Description

Phosphates are used as dietary supplements for patients who are unable to get enough phosphorus in their regular diet, usually because of certain illnesses or diseases. Phosphate is the drug form (salt) of phosphorus. Some phosphates are used to make the urine more acid, which helps treat certain urinary tract infections. Some phosphates are used to prevent the formation of calcium stones in the urinary tract.

Injectable phosphates are to be administered only by or under the supervision of your health care professional. Some of these oral preparations are available only with a prescription. Others are available without a prescription; however, your health care professional may have special instructions on the proper dose of this medicine for your medical condition.

Importance of Diet

The best dietary sources of phosphorus include dairy products, meat, poultry, fish, and cereal products.

The daily amount of phosphorus needed is defined in several different ways.

For U.S.—
• Recommended Dietary Allowances (RDAs) are the amount of vitamins and minerals needed to provide for adequate nutrition in most healthy persons. RDAs for a given nutrient may vary depending on a person's age, sex, and physical condition (e.g., pregnancy).
• Daily Values (DVs) are used on food and dietary supplement labels to indicate the percent of the recommended daily amount of each nutrient that a serving provides. DV replaces the previous designation of United States Recommended Daily Allowances (USRDAs).

For Canada—
• Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein needed to provide adequate nutrition and lessen the risk of chronic disease.

Normal daily recommended intakes for phosphorus are generally defined as follows:

Persons	U.S. (mg)	Canada (mg)
Infants and children Birth to 3 years of age	300-800	150-350
4 to 6 years of age	800	400
