As the body ages we produce less haluronic acid. Haluronic Acid nourishes the cartilage as well as allows the cartilages to articulate with less friction slowing the degenerative process. It is most commonly used to treat and slow down osteoarthritis of the knee. This process is covered by most insurance when medically necessary. An X-ray of the knee is necessary to rule in or our osteoarthritis of the knee. There are many Brand name suppliers of Haluronic Acid.
