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.Other products from HerbsPro
