Mineral
Phosphorus
Phosphorus works with calcium to build strong bones and teeth and helps release energy from food. It is found in many everyday foods, so deficiency is rare.
What it is
Phosphorus is an essential mineral, most of which is stored in the bones and teeth alongside calcium.
What it does
It helps build and maintain strong bones and teeth, and is involved in releasing energy from food and in the structure of every cell.
Good sources
Found in many foods including red meat, poultry, fish, dairy products, bread, rice and oats.
Deficiency and who is at risk
Deficiency from diet is very rare because phosphorus is so widespread in food. It is usually only seen with certain medical conditions or medicines.
Balance
Can you have too much?
Very high intakes, mainly from supplements or certain additives, can affect the balance of calcium and are a concern for people with kidney disease, who may need to limit phosphorus.
