Covalent appears to be referring to the binding of the atoms in a colloidal particle. It appears no different than you get with high quality EIS. I cannot find any mention of the ionic content or manufacturing method, so it could be anything from pretty well normal EIS like we make, to sputtered silver like Frank makes.

Could someone explain the difference between Covalent Silver and Collodial Silver? I am traveling to England, Scotland and Wales next week - and with the e-coli everywhere I was told to spray the foods with Covalent Silver but not knowing the difference I am asking the more knoweleable among us. I have CS and planned to take it along, as well as, del-immune but would like to cover all my bases. Thanks for the help.
