The body uses electricity, or the movement of mineral electrolytes (such as calcium and magnesium), to control muscle movement. The heart muscle, for example, maintains regular heartbeat through electric impulse. The contraction (tightening) and relaxation (loosening) of the heart muscle requires a balance of mineral electrolytes. This is why calcium supplementation is associated with increased risk of heart attack (Bolland, et al), because excess calcium locks the muscle in contraction (like a cramp) without sufficient magnesium to relax the muscle in the heartbeat rhythm – thus resulting in angina (heart/chest pain) or even a heart attack.

It is dangerous to attempt to manually balance our electrolyte minerals through supplements. Animal-based foods (such as the high levels of calcium in dairy) and processed foods also throw off our electrolyte balance. The best way to balance electrolytes is to eat a healthful diet of whole plant foods, and the body will naturally absorb and excrete electrolytes according to its needs to maintain proper balance.
