Now I'm really confused. Just got another batch of blood work done, and my TSH was 1.8. While "normal range" is .7-4.5, doctors are finally now admitting that any patient with a TSH level above 2 should be tested for hypothyroid condition. All my other T3, T4, free T3 & free T4 levels were perfectly fine. Yet, my body temperature is still 97.3. So, on paper, I look good, but still am running cold.... So, at what point do I chuck the natural deactiviated bovine thyroid I've been doing and start taking the hard stuff (Armour)? Any thoughts? I eat iodine rich seaweeds as well as its in my daily multi.
