Vitamin C did not affect plasma FFA concentrations. Glyceryl trinitrate responsiveness was unchanged during FFA elevation, with or without vitamin C. These data suggest that FFA-induced vascular oxidative stress could contribute to endothelial dysfunction in insulin-resistant patients. High concentrations of antioxidants are able to reverse the local effects of FFA on endothelium-dependent vasodilation.
