So? My sister has taken that for 50 years and is healthy as a horse. You are grasping at straws here.
Taken what? Please be exact. Natural or synthetic?
I was diagnosed as hyperthyroid back in 1978. Thin as a rail, shakes after minor exertion, sweating. It was diagnosed before the bug eyed effect took place.
Thyroid killed with radioactive iodine, and I have been on Synthroid since. No problems.
