From the Manufacturer's Label:
Hyaluronic Acid is a lubricant present in every tissue of the body, with the highest concentrations occurring in connective tissues such as skin and cartilage. As a constituent of joint fluid, Hyaluronic Acid also serves as a lubricant and plays a role in resisting compressive forces. Our formula combines this essential component with Vitamin D and other nutrients that are essential for the formation of collagen found in cartilage and connective tissue to support optimal joint health.**
