Di-calcium phosphate is an ionic salt, which means that it is made up of charged particles of calcium and phosphate, both of which humans need in their diet. Di-calcium phosphate is added to foods as a source of calcium, even though it has a lower percentage of calcium than the more familiar chemical, tri-calcium phosphate, which is also used as a calcium supplement (commonly in the form of calcium pills).
Di-calcium phosphate is used as a dietary supplement in foods such as prepared breakfast cereals, dog treats, enriched flour, and noodle products. This chemical is even added to some foods as an anti-caking agent because the dry form of di-calcium forms a salt-hydrate with water and then keeps the food fresh by removing water that causes the food to go stale. Di-calcium phosphate helps to preserve organic products that might otherwise break down and lose integrity over time.
If inhaled, di-calcium phosphate can irritate the lungs and cause sneezing and/or coughing. It may also irritate the skin if touched. If you are thinking about taking di-calcium supplements, consult your doctor first because di-calcium may cause adverse affects when taken with other medications.
