Will talin this supplement make a noticeable difference?
Well lets put it this way... I've been taking 3000mg of it for a few months now along with vitamin C and have seen no significant improvement save for one week once I started combining it with the C. In my opinion...save your money and try something else.
It will help joints and keep them not as sore as without it but by itself I don't feel as though it would help to improve flexibility (although less sore joints could result in you being able to push your flexibility further)
This is the best case scenario. Expect nothing more.
Isn't that what should be expected? No supplement is going to be a "miracle pill" and suddenly increase flexibility. Dietary supplements are meant to be taken to support your training, not do it for you.
So because it didn't work for you, in your opinion no one should ever take this supplement for joint flexibility ever again? Awesome advice! TS, it'll cost you 40$ max to try it for 3 months. Plus, high amounts of fish oil. Give it a go.
You're a tool. There's many people who have had crap results with glucosamine. Did I say no one should ever try it or take it again? No...what I did was give my OPINION, which last time I checked is allowed here. And in my opinion, there are other things the TS could try before taking glucosamine which by the way requires you to take it for at least 4 weeks before even beginning to see results, which I've never seen. Don't talk to me about crap advice when you push GNC down everyone's throat and tell people to take 10 grams of creatine on workout days and 5 on non-workout days, when all you need is 5 everyday. I'm sure you'd LOVE to see the TS waste $40. As turbozed said, the scientific evidence regarding glucosamine being overly effective is rather poor.
...slowly backing away from crazy person
Crazy or not, at least he's not going to spend money on something that doesn't work.

Turbo, I definitely agree that for any new supplement the burden of proof is to prove it is effective, rather than prove it is not.
That being said, based on all the research I've seen, and while it is obvious it doesn't have spectacular results, I'm not convinced if it's completely ineffective or not. For people with joint issues, considering that articular cartilage damage is a widely non-reversible process (so the chance of a possible aid to slow down it's degeneration is important), suggesting they try it for 3-4 months and decide for themselves is not a bad recommendation.
Evaluation of the effect of glucosamine administration on biomarkers for cartilage and bone metabolism in soccer players. (Oct. 2009)
In the present study, to investigate the effect of glucosamine, a component of glycosaminoglycans with a chondroprotective action, on articular cartilage in athletes, we looked at soccer players, who expose their joints to excessive motion and loading, and compared the levels of biomarkers for type II collagen degradation (CTX-II) and type II collagen synthesis (CPII) between soccer players and non-athlete controls, and in soccer players before and after glucosamine-administration. CTX-II (P<0.01) and CPII (P=0.08) levels were substantially elevated in soccer players compared with those in controls, indicating that cartilage metabolism (type II collagen degradation and synthesis) is increased in soccer players. Of note, glucosamine administration (1.5 g and 3 g/day for 3 months) significantly decreased the CTX-II level (P<0.05); however, the effect disappeared after withdrawal of administration. In contrast, glucosamine administration did not essentially affect the increased level of CPII. Furthermore, cartilage damage was evaluated by using the ratio of type II collagen breakdown to synthesis (CTX-II/CPII). The ratio in soccer players was significantly higher than that in controls (P<0.05), suggesting that type II collagen degradation is relatively enhanced compared with type II collagen synthesis in soccer players than in control students. Of importance, the ratio was reduced by glucosamine administration but returned to the pre-administration level after withdrawal of administration. Together these observations suggest that glucosamine is expected to exert a chondroprotective action in athletes (soccer players) by preventing type II collagen degradation but maintaining type II collagen synthesis, although the effect is transient and disappears after withdrawal of administration.
