The only approved use of hyaluronic acid is for injections
into a joint. They coat the inner joint and offer some "padding".
The hyaluronic acid disappears in five to nine months and
symptoms return. The next time hyaluronic acid is injected, it
lasts only about three months. There are no good studies
showing that hyaluronic acid taken orally or in any other form
treats anything. More on hyaluronic acid (Synvisc) injections
