Is there anyone here that has had RA and is currently taking Thyroid-S ? I had RA about 8 years ago and have been on 125mg of Synthroid since, without any improvement. Actually I have acquired worsening of symptoms as the years go by. I'm interested to know if Thyroid-S is just a T4, T3 or a combination of both. Are you supposed to stop taking other meds like Synthroid altogether? I have researched it, but still can't find much info on it. Is Thyroid-S a NDT or is it just used as a supplement?
