thats true for sure. Vegans and Vegetarians r even more likely to develope problems. But i now believe as well that nobody on a "normal diet" without supplementing is really Iodine sufficient.
i m taking iodoral now. Iodized salt is useless. The Iodine in it is vaporized soon after opening hte package. On top of that its refined salt which is like poison. And on TOP of that...they add weird stuff to make it dry.
