There are 2 statements in my research that apply to your condition.
1) ALL thyroid problems are caused by iodine/selenium deficiency. ( as well as a Pandoras Box of additional health problems)
2) Start your co-supplements first, then a month later start your Iodine SLOWLY and start with a drop of Lugols once per week, then very slowly titrate up to 50mg a day.
This should work. Please do keep me informed for my research. I will include your experience in my doc.
