Hello. This is my first time at this site. I wanted to share with you what we have been told by our child's doctor after he tested high for Thallium, Tungsten, and Antimony on a fecal metals post challenge test. He told us that virtually all beds and bedding are treated with fire/flame retardants which can cause toxicity in some people. You can obtain bed and bedding products free of these chemicals, but you may need to get a doctors note before you can purchase these products. You can, as you probably already know or are doing, try chelation to remove levels that are already problematic. Please share this this bit of info. with all those interested. Take care, and God Bless our children...
