Chelation therapy is a treatment for heavy metal poisoning: iron, mercury, arsenic, and lead. 

The word Chelation comes from the Greek word "claw," meaning "to grab," and that's exactly what chelating agents do.

Chelating agents like Fulvic Acid 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.
