Accuracy is an issue here, but only in a couple of key parts. Overall this is a good overview of hypOthyroidism. Unfortunately, there is barely any mention of exercise and other non-pharmaceutical ways to boost thyroid hormone. The medications information is where I take issue unfortunately. Combination T4/T3 therapy has been proven effective and is preferred over T4 treatment alone for many patients, and Armour thyroid supplement has been proven over and over again to be one of the most consistent thyroid supplements on the market, with almost no problems. The synthetics unfortunately do not have nearly this record, tho it is better since recent reformulations. Too bad the author didn't know this.
