Scientists have hypothesized that resveratrol may be a key component of the famous “French Paradox”, whereby the French traditionally were protected against heart disease despite a diet high in butter and animal fats. Resveratrol is a phytoalexin, a natural plant antibiotic which is produced by vitis vinifera as a response to attack by molds. Because of the wide-spread use of pesticides in modern wine-making, including the practice of copper sulphation, the level of resveratrol in modern wines has plummeted. Red wine contains resveratrol, but the quantity varies depending on where the grapes are grown, the time of harvest, and other factors. In fact, usually only 1-3 mg resveratrol per liter of red wine is currently found, even in the most robust red wines. After years of relentless research, a standardized resveratrol extract is now available as a dietary supplement.

This whole grape extract contains a spectrum of polyphenols that are naturally contained in red wine such as proanthocyanidins, anthocyanins, flavonoids, etc.

Based on studies that higher amounts of resveratrol may be beneficial, Life Extension offers a 100 mg standalone product.
