I asked a PhD that I know about Iodine therapy, and FWIW to any of you, this is what was sent back to me. I had a hunch this would be the tone of the reply I got.
Don't use iodine. It will severely inhibit your thyroid. It is a cult (hoax) promoted by Dr. _______ (name removed by me). Iodine deficiency is almost non-existent in this country. Especially in those who eat fish or processed foods. 150 ug (micrograms) daily is a safe dose. I have many clients who have been taking Iodine and all had to stop because they developed serious goiters and became very ill!
