Dr. Matt Ranks Longevity Supplements: The Winners and Total Scams
Comment
Resveratrol has shown strong rejuvenation effects directly in human cells in vitro turning old human cells into young cells, it has extended the lifespan of over half a dozen species, and even in primates it extended lifespan by over 20% albeit too few primates to reach statistical significance. Reason it failed in rodents, is due to fast liver clearance, in fish with slow clearance over 50% extension is seen. New formulations might address this issue.
