If you dont know if you have Hoshimoto, you need to find out. Supplements may support but not cure hoshis, you need thyroid
replacement hormone meds for life. Although people on the 'natural herb' bandwagon jump all over natural dessicated thyroid (pig thyroid), in the end its a manufactured medicine. Works great for many (myself included), but its medicine.
If you just have hypo symptoms due to a 'slow' thyoid, the causes can be many, and sometimes it does not last forever.
