Early quercetin research on heart and vessel disease is mixed. Some study results are positive but some are open to debate. For example, researchers link eating lots of foods high in quercetin to a lower risk of heart-related death in older men. But other studies are less convincing.
Resveratrol and quercetin have a few things in common. They’re both plant compounds, called flavonoids, and they both have specific effects on biochemical and metabolic functions in certain cells. For instance, both have been shown to inhibit cell proliferation (growth in numbers) and to induce apoptosis (programmed cell death) in cancer cells. Those are impressive talents.
