Calcium must pair with Magnesium

Calcium Should Not Be Taken By Itself  Those involved in nutritional medicine have long known that people who supplement with calcium should also take adequate amounts of magnesium. The reason is that magnesium is a natural calcium channel blocker.2 Magnesium deficiency can induce elevation of intracellular calcium concentrations, and accelerate atherosclerosis.3 Calcium is a component of atherosclerotic plaque and when calcium salts build up in soft tissues it causes hardening, which is technically called calcification.
