So we get many happy stories and a few sad stories, supposedly from "iodine". But is it really the Iodine that can make some people happy and others sad, or is it something else ?? How can the same Iodine have such opposite effects in people ? There is more to this picture. I'm thinking the 1/6 who report negatively may have other underlying issues and Iodine giving them a bad reaction is just a signal to them that something else is wrong. At the very least, their iodine metabolism is aloof. Finding the reason why their iodine metabolism is aloof is necessary , and its not that hard to do
