"The fact that ionic silver changes chemistry once it hits the digestive tract is stated wherever I've seen research on ionic silver (though the vast majority of studies are on colloidal)."
Vairagi is referring to Particulate Silver when he says real silver.
Once again you are confused by the Mumbo Jumbo BS & Hype used by CS marketing reps to drive us all crazy. You are confusing marketing hype with research. The term " Colloidal Silver " includes both ionic silver and particulate silver. There is no such thing as "True Colloidal Silver ," just another marketing hype term used to confuse the consumer.
