How much does Glucosamine help? Week 1

I am hoping that the rumors I have heard are true for this one. I am taking Glucosamine daily at the recommended dosage to see what effect if any it has on my knees. So far after a week I haven't noticed anything (nor did I expect to).

I am starting outdoor soccer again in a few weeks and as soon as the water warms up a bit I will be out wakeboarding again. Those will be the real tests in my opinion.
