Glucosamine and chondroitin have long been used in combination to support joint health. Glucosamine is essential to connective tissue such as collagen, the bone matrix and mucous membranes, and helps restore the thick lubricating fluids around joints. Chondroitin is found in joint cartilage and aids in the lubricating and rebuilding process. Formula 707 for humans Joint Essentials™ is carefully formulated to give you just the right amount of each to maintain joint health.
