Hyaluronic acid (HA) is glycosaminoglycan, which is a fairly long chain of sugars (disaccharides) that are present in all connective tissues responsible for retaining moisture. Studies show that supplementing with HA has shown multiple benefits from improving skin moisture content and elasticity, assists in moisturizing the eye, but the most well-known benefit is for its joint ache relief. As we age, the level of hyaluronic acid in our bodies can drop as much as fifty percent. Genetics, smoking and deficiencies such as magnesium and zinc can all play a part to accelerate this loss, but levels of hyaluronic acid drop in all of us to some degree naturally. As these levels drop we may find ourselves with aching joints, or dry skin. Supplementing with hyaluronic acid can help promote healthy joints and skin. The most known benefit of hyaluronic acid is promoting healthy joints. The effectiveness of hyaluronic acid is not one bit surprising due to the concentrated amounts found in areas such as the knees, hips and other moving joints.
