Functional additives for pet food
Functional additives for a defined nutritional job.
Functional additives for a defined nutritional job.
Blends included for a measurable effect, not a nutritional contribution. The useful question is what was measured, and whether the claim survives the regulator.
A functional additive is an ingredient included for a specific physiological effect, not for the protein, energy, or fiber it contributes. Inclusion rates are low enough that it does not move your macros, which means the entire case for it rests on whether the effect is real and whether you are allowed to say so.
That makes this category unlike every other one we work in. With a starch, the question is what it does in your process. With a functional additive, the process question is still there, and there are two more sitting in front of it: what was actually measured, and what your label can survive.
Targeted ingredients for digestive support, immune support, and everyday nutritional gaps, selected to work alongside your core formulation rather than compete with it.
What we carry, by function
Each additive is doing one job
We work with a botanical and polyphenol-based range built for incorporation into daily wet or dry food, across four functional areas.
The gut and immune line is polyphenol compounds built on aromatic plant extracts, including thyme, cinnamon, and citrus fractions, positioned around intestinal and immune function.
For digestive performance and antioxidant load, there is a combined system of prebiotics and postbiotics, organic acids, betaine, and essential oils. The organic acid fraction is the part formulators tend to underrate: it is doing work on gut pH and microbial environment, and it interacts with anything else acid-sensitive in your formula.
The inflammatory-response blend is plant extracts and polyphenols built on the curcumin family with black pepper and ginger. Black pepper is in there for a reason, and the reason is not flavor, and it is worth asking any supplier of a curcumin-based system to explain that reason, because the answer tells you whether they understand bioavailability or are assembling a label.
The calm blend uses botanical extracts including passionflower, valerian root, and chamomile, plus tryptophan. This is the one with a measured endpoint behind it, which is discussed below.
All four run at 1 to 2 kg per metric tonne of finished food, supplied as dry powder in 25 kg multilayer bags.
A joint supplement targets one outcome, a probiotic targets another. Adding several at once because each sounds good on its own can dilute the dose of any single one, or create interactions you did not plan for. Start with the specific outcome you are formulating for, then work backward to the additive that actually delivers it at a workable inclusion rate.
Dosing at 1 to 2 kg per metric tonne is a mixing problem, not a cost problem
Dose and delivery decide whether it works
At 1 to 2 kg per metric tonne you are working at roughly one to two parts per thousand. Two things follow, and neither is the one people expect.
The cost per finished tonne is small. That is usually not the constraint.
Distribution uniformity is the constraint. A micro-ingredient at that inclusion is only as good as your batching and mixing discipline, and an additive that is unevenly distributed does not give a milder version of the intended effect. It gives a portion of the product carrying none and a portion carrying several times the intended dose. If you are adding one of these to an existing line, the honest first question is about your premix and carrier route, not about the additive.
Extrusion heat and steam can degrade a live probiotic or a heat-sensitive vitamin before it ever reaches the bag, and moisture does similar damage later, in storage rather than in the extruder. A coating applied after extrusion protects an ingredient that would not survive the cook, but only if the coating itself holds up through packaging and storage. The inclusion rate on a spec sheet means little if the additive does not survive your actual process and reach the animal still active.
Where it enters the process, and the question we ask before we answer
The right additive depends on who is eating it
This is the part we will not guess at, and it is worth explaining why.
Our technical documentation for this range gives storage conditions: keep dry, out of direct sunlight, and below 35 degrees Celsius. That is a storage figure. It says nothing about what happens in a preconditioner, a barrel at extrusion temperature, or a retort cycle.
For a system built on botanical extracts and essential oils, that distinction is the whole question. Volatile aromatic actives are exactly the sort of material that a thermal process can carry off or degrade, and “stable in the bag” and “stable through the die” are unrelated properties.
So before we recommend an inclusion point for your process, we ask the manufacturer for process-stability data for your format specifically: in-barrel, post-dryer coating, or wet-side addition. If we have not been given it, we will tell you that instead of assuming it is fine.
That is a slower answer than you will get elsewhere. It is also the difference between an additive that works and one that was measured on the bench and lost at the die.
Joint support ingredients earn their place in a large-breed or senior formula, where cartilage wear is a documented problem. Put the same inclusion rate in a formula built for small-breed puppies and you are paying for a benefit that customer does not need yet. Digestive support works the same way: a cat's gut and a dog's gut do not respond identically to the same fiber or probiotic strain, and treating species as interchangeable in a functional blend usually means one animal gets an ingredient dosed for the other's physiology. Match the additive to the life stage and species you are formulating for.
Prebiotic, probiotic, postbiotic
Where it gets harder than a label claim
These three get used interchangeably in marketing and they are not the same thing. The difference decides whether the ingredient can survive your process at all.
A prebiotic is a non-digestible substrate that feeds beneficial gut microbes. Fructooligosaccharides and mannan-oligosaccharides are the common ones. It is a food source, not an organism, so heat stability is a chemistry question, not a viability one.
A probiotic is a live microorganism, and it has to still be alive at the bowl to do anything. That makes extrusion genuinely difficult. Some strains have documented survivability through the cook, and specifying one of those is a real formulation decision, not a marketing preference.
A postbiotic is inactivated microbial cells and the metabolites they produced. Because nothing has to stay alive, thermal survivability stops being the governing constraint. That single fact is most of why postbiotics scaled through the category so quickly, and why dry food, not wet, has become their strongest delivery format.
If a supplier uses the three words loosely, that tells you something about how carefully the rest of the file was assembled.
A probiotic strain that survives on its own can lose viability next to a mineral premix, and a botanical extract stable in a dry blend can behave differently once it is wet and extruded. Shelf life is the second problem: an additive tested for potency on day one of production is not the same additive a customer feeds eight months later, and few suppliers publish real degradation curves past the point their own guarantee ends. None of this shows up on a single ingredient spec sheet, because a spec sheet describes the ingredient in isolation, not the formulation and the shelf life it has to survive.
What was measured, and what we will say about it
Most calming and functional ingredients in this category offer a mechanism. Very few offer a measurement.
The calming blend in our range has a controlled feline study behind it, measuring serum cortisol as the endpoint at an inclusion of 2 kg per metric tonne in a trial of 30 adult cats. Cortisol is a useful endpoint precisely because it is a number: it is what a regulator, a customer’s quality team, and a skeptical formulator can all look at.
What we will not do is translate that number into a claim it does not support. A measured change in a stress-related biomarker is a defensible statement. A statement about an animal’s emotional state, or about relieving a named condition, is a different kind of statement, and in US and Canadian feed regulation it can push a feed ingredient toward being regulated as a drug.
That is not a style preference. Claims that describe treating or preventing a condition change the regulatory category of the product, and the manufacturer’s brochure language is written for a European consumer-brand audience, not for a North American label review. Several phrases in that material describe eliminating emotional or behavioral conditions, naming specific conditions, or promoting sleep. None of them appear anywhere in what we will put in front of you, and none of them should appear on your pack.
Confirm claim language for your own market before you formulate. We will tell you what was measured. Your regulatory review decides what can be said about it.
We do not sell functional additives as a category. We work through the specific claim you are trying to support: what has to survive your process, and what animal it actually has to work for. Samples and stability data come from the supplier, and we will tell you plainly when an inclusion rate on a spec sheet has not been proven in a system like yours.
How to judge a functional additive
Six questions, in the order worth asking them.
1. What was measured, in which species, and how many animals? A mechanism is a hypothesis. A biomarker is evidence. Ask which one you are being sold.
2. Was the study independent, or the supplier’s own? A supplier’s own trial is not disqualifying and it is not the same as independent replication. Know which you have.
3. What is the claim language approved for this market? Not the brochure language. The approved language, for your jurisdiction, in writing.
4. What happens to it in my process? Storage stability and process stability are different properties. Ask for the second one specifically, by format.
5. How does it get distributed evenly at this inclusion? Premix, carrier, mixing time. At one to two parts per thousand this is the real execution risk.
6. What else in my formula does it interact with? Organic acid systems move pH. Essential oils can affect palatant performance. Neither is a reason to avoid them, both are reasons to test instead of assuming.
Where we fit
We are not going to hand you a brochure and let your regulatory team discover the problem. What we will do is tell you what was measured, what the documentation actually covers, and where the gaps are, including the gaps in our own file.
If you are evaluating a functional additive from any source, the fastest way to find out whether it is real is usually to read the file together.

Common questions
What is the difference between a prebiotic, a probiotic and a postbiotic?
A prebiotic is a non-digestible substrate that feeds beneficial gut microbes, such as fructooligosaccharides or mannan-oligosaccharides. A probiotic is a live microorganism that has to still be alive at the bowl to work, which makes extrusion difficult. A postbiotic is inactivated microbial cells and their metabolites, so nothing has to survive the cook. That is why postbiotics scaled quickly in dry food.
At what rate are functional additives included in pet food?
Botanical and polyphenol-based functional systems typically run at low single-digit kilograms per metric tonne of finished food, which is roughly one to two parts per thousand. Confirm the rate against the specific product’s technical documentation. At that inclusion the practical risk is distribution uniformity in mixing, not cost.
Do botanical additives survive extrusion?
It depends on the system and it should never be assumed. Storage stability and process stability are different properties, and technical sheets often give only the first. Botanical and essential-oil actives are volatile by nature, so ask the manufacturer for process-stability data for your specific format: in-barrel, post-dryer coating, or wet-side.
Why can’t a pet food additive claim to reduce anxiety?
In US and Canadian feed regulation, a statement about treating or preventing a condition can push a feed ingredient toward being regulated as a drug instead of a feed ingredient. A measured biomarker, such as a change in serum cortisol, is a defensible thing to describe. A statement about an animal’s emotional state or a named condition generally is not. Confirm approved claim language for your market before it goes on pack.
What should I ask a supplier about a functional additive?
What was measured, in which species, and in how many animals. Whether the study was independent or the supplier’s own. The approved claim language for your jurisdiction, in writing. Process-stability data for your format. How it distributes evenly at its inclusion rate. And what it interacts with in your formula, particularly pH-sensitive and palatant systems.
