I was diagnosed with severe joint deterioration in my spine a few years back and have tried virtually EVERY single joint/ligament/cartilage supplement under the sun. This is the first time I have heard of this particular product, but indeed, it doesn't look too shabby in my humble opinion. The ingredient of highest importance in this blend is the CMO (cetyl-myristiolate), and it looks like it has a fair amount in the blend. CMO is one of the only things I have found to help with severe arthritis, from experience, I know it is an absolutely amazing supplements for rebuilding damaged/destroyed joints and also in the maintenence of healthy joints. It is very potent, and thus quite expensive; but it is well worth every penny. The other ingredients in this blend are plenty effective in the art of joint maintenence...particulary Collagen type II and Bromelain. MSM and chondroitin are both staples in any solid joint formula. The devil's claw and boswellia are both nice additions as well, speaking from my own personal experience. I am unfamiliar with the benefits of Yucca. On paper this appears to be an above average supplement for joint maintenence/repair, however without having taken it I cannot speak on the actual effectiveness of this product. But to answer the original question, in my opinion, yes this looks like a good product no doubt.
