@LucH Thank you very much
I will summarize in case I have missed something. I am absolutely new here. I haven't got much time to get all the knowledge i wanted to. I thought I have time to learn and then try to repair my thyroid and bile. But with this diagnose I am terrified and I should quickly prepare a plan as the chemo starts in 7 days.
(one more question - I received an advice from friend to start taking thyroid hormone T3 and T4. Should I or the selenium and iodine are ok?)
The plan:

1. Star taking mariendistel desmodium, sillymarin and artischoke - every day (except the chemo day - after chemo with shake)
2. buy some kind of selenium and take it like that - 100 mcg 2x /day at the very beginning and 2-3 days after chemo. 100 mcg the other days
3. Iodine - sorry but I couldn't get what kind should I take - kelp or just iodine, or both
   I start with 150 mcg caps (1 per day) 3/4 days minimum, then a few days with 300mcg and after that?
   and stop it 48 hours before chemo
4. daily take betaine HCL+ pepsin

@LucH I have this one - betaine HCL+ pepsin
Will buy Kelp 150 mcg caps Now foods and Lugol (if confirmed)

@LucH tanks a lot for the immediate answer. Is it ok to take iodine in case one is in hypofunction of the thyroid (or at least I think I am with all the symptoms)?
I think will buy this for the liver (according with your phytotherapy advise) -
Do you think it's ok?

And maybe this one to start before chemo? -

@LucH Do you know if it is ok to take TUDCA during chemo? I have to start chemo (breast cancer) in a week and I wonder what could I take to help the liver and minimize the harm
