Let's see you don't like seaweed, don't take kelp. Is seafood off the menu? No problem I'll be at the sushi house eating your share

You stopped taking iodine and now your TSH is dropping.

I have read that TSH has another function besides thyroid hormone production. It helps to stimulate the body's production of iodine transport cells (sodium-iodide symporter - NIS) Without adequate NIS iodine would not be able to enter the cells and be utilized.

An iodine-deficient patient's body does not require a large amount of NIS since there is little iodine that needs to be transported into the cells.

When this patient supplements with iodine, the extra iodine needs to be transported into the cells. One way the body accomplishes this is to increase TSH to stimulate more NIS.

When is the last time you had your iodine levels checked?
