WebCalcium is an electrolyte, which means it has a positive charge when it’s dissolved in water. Your body uses ions (atoms with an electrical charge) in electrolytes to transport things into and out of your cells. Your body is always working to balance things out. That means when calcium ions enter a cell, sodium ions leave, and vice versa.
