The way TSH is currently used by endocrinologists and doctors treating thyroid patients is wrong.
The way people are treated, as if they are all the same is wrong, and simply being ‘in range’ on levothyroxine monotherapy is not going to guarantee a good outcome.
I include two research papers in this blog post.
This piece of research is undoubtedly one of the most important studies done in the last ten years.
It finally begins to be more clear that TSH is one of the least useful tools in assessing thyroid hormone levels and whether someone is actually getting enough T3 in the cells:

Hoermann, Midgley, Larisch, Dietrich.
Front Endocrinol 2015 Nov 20;6:177. doi: 10.3389/fendo.2015.00177.
This second research paper concludes that getting TSH into the reference range is no guarantee of good health. It shows how simplistically and poorly TSH is being used today. TSH is not something that should be relied upon in the way it is being done at the present time:
