Phosphorus works with calcium and vitamin D in your body to keep your bones healthy and strong.To do this, your body’s phosphorus, calcium and vitamin D all need to be in balance.

When you have too much phosphorus in your blood, it causes your body to pull calcium from your bones to try and keep your blood balanced. This can cause your bones to become weak and unhealthy. Unhealthy bones put you at higher risk of breaks (fractures) and other problems.
