Silver particle size ranges between 20nM and 40nM. The ultra small particle size is most effective against bacteria and viruses because of the ability to pass through cell walls and invade the bacteria and viruses directly. Silver Lining does not require metabolizing by the Liver eliminating side effects that are commonly caused by drugs and supplements that do. Silver Lining contains no additives and does not contribute to the condition known as Argyria.
