Wow this definitely a different side of the story! I was under the impression that iodine was a nutrient that our body made and needed and that if youre low on it, it can help with all kinds of things. When I took it i felt amazing. Why is this? I literally havnt felt that good in 20 years. Social angst gone, focus better, and overall sense of energy and well being. That is of course until the chest tightness. But even this morning i felt good; I felt AMAZING! I read/heard that the Lugols is cleaning and eliminating toxins like fluoride, chlorine and bromide and the symptoms are not from the Iodine but that its from the toxins being eliminated. Well, I appreciate the response as I didnt know some stuff you brought up. Just so crazy these days, you just cant trust anyone
