As with any study of this nature, there is a good chance that the observed effects won't apply to humans, but it's interesting nonetheless. The researchers point out that there's been a couple observational studies (not RCTs!) that have found decreased mortality in humans that supplement glucosamine: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3557824/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3557824/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2869514/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2869514/ What I'd really like to see, now, is a randomized controlled trial that looks at mortality in healthy, non-arthritic people who supplement glucosamine - alone, without chondroitin or other stuff.
