Company History

Our story begins in France in 1966. That's when founder Stephen L. Quinto was looking for an alternative to chlorine-based systems to keep his swimming pool free of bacteria and algae. Through his research, Quinto was introduced to silver and copper ion generators. These worked well and allowed him to keep the pool clean and at a consistent temperature of 88°F year-round.

In 1997, one of Quinto's colleagues shared with him some new information concerning the phenomenon that is colloidal silver. After a thorough review of the material, Quinto realized that the reason his pool was kept pure all those years ago was because it was utilizing colloidal silver and copper. It also became clear to Quinto that what was being offered in 1997 as colloidal silver was essentially an elementary derivative of the same formulations that were widely used in medicine when he was a child. The technology had not evolved since that time, when such products were in widespread use by medical professionals.

It was in this moment that Quinto began his journey in colloidal silver. Quinto was eventually able to isolate silver into particles so small; they were almost indistinguishable - even on an electron microscope! The silver's near-perfect dispersion represented not only a breakthrough in the science but the ultimate refinement of the colloidal silver category.

Quinto spent the next three years in research and development, sending his findings to various professors and universities who confirmed he had created a colloidal silver that was so fine, it was highly effective even at dilutions of 150ppb (parts per billion).

In 1998, Natural Immunogenics Corp. was founded. In 1999, the company built its own laboratory in Miami. In December 1999, the family owned and operated business introduced Sovereign Silver® to the U.S. marketplace. Two years later, Argentyn 23®, a derivative professional line based on the same technology, followed. To satisfy increased demand for its products, and to further its research and testing, the company built a larger laboratory in 2003.

By 2005, the product line was the #1 selling silver supplement, according to SPINS. The brand continues to be the #1 selling silver brand in North America and is also sold throughout Europe and Canada.

In 2008, Natural Immunogenics introduced the world's first Homeopathic Silver First Aid Gel, the topical form of its popular supplement product. Two years after that, the company expanded its facility and operation further in 2010. However, only three years later, the company was already looking for a new home, and relocated to Sarasota, FL.

Today, Natural Immunogenics is still family owned and leads the industry in the research and development of colloidal hydrosol products. The company operates out of its own custom, state-of-the-art facility and laboratory, where it continues to perfect colloidal technology and is focused on launching copper and gold colloids, as well as a range of topical products. The company continues to research, test and develop new products to serve a growing segment of the population looking for natural ways to maintain their health.
