Chelation therapy products, including EDTA, are agents that bind to heavy metals in the body, allowing them to pass through the body faster.

Chelation therapy products are available via prescription. Prescription products are approved for conditions such as heavy metal toxicity and very high calcium levels. Some companies also sell chelation therapy products as supplements. DMSA (2,3-Dimercaptosuccinic Acid), DMPS (2,3-Dimercaptopropane-1-Sulfonate), and EDTA (ethylenediamene tetraacetic acid) are the chemicals most often sold this way.

People use non-prescription chelation therapy products for Alzheimer disease, arsenic poisoning, autism, ADHD, Parkinson disease, and many other conditions, but there is no good scientific evidence to support these uses. Non-prescription chelation therapy products might also be unsafe.

The FDA warns consumers to be wary of non-prescription chelation therapy products marketed for the treatment or prevention of any disease. These products have not been approved or reviewed by the FDA and can cause serious adverse effects. Discuss the use of prescription chelation therapy products with a healthcare provider.
