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 conduction, as well as the transfer of nutrients through cell membranes. Potassium is found in a number of foods, but food processing reduces the levels of naturally occurring nutrients in foods. Supplementation may be necessary to insure adequate intake.
