The list of perks from drinking red wine seems to get longer and longer.

First, we heard large amounts of the red wine component called Reservatrol helped obese lab mice live longer.

Now, researchers in France say Reservatrol boosts the animals' endurance too.

Mice treated with the substance could run twice as far as they normally would.

Before you take a bottle of Merlot to your next marathon, keep in mind that scientists do not know what effects large doses of red wine could have on humans.

The mice in the study took in amounts of Reservatrol that would be unsafe for people.
