Resveratrol is a bioactive molecule found in plant sources such as grapes, peanuts, blueberries, and, famously, red wine. Resveratrol has anti-inflammatory and antioxidant properties that benefit cardiovascular function, glycemic control, and lipid metabolism. Although it’s promoted for lifespan extension, there’s no evidence for this in humans and limited evidence in animals.

Resveratrol is a plant compound found in grapes, peanuts, and blueberries and is notably present in red wine. It was previously associated with the "French Paradox," which suggests that red wine consumption may contribute to the low incidence of cardiovascular disease in the French population despite a high-fat diet. However, current research challenges this direct link.
Resveratrol is primarily recognized for its potential cardiovascular health benefits. These include improvements in endothelial function and possible blood-pressure-lowering effects. It also shows positive effects on fasting glucose, HbA1c, and insulin sensitivity in adults with type 2 diabetes and consistently reduces inflammatory cytokines. However, research indicates that it does not improve blood lipids in nonalcoholic fatty liver disease or improve body composition in cardiometabolic conditions.
Resveratrol has poor bioavailability due to rapid metabolism and may cause intestinal upset and nausea at high doses. Additionally, doses of 1,000 mg per day or more can interfere with the metabolism of various medications, so consulting a doctor before supplementation is advised.
Resveratrol works by protecting cells from oxidative damage, increasing antioxidant levels, and inhibiting proinflammatory cytokines, which contribute to its cardioprotective effects. Additionally, it activates metabolic regulators to improve lipid metabolism and insulin sensitivity, which potentially aids in the treatment of conditions like nonalcoholic fatty liver disease and type 2 diabetes.

Large FAQ and database update
We modified the FAQs on reseratrol's main drawbacks, how resveratrol works, and added FAQs about longevity and red wine. Additionally we added about 60 new studies to the database. The take-home messages remain largely consistent with what we previously knew about this topic.
