Bio-Active Silver Hydrosol™ To support your immune system for all of its needs. It has a unique combination of five benefits no other manufacturer can match: Actively Charged (Bio-Active) As corroborated by a university study, Argentyn 23® contains 96% actively charged silver particles (positively charged [Ag+] silver ions), at least 55 times more powerful than other brands. Easily Absorbed Argentyn 23’s® unprecedented particle size of 0.0008 microns, or 0.8 nanometers (validated by Transmission Electron Microscopy), allows for easy utilization by — and excretion from — the cells and body. Less Is More Our ultrasmall particle size also results in a greater silver surface area. That’s why even with a low concentration of 23 ppm (parts per million), Argentyn 23® is still much more effective than brands that contain up to 1000 ppm! Perfectly Safe* Argentyn 23® is formulated to be safe for the whole family. Taken 3 times a day for 70 years, Argentyn 23® still falls below the EPA daily Oral Silver Reference Dose (RfD).† 99.999% Pure Argentyn 23® has only two ingredients: silver and pharmaceutical-grade purified water. It does not contain added salts or proteins that render other silver products ineffective and possibly dangerous. Plus, it is packaged in nonleaching glass bottles.
