Some colloidal silver products of higher concentration (ppm) claim that one teaspoon equals multiple teaspoons of our 10 ppm product. On the contrary, scientific peer-reviewed literature has shown that silver is only useful when it is positively charged (bio-active). Bio-Active Silver Hydrosol, with greater than 98% bio-activity, is 8x more potent than a 250 ppm colloidal silver. Higher ppm also= risk of toxicity. There is simply no reason to use a higher ppm product. Launched in 1999, Sovereign Silver Bio-Active Silver Hydrosol is the ultimate refinement of colloidal silver and has proudly been the #1 selling colloidal silver in the United States since 2005. Benefits: Only two ingredients: 99.999% pure silver and pharmaceutical-grade purified water No added salts or proteins that render other silver products less effective. Packaged in non-leaching glass bottles, never plastic.
