TSH going up when taking Iodine can be expected because the brain is stimulating the body to make more sodium Iodide symporters (NIS)…. but we have to recognize that this is not a bad thing. More details: http://iodineresearch.com/orthoflechas.html

In almost everyone, the TSH will go up while on iodine. TSH (thyroid stimulating hormone) increases the activity of the Sodium-Iodine Symporter (NIS) that drives Iodine into the thyroid and into the cells of the other organs. That is the reason that the TSH blood levels increase when patients are taking Iodine — the TSH is needed to drive iodine into the cells.
