Do Heavy Metal Detox Products Work?
The FDA says there is no proof they do. It says consumers who use over-the-counter chelation products for detoxification are exposed to all the risks associated with chelation, and that those risks are not acceptable given that there is no proof that detoxification using these products is effective to prevent or treat any condition or disease.
Chelation is a real medical treatment, but by prescription. The FDA says chelation uses certain chemicals to remove heavy metals from the body and has been used in medicine to treat metal poisoning, that all FDA-approved chelation products require a prescription because they can only be used safely under the supervision of a healthcare practitioner, and that it has never approved any chelation product for over-the-counter use. It says some of these products are marketed as dietary supplements but are in fact unapproved new drugs, and that chelation can result in serious side effects such as dehydration, kidney failure and death.
The FDA also warns about the tests sold alongside them. It says many companies that received warning letters for these products also promote home test kits to diagnose metal and other environmental toxicities, and that the kits are not cleared by the FDA and may offer false or misleading results. In 2014 it warned consumers not to buy or use Thorne Research’s Captomer and Captomer-250, marketed as dietary supplements for heavy metal toxicity and chelation therapy, and said the company had agreed to voluntarily recall them.
