Argentyn 23, 473ml bottle

Greater than 98% bio-active silver ions and nanoclusters. Exponentially more powerful than other brands, even those with 250, 500 and 1000 ppm. 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. Unprecedented particle size as small as 0.8 nm (nanometers), validated by Transmission Electron Microscopy, allows for easy absorption into and excretion from the body. Argentyn 23® Bio-Active Silver Hydrosol™ has only two ingredients: 99.999% pure silver and water that meets USP-NF standards for pharmaceutical-grade purified water.
