Inorganic Nitrate Supplementation on Cerebrovascular Aging and Arterial Stiffness Study

Reduced nitric oxide bioavailability with aging contributes in part to increased large central artery stiffness and cerebrovascular dysfunction. Large central artery stiffness is a risk factor for cognitive decline mediated in part by the development of cerebrovascular dysfunction. This study will investigate the degree to which improving nitric oxide bioavailability using dietary inorganic nitrate supplementation improves cerebrovascular function through reductions in large central artery stiffness in middle-aged and older adults.
