I would never chelate with amalgams in place. A chelating agent will chelate metals; whether in amalgams or in your blood or tissues. Listen to Olif when he says the benefits were short lived... get those amalgams OUT before you chelate. Maybe a healthier person could tolerate NCD with amalgams in place, but you've already stated you are a sensitive individual. Pam (new to this forum but not new to mercury)
NCD is a passive chelator. It will not pull out mercury it will bind with Hg that is in a fluid. Once the hg is in the zeolite cage it won't drop it because it has the highest affinity for mercury and the cage can't be metabolised. I don't believe in lowering mercury in the body when you still have the amalgams but with zeolite it should be harmless.
