Natural Source International Ltd. is a leading provider of cutting-edge natural supplements, developed by the late Dr. Mirko Beljanski, that are designed to support immune system health. The Beljanski® products are supported by 133 peer-reviewed articles published during Beljanski’s lifelong research at the Pasteur Institute in Paris, France. Today his daughter Sylvie continues his legacy as president of Natural Source International, Ltd. in the United States. Dr. Beljanski’s research has attracted the attention of two prestigious institutions, Columbia University and Cancer Treatment Centers of America, which are conducting clinical trials on two of the Beljanski® products. The former is working with Prostabel® to improve prostate health, while the latter is working with ReaLBuild® which is being shown to support platelet and white blood cell proliferation. Both studies are yielding promising results, validating the company’s motto, “Sourced from nature…perfected by science!”
