Chelation Therapy is a process in which a substance is used to bind molecules, such as metals or minerals, and hold them tightly so that they can be removed from the body. Chelation has been scientifically proven to rid the body of excess or toxic metals. For example, a person who has lead poisoning may be given chelation therapy in order to bind and remove lead from the body before it can cause damage.
With EDTA chelation therapy, the substance that binds and removes metals and minerals is EDTA (ethylenediaminetetraacetic acid), a synthetic amino acid that is often delivered intravenously. EDTA was first used shortly after WWII for the treatment of heavy metal poisoning. Calcium disodium EDTA chelation removes heavy metals and minerals from the blood, such as lead, iron, copper, and calcium, and is approved by the FDA for use in treating lead poisoning and toxicity from other heavy metals. Although disodium EDTA it is not approved by the FDA to treat coronary heart disease (CHD), some physicians and alternative medicine practitioners have recommended its use in chelation as a way to treat CHD.
