A Tolerance Study of Turmeric Extract in Healthy Adult Cats

Area of Science:

• Veterinary Science
• Animal Nutrition
• Toxicology

Background:

• Turmeric extract (TE), rich in curcuminoids, is recognized for antioxidant properties.
• Interest in TE for companion animals is growing, but cat-specific safety data is limited.
• Regulatory approval for TE in pet food requires comprehensive toxicology studies.

Purpose of the Study:

• To evaluate the safety and toxicological profile of turmeric extract (TE) when supplemented in the diet of domestic cats.
• To establish safe dietary levels of TE for potential use as a nutritional antioxidant in cat food.

Main Methods:

• A four-month feeding study involving control cats and two groups of cats fed diets with different levels of TE.
• Comprehensive monitoring including physical examinations, body weight, food intake, and hematological and biochemical blood analyses.
• Assessment of clinical signs, adverse effects, and fecal scores to detect any toxicological concerns.

Main Results:

• No statistically significant adverse effects were observed in cats receiving TE supplementation.
• Clinical and toxicological parameters, including liver enzymes, remained within normal ranges across all groups.
• Feeding TE up to 1040 ppm total curcuminoids in the diet was determined to be safe for cats.

Conclusions:

• Turmeric extract (TE) is safe for feline consumption at dietary levels up to 1040 ppm total curcuminoids.
• The study provides crucial safety data supporting the potential use of TE as a nutritional antioxidant in cat food.
• Further research can now explore the efficacy of TE in feline health and nutrition.
