Potassium
Potassium is a metallic chemical element that is abundant in the Earth’s crust. Its salts are found in seawater. It is a part of soil rocks and minerals. Most potassium minerals are insoluble and the metal is obtained from them only with great difficulty. Potassium is the third most abundant mineral nutrient in the human body, surpassed only by calcium and phosphorus. It is extremely important electrolyte that functions in the maintenance of water balance and distribution, acid-base balance, muscle and nerve cell function, heart and kidney function. About 95 per cent of the body’s potassium is in cells.
