Phosphate Salts


What is it? Phosphate salts refers to many different combinations of the chemical phosphate with salts and minerals. Foods high in phosphate include dairy products, whole grain cereals, nuts, and certain meats. Phosphates found in dairy products and meats seem to be more easily absorbed by the body than phosphates found in cereal grains. Cola drinks contain a lot of phosphate - so much, in fact, that they can cause too much phosphate in the blood.

People use phosphate salts for medicine. Be careful not to confuse phosphate salts with substances such as organophosphates, which are very poisonous.

Phosphate salts are most commonly used for bowel cleansing, low blood levels of phosphate, constipation, high blood levels of calcium, and heartburn.
