i use NutraJoint by Knox. it has 1500 mg of Glucosamine, 1200 mg chondroiten, 500 mg MSM, and 2000 mg of gelatin in it per 4 caps (daily serving). gelatin is really underrate, but extremely benifical for joint health.
one of my friends is really into rock climing, and was having problems with his wrists and fingers. he started eating about a bag of GummyBears a day, and the problems went away. i think supplementing might be better though, cause you don't get all the sugar..
