To answer your question is this not Colloidal Silver ? No it is not. The 5 bottles you mentioned are MINERALS. They are colloidal minerals I am sure but will not do anything exept give him minerals in a better form than pills. Colloidal Silver is an entirely different thing. You can get it at a health food store but is quite expensive. People who take a lot of it for various reasons, usually make their own, as I do. A tsp. a day for the silver is not enough for someone who is very ill. It would do for maintenence for a healthy person. He needs to take at least an ounce[I would use a 1/2 cup at a time] and take some every hr.or 2. I use the silvergen silver maker. It is easy and shuts off at proper time for strength of silver. I hope this helps..
