Life would be impossible without potassium. Potassium is part of every cell in the body and supports muscle and brain health. Potassium is an essential mineral which works with sodium to communicate between nerve cells and enable normal muscle contractions (including the heart). This works because molecular pumps pull potassium into cells and push sodium out, creating signals along the nerves to power the contraction of muscles. Additionally, potassium and sodium help the kidneys to work properly to maintain a healthy balance of fluids in the body. Potassium also aids maintenance of normal blood pressure.

Quick Summary

Potassium works with other minerals to activate muscle contractions, maintain normal blood pressure and help regulate fluids.

Why is Potassium important?
