“You can look this up for yourselves, but when I did I found out there are two different things sold as "colloidal silver" and this is actually ionic silver. Ionic silver stays in the body (so can build up over time) whereas real colloidal silver is treated as a nutrient by the body and passes through the system. Colloidal silver is made in a lab and is the more expensive product. You can make ionic silver yourself cheaply at home. So if this difference interests you please look it up. This product has been mis-labelled by the manufacturer. Fortunately the retailer I bought it from, Evergreen, accepted the return and refunded my money.”
