The probiotic promise vs. the manufacturing reality

‍The companion animal industry is increasingly embracing postbiotics, and for good reason. Two key drivers are accelerating the shift: postbiotics offer superior stability through manufacturing and shelf-life, and greater consistency of benefit delivery.

Here's a useful way to think about it. Prebiotics are the fuel: substrates that feed beneficial microorganisms. Probiotics are the factories: live microorganisms intended to confer a health benefit. Postbiotics are the finished goods. They deliver the beneficial compounds directly.

That distinction between "factory" and "finished goods" may sound subtle, but it has enormous implications for production, performance, and shelf-life. To understand why, it helps to start with the challenge that probiotics present to formulators.

Why live organisms and pet product manufacturing don't easily mix

Probiotics are living organisms. They're sensitive to manufacturing conditions like heat, pressure, moisture, and pH.

This creates a fundamental tension: the very manufacturing processes used to make pet products (extrusion, baking, retort, and others) can degrade or kill the active ingredient. The process that creates the product can compromise the ingredient that's supposed to make it work.

Brands then face a difficult choice: over-formulate to compensate for loss, limit product formats to protect viability, or accept inconsistent potency across batches and shelf-life. None of these are great options, and all of them introduce cost, complexity, or risk to the brand's reputation with pet parents.

What postbiotics are and why they're gaining traction

Postbiotics consist of inanimate microbes and beneficial metabolites. They're not alive, and that changes everything from a formulation standpoint.

Our Superculture® postbiotics are stable under the temperature, pressure, and moisture conditions encountered during common manufacturing processes. This unlocks formulation flexibility across virtually every pet product format:

• Injection molded chews
• Extruded chews
• Semi-moist and wet food
• Liquids and water additives
• Powder toppers
• Dried kibble

No CFU counting challenges. No cold chain requirements. No over-formulating to compensate for loss.

And stability doesn't stop at the production line. Validated stability means retaining efficacy through the full product lifecycle: production, shipping, shelf-life, and in the animal. Superculture® ingredients have been extensively tested and verified as stable under the constraints of common manufacturing processes. Both ingredients also have validated stability in conditions mimicking the oral cavity and saliva (pH 7–9), and Superculture® Pet Immune has demonstrated stability in gastric and intestinal fluids (pH 1.5–8.5 for 6+ hours).

For brands, this means the active ingredient that goes into the product is the same active ingredient that reaches the pet.

Not all postbiotics are equal: here's what to look for

The postbiotic category is growing fast, but "postbiotic" on the label doesn't tell you much about what's inside or whether it works.

When evaluating postbiotic ingredients, there are a few critical questions worth asking:

• Was this ingredient designed for companion animals? Repurposed ingredients from human or livestock applications may not deliver the same results in dogs and cats.
• What clinical evidence exists, and in what species? In vitro data and owner perception surveys are a starting point, but they aren't a substitute for controlled clinical trials in the target species.
• Are the studies rigorous? Look for placebo-controlled, double-blinded, randomized study designs, and peer-reviewed published research.
• Can the ingredient withstand your manufacturing process? Stability data should cover the specific conditions of your product format, not just general manufacturing stability and shelf-life claims.
• Does the data show a quantifiable, consumer-noticeable benefit? Results that pet parents can actually see, in days or weeks rather than months, are what drive repurchase and reviews. The gap between a marketing claim and a noticeable impact is where brand trust gets built … or lost.

What clinical validation actually looks like

Our Superculture® postbiotics were designed from the ground up specifically for companion animals. They aren't repurposed from another species or another application.

They are validated in clinical studies that are:

• Placebo-controlled: comparing against a true control, not just a baseline
• Double-blinded: neither the researchers nor the pet parents know who received the active ingredient
• Randomized: eliminating selection bias
• Peer-reviewed and published: scrutinized by independent scientists

Across these studies, Superculture® ingredients have been shown to outperform alternatives head-to-head, with best-in-class data across bad breath, oral microbiome health, itch reduction, skin and coat quality, and stool quality improvement. Nine completed clinical studies demonstrate noticeable results in 7–28 days, the kind of timeline where pet parents notice a real difference. Two more studies are in progress.

That's the distinction between riding a category trend and delivering real, measurable results.

The bottom line

Our clinically-validated postbiotics deliver consumer-relevant benefits and superior stability profiles, enabling formulation flexibility, consistent efficacy, and claim integrity.

For brands, this means the ability to innovate across product formats without worrying about whether the active ingredient survived the process. For pet parents, it means the product they buy actually delivers on marketed claims.

The bar for pet health ingredients is rising. Science-backed, clinically proven benefits are no longer "premium." They're table stakes. Superculture® postbiotics give brands the head seat at that table.
