Nutrihyl® Sodium Hyaluronate is a branded active ingredient of biotechnological origin that has been shown by various clinical studies to promote joint health in human and animal subjects. Hyaluronic acid is a special mucopolysacharide that exists naturally in all living organisms. In the human body, it is found in greatest concentrations in the synovial fluid of articular joints (where it is used for lubrication), in the vitreous humor (fluid) of the eye, and most abundantly in the skin. As we age, the body's natural production of hyaluronic acid decreases, often causing stiffness and pain in the joint and producing dryness & wrinkles in the skin. Since hyaluronic acid is essential to tissue hydration, lubrication and cellular function, its benefits as a nutritional supplement ingredient have been widely recognized.
