Santa Barbara Nutrients’ Scientists Awarded Breakthrough Patent Related to Polycystic Kidney Disease.

SBN Scientists Awarded US Patent for PKD Breakthrough

University of California professor Dr. Thomas Weimbs, a recognized leader in the Polycystic Kidney Disease (PKD) research field, and Dr. Jacob Torres, Head Researcher of Santa Barbara Nutrients (SBN) discovered that a combination of two natural compounds – Beta-hydroxybutyrate (BHB) and citrate – has a synergistic effect in halting the progression of PKD in animal models.

The patented technology was initially developed by Dr. Weimbs and Dr. Torres at the University of California, Santa Barbara. SBN has the exclusive worldwide license to commercialize patent claims covering the use of BHB and BHB/citrate in PKD and other renal indications, including chronic kidney disease (CKD) in humans and animals. Weimbs and Torres identified distinct PKD mechanisms that can be targeted by the unique formulation of two safe, non-prescription ingredients: BHB and citrate. These bioactive ingredients were shown to be effective in preserving kidney structure and function in animal models of PKD.

“We are pleased that the U.S. Patent Office has recognized our unique research in understanding a complex disease like PKD. This is an important step in our company’s effort to bring affordable products to market that can bring hope to millions of people with PKD around the world,” said Dr. Weimbs, President and Founder of Santa Barbara Nutrients. PKD is one of the most common, life-threatening genetic diseases, causing kidney enlargement and function loss over time. 

The disease affects over 600,000 Americans and 13 million people worldwide and is one of the leading causes of kidney failure requiring dialysis or kidney transplantation. There is no cure, and for most people with PKD, no treatments are available to slow down the progression of the disease. The granted patent is US Patent No. 11,013,705 titled “Methods and Compositions for Supporting Renal Health”. The Company also has exclusive rights in additional pending patent applications worldwide.
