The Missouri Department of Health and Senior Services received information regarding a recall of Thorne Research's Captomer and Captomer-250, marketed as dietary supplements for heavy metal toxicity and heavy metal chelation therapy. The products list DMSA (meso-2, 3-dimercaptosuccinic acid), as an active ingredient, which is contained in an FDA-approved prescription product indicated for the treatment of lead poisoning in children.

FDA advises consumers to avoid all products offered over-the-counter (OTC) for chelation or detoxification. There are no FDA-approved OTC chelation products.

Procedures involving chelation agents carry significant risks and should be performed only under medical supervision.
