Rosemary extract

Also appears on labels as: rosemary, organic rosemary extract, rosemary leaf extract, oil of rosemary, rosemary ext act

Concentrated plant extracts high in natural antioxidant compounds.

Watched ingredients get highlighted on every product panel you open.

Where it comes from
Herb farming and solvent or steam extraction.
Why it's in the product
A natural preservative that slows fat oxidation, and a way to avoid listing BHA or ethoxyquin.
Safety and toxicity
Generally recognized as safe at the levels used. There is an old, poorly-supported claim that rosemary triggers seizures in epileptic dogs. It traces to concentrated rosemary essential oil, not the tiny extract dose in kibble, and mainstream veterinary sources do not treat it as a real risk. Mentioned here because owners of seizure-prone dogs ask about it constantly.

General reference, not veterinary advice. Dose, breed, and existing conditions change the answer, so talk to your vet before changing what your pet eats. Think we got this wrong? Tell us and we log it publicly.
