Natural Immunogenic Corp. is a family owned business that leads the industry in colloidal technology research and product development. Founded in 1998, we produce Bio-Active Silver Hydrosol™ and Silver First Aid Gel for consumers under the Sovereign Silver brand, and for professional practitioners under the Argentyn 23®  brand.

Stephen Quinto, who founded the business, upon his retirement passed the leadership on to his sons, who remain passionate about and committed to our mission. The advanced analytic equipment we have in our laboratories enables us to further our research and ensures that we can consistently produce pure and effective Bio-Active Silver Hydrosol products.
