There is a company working on why resveratrol produces beneficial effects at the sub-cellular level. It's been a while since i read about them so I forget the name but iirc, they were looking at the effects on mitochondrial rna. If they isolate the receptor of the positive effects, then they will run screens for more effective compounds than resveratrol. Once they find one that is safe and works, then we can start thinking about a pill.
Until then: L'Chaim and drink up!
