17TurmericTurmeric / curcumin▾
● Beneficial (emerging)Curcumin has well-documented anti-inflammatory properties in laboratory studies, but its bioavailability in standard oral forms is poor without specific enhancement (piperine, lipid carrier, or phytosomal formulation). In several randomised controlled trials in dogs and cats with osteoarthritis, diets and supplements containing bioavailability-enhanced curcumin (for example phosphatidylcholine/phytosome complexes), usually combined with other ingredients such as omega-3 fatty acids, hydrolysed collagen or green-lipped mussel, were associated with owner- and veterinarian-reported improvements in pain and mobility (e.g. Comblain et al., 2017); objective gait measures were often unchanged, and these effects have not been demonstrated for the small amounts of plain turmeric found in most foods.Sources: Colitti et al. 2012 · Comblain et al., BMC Veterinary Research 2017, DOI 10.1186/s12917-017-1317-8 · Feline osteoarthritis diet with EPA/DHA, turmeric extract and hydrolysed collagen, Animals 2024;14(22):3298 · Moreau et al., Veterinary Record 2003;152(11):323 (counter-evidence: curcumin nutraceutical did not improve objective gait vs NSAIDs) · Pye et al., Journal of Small Animal Practice 2024 (review)Position on the ingredient list suggests a small inclusion level.
18Chamomile▾
● Beneficial (emerging)Chamomile (typically German chamomile, Matricaria chamomilla) is traditionally used as a calming and digestive herb, with constituents such as apigenin and bisabolol studied mainly in humans and laboratory models; controlled studies in dogs and cats are limited and much of the pet evidence is anecdotal. Veterinary sources associate it with soothing mild digestive upset and mild anxiety in dogs when used in moderation. Cats appear more sensitive, and high doses or prolonged use have been linked to hypersalivation, appetite loss, or contact dermatitis, so veterinary guidance is advised.Sources: VCA Animal Hospitals, 'Chamomile' veterinary information sheet · NCCIH, chamomile (Matricaria) overview (human/traditional use) · Whole Dog Journal / Great Pet Care veterinary-reviewed chamomile articlesPosition on the ingredient list suggests a small inclusion level.

Note: English pennyroyal (Mentha pulegium) is a different mint species that IS toxic to dogs and should not be confused with spearmint.Sources: ASPCA non-toxic plant list · Dog Food Advisor mint guide · Continental Kennel Club
