Your question created a firestorm between our Guru Expert Steve Barwick and the marketing at Mesosilver! My BS meter went WILD and exploded in a fireball.
The Mesosilver Marketing is diametrically opposite to Steve Barwicks research. Conflicting statements are the way it is in the world Colloidal Silver ! If it weren't for Steve Barwick, we would all be in a loony bin.
Meso marketing says in effect that Particle Silver is superior to ionic silver, and that ionic silver is destroyed by stomach acid.
Clearly one of them is DEAD WRONG. I researched this tough question most of the day today, and I have confirmed that our Guru Steve Barwick is once again the clear winner.
In this tough case, the issue is called metalloproteins which is in our saliva, stomach & intestines - and binds to ionic silver (not particle silver) and carries the silver ion throughout our body into our cells. This is why we should hold CS under our tongue for a few minutes, so that more CS Ions bind with the metalloproteins, and some even gets directly into our bloodstream. Then when we swallow the CS, metalloproteins in the stomach & intestine carry the ionic silver through the stomach acid and into our bloodstream, and then into our cells.

So our goal is to take Ionic Silver made at low current which creates nano sized particles. Depending on the size of the silver wires, 5 milliamps or so is recommended from a 27 volts or more supply.
So bottom line? Which is the best Colloidal Silver to buy? I don't know yet. It is mission impossible to wade through the mumbo jumbo of marketing bullcrap fog. We want a product that is mostly ionic with nano sized particles and 20ppm. Very simple. ALL of our home generators produce the desired ionic silver.
