S.H.
One thing to keep in mind with these drugs is that they have not been tested long-term in people. Resveratrol was only discovered to work in yeast about 10 years a go. Since it is a "supplement" it doesn't have to show the FDA any long-term studies before going on the market. Another thing to be careful about is that the discoverer of Resveratol has said much of the "reservatrol" on the market was actually made wrong and is not in an active form. I would read up on the drugs first before choosing to take them.
