The UltraCruz Canine Advanced Joint Supplement for Dogs is a joint supplement for dogs that provides key ingredients in a balanced formula designed to support healthy joints and connective tissue. The unique combination of ingredients have been carefully selected to provide factors for bone development and building connective tissues. Chondroitin Sulfate and Glucosamine work together to support new and existing cartilage. Hyaluronic Acid (HA) is a component of synovial fluid in the joint capsule and surrounding supportive tissues, and helps to lubricate the joint. MSM (Methylsulfonylmethane) is a source of sulfur that has been shown to provide building blocks for cartilage.
