Adequan works. My mare's knees used to pop and she used to get sore, a few months of Adequan, she is great! I would talk to your vet, and have him do flexx tests and see if your horse needs it's hocks injected and then if your horse needs a joint supplement, then they will give you the right one.
There is debate whether oral joint supplements can work but the problem is Scientifically, many potentially promising benefits of oral supplements exist, but to date the efficacy of oral joint supplementsin horses is unproven. There is also debate of whether Chondroitin can work due to the molecular weight. Personally I'm not a big fan of Adequan either but it is a good product depending on your needs. The expense to me is not worth the often unclear benefits, if injections are needed they are administered to my horses and though the cost is expensive the benefits are there. That is just a personal opinion of mine in weighing cost and potential benefits.
I'm a big fan of feeding Omega3 products for joint inflammation as well as the multiple other benefits that are scientifically documented. It will not repair the cartilage as is the goal on oral joint supplements but as I stated above. I know you asked for an oral joint supplement but if I had to choose I would feed and omega3 product like Eo-3. That said I actually feed both but Eo3 and KERFlex but mostly because I get the oral joint supplement at cost because my wife works there. EO•3 a KERx Solution
Here's an article on omega3 and joint inflammation that was in equine review. http://www.ker.com/library/EquineRev...rition/N27.pdf
Btw, there is research currently being conducted on whether certain engineered HAs taken orally work on a molecular level much in the same way as Adequan does IM. It has not been completed yet but at least we are starting to see more research in the area but it is extremely hard to prove of disprove whether oral joint supplements actually work and to what level.
