Potassium is an important mineral used in various bodily functions. It is an important factor in the maintenance of the body's acid-base balance and nerve condition, as well as the transfer of nutrients through cell membranes.

Potassium is found in a number of foods, including dairy, fish, and other meats, fruits, vegetables and whole grains. Because food processing reduces the levels of naturally occuring nutrients in foods, supplementation may be necessary to insure adequate intake.
