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.
