Resveratrol is a natural compound found in certain plants, particularly in the skin of grapes, berries, and peanuts. It is known for its antioxidant properties, which help protect cells from damage caused by free radicals. Many people associate resveratrol with red wine, as it is present in higher concentrations in this beverage. Research suggests that resveratrol may have various health benefits, including potential anti-inflammatory effects and support for heart health. Some studies indicate it could improve insulin sensitivity and promote longevity, although more research is needed to fully understand its effects on human health.
