What do u take for joint health?

I am wondering what u all take for joint health? 

I am just back to the gym after dx arthritis in knee n would like some advice.

I have taken glucosamine after my RNY, mostly i swim and do non weight bearing exercise like the  stationary bike...there is always heat or ice.........

Im looking forward to see the replies on this, Im 32 yrs young and already need knee replacement surgery and the injections didnt help them but for maybe a month. Im trying to put off my knee surgeries to get some of this weight off and hopefully it will help but in the meantime i need something to help the arthritis in my knees, hips and back.
