How Does Chelation Work?

Chelation comes from the Greek word "claw," meaning "to grab," and that's exactly what chelating agents do. Chelating agents like EDTA travel through the bloodstream "grabbing" on to minerals and metals, such as calcium, lead, mercury, cadmium, copper, aluminum and iron, binding them, removing them from the bloodstream, and delivering them to the kidneys, which excrete them in the urine. Once bound by a chelating agent, the minerals are unable to react in undesirable ways.

The primary use of chelation therapy today is in the prevention and treatment of occlusive vascular disease, including atherosclerosis, coronary heart disease, and stroke. How does EDTA accomplish this remarkable feat? There appear to be several mechanisms involved.
