We did use Chelation Therapy for my son. We did it under the doctor's guidance, of course. The reason why we chose to do that is because his labs came back really high with the toxic metals in his system. As a mom, I just didn't feel good knowing that he was high in these metals. Under the doctor's guidance, we used different forms of chelation. When we were able to find one that was successful and get his levels back down to an acceptable amount, we were able to see some great progression in him as well. He had more speech. He had more focus of different aspects of his day, which was great to see.
