My son is chelating now for the first time. He is 16. He never tested high in metals before but most recently tested high for lead and arsenic.
You should first have your son tested for metals using a "trial" dosage of DMSA. If the tests come back that he has high levels, then he will benefit from this treatment. A DAN doctor can help you with this. If someone wants to chelate without first testing to see if he needs it, I would be concerned.
I highly believe in it. I have seen major changes in kids. My partner does chelation therapy on kids. It starts flushing out the metals. have you ever heard of biofeedback? Again, I have seen remarkable progress. I would be happy to share my experience with you.
