Hi guys, I have hashimotos and currently take 100mg Levo from my GP and 20 Lio which I buy myself as I had zero improvement on T4 alone, had to finish work etc,etc. I am much much better with T3, I can stay awake much much longer, my hair grows, I am no longer always cold. My old Gp was so incompetant that I hadn't had a test for around 4 years, but as I used medichecks I didnt care.
Having moved house, my new GP wants to do a test. Can someone please remind me of the famous article about T3 and suppressed TSh please so I can take it to them.
Many Thanks

Are you referring to Dr Toft's article in Pulse magazine? If so then that refers to patients taking Levo only:
“The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range – 0.2-0.5mU/l.
In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l. Most patients will feel well in that circumstance.
But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.
This ‘exogenous subclinical hyperthyroidism ’ is not dangerous as long as serum T3 is unequivocally normal.”
