Reddit mentions of The Thyroid Solution

I didn't notice a difference in that respect, but there is a plausible mechanism. The high T3 content of Armour tends to suppress the thyroid more. I like Armour better than levothyroxine alone, but I feel better taking about half and half of both (under my endocrinologist's supervision).

I had more swings after having had iodine in a contrast agent for a heart scan. My endocrinologist told me that this would happen but that there was nothing to be done about it. He told me that I and all of my blood relatives should try to consume no more than 100% of the RDA for iodine each day, adding up the high iodine content of milk, multivitamin pills, iodized salt, and oversalted restraurant food and prepared food made with iodized salt (easy to get the five times the recommended daily intake each day that way). He said that overdoing iodine intake increases the thyroid's attempts to work, and as a result increases the autoimmune attack on the thyroid. See The Thyroid Solution.
