Hyaluronic Acid is present in every tissue of your body and it is needed to perform many important functions. It is actually a glycosaminoglycan or GAG which is a substance that is produced in your body which attaches to the collagen and elastin which together forms cartilage. It is the hyaluronic acid that keeps the cartilage strong and flexible which in turn cushions the joints in your body and keeps them strong. It also increases the synovial fluid which helps to keep the joints in your body lubricated. Also, it is able to deliver important nutrients to and from cells that do not necessarily have a blood supply such as those in the cartilage. Without enough hyaluronic acid the joints can break down and deteriorate. It can be found in large concentrations of extracellular matrix which is the fluid filled spaces in between the cells in which it locks in the moisture keeping collagen moist which gives your skin a more youthful appearance. When it comes to cosmetic reasons, by taking hyaluronic acid you are actually hydrating your skin which allows it to appear more youthful and radiant looking. It also helps to heal wounds more quickly which in turn reduces scars and helps old scars heal better. It can also help by reducing the formation of wrinkles which give you a more aged look. More importantly than cosmetic benefits though it can also be an effective treatment for osteoarthritis and rheumatoid arthritis. Studies have shown that over 80% of patients taking hyaluronic acid for various types of arthritis can have significant relief of pain associated with the arthritis. By taking a hyaluronic acid supplement you can contribute to better health in your joints and muscles as well as better looking skin. There are no side effects and it is a safe product. It is recommended for people as they age because the body makes less and less hyaluronic acid as you get older.
