What is Resveratrol?

Resveratrol - HerbalForMen

Resveratrol is a natural compound called a polyphenol. It belongs to a subclass of polyphenols known as stilbenes.

Resveratrol is produced by plants as a protective mechanism against damage from factors like UV radiation, injury, and fungal infections. This defense property also translates to health benefits when resveratrol is consumed.

The main natural sources of resveratrol are the skin of grapes, blueberries, raspberries, and peanuts. Red wine also contains resveratrol, as it’s derived from grape skin during fermentation.

Resveratrol first gained interest in 1992 when scientists discovered its presence in red wine. Since then, extensive research has confirmed resveratrol’s extremely potent antioxidant, anti-inflammatory, and anti-aging effects.

While whole foods provide small amounts of resveratrol, supplements offer a convenient way to get higher therapeutic doses associated with health improvements in clinical studies.

How Does Resveratrol Work?

Researchers have identified several mechanisms behind resveratrol’s broad effects:

  • Antioxidant - Resveratrol neutralizes free radicals and oxidative stress, preventing cellular damage.
  • Anti-inflammatory - It inhibits inflammatory compounds like NF-kB and cytokines.
  • Vasodilator - Resveratrol relaxes blood vessels by enhancing nitric oxide production.
  • Anti-aging - It activates SIRT1 enzymes linked to longevity and mimics calorie restriction.
  • Estrogen modulator - Resveratrol exhibits selective estrogen receptor modulation for health benefits.

With so many therapeutic targets, resveratrol supplementation can provide system-wide benefits, from heart and brain health to diabetes, longevity, and more.

Key Takeaways on Resveratrol

  • Resveratrol is a polyphenol antioxidant found in grapes, berries, peanuts, and red wine.
  • It offers a diverse range of research-backed health benefits via its antioxidant, anti-inflammatory, vascular, anti-aging, and estrogenic effects.
  • Supplements provide convenient high-dose resveratrol compared to dietary sources alone.
  • Resveratrol is very safe and well-tolerated, with few side effects.

Hopefully this beginner’s guide helps explain what resveratrol is and why it’s grown so popular as a health supplement!
