Joint & Tissue Pro features targeted nutritional support for joints and connective tissue. This formula has been specifically designed to promote healthy cartilage strength and resilience. It contains glucosamine, a natural compound found in all body tissues, which is the fundamental building block required for the synthesis of glycosaminoglycans such as chondroitin sulfate. Chondroitin sulfate is the primary structural compound of cartilage and helps block the activity of damaging enzymes. Glucosamine and chondroitin sulfate play a synergistic role in supporting healthy hyaluronic acid content and synovial fluid.
