I believe this to be true, but I was asked for clarification as to what is it about this process which does that vs sellers who are making the bad stuff which is too small etc?
It's not like that, the main issue with those sellers is that they sell various kinds of ionic silver. This is not colloidal silver and never will be. It also tends to be far too high in ppm with an exaggerated risk of Argyria.
It is a "natural" effect of the process which causes this, and I am frankly not qualified to offer a reason as to why the prosess results in this exact size of particle.
However, it is not ionic silver, which is what these sellers offer; I have never known, or seen an advert for, a seller of true colloidal silver with a USA based website. There are two sellers in the UK who do offer mixtures of Ionic Silver Oxide and Colloidal Silver, but not even these are purveyors of what we would refer to as "the real thing".
