 In the following proposal, the investigators plan to perform a pilot study to evaluate the capacity for ubiquinol reduced form of COQ10 to attenuate mitochondrial injury, to attenuate inflammationvascular endothelial injury, the effect on the human metabolome, and to be absorbed. The overall goal of this line of research will be to determine if CoQ10 will attenuate oxidative injury and improve mitochondrial function leading to overall improved outcome in patients suffering from septic shock. In order to achieve this long-term goal, the investigators propose this pilot and feasibility trial to determine CoQ10 absorption in critical illness, capacity to mitigate inflammatory injury and oxidative injury, and ability to maintain mitochondrial electron transport chain functionality. This pilot study will also provide key feasibility data on blinding and other logistical issues necessary for execution of a larger-scale investigation.
