when I had 3 amalgam fillings removed 3 months ago I did not take any thing and for about two weeks I was in bad shape ,then Igot a news letter from dams that mentioned taking activated charcoal 4 capsules right before amagam removal and 4 more after , then 4 capsules daily for two weeks this will absorb any swallowed amalgam that sliped past . I followed there advise and i only felt bad for 2 days after having the rest of my 6 amalgams removed you can find it at most health food stores or vitamin stores ,good luck
