actually, i'd still like an answer to my question-- how would i know the chelators are doing their job? everybody is different. just because something is a chelator, does not mean it would work for everybody and i'd rather not waste time and money on a supplement i don't know is working or not. so how can i tell or test if i'm not having a reaction? i mean im aware some reactions might be pretty minuscule and i could easily miss it..
