I can tell if I forget to take it.

I don't believe the hype that this product brings about miraculous movement and makes people pain free - I wonder if "plants" wrote those reviews. I do, however, think joint support is a necessary supplement and it's important for me as a 40+ person. Rarely do I see, in one pill, all three known ingredients for joint support: Glucosamine, MSM and chondroitin. That is why I like this product. A forth ingredient that brings about results is shark cartilage (which would be a nice addition although not good for the shark population!). So if this doesn't work for you consider taking that. The only drawback for Triflex is that you must take it it 3X a day. I take it once or twice a day but would probably enjoy more flexibility, etc. if I used it as recommended. I do trust the GNC Brand.

When I purchased TriFlex, I immediately thought it wouldn't work. I decided to take it anyway for my knees. To my surprise, after about a week, the pain in my knees and back were so slight. I've tried almost everything to lessen the pain in my knees and back and nothing worked. I was so amazed, that this product worked for my back as well as my knees. I give TriFlex five (5) stars. I feel like I can run a marathon.

I used to have neck and back pain constantly and went to the chiropractor every 6 weeks. I work out at the gym 5 days a week and am in my late 40's. Since I have started taking Triflex - my pain is less and makes it so I do not have to see my chiropractor.

This product is amazing! I sustained an injury to my hand and the pain plagued me for months. It appeared to activate an early onset of arthritis in my hand, and no over the counter anti-inflammatory or pain medication seemed to help over the course of 6 months. Having heard wonders about Glucosamine/Chondroitin compounds, I thought I'd give this product a try before seeking medical attention. Within 4 days of taking three Triflex, my pain disappeared. I continued to take 3 per day for a month, after which I tapered down to one pill a day. Since that time, I have tried going completely off the Triflex, but the pain returns within a few days. This stuff does wonders and is much preferable to taking narcotic or anti-inflammatory medications.
