Kingdom, a supplier of postbiotic ingredients for pet health applications, announced the publication of two peer-reviewed studies on Superculture Pet Oral. The studies bring the total peer-reviewed publications on the ingredient to three, following an earlier study published in Animals.
The first study, "Canine halitosis improved with a postbiotic, a validation study," examined the ingredient at a lower daily dose. Results showed a 26% reduction in bad breath compounds compared to a placebo group within 14 days. Dogs in the placebo group experienced a 38% increase in odor-causing compounds over the same period. The company said higher doses achieved comparable results within 7 days.
The second study, "A postbiotic positively shifts the canine oral microbiome," used metagenomic analysis to quantify volatile sulfur-producing colonies and measure changes in oral bacteria. Findings included a reduction in abundance of nine times as many pathogen-associated bacteria compared to the placebo group within 7 days. Six of the nine reduced bacterial types were associated with oral biofilms linked to bad breath. The study also found a trend toward a 44% reduction in odor-causing bacterial colonies by day seven.
"The pet industry is increasingly adapting to the humanization of pets, with pressure for real, quality products and not just marketing language," said Ravi Sheth, co-founder and chief scientific officer at Kingdom. "Human and pet health standards are converging. Biotics are no longer just a buzz word, but a performance category recognized for their measurable improvements. For both themselves and their pets, people want ingredients with visible results backed by clinical evidence."
"Pet parents are increasingly skeptical of products that promise results but don't deliver anything noticeable," said Aylesse Sordillo, principal scientist at Kingdom. "What sets this research apart is that it connects rigorous clinical data with results people can actually see — and smell — in their pets, like fresher breath within weeks."
Superculture Pet Oral is currently used in products from brands including Dinovite, Native Pet and Woof. Kingdom said it now has five peer-reviewed clinical studies across its Superculture ingredient line.
