Resveratrol is a naturally occurring polyphenol compound found in various plants, particularly in the skins of red grapes, berries, and Japanese knotweed. This powerful antioxidant has gained significant attention in recent years for its potential health benefits, particularly in the areas of anti-aging, cardiovascular health, and longevity.
First identified in the 1940s and popularized by the 'French Paradox' observation in the 1990s, resveratrol has become one of the most extensively studied natural compounds in nutritional science.
Resveratrol belongs to a group of compounds called stilbenes, which plants produce as a defense mechanism against environmental stress, infection, and UV radiation. In the human body, resveratrol acts as a powerful antioxidant, neutralizing harmful free radicals that can damage cells and accelerate aging.
The compound exists in two forms: cis-resveratrol and trans-resveratrol. Trans-resveratrol is the biologically active form that provides health benefits, which is why quality supplements specify their trans-resveratrol content.
While resveratrol is found in various foods, the highest concentrations come from:
However, obtaining therapeutic doses from food alone is challenging, which is why many people turn to concentrated supplements.
Research suggests resveratrol may offer numerous health benefits:

Sirtuin Activation: Resveratrol activates sirtuins (particularly SIRT1), proteins that regulate cellular health, metabolism, and aging. This activation mimics some effects of caloric restriction, a well-established longevity intervention.
Antioxidant Activity: It neutralizes reactive oxygen species (ROS) that cause cellular damage and contribute to aging and disease.
Anti-Inflammatory Action: Resveratrol inhibits pro-inflammatory enzymes and signaling pathways, reducing chronic inflammation.
Mitochondrial Support: It enhances mitochondrial function and promotes the creation of new mitochondria, supporting cellular energy production.
Clinical studies have used resveratrol doses ranging from 150mg to 2000mg daily, though most research focuses on the 250-500mg range. For general health maintenance, 200-400mg of trans-resveratrol per day is typically recommended.

Resveratrol is generally considered safe with few side effects when taken at recommended doses. Some people may experience mild digestive discomfort, nausea, or diarrhea, particularly at higher doses.
Important Considerations:
Always consult with a healthcare professional before starting any new supplement regimen, especially if you have existing health conditions or take medications. Check our FAQ page for more information.
