Hi Greenfingers, are those ranges in the UK? If so, they must be different for people taking hormone since some people here are way over 2.0. The real question is what your FT4 and FT3 look like. How do you feel? Do you have symptoms of any kind?
What they are saying is that if your results are 0.2-2.0 you might be optimally dosed.
For most people 100 to 300 mcgs. may be the optimal dose but yours needs to be specific so if you feel good at 100 (I don't think most people do), you can stay with that. If not, you will be permitted to raise another 25 mcgs. until you feel well.
Other factors should be tested and you can compare them here. Those all have a bearing on how well you feel, too. stopthethyroidmadness.com/l...
