Innovative Natural Products silver is true colloidal silver. It is not Ionic silver like many competitors offer and claim they are true colloidal silver. Ionic silver is mostly clear and produced by electrolysis. It will generally have only a PPM around 5 to 30. However, true Colloidal Silver stays in suspension indefinitely and contains much higher PPM values. The process is scientific, complicated and precise. It requires scientific techniques and laboratory procedures and equipment to be made properly. Innovative Natural Products’s Colloidal Silver is non-reactive and will not degrade or fall out of suspension which provides an extended shelf life beyond mandated nutritional expiration requirements.
