I was wondering if anyone here has tried both Thyroid-S and some other brand(s) of NDT, and noticed a difference in FT levels...?
I am asking because on Thyroid-S, my FTs tend to be rather low...or rather, my FT4 levels are really low (just above the normal lower limit), while my FT3 levels are midrange, 24 hours after latest dose. I recently read an article where it was stated that Thyroid-S (this article compared it to the two other Thai brands of NDT, Thiroyd and TR TMan) contains a substance causing it to release hormones more slowly into the bloodstream, and this in turn would result in a more stable delivery of thyroid hormones over several hours. I guess this could be interpreted to mean that FT3 levels won't peak and then fall just as rapidly.
It is possibly a good thing that FT3 levels are not out of range when you go to the lab, as that tends to cause most doctors to freak out. However, like any other drug containing T3 (and I have tried both synthetic combo drug Novothyral as well as Armour and Erfa), Thyroid-S suppresses my TSH completely (<0.01). That must mean that it is working on some level (at least that is my understanding...).
I am curious if anyone else has experienced this and, if so, how do you feel on Thyroid-S compared to other brands?
