There are many types of iodine, and this did not work for me. I recommend you ask them first for a sample! I didn't know that was an option until I looked at their return policy to see this $43 bottle of iodine could not be returned.

This is the strongest, purest iodine I could find anywhere. I originally muscle tested 4 products & this one was the most positive (the only one worthy, actually). I'm able to get off of a lifetime of thyroid medication - with my Drs approval, including bloodtests, by taking this daily. I like it.
