Potassium The Regulating Mineral
Potassium is an important mineral in the human body. Some of its most important functions include regulating blood pressure, maintaining proper muscle function, promoting a regular heartbeat, maintaining the proper balance of water in muscle and fat tissue, and regulating the function of cells in the body.
Maintaining proper levels of potassium is important, as a potassium imbalance can lead to serious health consequences. Potassium is an especially important mineral for both serious and casual athletes, since excessive perspiration can easily deplete the body’s supply of potassium.

Supplements Those on a serious (or not to serious) exercise program often need to supplement because water lost through sweat can cause potassium levels to drop. Alcohol, caffeine and other diuretics can enhance this effect and lead to the need for still more potassium. Supplements should be stored in a location that is dark and cool.
