Joint supplement worth the expense?

[robB]

I have dealt with chronic patellar tendoin issues for over 15 years now. I have for several years, used joint supplements with the idea that the supplement will help keep the joint healthy. My thought is that my knees always hurt, so hopefully the supplement is preventing other potential joint soreness.

I'm not really sure if the supplement is worth the expense or not. I am curious to hear your professional opinion. For reference, I am using a supplement that includes:

• Glucosamine 1500 mg., Chondroitin 800 mg., MSM 750 mg. per Serving

It is not worth it, in my opinion, as there is no good data to suggest it works better than placebo.
