Tricalcium phosphate, also known as calcium phosphate, is a calcium salt with the chemical formula Ca₃(PO₄)₂. It is sometimes abbreviated as TCP and is also referred to as tribasic calcium phosphate or bone phosphate of lime (BPL). This white solid has low solubility

1. Nutritional Supplement: Tricalcium phosphate is commonly found in nutritional supplements. People may take it to supplement their daily calcium intake if they are not getting enough calcium from their diet alone. However, excessive intake can lead to side effects such as nausea and constipation.

2. Tricalcium phosphate is found in various household items, including baby powder, toothpaste, and antacids.

   • It is used in the biomedical sector to make cement or composite materials for bone repair.

3. While tricalcium phosphate is readily absorbed by the body, there is little evidence to suggest it is more effective than other calcium supplements, such as those containing citrate and carbonate
