I have been using a colorless kelp iodine for several months for an enlarged and cystic thyroid. My blood tests for thyroid indicated a low level of the hormone. I used chemical replacement for a few months and felt much better, but the thyroid was still enlarged. I used 3 drops, twice a day as recomended on the bottle. The swelling stopped. I stopped taking the chemical prescription. My blood tests normal. The thyroid is still very slightly enlarged, but doesn't bother me any more.
