Helping pets stay healthy for longer — through lean body condition, brain-supporting nutrients and new research on cellular energy (NAD+) and senescent cells.
The best-evidenced longevity lever: keeping pets lean throughout life.
MCTs, antioxidants and omega-3s that support brain function in senior pets.
NAD+ precursors — an early-evidence area we assess ingredient by ingredient.
Protein, energy and texture adapted to older dogs and cats.
“Supports healthy ageing” and “supports cognitive function in senior pets” — never “extends lifespan”, which is a drug claim.
Peer-reviewed studies in dogs and cats — including where evidence is limited — and how each one shapes our formulation.
In a lifetime study of 48 Labradors, dogs fed 25% less had a median lifespan of 13.0 vs 11.2 years, and late-life disease started later.
Energy control and body-condition guidance are the foundation of every ageing product.
Aged beagles fed 5.5% MCT oil for 8 months performed significantly better on most cognitive tasks.
MCT levels and oxidation stability are designed into senior recipes.
A randomised trial in 70 senior dogs found an NAD+ precursor plus a senolytic improved owner-rated cognition, but objective tests showed no difference.
Longevity actives are treated as early-evidence ingredients with careful claims.
Species, life stage, format and the benefit you want — checked against the published evidence.
Active levels and draft claims agreed per market before formulation.
Recipe built to nutrient profiles, with actives at evidence-based levels.
Actives measured in the finished product and through shelf life.
Palatability and, where claims need it, efficacy studies with partner panels.
Label, claim substantiation file and technology transfer.
Sets nutrient and active targets against AAFCO and FEDIAF profiles.
Reviews clinical relevance, safety and claim boundaries.
Designs studies and reviews the published evidence.
Checks ingredient status and claim wording in each market.
Stay ahead with regulation updates, the latest research, ingredient spotlights, recalls and market trends for functional 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 format and the markets — we will come back with an evidence-based development plan.
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.
