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.
