Effect of High Nitrate Vegetable Juice Supplementation on Plasma Nitrate and Blood Pressure in Healthy Adults

Aims: The aim of this study is to carry out a randomised crossover intervention study examining the effect of two different high nitrate vegetable juices on plasma nitrate levels and blood pressure (BP) in healthy adults. Objectives: 1) to conduct a pilot cross-over randomized intervention study testing the hypothesis that the health benefits of two different high nitrate vegetable juices products will be similar; 2) to measure the volunteers\' BP as the primary outcome; and 3) to collect biological samples over the course of this study for the measurement of proposed biomarkers of nutritional status, including plasma nitrate.
