Joint Strong is a dog supplement that is designed as a 3-pronged approach to joint disorders. (1) "Puts out the fire" of inflammation with ORAC antioxidants as found in wolf diets. (2) Guards cartilage from chemical attack. Green tea extract, acetyl-cysteine and curcumin inhibit cartilage destroying enzymes. (3) Supports repair and growth. Glucosamine (1150 mg), chondroitin and CMO help "turn on" anabolic processes to support cartilage repair and growth.
