When sodium is reabsorbed in the kidney, water and potassium are also reabsorbed, thereby maintaining ECF volume. Potassium is a key electrolyte in cellular metabolism. Calcium is responsible for bone health and neuromuscular and cardiac functions. It is also an essential factor in blood clotting. Magnesium is a mineral used in more than 300 biochemical reactions in the body.
