Effect of Inorganic Nitrate Supplement on Blood Pressure

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.
