Mongoose- about 6 years ago I was introduced to "DONA" Crystalline Glucosamine Sulfate. It is patented by ROTTAPHARM and is a prescription drug in Europe.
It has been available over the counter in US and Canada for 10 or so year.
I did research on it and there had been two separate blinded controlled studies done on it, both of which I read. One amazing take away from both of the studies was that at the end of the two (as I recall) year studies, those taking DONA had an increase in the distance between the femur and tibia indicating an increase the cartilage while the control group had a decrease. This has been attributed to the patented ingredient as I understand.
I believe you can get the links to the studies from WynnPharm the master distributor for North America. Google

On a related note I also remember reading ratings of Glucosamine products by either Comsumer's Report or Consumer Research that showed the various amount of Glcosamine in various brands, one brand had ZERO Glucosamine in it.
About a year ago the price virtually doubled (shades of Shkreli) so I tried another brand for about six months and noticed a difference. Subsequently the price has come back down some and I have gotten back on the DONA and have noticed quite an improvement.
