I did a lot of reading, and, even though the detoxified Iodine from Cayceconcepts is a little more expensive (and I usually shy away from that) I felt in my "gut" IT what was right for me. I will be purchasing a large case of it eventually - I'm that happy with it - and - it's only $5 per bottle that way.
Can't explain it. I "just KNEW" it was the right stuff.
