Resveratrol
Varies
Resveratrol is a polyphenol compound naturally present in red grape skins, berries, peanuts, and Japanese knotweed. It gained widespread attention for its proposed ability to activate sirtuin proteins and mimic caloric restriction, though decades of research and billions in funding have yielded limited convincing evidence of benefit in humans.
