What is the role?

When combined with sodium, potassium has many actions in the body. Its action takes place inside nerve and muscle cells as well as in the blood.

Potassium allows the contraction of muscles, especially the heart. However, it acts on all muscles.

It acts inside the cells, in association with sodium, which acts outside the cells. This action sends nerve transmissions to the muscles, which can contract.

Therefore, it is essential for cardiovascular health. It also plays a role in protein and carbohydrates.

The level of potassium, called kalemia, must be balanced to ensure the proper functioning of the heart, muscles and kidneys.

A normal level is usually between 3.5 and 5 millimoles per liter. An excess of potassium is called hyperkalemia and a lack of potassium is called hypokalemia. An imbalance in potassium can cause more or less severe disorders.
