Resveratrol With or Without Piperine to Enhance Plasma Levels of Resveratrol

There is some evidence that when resveratrol (a substance which is found in red grapes, peanuts and chocolate) is combined with Piperine (a substance found in pepper) it is more effective in fighting cancer. The purpose of this study is to see if resveratrol in combination with piperine is more effective than taking resveratrol alone. Since investigators don't know what dose of piperine to use in combination with resveratrol, two different doses of piperine will be studied. Twenty-four participants, equal numbers of males and females, will receive a single dose of resveratrol (2.5 grams) without piperine, resveratrol (2.5 grams) with piperine (5 mg), or resveratrol (2.5 grams) with piperine (25 mg).
