From digestive health to healthy ageing, and from novel proteins to postbiotics — we develop the benefit and prove the ingredient, within the claims your market allows.
Functional products are built from the evidence for each ingredient and the level it is used at, then worded as nutrition claims, not disease claims.
Fibre blends, prebiotics, probiotics, postbiotics and highly digestible proteins.
Measured by digestibility and stool-quality scoring
Explore Digestive Health →Antioxidant vitamins, beta-glucans, colostrum and probiotics.
Wording such as “supports natural defences” — not medical claims
Explore Immune Support →EPA and DHA, glucosamine, chondroitin, green-lipped mussel, collagen and weight control.
Evidence review and active-level design
Explore Joint & Mobility →Omega-6 and omega-3 balance, zinc, biotin and B vitamins, protein quality.
Fatty-acid profile and stability testing
Explore Skin & Coat →Energy density, protein-to-energy ratio, fibre for satiety and precise feeding guides.
Calorie-content claims follow defined thresholds (e.g. “light”)
Explore Weight Management →Controlled minerals, target urine pH and higher moisture intake — especially for cats.
Mineral balance design; disease claims stay with veterinary diets
Explore Urinary Health →Chew and kibble texture for mechanical cleaning, plus functional ingredients.
Plaque and tartar claims need recognised protocols (e.g. VOHC)
Explore Oral Care →Ingredients such as L-tryptophan, L-theanine and milk-protein hydrolysates.
Evidence varies by ingredient — reviewed before inclusion
Explore Calm & Behaviour →Cellular energy (NAD+ precursors), senescent-cell research, cognition support (MCTs, antioxidants, omega-3s) and senior diets.
Early evidence: one controlled dog trial of an NAD+ precursor plus senolytic improved owner-rated cognition. Claims stay at “supports healthy ageing” — never “extends lifespan”.
Explore Longevity & Healthy Ageing →Puppy, kitten, gestation and lactation diets, including large-breed puppies.
Growth profiles, with calcium limits for large-breed puppies
Explore Growth & Reproduction →For ingredient companies and brands: we put new ingredients into real dry, wet, treat and supplement recipes, and measure what happens.
Meat, fish, insect, plant and single-cell proteins.
Beet pulp, cellulose, inulin, FOS and MOS.
Animal fats, fish, algal and plant oils.
Live cultures and heat-treated postbiotics.
Joint, calming and antioxidant actives.
Liquid and dry palatants, digests and flavour systems.
Nicotinamide riboside (NR), nicotinamide mononucleotide (NMN), niacin forms and senolytic flavonoids such as quercetin and fisetin.
Vitamin–mineral premixes built for your recipe, plus antioxidant programmes to control oxidation.
Wording such as “supports joint health” or “supports digestive health”, backed by evidence for the ingredient at the level used.
Medical or disease-related claims generally make a product a drug or veterinary product. We keep your wording on the right side of that line.
The same benefit can need different wording in India, the US, the EU, the UK and Australia. See our regulatory support.
Peer-reviewed and regulatory findings that shape how we work — each linked to its source.
A 2022 meta-analysis of 72 trials found clear evidence for omega-3s in canine and feline osteoarthritis, but “a very marked non-effect” for chondroitin–glucosamine.
Evidence reviews come first, so studies target ingredients and doses that can work.
A systematic review rated omega-3-enriched diets as having the highest strength of evidence in dogs; results for green-lipped mussel were positive but inconsistent.
We rank actives by evidence strength and tell you where it is weaker.
A systematic review of 17 dog studies found only a very limited effect of probiotics in acute gut disease and no added benefit over diet in chronic disease.
We don’t rely on a probiotic alone for a digestive claim — the whole recipe does the work.
Stay ahead with regulation updates, the latest research, ingredient spotlights, recalls and market trends for functional pet nutrition — written by our formulation, testing and regulatory teams.
Every project at Guires Pet Nutrition Lab runs inside an ISO 9001:2015 certified quality system and FSSAI-licensed operations, with documented methods, calibrated instruments, traceable raw materials and reviewed reports — so the results behind your product can be checked and defended.
Tell us the pet, the benefit and the ingredient — we will come back with a development route.
Every Guires PNL product is formulated to comply with the FEDIAF Nutritional Guidelines and the AAFCO Dog and Cat Food Nutrient Profiles. Neither body issues certificates to manufacturers, so compliance is verified independently against their published standards — and every product comes with a complete documentation package for regulatory submissions in the EU, US, Australia and Asian markets.
