Experience simplicity at its finest—Sovereign Silver’s Bio-Active Silver Hydrosol contains just two ingredients: ultra-pure silver and pharmaceutical-grade water.
Created using a proprietary process, this spray features a small silver particle size, verified by independent testing. Its neutral taste makes it effortless to use every day, whenever you need it.
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.
