Phosphorus is a mineral that helps build strong bones and teeth. It also helps release energy from food.
Good sources of phosphorus
Phosphorus is found in:
- red meat
- dairy foods
How much phosphorus do I need?
Adults need 550mg of phosphorus a day.
You should be able to get all the phosphorus you need by eating a varied and balanced diet. If you take phosphorus supplements, it is important not to take too much because this could be harmful.
Taking 250mg or less a day of phosphorus supplements is unlikely to cause any harm.
What happens if I take too much phosphorus?
Taking high doses of phosphorus supplements for a short time can cause diarrhoea or stomach pain.
Taking high doses for a long time can reduce the amount of calcium in the body, which means bones are more likely to fracture.
