Potassium

(Potassium phosphate)

Potassium works with sodium to regulate the body's water balance and normalize heart rhythms. Potassium is also necessary for good muscle contraction and rapid transmission of nerve impulses throughout the body. Low potassium intake may play a role in causing high blood pressure; therefore, people who are unable to reduce their sodium intake may help prevent and treat hypertension by increasing the potassium in their diets (Journal of the American Medical Association, May 28, 1997).
