What dosage is best for glucosamine chondroitin and can anyone tell me a little more about them?

I suffer with early arthritis in various joints but my major problem is discular degeneration in my lower back causing referred pain and inflexibility due to muscular spasm.

I have read lots of information on the benefits of glucosamine, and chondroitin.

What dosage should I take of these supplements as a chronic sufferer, (as against someone who doesn't have the problems I have yet)?

I have seen suppliers advertising various strengths of these supplements ranging from 100 to 1500mg.

How much of the maximum dosage can the body take before it passes the remainder as waste, (as in Vitamin C)?

Is there any advantage to taking the maximum dose?

Can anyone recommend a supplier, that is inexpensive - these supplements seem to be quite expensive if you go to the high street, (i.e. Holland & Barrett).

Here is a suggestion. Have you tried WEB MD yet for any information?? I use glucosamine once in a while for knee/joint pain but I have no knowledge on the milligrams other than the web site I suggested. Go look, maybe it will help?
