Just switched about 2 weeks ago from another amazon brand to this joint defense formula. 2 caps per serving, 30 servings per bottle. Premium price, but you get premium ingredients that are formulated in the US. They seem to be doing their stated job well. No side effects or aftertaste with this product. Happy with results. For Reference: 42 year old male no health issues.
I'm a 64 year old woman with multiple health issues. I used to wake up every morning in pain. My back, shoulder, neck and hands. (For some odd reason I end up sleeping on one or both of my hands). Once I started taking these, I wake up with little or no pain. So refreshing. Higher price, but worth it for the results.

I have a few age related joint issues, one with my knees (I’m an avid hiker,) also some shoulder issues. This formula has just bout everything I know of to be effective: glucasomine, chondroitin, boswella, Vitamin C, D3 and magnesium, Ashwaganda, Bromelain, yucca root, Evening Primrose oil, tumeric and Green lipped mussel and hyaluronic acid. I used to work in a health food store and I can say from experience that many of these things have been around for decades, usually sold separately or in smaller combos (like glucasimine and chondroitin.) Most have some serious science behind them in terms of the way they can reduce inflammation in the body and/or promote joint health. I think this is one of the best all round formulas for joint health. Highly recommended.
