  • Re, oldspammer's comment: 1) Hardening of the arteries is not primarily a lesion of calcium metabolism. The primary lesion is injury of the vessel lining, leading to buildup of cholesterol-containing plaques, which then rupture and clot off the artery. Calcium deposition is a secondary phenomenon that has nothing to do with blockage of the artery. 2) The claim that lowering serum calcium draws calcium out of the blood vessel walls is wholly unsubstantiated.

  • A deception? Google (chelated calcium)

    Calcification of blood vessels is known as hardening of the arteries--the process can be induced by excess PTH where excess serum calcium persists. Calcium is a metal, but not a heavy metal like lead. By lowering serum calcium for long enough time while osteoclastic & osteoblastic activity is elevated, the calcium should migrate from blood vessel walls back onto the bone where it came from.

    Chelation may be quackery but not for the reasons given in video.
