The benefits of reversatrol were refuted a few years ago. In fact, it has a few negatives. This study is specific to anesthesia based issues
Many questions WRT to the refutational studies as well. Dosage, timing, oxidized/non-oxidized state of the resv. used, co-factors, the agenda of those conducting the studies, etc. Similar in many ways to questions about the studies refuting the benefits of Vitamin D.
PS Unlike the Vitamin D studies, one of the criticisms of the resveratrol studies was the use of too high a dose.
