Inclusion Criteria: * Male or female of 18-75 years of age * If female, subject is not of child bearing potential * Subjects with seated resting systolic blood pressures between 130-160 mmHg and diastolic between 85-100 mmHg (inclusive) at screening visit * Subjects with mild to moderate endothelial dysfunction * Agreement to maintain current level of physical activity and diet throughout the study * Agrees to comply with study procedures including abstain from coffee at least 14 hours before blood pressure measurement and abstain from physical exercise at least 4 hours before blood pressure measurement * Has given voluntary, written, and informed consent to participate in the study Exclusion Criteria: * Females who are pregnant, breastfeeding, or planning to become pregnant during the course of the study * Seated office systolic blood pressure outside of the target range (systolic blood pressure \<130 mmHg or \>160 mmHg) or diastolic blood pressure \<85 or \>100 mmHg at screening * The use of natural health products for the treatment of hypertension within 2 weeks of screening * Significant cardiac history defined as a history of myocardial infarction (MI); coronary angioplasty or bypass graft(s); Valvular disease or repair; unstable angina pectoris; transient ischemic attack (TIA); cerebrovascular accidents (CVA); congestive heart failure; or coronary artery disease (CAD) * Type I diabetes * Unstable medical conditions that in the opinion of the Principle Investigator preclude the subject from participating in the study * Alcohol or drug abuse within the last 6 months * Participation in a clinical research trial within 30 days prior to randomization * Individuals who are cognitively impaired and/or who are unable to give informed consent * Any other condition which in the Investigator's opinion may adversely affect the subject's ability to complete the study or its measures or which may pose significant risk to the subject
