I do suspect I have mercury. I don't have amalgams anymore, but I did 20 years ago, had them removed the wrong way by a regular dentists (at the request of my mom who didn't know about the correct procedure at the time). I was not even in good health before that, and a lot worse after that.
Anyway, maybe I've gotten a lot of it out with iodine supplementation, selemium, etc. Hopefully what v says is true about zinc/mercury. I'd like to try it in small doses.
I haven't done hair analysis, but have thought about it, and may look into doing that soon.
