Effect of Inorganic Nitrate Supplement on Blood Pressure

Acute and Sustained Effects of Plant- Based Bio-Equivalent Nitrate Supplement Tablets on Blood Pressure Reduction, Nitric Oxide Mediated Endothelial Function and Saliva Bioconversion of Dietary Nitrate in Hypertensive Men and Women

The primary purpose of this project is to assess the efficacy (effectiveness) of plant-based nitrate tablets to elevate nitric oxide in your system as measured by saliva and effect on lowering blood pressure (BP), supporting blood vessel function in men and women with hypertension.

Study Overview

• Status: Completed
• Conditions: Blood Pressure; Endothelial Dysfunction
• Intervention / Treatment: Dietary supplement: Placebo; Dietary supplement: Plant based bioequivalent Nitrate supplementation

Detailed Description

This clinical trial is to assess the efficacy of plant-based bioequivalent Nitric Oxide supplement for improving blood pressure and endothelial reactivity over a 12 weeks intervention period in individuals with metabolic syndrome. The study also examines the effect of plant-based bioequivalent Nitric Oxide supplement on other markers of cardiovascular function and cardiovascular disease risk including Total, LDL and HDL-Cholesterol, Triglycerides, and a multitude of inflammatory markers.
