Resveratrol is a polyphenol—a type of plant-based antioxidant—found in many foods, not just red wine. It is produced by plants to fight fungal infection, stress, and UV radiation. [1]
Top Food Sources of Resveratrol (Besides Red Wine)
• Berries: Blueberries, cranberries, bilberries, and mulberries are significant sources.
• Red Grapes and Juice: The skin of red and purple grapes holds high concentrations (50-100 micrograms per gram).
• Peanuts & Peanut Butter: Peanuts, particularly boiled, provide a good source.
• Pistachios: These nuts are a rich source of resveratrol.
• Dark Chocolate & Cocoa: High-cocoa content products contain small amounts.
• Japanese Knotweed: This plant is often used in natural supplements due to its very high resveratrol concentration. [2, 3, 4, 5, 6]
Key Facts on Resveratrol
• Trans-Resveratrol: This is the most studied, biologically active form, available in many supplements.
• Skin/Roots: It is primarily found in the skin of fruits and the roots of plants.
• Alternatives to Alcohol: Consuming whole fruits like grapes or berries is recommended to get resveratrol without alcohol.
• Health Focus: It is researched for antioxidant, anti-inflammatory, and cardiovascular benefits. [2, 6, 7, 8, 9]
