Hi Trader ,
This information is not false, this is what my Professor Endo told me when my FT3 was borderline low and I asked him to add some source of T3.
He did agreed and after two months it turned out I did not need the T3 and that all what I read on the web regarding FT3 should be in the upper third is the false information, and my TSH was sufficient to treat my hypo.
Best wishes ,
Your "professor" should be brought up on charges for malpractice. A healthy adult with a normal functioning thyroid will have free t3 levels i the 3/4 range. Thats easily backed up by scientific data. Does he not want his patients to be normal? Or does he want to cater to big pharmaceutticals who line his pockets? Does this professor throw oit the scientific fact that the number one cause of hypothyroidism is autoimmune disorder. Autoimmunity that causes inflammation. Inflammation not only reduces the bodies ability to convert t4 to t3, it reduces the cells ability to absorb t3(the number one energy producing substance every cell in your bodh requires) and raises cortisol.
Your "professor" should also understand the role of TSH in the HPA Axis. By treating by TSH alone a d disregarding thyroid hormones(remember TSH is NOT a thyroid hormone) he is throwing off the natural balance of hormones and steroids produce by the hypothalmus, pituitary, parathyroid and adrenals, among others affectly by those hormones and steroids the body should be producing, which tthey either will over or under compensate for now that youre supplementing only ONE of the thyroids hormones, namely t4.
Besides converting t4 to t3, the thyroid also produces its own t3, along with t2 t1 and calcitonin. By introducing synthetic t4, which is not a biologicly identical hormone to human t4(and the reason levothyroxine and its variants have been recalled over 100 times by the FDA) you futher stunt the thyroids ability to produce the other hormones it naturally would produce.
I can go on and on why your "professor" should be thrown out of the medical profession, unfortunately thats not going to happen because the medical community is all about
big money and NOT a patients health.
If you want to give people advice based on scientific research, use proper research. Not studies backed by big pharma, and most definitely not by your "professor" endo who treats a patients thyroid condition based off a pituitary hormone!
