Resveratrol

What This Supplement Is

Resveratrol is a natural compound classified as a stilbenoid, which is a type of polyphenol. It is primarily found in the skin of grapes, as well as in blueberries, raspberries, mulberries, and peanuts.

This compound is produced by plants in response to stress, injury, or pathogen attack, acting as a protective agent. Resveratrol has garnered attention for its potential health benefits, particularly in the context of longevity and general wellness.

How It Works in the Body

Resveratrol is thought to exert its effects through several mechanisms. It acts as an antioxidant, helping to neutralize free radicals that can cause cellular damage.
