Re: Hashi's- Adequate iodine intake – the good far outweighs the bad

This may explain the elevated TSH found resulting from Iodine supplementation. From iodine4health Flechas and orthoiodosupplementation in a primary care practice.

“Following orthoiodosupplementation, serum T4 and TSH levels usually go down and free T3 stays steady. I have seen TSH sometimes go up rather than down while T4 and free T3 did not change or may have gone up some. This does not mean that the patient was developing hypothyroidism but that the brain was stimulating the body to make more sodium Iodide symporters (NIS)…. While taking iodide, one may see an elevated TSH but we have to recognize that this is not a bad thing. TSH has many actions outside the thyroid that have been discovered…. Often a check of the patient’s T4, free T3 and TSH shows the T4 to go down, free T3 going down and TSH going up. Iodide is an essential nutrient that is absorbed by all cell lines. Its highest concentration is seen in the thyroid.”

So probably not unusual that the study above showed raised TSH. However, instead of seeing this as an indicator that Iodine is causing hypo it appears to be a natural response to Iodine in an attempt to stimulate production of more NIS symporters. Dr. Flechas reiterated to me over the phone that the raised TSH is transitory and usually lasts no longer than 6-12 monts.
