AUDIENCE: Consumer
ISSUE: FDA is warning consumers not to purchase or to use Thorne Research’s Captomer or Captomer-250, marketed as a dietary supplement 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.

Procedures involving chelation agents carry significant risks and should be performed only under medical supervision.
The company has received several adverse event reports associated with these products. Thorne Research has agreed to voluntarily recall the products. For recall information, contact Thorne Research.
BACKGROUND: FDA-approved chelating agents are available by prescription only and are approved for use in specific indications such as lead poisoning and iron overload.
