i have heard just about enough. a person would have to deliberately try to take too much iodine, and even then only with much effort focused on that goal would he come close to succeeding. your deliberate wording here gives the wrong impression about iodine. "overdosing" on Iodine is about the equivalent of "overdosing" on water or chocolate. yea, you can get too much. yea, it can do a degree of harm at those levels. i would put water more risky than iodine, and certainly more life threatening when abused. we have examples of healthy adults dying from too much water. i have not seen one such case documented for iodine.
take it to the debate forum and see if someone else bites on that crap.
