Phosphorus is present in large quantities in our body and performs several essential functions.

What is it

Phosphorus is an element that enters the composition of teeth, bones and cells, and represents more than 1% of body weight in adults.

Food sources

Foods that contain phosphorus are cereals, vegetables, milk, beef, fish, poultry and legumes.


Phosphorus is indispensable in various energy production processes (metabolism of fatscarbohydrates and proteins) and stimulates muscle contractions; It is also necessary in communication between cells, ensures kidney function and transmission of nerve impulses.

Phosphorus (especially in the form of salts) accelerates the process of calcification of bone fractures and reduces the subsequent loss of calcium.

It is used for this reason in the treatment of osteomalacia and osteoporosis. It also helps to prevent or treat rickets.
