Systolic blood pressure less than 160mm Hg and diastolic blood pressure less than 100 mm Hg (defined as Hypertension stage 2). * Be willing to avoid consuming dietary supplements, prebiotics, probiotics, or fibre-rich supplements within four weeks prior to the baseline visit, and until the end of the study. * Be willing to avoid physical exercise for the duration of the study (physical exercise defined as any physical activity that is planned to achieve a fitness goal) * Be willing to consume the investigational products daily for the duration of the study. Exclusion Criteria: * Pregnant, lactating, menopausal or post-menopausal women, or women who are planning to become pregnant over the study period. * Have had antibiotic treatment within three months prior to baseline. * Are taking a medication that the investigator believes would interfere with the objectives of the study, pose a safety risk, or confound the interpretation of study results; to include: anti-inflammatory drugs, H2 blockers, antacid, proton pump inhibitors, anti-hypertensive medications, corticosteroids, laxatives, enemas, antibiotics, anti-coagulants, immunosuppressant medication. Participants should have a wash-out period of at least two-weeks for each of these medications except for antibiotics, which should not have been taken in the previous three months.
