The best quality Colloidal Silver is produced by the True Electro-Colloidal Process, not the chemical or grind methods. Ultra fine particles of silver are suspended by an electrical charge in distilled water. The force of the electrical charge is stronger than the force of gravity, so the silver particles remain suspended. When Colloidal Silver is improperly manufactured, the silver particles can be too large and/or have no electrical charge, causing them to fall out of suspension and reducing the value of the solution. Colloidal Silver by Innovative Natural Products® is produced by a True Electro-Colloidal Process. It contains silver particles so small that they measure only .004 - .017 microns in size. The tiny size of the particles combined with the proper electrical charge makes Innovative Natural Products® Colloidal Silver the best product on the market today. We do extensive laboratory research that includes measuring ppm (parts per million), effectiveness and safety. The color of Colloidal Silver is also important. The darker the solution, the more potent the concentration of silver, as proven in laboratory testing. From our research we have determined that many companies simply do not know how to manufacture Colloidal Silver properly. As a result, they are only able to produce Colloidal Silver at low concentrations. Innovative Natural Products® Colloidal Silver does not lose its charge and stays suspended in the solution at any concentration. Glass is the preferred choice for storing Colloidal Silver for any length of time. Plastic containers cause the electrical charge to be drawn out of the solution, thereby rendering the solution less effective. Glass holds the electrical charge and enables the product to remain in suspension.
