What are the benefits of taking Levo and also T3? My GP took me off my 150/175 Levo 3 weeks ago, and I am now on 40mcg T3 daily. He said he didn't know why people would stay on Levo when transferring to T3. He and I wonder if I have a conversion problem. Though he did say he hadn't used it much, so didn't know a huge amount about it. I definitely feel a lot better, now feel able to actually do things I see that need doing.
But why do people use a mixture of both?
