i disagree. chelating does not make things worse. as with any other cleanse or diet, when your body rids itself of toxins, side effects will occur, it doesn't mean chelating causes brain damage. i'm sure our bodies have natural ways of ridding metal, but that could take years. herbs and supplements are recommended because they speed up that process. i think rather than disbelieving chelating therapy, you should focus more on your diet and exercise while chelating, because that will help your body rid metal more efficiently and prevent re-exposure.
