Ionic silver is not bad for you unless it is improperly made. From everything I have researched and observed, true Colloidal Silver is much superior internally. I trust the information at Purest Colloids. I also trust my friend Steve Barwick, at least to a fair degree - but we should always keep in mind that it is to Steve's advantage to write and link to things which say that ionic silver is superior.
Also, there actually are home generators which make real Colloidal Silver . A bit pricier, but they are out there. The silver they produce is not up to the quality of Mesosilver or Advanced Colloidal Silver , but it IS true colloidal silver. Takes many thousands of dollars, even tens and hundreds of thousands of dollars for equipment that could produce silver that could compete with Mesosilver or Advanced Colloidal Silver and their superior quality high voltage reversing polarity generators and submerged plasma beam production methods.
