What is it?

Potassium is a mineral that is found in many foods and is needed for the body, especially for heart functions. Potassium, a chemical element with symbol K, is a necessary ion to sustain life. Dietary supplements of potassium are often given to patients who require additional potassium, for example, for some patients who take certain diuretics. Major potassium chemicals include potassium bitartrate, potassium hydroxide, potassium carbonate, potassium sulfate, and potassium chloride. Pure potassium appears as a silver-to-white alkali metal that will ignite if placed in water, and is usually stored in liquid paraffin.[1]
