Potassium is a necessary mineral for fluid and electrolyte balance, as well as cardiovascular and cellular health.

Cardiovascular function is dependent on it. Potassium stimulates numerous enzymatic reactions and is needed for a variety of physiological processes, including nerve transmission, cardiac smoothness, skeletal muscle contraction, gastric secretion, renal function, tissue synthesis, and carbohydrate metabolism. Potassium is the most abundant cation in intracellular fluid and is required for the cell's acid-alkaline balance, isotonicity, and electrodynamic properties. It also acts with sodium to maintain a healthy water balance, heart rhythm, and nerve and muscle function.
