The amount of conflicting information "out there" is a bit overwhelming. Who do we trust?
James, what would you consider too large of a dose?
I had been eating according to the Primal Blueprint for about 6 months before I started iodine supplements. My cycles regulated and my menstrual pain almost entirely disappeared only after I started the iodine. I take 6mg per day (unless I forget). My TSH was high at my last thyroid hormone check, but that could be because my dose was too low. Does iodine react directly with T4 or the TSH secretion mechanism in the absence of a thyroid gland?
I'm thinking of stopping the supplement for a month or two to see what happens, as a self-experiment.
