About Kingdom
Kingdom creates and sells natural functional ingredients that actually work. We call these Superculture® ingredients – a new class of postbiotics made from natural microbes, that we intentionally design to make a quantifiable impact on unmet pet health needs, and to address these needs at their root.
Our first Superculture® ingredients for oral health and immune health are available now, with a number of leading pet brands already incorporating them into their end products, and a dozen more planning launches in the next twelve months.
Existing ingredient solutions mask underlying pet health needs, address them only at a surface level, or have associated negative effects. In contrast, Superculture® ingredients target these pet health needs at their root and do so in a deliberate manner that can be quantitatively validated. This enables our partner pet brands to create end products that significantly outperform existing approaches.
Since our Superculture® ingredients are postbiotics, they circumvent the viability challenges of probiotics, by directly delivering the beneficial metabolites and compounds to the desired site of action. This offers enhanced shelf-stability and more consistent performance compared to probiotics.
We manufacture Superculture® ingredients at large commercial scales and supply them to leading pet brands. They are made from natural microbial strains that fall under existing AAFCO direct fed microbials. Our Superculture® ingredients also have verified stability under challenging temperature, pressure, and moisture constraints, making them compatible with a wide range of product formats including (but not limited to) injection-molded chews, extruded chews, powder toppers, dry kibble, and wet food.
Our Superculture® Pet Oral ingredient is the market’s most clinically validated oral health postbiotic, delivering industry-leading efficacy across three clinical trials. As the first postbiotic clinically proven to target the unwanted microbes that drive bad breath, plaque buildup, and poor oral health in dogs, it represents a breakthrough in pet dental care.
Purpose-built to improve oral health without abrasion, this innovative ingredient acts directly on the oral microbiome even with brief exposure – making it ideal for pets who resist traditional dental routines. With three clinical trials and published peer-reviewed research, Superculture® Pet Oral sets a new standard for science-backed oral care that actually works.
Our Superculture® Pet Immune ingredient is the only clinically validated postbiotic shown to address pet parents’ top health concerns: occasional itching and digestive wellness. In just 28 days, two clinical trials demonstrate what no other postbiotic has achieved – significant reduction in occasional itching, visible coat quality improvement, increased gut microbiome diversity, and improved stool quality.
While other postbiotics show limited or no clinical effect on these critical endpoints, Superculture® Pet Immune delivers unprecedented results across all four. With two completed clinical trials (the first published in a peer-reviewed publication) and three more planned for 2025, Superculture® Pet Immune represents a new standard in evidence-based pet health innovation.
