You want to reduce the IS(Ionic Silver) to CS( Colloidal Silver ) as its not as toxicto the body cells and silver ions gointo the cells and get trapped there causing Argyria. When Cs hits the stomach it passes on through while ions mixed with syomach acid get turn into silver chloride (basic chemistry) Look up the studies with IS vs CS. A little IS is not going to hurt you in the small amounts, but everybodies level that will cause a problem is different! Cs has a much better chance of getting to your other parts of the body with out being locked up because its not an ion. Just do your research on this so you are informed!
