I use Alaya Naturals because it has five different kinds of collagen, MSM, glucosamine and chondroitin and sourced with grass-fed, hormone free, cage-free -- all the things I watch for. I started for joint support (I was running half marathons at the time and logging serious miles) but I've kept it up for at least six years at this point, maybe longer. I mix it with my green juice in the morning.

There's lots of brands out there, though, and possibly one more targeting to arthritis. There's some debate as to whether it actually works/does anything, but I find myself able to still do pretty much anything I want athletically at almost 68 and live a pretty pain free life, so I'm happy about that.
