A recent study published in the International Journal of Medical Sciences is drawing attention for its findings on resveratrol—a plant-derived compound—and its ability to protect the intestinal lining in the presence of chronic kidney disease (CKD). Conducted using both animal and cellular models, the study shows that resveratrol can reverse gut damage caused by uremic toxins, particularly indoxyl sulfate, a waste product that builds up as kidney function declines.
The Gut-Kidney Connection Gets Clearer
CKD is typically understood as a renal condition, but recent research has begun to uncover its wide-ranging effects throughout the body—including in the gut. The study found that resveratrol helped repair the gut lining by increasing important proteins that hold intestinal cells together. It also protected the cells’ energy systems and reduced signs of damage. This suggests that resveratrol may help keep the gut healthier, even when the body is under stress from kidney disease.
Why It Matters for Cats with Kidney Disease
While the study was not conducted on cats, its implications are hard to ignore. Many cats with CKD suffer from vomiting, diarrhea, and poor appetite, all of which could be linked to gut barrier breakdown. The mechanisms highlighted in the study—restoration of gut structure, support of cellular repair, and reduction of stress inside cells—mirror the types of issues veterinarians see in CKD-afflicted cats.
Greycoat Research recently published an in-depth review of the study's findings on its blog, connecting the results to feline care strategies. As a company specializing in kidney-focused support for cats, Greycoat Research has long emphasized the role of multi-pathway ingredients like resveratrol in managing CKD.

A Future for More Complete Kidney Support
Though more species-specific research is needed, the findings reinforce what many feline health experts already suspect: kidney disease management may require more than just protecting the kidneys themselves. Gut health could be a missing piece in the puzzle, and resveratrol may play a key role.

Greycoat Research’s Dr. Toru Protocol and Intensive Protocol both include resveratrol as part of their formulation—reflecting this broader approach to care that supports the kidneys from multiple directions, including the gut. With over 1,000 feline consultations to date, and 97% of stage 2 and 3 cats showing improved kidney health when following our guidance, these results reflect a philosophy grounded in research, balance, and real-world outcomes.
While no single compound can cure kidney disease, findings like this represent meaningful progress for feline kidney care. Each new piece of research helps us understand more about how to protect feline health and improve quality of life. And for cats living with CKD, even small improvements in gut or kidney stability can make a real difference.
As new discoveries reshape our understanding of CKD care, Greycoat Research continues its mission to provide data-driven CKD management solutions to cat owners worldwide.
