Purpose
The purposes of this study are two-fold. The first purpose is to determine the effect of taking vitamins on the recovery of an artery (blood vessel) following an induced temporary injury. The second purpose is to determine whether a specific vasodilator is less abundant after the injury and whether this contributes to increased constriction or after the injury. Finally, does vitamin consumption have an effect on the recovery from the injury if one of the substances in the blood that causes vessels to enlarge (dilate) is stopped?

Primary Outcome Measures:
- Change in flow mediated dilation [ Time Frame: Change from baseline at 15 minutes after ischemia-reperfusion injury ] [ Designated as safety issue: No ]Flow mediated dilation is a measure of vascular function and is measured as the outcome before and after an injury to the inner lining of the artery.
Secondary Outcome Measures:
- Change in low flow mediated constriction [ Time Frame: Change from baseline at 15 minutes after ischemia-reperfusion injury ] [ Designated as safety issue: No ]low flow mediated constriction is a measure of vascular function and is measured to establish the impact of a vascular injury
