Calcium Phosphate
Calcium Phosphate occurs naturally in our tooth enamel and bones as well as some rocks, and animal bones. It is also found in many food sources including dairy products, nuts, and leafy green vegetables. Phosphate deficiency is more common in those with celiac disease, Crohn’s disease, kidney issues and may make calcium phosphate more attractive for people with these issues.

Our key metric
Price Per Absorbed Gram
This allows you to see what the true cost is for each gram of calcium that your body actually uses.

Finding calcium supplements with high bioavailability and elemental percentage lowers the size and number of pills needed to meet the recommended daily allowance (RDA). When we consider what your body absorbs some of the more inexpensive supplements may not be the bargain they appear to be. While other supplements with higher prices may be absorbed much better allowing you take fewer (or smaller) pills.

calcium carbonate facts
- The chemical formula for calcium phosphate is Ca3(PO4)2
- While our bones and teeth are comprised of Calcium Phosphate, it doesn’t necessarily mean it is the easiest form of calcium for our body to absorb.
- Sometimes is an added ingredient in toothpastes.
- Calcium Phosphate is also used in the manufacturing of fertilizers, ceramics, glass, and some metals.
- The phosphate ions in calcium phosphate likely react with hydrochloric acid in the stomach to neutralize the acid. Thus it can be used as an antacid.
Sources
- Dairy products
- Fish
- Nuts and seeds
- Leafy green vegetables
- Also be synthesized through chemical reaction of Calcium Carbonate with Phosphoric acid
Health Benefits
- development and maintenance of strong bones and teeth
- helps in the proper functioning of the heart, muscles, and nerves
- necessary for the blood clotting process
- studies have shown that a diet rich in calcium may be associated with lower body weight and a reduced risk of obesity
- calcium intake can help to prevent osteoporosis
Reactions with other Vitamins
- Vitamin D helps absorption
- Magnesium works with calcium – you need both
- Calcium can interfere with the absorption of iron and Zinc – take calcium and zinc or iron supplements at different times of the day
- may interact with blood pressure medications and blood thinners. It’s best to consult with a doctor before taking these medications and calcium supplements together.
