As it turns out, there is a trace mineral called selenium that plays an important role in thyroid biochemistry. Selenium deficiency has been implicated in the etiology of Hashimoto’s thyroiditis, and just by supplementing with selenium, there will usually be a decrease in antibody levels.

This was shown in an elegant study from Crete published in 2007. This study reported a 21 % reduction in TPO antibodies after one year of selenomethionine supplements(200 mcg per day). I thought this was rather impressive.
