The other study, which I have also seen, was conducted solely to prove that uncontaminated small particle silver does not accumulate in the body and cause Argyria. It did nothing to prove ionic silver was as good as or better than Colloidal Silver .

Here's the link. The second link was the link you were looking at. Colloidal Silver particles made with electrolysis are on the nano scale more than small enough. Ionic silver regenerates tissue creates stem cells and is more effective at killing pathogens than a colloid. And now you claim Utopia-Silver was 35% or something Ionic all along and they now have an Ionic Silver product.
