Abstract

Objective: To evaluate whether consumption of nitrate-rich beetroot juice, compared to a non-nitrate enhanced diet, affects blood pressure (BP) in adults with hypertension.

Methods: A systematic literature search was conducted using Google Scholar, Cochrane, EBSCOhost/CINAHL, and PubMed. Search terms included "beetroot juice," "blood pressure," and "hypertension." Inclusion criteria: studies published since 2019, in English, full-text, involving human adults (≥ 18 years) with hypertension, examining the effects of nitrate-rich beetroot juice (70-250 mL daily) compared to nitrate-depleted juice or no intervention, and reporting both pre- and post-intervention BP. Exclusion criteria: studies published before 2019, not in English, not in full text, involving animals/children/adolescents, involving normotensive healthy adults, participants with secondary hypertension, pregnant patients, those administered beetroot in other forms, using juice quantities outside the 70-250 mL range, and without systolic blood pressure (SBP) and diastolic blood pressure (DBP) outcomes.

Results: Three of the five selected studies demonstrated statistically and clinically significant reductions in clinic-measured SBP following nitrate-rich beetroot juice consumption. One study showed a significant reduction in 24-hour ambulatory SBP, while two found little to no effect. Across all studies, DBP changes were inconsistent, regardless of measurement method.

Conclusion: Among adults with hypertension, daily intake of nitrate-rich beetroot juice is associated with reductions in clinic-measured SBP. However, effects on 24-hour ambulatory SBP and both clinic and ambulatory DBP are inconsistent. These findings suggest greater reliability in lowering clinic SBP, but warrant further investigation using standardized protocols and longer follow-up periods.

Keywords: hypertension, beetroot juice, nitrate, blood pressure, systolic.

Biographical Information about Author(s)

Angelina Neme is an anticipated graduate from the Valparaiso University Physician Assistant Program. Angelina was inspired to research the topic of “Effect of Nitrate Rich Beetroot Juice on Blood Pressure in Hypertensive Adults” because she has a special interest in the use of nutraceuticals and non-pharmacological ways to manage chronic conditions.
