Some time back in the early 90s, it was reported that giving melatonin to lab animals (both mice and rats, I believe) will extend their lifespans by about 25%. Now mice and rats typically live for about 2 or 3 years, which are not especially long lifespans. Has anyone reported any results on experiments with longer-lived animals?
Make of it what you will. Looks like the jury is still out. Nothing conclusive.
Thanks for the links Chao, but none of them reported any experiments on any animal other than mice, at least that I could find. Well, except for the first which was about the effects of melatonin on drosophila melanogaster. However, I doubt that fruit flies live longer than mice.
Anyone else know of any other experiments?
