is glucosamine effective by itself?

I was just wondering if glucosamine is effective for joints by itself or does it also need chonditron and msm to be effective?Thanks.

There are more studies on Glucosamine on it's own, although I like MSM.

Take 1500mg Glucosamine for first month and then reduce to 1000mg per day.
