A Silver Hydrosol is a colloid of ultra-pure silver suspended in ultra-pure water. Even though other brands claim only water and silver in their formulations, this is hardly ever the case; one can find proteins, compounds, stabilizers, contaminants, oxidation and other ingredients, in them, which should never be present. Features: Smallest average particle size ever seen and documented (0.0008 microns or 0.8 nm) - more surface area than any competitor Most amounts of "active" particles (96%) - confirmed by the University of Miami - particles are propelled towards their target. Ultra-pure water, only other ingredient Safe, low concentration of 10 ppm, safe for the whole family, even infants. Ph 6.7 Crystal clear and virtually tasteless. 3 rd Party studies prove Sovereign Silver to outperform all competing brands up to 500 ppm. Dosage: Recommended ingestion for adults - One teaspoon daily or every other day taken on an empty stomach. We recommend 1/2 dosages for younger children, or as directed by a licensed holistic health care provider.*
