Scott,
For heavy metals I use low dose DMSA, as well as natural remedies such as BioChelate from New Beginnings and NDF-Plus from Bioray. The DMSA has worked quite well for heavy metals in many kids. Also, glutathione such as Liposomal Glutathione and transdermal glutathione to support antioxidants and detoxification as well.
I use to use a lot of DMPS (oral and intravenous), as well as higher dose DMSA, but don’t really see the need anymore. Also, many of my patients come to me from a distance so doing IV’s isn’t practical.
Environmental toxicity the NDF-plus works for too, as well as overall methylation and glutathione support. When parents are able to do it infra-red sauna can be very helpful.
