In the realm of food and supplements, there are many ingredients and additives that serve essential roles, often going unnoticed by consumers. One such compound is dicalcium phosphate, a mineral that plays a crucial role in various industries, including food production, animal nutrition, and pharmaceuticals. In this blog post, we will explore what dicalcium phosphate is, its uses, benefits, and its significance in these diverse sectors.

What Is Dicalcium Phosphate?

Dicalcium phosphate (DCP) is a chemical compound composed of two calcium ions and one phosphate ion. It is commonly found in nature as a mineral called “brushite” and is also synthesized for various industrial applications. DCP exists in several forms, including dihydrate and anhydrous, each with distinct properties and applications.

Key Uses And Benefits:

Food and Beverage Industry:

  • Food Additive: DCP is often used as a food additive, primarily as a source of calcium, an essential mineral for human health. It is found in a range of food products, including baked goods, dairy substitutes, and fortified cereals.
  • Buffering Agent: DCP can act as a buffering agent in food and beverages, helping to stabilize the pH levels and maintain the desired texture and consistency of products like canned goods and soft drinks.

Animal Nutrition:

  • Livestock Feed: DCP is a valuable component of animal feed formulations, providing essential calcium and phosphorus for bone development, milk production in dairy animals, and overall growth and health in livestock.
  • Pet Food: It is also used in the manufacture of pet food to ensure pets receive the necessary calcium and phosphorus for healthy bones and teeth.


  • Medicine Production: In the pharmaceutical industry, DCP serves as a common excipient (inactive ingredient) in tablet and capsule formulations, aiding in the binding and disintegration of pills.
  • Nutritional Supplements: DCP is often used in the production of calcium and phosphorus supplements, contributing to the dietary needs of individuals with deficiencies or special dietary requirements.


  • Agricultural Use: DCP can be utilized as a source of phosphorus in fertilizers, enhancing plant growth and crop yield. It provides essential nutrients for soil fertility and plant health.


  • Toothpaste: In dental care products like toothpaste, DCP may be added to aid in the remineralization of tooth enamel, promoting oral health and cavity prevention.

Safety And Regulation

Dicalcium phosphate is generally recognized as safe (GRAS) when used in accordance with established safety guidelines and within prescribed limits. Regulatory bodies such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have established guidelines for its use in food and supplements to ensure consumer safety.


Dicalcium phosphate, though often overlooked, is a versatile and essential compound that plays a critical role in various industries. From fortifying food products and enhancing animal nutrition to contributing to pharmaceutical formulations and supporting agricultural growth, DCP’s wide-ranging applications are a testament to its importance in modern life. Whether it’s as a source of essential minerals or as a stabilizing agent, dicalcium phosphate quietly contributes to the health and well-being of both humans and animals while also aiding in the production of quality products across multiple sectors.


Is Dicalcium Phosphate Good Or Bad For You?

A very important property of Dicalcium Phosphate is that it is not harmful to humans. Therefore, the substance has been approved for use in food production by many institutions responsible for food safety. Dicalcium Phosphate is used in food production because of its many unique properties.

What Does Dicalcium Phosphate Do?

Dibasic calcium phosphate is mainly used as a dietary supplement in prepared breakfast cereals, dog treats, enriched flour, and noodle products. It is also used as a tableting agent in some pharmaceutical preparations, including some products meant to eliminate body odor.

What Is Dicalcium Phosphate Made From?

A synthetic source of calcium and phosphorus. Obtained by processing rock phosphates into phosphoric acid, which is then reacted with calcium carbonate (limestone). Commonly used source of calcium and phosphorus in livestock, horse, and poultry feeds.

Is Dicalcium Phosphate Natural?

Dicalcium phosphate is usually synthetic, but there are some small, limited deposits from natural sources, such as monetite. Dicalcium phosphate might be obtained from roasting bones, but most bone sources of dicalcium phosphate are precipitated by using strong acids prohibited for organic production.
