BIO-ACTIVE SILVER - "Colloidal Silver" has been used since the late 1800s in countless applications, and encompasses a wide variety of silver products. Many contain (claimed or unclaimed) salts, proteins, compounds or stabilizers - all of which affect the safety and efficacy of silver. 98 PERCENT CHARGED - Sovereign Silver has only two ingredients: 99.999 percent pure silver and pharmaceutical-grade purified water. It does not contain added salts or proteins that render other silver products less effective. OPTIMAL ABSORPTION - The smaller the particle size, the easier it is for the body to absorb and eliminate. Sovereign Silver features an unprecedented particle size of 0.8 nm/0.0008 microns, verified by 3rd party. No other silver can prove the same. SAFETY - When it comes to concentration, more is not always better. Our tiny particle size yields greater surface area and higher efficiency, making our 10 ppm (parts per million) product more effective than competing brands containing up to 500 ppm. PURITY - packaged in non-leaching glass bottles, never plastic, to guarantee purity throughout its shelf-life. Sovereign Silver is vegan. It is also allergen-, glutten- and GMO-free.
