How important is particle size and is a high ppm colloidal silver product required for effectiveness?
You cannot judge colloidal silver products based solely upon parts per million (ppm), but a smaller particle size product is potentially more effective. Silver is only effective to the degree that the surface area of the silver particles are able to come into contact with a micro-organism. I’ll exaggerate with size so you can get a clear mental image of this concept. Imagine a silver particle the size of a 55 gal. barrel with the outside of the barrel being the surface area that comes in contact with the surrounding environment; then compare that with the same barrel filled with silver particles the size of marbles or BBs. There are many times more effective surface areas to contact the surrounding environment with the smaller particles than with the larger particles. It also enables them to travel more easily in the body’s fluid environment. High ppm products generally are comprised of much larger particles suspended in a gelatinous base to keep them from falling out, which means that
