U.S.P. <51> Antimicrobic Effectiveness Evaluation: Sovereign Silver and Argentyn 23

Both of Natural-Immunogenics Corp.'s products, Sovereign Silver and Argentyn 23 were evaluated in a nationally accepted standard test method, performed by a FDA-licensed pre-clinical testing laboratory. The standard test method employed world-wide, and considered by the FDA in assessing products for antimicrobial effectiveness claims, is the U.S.P. <51> protocol for Antimicrobial Effectiveness Testing. Five different microorganisms (representing the “microbiological spectrum” of microbe types) are employed: S. aureus, E. coli, Ps. Aerogenosa (all 3 are bacteria), C. albicans (yeast), and A. niger (mold/fungus).

Natural-Immunogenics Corp. desired to know how good their products are, so a NON-STANDARD 6 minute initial time point was employed, in addition to the 7, 14, and 28 day time points.

Both of its products, Sovereign Silver AND Argentyn 23, killed ALL U.S.P. <51> Antimicrobial Effectiveness Study microorganisms (bacteria, yeast and fungus) within only a 6 minute exposure and satisfies all criteria for all categories (from aqueous to injectables) using only a 6 minute product to microbe exposure.

Both products were challenged with 10,000 viable organisms (CFU) of each species.

Number of microorganisms surviving a 6 (six) minute exposure to Sovereign Silver and to Argentyn 23 are shown in the following graphs:
