Introduction
Phosphorus is the second most abundant mineral in the human body and makes up about 1-1.4% of fat-free mass. [1,5,6]
It is present in every cell of the body and plays an important role in how the body uses carbs and fats.
It is also a component of the bones, teeth, DNA, and RNA. [1]
Phosphorus additives are widely used in many foods to preserve moisture or colour, or even for stabilising frozen foods. These foods naturally contain a lot more phosphorus per serving than natural food sources and play a role in maintaining the normal reserves in the body. [1]

- Normally, phosphorus absorption rates vary between 40 and 70% in the small intestine and the mineral is absorbed more efficiently from animal sources than plant sources. [1]

- 85% of phosphorus reserves are stored in bones and teeth and the remaining 15% are distributed throughout the blood and soft tissues. [1,2]
- Total body phosphorus stores in adults have been estimated to be around 400–800 g. [5]

- Excretion is through the urine and is regulated by the kidneys. [2]
- Also, faecal excretion of phosphorus is estimated to be around 300 to 600 mg/day. [5]

Groups At Risk of Phosphorous Deficiency
Phosphorous Interaction With Other Nutrients
- Calcium – Unabsorbed calcium in the digestive tract combines with phosphorous and interferes with its digestion and absorption. [2]
- Aluminium – When taken in large doses, antacids that contain aluminium may interfere with phosphorus absorption. [2]
