Cosequin is the number one vet recommended joint health supplement for pets. As dogs age, it’s common for them to develop stiff joints. Additionally, large breed dogs often develop joint stiffness at earlier ages than pet owners may realize. Cosequin helps to actually improve joint health and mobility. The main ingredients in Cosequin ( glucosamine chondroitin sulfate and manganese) work together to rebuild and strengthen the cartilage and synovial fluids in your dog’s joint’s. While there are other joint care supplements on the market, Cosequin’s unique combination of ingredients has been proven by controlled US studies to provide the most bioavailable, effective and safe joint support for your pets.
