Roll Call does not check drug interactions or assess personal safety.
A dried extract or powder made from red wine or red grape skins, used as a source of polyphenols such as resveratrol, anthocyanins, and other flavonoids.
Why it’s used
Taken by some for general antioxidant support, echoing the reputation of red wine polyphenols in cardiovascular research.
What the evidence says
Much of the public interest in red wine traces to epidemiological associations between moderate wine consumption and cardiovascular outcomes, and to laboratory research on resveratrol, one of its many compounds. Isolated resveratrol has its own clinical literature with mixed human results at studied doses. "Red wine extract" as a standalone supplement ingredient — as opposed to whole wine consumption or isolated resveratrol — has not been established in oral-supplement trials.

"Red Wine"[Title/Abstract]
This says what this database holds under these terms. It is not a finding that no research exists.
Context
Evidence appears to exist for whole-wine epidemiology and for isolated resveratrol, but not for dried red wine extract itself as a supplement ingredient. A reviewer would look for trials using standardized resveratrol content or whole-wine consumption studies, not this generic extract.
