BioCell Collagen II has been on the market since 1997 and has been effectively used by millions of people since then. Even though research exists on hydrolyzed collagen, BioCell Technology has initiated two double blind placebo controlled studies to confirm the proven effects of this ingredient. In the village of Yuzurihara, Japan (also known as �village of long life�), there seems to exist a population that has the longest age span in the world. Featured on ABC television, this village had one common thread�maintenance of hyaluronic acid (HA) levels in their bodies. The people of this village were living to old ages without wrinkles and common age-related diseases. In fact, Bill Sardi, author of the new book, HA: How to Live 100 Years without Growing Old (available from Here and Now books), discusses this very phenomenon. HA and collagen have been studied by scientists for over 40 years. It is a key component to many normal bodily functions and has hundreds of research studies showing its value in skin and joint health.</p>
