What does phosphorus do to the human body?

About 85% of the body’s phosphorus is in bones and teeth. Phosphorous is also present in smaller amounts in cells and tissues throughout the body. Phosphorus helps filter out waste in the kidneys and plays an essential role in how the body stores and uses energy. It also helps reduce muscle pain after a workout.
