My brother sent me (snail mail) this guys newsletter because he knows I take CS.
He showed a picture of the Blue guy, and basically mirrored the main media about CS. Among other things he stated:
“there are hundreds of references on silver in medical literature, but not one of them points to a clinical study proving the efficacy, or safety of colloidal silver taken by mouth.”
“The buildup of silver in your system can lead to neurological problems, kidney, ingestion, headaches, skin irritation, and who knows what else”
