Argentyn 23 Bio-Active Silver Hydrosol is the most bioavailable, pharmaceutical-grade silver supplement available — a 23 ppm (parts per million) bioelectrical silver ion solution used by integrative physicians, naturopathic doctors, and healthcare practitioners for immune support, antimicrobial activity, and wound healing applications. 4oz amber glass bottle with fine mist or dropper top (as specified). 4oz.Argentyn 23 is categorically different from conventional colloidal silver supplements: it uses a bio-active silver ion (not silver particle) form — over 98% of the silver is in the ionic/charged form that is immediately bioavailable and active. Silver ions have been documented to disrupt bacterial and viral cell membrane function, inhibit essential respiratory enzymes, and bind to bacterial DNA — providing broad-spectrum antimicrobial activity against hundreds of pathogens. The pharmaceutical-grade manufacturing process produces an exceptionally pure, stable solution with no proteins, casein, gelatin, or saline additives that reduce silver bioavailability in conventional colloidal silvers. Used internally for immune support — taken sublingually or swallowed, or used topically. Physician-dispensed, practitioner-recommended formulation. Argentyn 23 is a physician-grade, pharmaceutical-quality bio-active silver hydrosol distributed exclusively through licensed healthcare practitioners — providing 23 ppm (parts per million) of silver in a bioelectrical silver ion form with the highest bioavailability of any commercial silver supplement. Available at Beauty Riche with same-day shipping.
