I cured my hypo-T with Iodine and co-supplements. I was on 137 mcg T4 and 18 mcg T3 for 15 years. I felt horrible.
My body temperature used to be 36,5 degrees celcius (that is 97.7 F) (the whole day by the way, not just in the morning and that was ON THE MEDS!!). It is now 37,4 degrees celcius (that is 99.3 F).
It took me about two months of iodine/iodide to get off the medication, but was still feeling horrible because of severe detox and because things were just not working properly in my body anymore. I started in october of last year. It is now october again. I'm feeling so much better now, that I'm confident to say that my thyroid and adrenals are working again. Things are not normal yet, but I'm definitely getting there.
I use Iodoral, paint with Lugols and also take Lugols internally, and take SSKI . I use quite a lot of Iodine and iodide. 1 gram of Iodide per day and 50 mg iodoral.
I have a blockage in my Iodine absorption, so I take a lot of B2 and B3 too (Optimox).
My health is improving in leaps and bounds, because of the detox which is severe at times.
I also have fibrocystic breasts, getting better fast now I'm taking enough B2 and B3.
Dr. Brownsteins book "Iodine. Why you need it, why you can't live without it" explains what you need, why you need it and also some of the chemistry behind it.
The tests that the doctors use are useless: my test results were always perfect, but I felt horribly sick. Take your morning temp instead.
Good luck! Tell us your story please. How long have you been hypo-T? What meds are you taking?
