Hello everyone. I have been diagnosed with under active thyroid 6 years ago. I was on 50mcg Levo for years, during Pregnancy it was upped to 75mcg. To be honest I have never felt any difference after taking it. I have recently put on 2 stones, I have no energy, I am feeling low and have other symptoms of underactive thyroid. I am going to my GP next week but I know they will be reluctant to even test my T3, free T4 and thyroid antibodies. They normally test TSH and it is always 'normal'. I will try to get my minerals and vitamins deficiency tested but have no hope. I am considering buying T3 from the health store but I doubt it is a genuine liothyronin. I would like to order some pills from abroad but don't know how much to take and where to order them from. Please advice.
