Well, JK98, you have a strong point here. Im also wary when it is stated they have been tested for unsafe levels of toxins, but does it say they are toxin free? So that's what scares me a little, since I used to take a product that said tested for mercury and how it did not have "unsafe" levels of mercury.

However, I noticed symptoms after I took it and had to stop. So though it was not unsafe for most normal/healthier people, for those already toxic and have a tendency to hang onto toxins, rather than readily excrete them, it may be an issue.

There are plenty of other sources to get iodine. I have it in a supplement and also have diluted lugol's iodine and it seems fine for me.
