I'm so glad I found this product. Not only does it have a high level of Hyaluronic Acid, which I was looking for, but it also has a high level of some of the best Collagen II I've found. I like the fact that I have instant relief from the pain in my back, knees and muscles, as well as smoother skin and less wrinkles . This is my second bottle and I will continue using it since it has the perfect combination of two products I had been looking for before coming across this all in one formula. I also take it with Vitamin C to help the collagen assimilate into the bloodstream.
