I have been on T4 and T3 tablets for 10 years but bought NDT on line and felt much better previously.
I sourced cheaper NDT from Thailand at first but was worried about the quality.
I then paid for Canadian NDT but it was very expensive and I reverted to GP prescribed synthetic Thyroxine and triiodothyronine.
Can anyone recommend a reliable, reasonably priced source of NDT that they have tried and tested for themselves?
