Why does our body need potassium

The human body is very complex, completely unexplored system in which everything is clearly thought out. So far we know not so much. Including the fact that microelements play an important role in human life.

Potassium is involved in important metabolic processes, in particular - water salt metabolism at the intercellular level and protein synthesis. It is extremely necessary for the full work of the kidneys, intestines, and heart.
The minimum daily allowance of potassium for an adult is 2,000 mg.

The older the person, the greater the need. We calculate it by the formula: the above norm + the number of years.

We receive potassium from food. The following products are rich in this microelement:
