What Is Oral Chelation?
The Food and Drug Administration approves the use of intravenous chelation therapy, using calcium-disodium ethylenediaminetetraacetic acid (or EDTA), for the treatment of lead poisoning. Recently, some patients are choosing oral chelation, a newer and less-researched alternative, in hopes of achieving similar results or eliminating other heavy metals from the body.-
Chelation Defined
-
Chelation therapy involves the use of chelating agents--chemicals that "grab" heavy metal particles--to enable their removal.
Theories
-
Over-the-counter nutritional supplements, such as alpha-lipoic acid (ALA), cysteine and EDTA have chelating effects, and may help to flush heavy metals out of the body when taken orally.
Effects
-
No peer-reviewed trials have documented the effects of oral chelation. Intravenous chelation therapy is controversially used to treat heavy metal poisoning, heart disease, autism and other disorders.
Safety
-
Oral chelation therapy is not endorsed by the FDA, and intravenous chelation therapy is only considered safe for the treatment of medically diagnosed heavy metal poisoning.
Potential Hazards
-
Orally administered amino acids like ALA and cysteine are considered safe. However, self-diagnosis and self-treatment of heavy metal poisoning can be dangerous because patients may fail to seek medical attention for serious complications.
