I've heard that and that was how I tested. Still, I do believe I have a heavy load. I must've had mine out 8 years ago without much chelation. With hot flashes and the heat here, I have no problem sweating, though, so maybe I'm clearing some naturally?? I hope so. I know I need to get more proactive. I kept forgetting to take my Clear and Algin yesterday while working... So missed a day already. Today i think the parasites are hungry, too, (hungry!) but i've been good even though my husband bought me a peppermint patty which is sitting in there in the fridge : ) I asked him not to do that if even for blood sugar issues. Just knowing I even have some in me is good enough cause none should be....either way - if its in there its not good. I'd definitely protect yourself if you use it, though, cause you are dumping some in your blood!!!
