I have had Thyroid issues for nigh on 20 years and probably undiagnosed for a lot longer until I came across a famous BioHacking person who advocated the merits of the supplementTMG . In summary it deals with inflammation issues in the Liver.
I trialled TMG 6 months ago and it literally changed my life within 48 hours.
I refused Thyroid meds after suffering horrid side effects and have not taken any conventional prescribed meds for 14 years. Obviously there are some risks to making that choice but I can honestly say taking TMG has been a life changing for me and taking me down a path of researching more about functional medicine.
Each to their own but I feel this is the way forward when trying to resolve unremitting health issues.
