Ultra Silver Dietary supplements sku-5066158232 500 PPM

Ultra Silver dietary supplements are Unisex colloidal silver, sold as a 3 Pack of 4 Oz amber glass bottles (size 4 oz). This 500 PPM product contains nano-sized silver that the maker says stays suspended indefinitely without settling or degrading. Production requires laboratory-grade techniques and industrial equipment. The silver is nonreactive and shelf stable, including in storage.

Ultra Silver says it independently tests and guarantees its parts-per-million concentration and shares the results in the product pictures. A TDS meter measures total dissolved solids, not PPM. The maker distinguishes colloidal silver from clear ionic silver products, which it says have a PPM below 30 and can be made by electrolysis.

It describes the color of concentrated colloidal silver as changing from golden amber to dark brown. Ultra Silver says its product is typically 15 to 50 times more concentrated than competing products. The bottles are glass even though the maker describes the product as nonreactive.
