"These are some of the non-thyroidal effects of selenium deficiency. The effects of selenium deficiency on thyroidal health is even more interesting. One study I read indicated that in experimental animals, selenium deficiency will increase T3 in the heart. This may be the reason that selenium deficiency causes heart palpitations and rapid heart beat, which is common in thyroid disease."

I didn't know selenium deficiency could cause it.
