I have had an independent blood test done for thyroid. I have been taking65mg of Nature-Throid daily but stopped 5 days before the test. I felt very agitated and tired when I was not taken it. I wanted a result that did not have added medication. These are the results. THYROID STIMULATION HORMONE 2.68. Free THYROXINE 14.1 TOTAL THYROXINE T4 84.0 FREE T3 5.7 THYROGLOBULIN ANTIBODIES <10 THROIDPEROXIDASE ANTIBODIES 12.7 . Results they say are normal. What I cant understand is when I take Nature-Throid every day I am so calm and lots more energy. Can anyone put light on this please ,I don't want to stop the Nature-Throid. Thank you .
