What's interesting with the Ionic vs Elemental debate is where both types will possess ionic properties to some extent or another.
That said, what's equally interesting is that which is commonly referred to as ionic silver, is not truly made up of silver ions, as these are so unstable(reactive), that their existence consists of mere microseconds passed the point of disassociation(from the anode).
Therefore what we typically end up with from an LVDC process, is predominantly silver oxides. Which in effect, is a semi-aqueous silver compound that will phase in-and-out of an ionic state from solubility. And in turn, resulting in what we'd call, unstable solutions. - ie, reacting to light, air and /or loosing vitality etc.
However, I'd also add that this in itself does not mean that these solutions are any less effective than particulate counterparts. In fact, it's quite the opposite, as Colloidal Silver works ionic exchange. That is to say, the interexchange of ions in the presence of reactive organisms(or media). To which I'd add, the predominant ionic solutions will hold the upper hand over a neutral particle in most cases.
The downside of course, is that these ionic
solutions are prone to destabilization and is where the old saying "fresher is better" comes into play. Therefore, the idea here is to try and strike a balance between the ionic and particulate(elemental) components, so that the solution can be as effective as possible for a given task. - which will likely vary according to the application.
And so in conclusion, I'd answer that the answer in this case, is that it will vary. ie, if I was aiming for the gut, then I would process for maximum stability and resistance. However, if I was treating a systemic condition such as an infection, then I would push as far as possible to ionic side, for maximum diffusion(sublingual) potential and effectiveness.
- hope this helps
PS. heating ones solution while processing is a two-fold in that it reduces the silver oxide to elemental silver(at the cathode) while also increasing solubility. - this in turn, has proven to produce one of the most effective Colloidal Silver solutions I've ever used.
