I have chelated my son for roughly 2 1/2 years. We first started with DMSA, but he was just so toxic and wasn't nutritionally sound and within 2 rounds had broken an elbow and a toe (I think it was just pulling out too much without him being balanced enough). We then went to a chelation clinic and did saunas as well as EDTA IV chelation for 4 weeks and he was better - well enough to come back home, but wasn't toxic free. We then did bio-tuning along with metal-free, then chlorella and now Natural cellular defense. The bio-tuning has been incredible. We live in California so we were able to do custom CDs, but if you don't live in the San Diego area, you can pick up a generic CD - takes a bit longer, but also works. (www.drjeffreythompson.com). My MD does muscle testing and that's how we determine where to go with the chelators. His mercury - after 2 years is gone, but now we're pulling out the remaining aluminum and arsenic. We still use a home sauna as well.

Best of luck to you,
Debbie
