Thanks Olif. That's really encouraging. It's amazing that you felt a difference so quickly and with your amalgams in. I'm going to look up information on the other clay products too. The testimonials for natural cellular defense look encouraging as well - but I've tried so many things that help others and do not help me - so I don't get my hopes up too high. But this definitely looks like it's worth trying. My chiropractor said that he heard good things about it with Autistic kids - and also said that he felt it would be a good way for me to start - he feels it is much safer than the other chelating agents and effective too. My dentist said that he did a DMPS challenge before and after using it for a period of time on himself - and it definitely lowered his mercury burden. Thanks again.
