Turmeric extract clears a feline safety test in new study

Turmeric extract appears well tolerated in healthy adult cats, according to a new Animals study from researchers at Royal Canin and Mars Petcare. In the four-month, randomized, blinded tolerance trial, 45 cats were assigned to a control diet or to one of two diets supplemented with turmeric extract, with the highest dose providing up to 1040 ppm total curcuminoids. Investigators tracked body weight, body condition score, food intake, fecal score, adverse events, CBC, and serum biochemistry, including liver enzymes, and reported no statistically significant findings of clinical or toxicological concern. The authors said the results support turmeric extract’s safety at that level and could help support its future use as a nutritional antioxidant in cat food. (studocu.vn)

Why it matters: For veterinary professionals, the study adds a piece that has been missing in feline nutrition: target-animal tolerance data for a turmeric-derived ingredient that’s already drawn interest for antioxidant and anti-inflammatory potential. That matters because turmeric and curcumin have been explored in companion animals, including in a 2024 cat osteoarthritis diet study, but practical use in formulated diets depends not just on efficacy signals, but on safety data robust enough for regulatory review and product development. The new paper also underscores a familiar caveat: these were healthy adult cats in a controlled feeding study, so the findings don’t establish clinical benefit, long-term safety beyond four months, or safety in kittens, seniors, or cats with hepatic, GI, or other comorbidities.

What to watch: Watch for whether these data are used in regulatory submissions or commercial diet formulations, and whether follow-on studies test efficacy, longer-term exposure, or use in cats with specific clinical conditions. (studocu.vn)
