At least the ionic crowd is not nearly as militant here for the most part as they are in some places on the net. Ah, the stories I could tell and encounters I have had!
Perhaps worth noting is that practically all ionic silver does contain some Colloidal Silver - generally up to 15%. By the same token, most "true Colloidal Silver " solutions actually contain some ionic content - and that too is generally up to 15%. Thus, no matter how inferior ionic silver might be for internal applications (it is fine for most topical applications), it would still be effective internally due to the colloidal content, though that effectiveness would be further reduced significantly by the larger particle sizes.
I am at a bit of a loos when it comes to "reduced Colloidal Silver ". Perhaps you could point me towards enlightenment on how one "reduces" ionic silver to bring about a kind of colloidal silver.
