Yeah, I had never heard of it. But its funny. Here we ar ein t US where everyone thinks we have the "best" medical care in the world. Hhhhm, I wonder. Seems like we are way far behind with the simple stuff. If you can't make money on it, it is not done here. IN any event , my research so far indicates that copper overload is the biggest reason for mercury overload, it is a catalyst. In other words, it is the copper toxicity that brings so much mercury into the body. Then again , I don't have much mercury in my system. But I was never tested for copper that I am awayre of. I think I am going to do a hair analysis is and find out.
