We all want our best friends to stay active and happy, and be able to run, play, and jump for years to come. Active Mobility from Terry Naturally Animal Health can help. This proprietary blend delivers a synergistic combination of glucosamine, chondroitin, type II collagen, hyaluronic acid, and our own BOS-10 boswellia.What's Inside: This powerful combination is the right choice for cartilage development, connective tissue, joint lubrication, flexibility, and mobility. Glucosamine and chondroitin work together as building blocks for maintaining healthy joint function and have been shown in multiple studies to aid mobility in dogs. Hyaluronic acid complex supports joint mobility and cartilage development. Type II collagen occurs naturally in the body and is a major component of the cartilage in the joints, also called "articular cartilage," because it is involved in the articulation, or movement, of joints. Supplemental type II collagen can help support and maintain healthy cartilage and joint function and may ease occasional stiffness and discomfort. BOS-10 boswellia (Boswellia serrata) is our unique boswellia that contains up to 10 times more of the key compound, acetyl-11-keto-beta-boswellic acid, known as AKBA, than unstandardized boswellia. This compound supports pathways in the body that other strong botanicals can't. Our BOS-10 is standardized to at least 10 percent AKBA, and virtually no beta-boswellic acid so your best friend gets the benefits they need and none of the compounds they don't.
