right, by law the thyroid glandulars sold as supplements are thyroxine-free, so they do not act like thyroid meds. You might want to find a doc to prescribe Armour to you, as if you have clinical hypothyroid, it might be hard going off the Armour. And Armour is cheaper than most glandulars, at least if you are only taking a grain or two a day. Although, as I understand sometimes the glandulars have a stimulating effect on the thyroid anyway.
