Also I've tried pretty much all Peaty supplements. Most of them don't help or make things worse.
The only stuff that has helped me is 1. taking thyroid (natural desiccated thyroid) and 2. taking things that help reduce SIBO and modulate gut microbiome (antimicrobials, antibiotics). Improvements from thyroid are gradual and sneaks up on you over weeks and months. Mega dose fat-soluble thiamine helped with energy levels but caused other issues so wouldn't necessarily recommend.
I read that taking kidney extract should help us to recover. Unfortunately I can not get it here in Turkey. I tried adrenal cortex but it does not work. In a facebook group a women said she tried adrenal cortex as well without effect. Until she took full kidney extract.
What helped me is actually turpentine. But the herx effect got too heavy so I stopped last week. Turpentine should get rid of sibo and candida. Wich is also in small intestines. Called sifo. But the recommended dose is 3 days a week. I did 2 weeks without a break lol.
