Potassium is an essential mineral that is involved in both electrical and cellular functions.
Although it is a mineral, in the body it is classified as an electrolyte. It is the primary electrolyte found in intracellular fluid. Potassium is an important factor in the regulation of water balance, acid-base levels and blood pressure. It plays a vital role in the transmission of nerve impulses and the building of muscle tissue. It is also required for carbohydrate and protein metabolism.
