The biggest problem with the FDA information is that they ignore the fact that not all silver products (including Utopia Silver) are gelatinous based and comprised of very high ppms. When colloidal silver is produced in a gelatinous base, it is because the silver particles are too large to stay in solution and would fall out if they were in water. The gelatin helps to keep the large silver particles suspended. These products as a rule generally contain a very high ppm content of silver in order to be effective. Our products are low ppm, but are just as effective or more because of their smaller particle size. Advanced Colloidal Silver is not a salt, iodide, nitrate, protein, or gelatinous based product. Advanced Colloidal Silver is simply trace mineral and distilled water.
