This is a good product. My daughter bought me some when I visited her in Los Angeles and it was effective, so I purchased more when I ran out.

Works for me! I first bought 3 in 1 in Joint Formula desperation to help with burning and pain in both of my knees caused by torn meniscus several years back. Other Glucosamine and Chondroitin products gave me upset stomach and didn’t seem to work at all. I found this, tried it, and it worked! The combination of ingredients in this 3-in-1 work to completely eliminate the needle sharp pain and dull aching burn in my knees- for months and months! Take the whole bottle. Directions say take 6 caps per day. I would take 2 or 3 at a time, several times a day and not always the full 6 per day.
Relief started for me after about 10-12 days. I don’t know if it will work on every one but it works on me. Read the information in the US Patents and you’ll know why it works so well (niacin, pepper oil, ginger in combination with the other compounds). I have recommended this to friends, and every one of them has found pain relieve after taking the bottle. This was probably my 5th bottle in six years.

There’s alot of snake oil out there…this isn’t one of them. After tripping down some stairs and messing up my knee, I started feeling some small, non-painful-yet-uncomfortable grinding in the kneecap. I took a chance on this, and it worked wonders.
This is not a cure-all, obviously, and a not a replacement for a doctors care…it just helped me heal faster.
