Experience simplicity at its finest—Sovereign Silver’s Bio-Active Silver Hydrosol contains just two ingredients: ultra-pure silver and pharmaceutical-grade water.

Sovereign Silver’s story began in 1966, when founder Stephen L. Quinto sought a cleaner way to care for his swimming pool. His curiosity led to the discovery of silver and copper ion generators, and later, a passion for refining colloidal silver. After years of research, he launched Natural Immunogenics Corp. in 1998, introducing Bio-Active Silver Hydrosol and the Sovereign Silver brand. Today, the company remains family-owned, led by Stephen’s sons, and continues to innovate with a focus on quality and purity.
