Decades of Immune Health Support

Stellar Biotics & del-IMMUNE V

Stellar Biotics LLC (formerly Pure Research Products, LLC) was established in 2002 and is dedicated, to the research and development of immune-oriented nutraceutical supplements for humans and pets. Its products are created by Dr. Liubov Sichel, leading microbiologist, co-founder and chief scientific officer (CSO) of Stellar Biotics LLC, who formulated them based on the latest science supporting the microbiome, microbiota, probiotics, and the newest metabiotics and postbiotics concepts.

Its immune supplement products are developed using unique probiotic cultures, advanced Cell Fragment Technology™ and phytonutrients as prebiotics for host microbiota and probiotics. They work via immune cell receptors to help regulate the immune response.

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. del-IMMUNE V is a bioactive metabolite and cell structural substance (muramyl polypeptides and DNA motifs), derived from the cell of a selected probiotic strain,“ Lactobacillus rhamnosus DV.” Scientific studies have shown that del-IMMUNE V components can interact with certain immune cells, including cells producing secretory immunoglobulin A (sIgA), interferons (IFNs) and other immune mediators, known to play a critical role in healthy immune system function. del-IMMUNE V replicates the process that occurs naturally in the human body, between healthy microbiota and immune receptors. These interactions are realized in immune signal production and helps the innate immune system protect the body against all kinds of pathogens and threats, including stress.

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 DPS Throat Spray which contains peptides from bovine colostrum to regulate the immune system.

We sell solely online to consumers either directly through our company website, Amazon or through healthcare practitioners and providers. The full line of our immune products are made and manufactured in the United States and available to customers world-wide.

Dr. Sichel continues to collaborate on scientific and clinical research with companies and universities in the United States, Canada, Ukraine, Bulgaria, and Poland to support the development of new formulations that combine del-IMMUNE V with other recognized and innovative therapeutics.
