Effect of dietary inorganic nitrate (nitrate) supplementation on vascular function in study 1. Vascular function was assessed by alterations in leg vascular conductance (LVC) in response to passive leg movement (A) and by brachial artery flow-mediated dilation (FMD; B) for both placebo and nitrate conditions in patients with hypertension taking antihypertensive medications. Individual (circles) and mean (bar) data are reported; n = 13 for all variables. LVC, leg vascular conductance.
