From Iodine: The Universal Nutrient: Iodine detoxifies – Mercury, Lead, Aluminum, Cadmium I take 50 mg of Iodoral every day. Initially started it for hypothyroidism and then found it had other great benefits. I spoke with a MD office who does Chelation Therapy today and also asked them about dentists/amalgams. The Chelator doc did a full spectrum of toxic metal (e.g. mercury) test pre and post therapy to see results. I asked how they worked with the dentists they referred to and how it might go with amalgam removal. They said typically best to speak to dentist first and get his input. Then pair any amalgam removal with chelation based on that.
