How does red wine affect the thickness of blood?

Red wine contains compounds like resveratrol and flavonoids, which may have a mild anticoagulant effect, potentially reducing blood viscosity. Moderate consumption of red wine has been linked to improved cardiovascular health, as it may help prevent the formation of blood clots. However, excessive consumption can lead to adverse effects, including increased blood pressure and other health risks. Overall, moderation is key to any potential benefits related to blood thickness.
