I never leave reviews, but i just have to for this product. Five years ago i sustained a debilitating neck injury that left me with a pinched nerve, severe unrelenting Dizziness and chronic fatigue and pain. Some days I would be sitting around doing nothing and my neck and back would burn like i was on fire. I've been to a half dozen doctors and all they did was give me NSAIDS and antidepressants. X-rays showed i had cervical arthritis. The odd thing was I couldn't sleep for over six or seven hours otherwise i would be so dizzy and fatigued the next day i couldn't function. This has gone on for over five years now. I've spent tens of thousands of dollars on doctors, medicine and supplements to no avail. The doctors said I just had to learn to live with it. Then, about two months ago, I came across an article online about arthritis which said Type ii collagen could reverse osteoarthritis. I didn't get my hope up but bought some anyway. One week later the pain stopped and hasn't returned. Then I noticed something awesome...I started sleeping over eight hours a night and feeling great the next day. No Dizziness or fatigue. This is the first time in five years I've had any relief! If you're suffering from arthritis buy some asap, you won't regret it. UC-II Collagen is a miracle drug not just a supplement! P.S. In addition to this product I've also bought some hyaluronic acid after watching a video on youtube called "Hyaluronic Acid: The Fountain of Youth" by ABC News. If you haven't watched the video, check it out. David Salem, Orego
