What is Sovereign Silver?

Sovereign Silver is the premium silver supplement in North America for immune support*, trusted by millions for over eighteen years for its unprecedented safety*, quality and efficacy*. Bio-Active Silver Hydrosol represents the ultimate refinement of the colloidal silver category. It contains more than 98% bio-active silver ions and silver nanoclusters, in pharmaceutical-grade purified water.

Their colloidal silver technology is the best and most advanced in the industry. Sovereign Silver features an unprecedented particle size as small as 0.8 nm (nanometers). No other colloidal silver can prove the same. The smaller the silver particles, the greater the surface area and the easier for your body to absorb and excrete – making our 10 ppm concentration more effective* and safe* than competing brands.

Pure Family

Natural Immunogenics Corporation founder Stephen Quinto became familiar with silver’s antimicrobial properties in 1967 when searching for non-chemical methods to keep his swimming pool water clean; he selected a process using both silver and copper.

Stephen began researching colloidal silver for immune support in 1997, working to isolate silver into miniscule particles that could achieve near-perfect dispersion. Natural Immunogenics was founded in 1998 to continue and expand his research and product development, and the first bottles of Sovereign Silver Bio-Active Silver Hydrosol™ shipped to retailers in 1999. Two years later, Argentyn 23®, a derivative professional line based on the same technology, followed.

Always intended to be a multi-generational company, in 2009, Stephen passed the torch of leading Natural Immunogenics to his sons, Theo & Benjamin, who had joined the company 9 and 1 years prior, respectively. The brothers continue to this day to safeguard their father’s legacy by ensuring that the culture of the organization – family, passion and pride – remains unchanged as the organization grows. All in an effort to help people achieve their own health sovereignty.

Why Silver?

Silver has been used for more than 2,000 years to help safeguard human health. It is a natural element that can be found in whole grains, edible and medicinal mushrooms, mammalian milk, spring water, sea water and tap water.

From the time of Hippocrates, silver’s health protective properties were well respected. Silver was used to help protect the purity and safety of drinking water throughout ancient Mediterranean civilizations.

Known to be an effective antimicrobial, silver was used extensively to heal wounds and treat infections from ancient times through the First World War. Silver nitrate is still used in the eyes of newborn infants to prevent infection, and NASA relies on silver ions to help purify water on the International Space Station. (read more about the history of silver here)

As people search out natural ways to support their health and well-being, silver is gaining more widespread recognition for immune support.*

Sovereign Silver’s Bio-Active Silver HydrosolTM is the #1 selling colloidal silver in the United States, and it is gaining popularity in Canada and Europe. We also produce Argentyn 23, available through healthcare professionals, and Sovereign Silver First Aid Gel (topical medicine).
