Answer:Some small studies have suggested that curcumin may reduce markers of inflammation in dogs and cats, but studies have not shown a direct benefit on the symptoms of osteoarthritis in pets. Curcumin appears to be safe for dogs and cats, but be aware that, as with people, there are safety concerns with certain medications and medical conditions — as well as with an absorption enhancer found in some formulations.

Although ConsumerLab.com has not tested curcumin supplements for pets, we have tested other Joint Health Supplements for Pets (with glucosamine and chondroitin).
Tests of other pet supplements for other uses can be found within larger reviews focusing on supplements for people, including Multivitamins, Fish Oil and Omega-3 Fatty Acid Supplements, and Seed Oils (Flaxseed, Evening Primrose, and Borage), SAMe, and Probiotics.
