What should I say ..... it's glucosamine :) Packaging is good, capsules have to swallow a decent size and tasteless. On the question whether the stuff works, I can not make a qualified statement because I'm not an expert for this. But for me, it helps. I have begun to decrease my low back pain due to work (sitting for long periods) and training loads and that works for me. It is certainly not a panacea, but it was worth a try. Add to this the price of course is a hit compared to products from the pharmacy [to whom I could not tell the difference].
