I'm going to stop taking resveratrol because of cost, bioavailability issues, and lack of research. I'm convinced I would have to take huge amounts to overcome the bioavailability issue (we require 6x the equivalent rat amount). Taking with other polyphenols to enhance the bioavailabilty seems to be a crapshoot. To get the necessary quantity, I would need to switch to a purer extract (even more $$$) to avoid the emodin issue. To top it all off we haven't seen that it extends the lifespan of a rat on a normal diet. The only study showed that it allowed the high fat diet rats to live as long as the normal diet rats.
Instead, I've started doing every third day CR (50% of calories every 3 days).
