Triple-action formula that helps to support mobility, maintain flexibility and promote the comfort of your joints. New stronger formula with vitamin D for healthy bones. How It Works: Glucosamine and chondroitin are naturally occurring components of cartilage, the connective tissue that serves as a cushion between your joints. Hyaluronate is a naturally occurring compound found in joints and connective tissue. It is important to support healthy joint cartilage to help maintain joint comfort and flexibility. New maximum strength Trigosamine delivers well-researched levels of glucosamine and chondroitin, which have been found to support joint comfort, mobility and flexibility. This advanced formula also contains hyaluronate, providing you with a triple-acting formula to help support healthy joints. An added 1000 IU of vitamin D helps to provide support for strong bones, making Trigosamine a well-rounded joint support formula.
