Resveratrol Activates Sirtuins to Switch on Energy Producing Mitochondria




A new study, just published in the prestigious journal Science, appears to substantially vindicate the recently beleaguered resveratrol longevity research of David Sinclair:


. . . a new study led by David Sinclair of the Harvard Medical School, who in 2003 was a discoverer resveratrol's role in activating sirtuins, found that resveratrol did indeed influence sirtuin directly, though in a more complicated way than previously thought.    . . .    . . . activated, the sirtuins do several things, one of which is to switch on a second protein that spurs production of the mitochondria, which provide the cell's energy. This would explain why mice treated with resveratrol ran twice as far on a treadmill before collapsing from exhaustion as untreated mice.
