About us

Leading microbiologist, Dr. Liubov Sichel, founded Stellar Biotics LLC (formerly Pure Research Products, LLC) in 2002, for the research and development of immune-oriented nutraceutical supplements for humans and pets.
Using unique probiotic cultures, Cell Fragment Technology, and phytonutrients as prebiotics, Dr. Sichel created supplements that work via immune cell receptors to help regulate the immune response. These supplements, called metabiotics, are based on the latest postbiotics research and are the next generation of probiotics.
We are most-widely known as the maker of del-IMMUNE V - the leading non-prescription cell fragment supplement backed by clinical research on the U.S. market. We develop other products which combine del-IMMUNE V, including our probiotic, delPRO, and our four pet products, which combine del-IMMUNE V with probiotics and other ingredients, to address distinct pet health needs. We also produce Daily Throat Remedy.
