The widely used food supplement glucosamine promotes longevity in aging mice by approximately 10 percent due to improved glucose metabolism. Researchers find that the compound does so ‘by mimicking a low-carb diet in elderly mice reflecting human retirees.’ In addition, the results of the study seemed to give some indication of protection from diabetes, a life-threatening disease most prevalent amongst the elderly.

    @danpsdsu.patrick what would you recommend as the daily amount for glucosamine for those interested in longevity?

      Don’t know! Rhonda (@rhonda) gave the specifics of the study in a comment below – basically, to do what they did, you’d have to be eating like a a pound and a half to a couple of pounds of glucosamine every day. Not very practical in any case. But hey, maybe start a little lower and it can’t hurt, right?

      Is there a daily amount you would suggest one should consume to have an affect on life span?

        @KickAssBrockSamson In this study they fed mice very high doses of glucosamine, 4.5g per pound of body weight. This is impossible for humans to consume! Interestingly, the mechanism of lifespan extension appears to be a metabolic switch towards increased protein metabolism. Also, glucosamine inhibits cancer cell metabolism.

          That would be ¾ a kilogram per day for me… that’s nuts. I’d love to know how they even got the mice to eat those sorts of proportions.
