Yes: They don`t conflict but there is not much evidence for their doing any good.

Different forms: Glucosamine is a supplement currently used for joint health. It comes in various forms, two of which you have listed. The difference is simply the side-groups on the glucosamine molecule (sulfate vs n-acetyl group). The one most studied is glucosamine sulfate. Studies suggest that it shows promise for osteoarthritis but the jury is still out.

Unknown: All meds & supplements have potential side effects, and usually it's a pretty long list of potential but uncommon side effects. Side effects are not always dose dependent, so even 1 dose can sometimes cause. Just b/c it's a supplement doesn't mean no risk. I discuss w/ my pts about doing a risk-benefit analysis before starting a new tx.

What role will glucosamine play in osteoarthritis?

Dr. PHILIP WALLER

Unsure: People have tried glucosamine and believe they have less pain from osteoarthritis. However there are many peole who have taken it without any benefits. A study from the nih looked at glucosamine and was not able to find a direct benefit from glucosamine. In my practice, I have suggested it with chondrotin for oa and occassionaly see some relief in knee and hip pain. It does not reverse or cure oa.
