I just took a look at the site you mentioned (http://www.invive.com/).
What a total load of BS! I really hope that the FDA and FTC come down on these guys real hard. Take a look at the scientific information section, where they claim that Silver Ions are toxic, and that their product uses only Silver Atoms which are not!
What the hell do they think an ION is????? You would think that one of their "Lab Technicians with his array of equipment and test facilities" would have a reasonable grasp of Junior High School Chemistry or Physics,but apparently not. They repeat this ridiculously stupid statement over and over again. This is Mild Silver Protein, which at the concentration levels they are pushing is TOXIC. Pure Snake oil.
