What are the thyroid tests you had done, and the reference ranges? What is 'normal' range for one lab, or dr; may not be for another. Check out the 'Stop the thyroid madness' website. I've only briefly skimmed through it, but it seemed to be pretty helpful. Supplementing with too much iodine may actually cause thyroid problems from what I've read, so check into that before you do to be sure.
