcium: it’s the most abundant mineral in the body. Although 98 percent of the body’s calcium is stored within the bones and teeth as calcium hydroxyapatite—where it adds density and strength—the mineral can also be found in the blood because it has other important biological functions.

About Calcium Hydroxyapatite

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

If you think you’re meeting your calcium requirements strictly through diet, consider this. If you’re lactose intolerant, vegan or avoiding dairy products for other reasons, realize that plant-based foods provide much lower amounts of calcium per serving than a glass of cow’s milk. So you’re not alone if you’re not meeting the recommended adult intake of 1200 milligrams of calcium per day.

Fortunately, there’s an easier way to fulfill your daily calcium requirements. Pure Lab Vitamins Calcium Hydroxyapatite contains more than just calcium. It’s an organically-bound complex of what’s naturally part of the bone matrix: bone growth factors, proteins, 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, calcium citrate and other popular calcium compounds, calcium hydroxyapatite supports the bone mineral matrix in its entirety. It has greater bioavailability than calcium citrate and calcium carbonate, with more of each dose absorbed into circulation.

Pure Lab Calcium Hydroxyapatite contains only high-grade, certified BSE-free Australian bovine bone meal as its source material. Each capsule contains 250 milligrams of pure elemental calcium.

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 Hydroxyapatite, the Recommended Daily Intake (RDI) of calcium can be obtained with just 1-2 capsules 2 -3 times daily with food.

If you consume milk products or calcium-fortified non-dairy milk substitutes, you may require fewer capsules to achieve your daily requirements (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.
