Thanks for you response. You have noticed increased goiter related problems in your own case with higher dose iodine, or or noticed same when surveying many cases? in other words are you speaking as a patient or as a health professional? Just curious. No, I have not recently tried the dose you suggest. My thyroid hormone levels need to be redone. I think my goiter may be multi-nodal. Last scan was inconclusive and that needs to be re-done, too.
