I never said that iodine was not an important thing for good health. I did say that too much iodine is just as bad as too little. Also that, until you have a medical diagnosis of a deficiency, supplementing based on an internet "doc's" recommendation is foolish because you could end up with too much and trash your thyroid. Vague symptoms such as "feeling tired" are not a basis for a diagnosis.
I get all the iodine I need from seafood and sea veggies. Please don't start ranting about how they are TAINTED, yada, yada. It's simply not true. That scare tactic is pushed by the people who want you to buy their "pure" iodine supplements. I prefer to get my nutrition from my food, not from pill bottles.
If someone suspects they may be deficient, they should see a real doctor, get some real bloodwork done and find out. If they really do have a deficiency, they can supplement any way they like. It's the self-diagnosis and self-experimentation with what can be a lethal substance if overdone that I find problematic.
