Calcium phosphate or phosphate of lime, also known as bone ash or bone phosphate, is a common calcium supplement. It is a white powder with no odor and a slightly salty taste. It is insoluble in water and alcohol but soluble in dilute acids.

Calcium phosphate is a mineral that is found in many foods, including milk, cheese, yogurt, and dark green leafy vegetables. It is also available as a supplement in the form of tablets or capsules.

Calcium phosphate is an important nutrient for bones and teeth. It helps to strengthen bones and make them more dense, which can help to prevent fractures. It also helps to maintain healthy teeth and gums.

Other potential health benefits of calcium phosphate include:

- Reduced risk of heart disease

- Improved blood pressure control

- Reduced risk of kidney stones

- Improved muscle function

- Reduced risk of osteoporosis

- Improved sleep quality

- Reduced stress and anxiety

Calcium phosphate is generally safe to take, but some people may experience side effects such as constipation, gas, or bloating. These side effects usually go away after a few days or weeks.

If you are pregnant, breastfeeding, or have a medical condition, it is important to talk to your doctor before taking calcium phosphate.
