Hello, healthycure,
I don't know id you're still looking for the answer to this question about Iodine for someone with hyperthyroidism, but I recently watched Dr Sherry Tenpenney on youtube explaining details of how Iodine works in the body, including regarding hyperthyroidism. If you don't want to watch the whole thing I think you could start at minute 14, but the whole thing is worth watching. YOu can find it on youtube by typing in her name plus iodine.
