Or it could be the fact that 3mg of Iodine is an overdose and has caused hashimotos in the past? Destroying the thyroid gland will result in long term side effects not related to how much Iodine is currently in your system.
A better analogy would be swallowing a piece of glass, it passes through you, and is completely out of your system in days. But for some reason you still have internal bleeding weeks afterwards.
I can't believe how much damage you guys are doing over here.
