Hello
Thyroid gland produces 2 hormones ,,,T3 liothyronine and T4
thyroxine , T4 is converted to T3 for any active action
T3 is marketed as liothyronine like tetraoxin or diotroxin (combined with T4)
T4 is marketed as thyroxine , eltroxine , part of diotroxin
All post radionucleotide ablated cancer patients or primary hypothyroid take T4 as international guide lines
T3 alone or combined with T4 is taken in
thyroid cancer patient who have to undergo thyroid cancer scan like for 2-3 months , or who had to undergo
chemotherapy for thyroid cancer spread, according to international guide lines
But in trials underway , are telling us that T3 + T4 combinations are effective in improving , mood , confidence , general well being , than T4 treatement alone
So if low mood is there , try diotroxin , for a month or so , but do get thyroid levels after that month , as combinations increase the
TSH, you can also add T4 + ( T4+T3) as dose is 1.6 x body weight
Hope this helps
