And even if it did, you don't have dangerous atherosclerosis until those clogs start to calcify. The interactions between calcium, magnesium, vitamin D, vitamin A, vitamin K, collagen, silicon, and boron also somehow affect this process, but the exact mechanisms are not yet fully understood by scientifically sound research. I do not know of any human studies planned or underway on the hypercalcemia hypothesis for heart disease.
The pop-science gurus claim that obstructive heart disease is primarily caused by consuming calcium in excess without attending to the other related dietary factors, and this causes the excess dietary calcium to harden arterial plaques rather than bones and teeth. They are usually pushing magnesium supplements or organic butter oil or some other purchasable product.
