Our groundbreaking nano silver liquid offers a distinct advantage over both colloidal and ionic silver products. Nano particles deliver the silver at the smallest possible size, meaning you get an incredibly powerful, non-toxic form of silver with zero build-up in the body. Many of our customers consider this their most essential supplement. The small size of the silver particles is important because smaller particles provide a greater surface area per volume which in turn allows the silver to exert a greater effect. The particles are typically 0.01 to 0.001 of a micron in diameter (about four hundred thousandths to four millionths of an inch), with a positive electrical charge place on each silver particle. Packed in the medical grade violet glass to best preserve the integrity of liquid.
