Yes Fred, that's true. But the PROCESS of these toxins moving out from the cells in your body, through your bloodstream and into urine and feces can be VERY HELLISH for some of us... with some pretty nasty symptoms along the way. I am ALL FOR getting the VERY TOXIC metals out, but I'm preferring to do it S-L-O-W and easy, so that I don't end up with cardiac arrhythmia for five days in a row... like I had the last time I took the B12. I can handle headaches, fatigue and nausea, but not the atrial fibrilation. It's WAY BEYOND my comfort zone. I should tell you that I had the same kind of heavy metal detox reaction whenever I've taken Lauricidin, which is a natural anti-viral that also acts as (what they say) is a "MILD" chelator. The metals really OVER-stimulate my nervous system, cause enormous pressure/discomfort in my frontal brain and then set my heart into atrial fibrilation. I would love to know what could possibly EFFECTIVELY NEUTRALIZE the heavy metals once they are in circulation (and reeking total havoc) upon the body systems? I've found that high doses of N-A-C are the ONLY thing that really helps relieve my symptoms at those moments. Also chlorophyl and fruit pectin kinda sorta help. If you have any ideas let me know.
