NEW YORK, May 6, 2026
Kingdom, a biotechnology company focused on clinically validated pet wellness ingredients, announced the publication of a second peer-reviewed study supporting the effectiveness of its Superculture® Pet Immune postbiotic ingredient in improving canine gut health. Published in the journal Pets, the placebo-controlled study demonstrated that dogs receiving the ingredient experienced significant improvements in stool quality within just 28 days, reinforcing growing scientific interest in microbiome-targeted solutions for companion animal health. The latest findings further strengthen Kingdom’s position within the rapidly expanding veterinary wellness and functional nutrition sector as pet owners increasingly seek science-backed products capable of delivering measurable health benefits.
The newly published research builds upon Kingdom’s earlier peer-reviewed study involving Superculture® Pet Immune, which previously demonstrated positive outcomes related to skin and coat health, occasional itching, and gut microbiome diversity in dogs. Together, the two studies establish the ingredient as one of the few clinically validated postbiotic solutions in the veterinary market with published evidence supporting multiple canine health benefits.
Clinical Study Demonstrates Significant Improvement in Stool Quality
The latest placebo-controlled clinical study, titled “A Novel Postbiotic Improves Stool Consistency in Dogs,” evaluated healthy dogs experiencing loose stools over a 28-day period. According to Kingdom, the results showed that 50% of dogs receiving Superculture® Pet Immune experienced measurable improvement in stool quality, compared to only 10% in the placebo group. Researchers assessed outcomes using the widely recognized Waltham Fecal Score, an industry-standard stool scoring system used in veterinary nutritional research.
The study also demonstrated that key gut health biomarkers remained within healthy ranges throughout the trial period, indicating that the ingredient improved digestive health without disrupting normal gastrointestinal balance. Parameters including fecal pH, immunoglobulin A (IgA), calprotectin, short-chain fatty acids, and dry matter composition remained stable during supplementation.

Researchers additionally observed meaningful shifts in the canine gut microbiome composition among dogs receiving the postbiotic ingredient. The treatment group demonstrated changes across 16 different gut bacterial populations, compared with only one bacterial change observed in the placebo group. Kingdom scientists stated that the findings further support microbiome modulation as a central mechanism driving improvements in digestive, immune, and skin health outcomes.
Postbiotic Innovation Expands Veterinary Wellness Market
Postbiotics have emerged as one of the fastest-growing segments within the global pet wellness industry as veterinary researchers and nutrition companies increasingly focus on microbiome-based approaches to animal health. Unlike probiotics, which contain live microorganisms, postbiotics are bioactive compounds produced during microbial fermentation that may provide health benefits while offering greater formulation stability and manufacturing consistency.
Kingdom’s proprietary Superculture® platform is designed to develop functional ingredients targeting major unmet needs in companion animal health, including gut, immune, oral, and skin conditions. Company executives emphasized that the pet nutrition industry has historically lacked rigorous clinical validation standards, creating increasing demand for evidence-based veterinary wellness solutions supported by peer-reviewed science.
According to Kingdom Chief Scientific Officer and co-founder Ravi Sheth, PhD, the company’s two published clinical studies provide measurable scientific evidence supporting the ingredient’s efficacy and differentiate Superculture® Pet Immune within a highly competitive pet wellness market. Principal Scientist Aylesse Sordillo, PhD added that achieving statistically significant stool quality improvement represents an important advancement in a category where many products have struggled to demonstrate measurable clinical outcomes.
Science-Backed Pet Wellness Continues to Gain Momentum
The publication arrives during a period of rapid expansion in the global pet health and wellness sector, where rising veterinary costs and growing consumer interest in preventive care are accelerating demand for functional nutrition products backed by scientific validation. Industry analysts continue to identify microbiome science and postbiotic innovation as key drivers shaping the future of companion animal healthcare.
Kingdom stated that its Superculture® ingredients are already being incorporated into products from more than a dozen pet wellness brands, including Dinovite, Native Pet, and Woof. One recently launched product featuring Superculture® Pet Immune was also recognized among the top pet products showcased at the 2026 Global Pet Expo.
As veterinary biotechnology and microbiome research continue advancing, clinically validated postbiotic ingredients are expected to play an increasingly important role in next-generation companion animal health strategies focused on digestive health, immune function, and preventive wellness care.
