Synthetic T3 20mg

Posted , 4 users are following.


Just wondered if anyone is currently taking T3 alongside Levothyroxine. I am currently on 175mg but my endo is going to drop my dose to 75mg and introduce T3 20mg. Would appreciate any feedback if anyone felt better etc ? Thanks

    I've been on 125mg Levothyroxine for a few years, having lived with hypothyroidsim for over 25 years.

    My blood results before Christmas indicated Hashimoto's so I started taking T3 in December without dropping the Levo dose.

    I started with 25mg gradually increasing to 75mg after 4 months (approx).

    The difference in me has been marked. I feel for the first time in a long time, that my brain and body are functioning. Its not 100% and never will be, but after 6 months I feel like my old self most days!

      Hi Mrs Tweedy

      That gives me hope. I am waiting on specialist (private) writing to my gp (nhs) to write the prescription I am currently on 175mg t4 n wants to start on 20mg T3 reducing t4 to 75mg maybe increasing levo up accordingly after blood tests I was thinking this may set me back but am eager to start to find out. Thanks alot for the info where are you in the Uk? Jo x

      I'm in Scotland but found that the standard NHS blood tests are not as extensive as they should be. The TSH results are the be-all-and-end-all. They told me that my results were fine and within frankly I did know better as I wasn't fine. I sent blood for private tests which confirmed that I was not making T3 hence Hashimoto.

      My darling GP sent my NHS blood results to the area endo, binned the copy of private results and lo and behold, the endo sends a snotty letter saying my results are in range and I'm not ill. Go figure.

      After much internet reseach I found a supply of synthetic T3 and starting taking it following the principles I'd read.

      I shall soon get more private tests done because I've been on the 75mg of T3 for sufficient time to give me an accurate picture.

      I do feel a huge amount better.

      I really hope you see an improvement, but it takes time and maybe you won't notice a difference at first but those around you will do. My husband just noticed that I was so much more positive and willing to tackle things. I hadn't really noticed to begin with but I can see it now.

    Hello Joanne:

    My name is Shelly and I am a nurse in the USA.  I have Hashimoto's disease since 1987.

    I am on Liothyronine T3 only but only 5mcg.  It has helped me come alive. 

    I can't take T4 at all.  I had lot's of problems on Levo and then went to Thyrolar  (liotrix) then  onto NDT Armour Thyroid but T4 does not convert in me and since 2009 I have been on T3 only and feel much better.

    I hope this helps,
