Nanoparticles in high quality colloidal silver are treated with a coating that does not break down in the stomach. This is potentially superior to solutions that can be produced at home.

Further, it takes copious amounts low-quality silver solutions to build up enough to turn a person blue. This is why it is an extremely rare side effect. And again, this is still the ONLY side effect that has ever been associated with colloidal silver.

Western medicine, on the other hand, kills more than 700,000 people a year--that's a pretty nasty side effect to "healthcare". Colloidal silver is an alternative to the options presented there.
