Reservatrol, a compound found in the skin of grapes and other fruit as well as in red wine, seems to have had a lot of press over the last couple of years.
The reason being that high levels of Reservatrol can improve exercise performance due to changes in skelatal muscle and heart function.
A great argument for a post race / training glass of red wine.
Initial studies were carried out on mice and rats. The problem is that any Human trials that have produced any relevent findings have used doses of 1gram of Reservatrol - the equivalent to 667 bottles of red wine.
