Does beetroot juice supplementation improve exercise capacity and cardiovascular parameters in patients with chronic obstructive pulmonary disease (COPD)?
Beetroot / Dietary Nitrate, a systematic review and meta-analysis (Nutrition Reviews 2026, PMID 41996285) — BJ also reduced systolic blood pressure by 5.33 mmHg and diastolic blood pressure by 3.01 mmHg. The abstract for Beetroot / Dietary Nitrate states no limitations.

Beetroot juice supplementation can improve exercise capacity and lower blood pressure in individuals with COPD.
The question
Does beetroot juice supplementation improve exercise capacity and cardiovascular parameters in patients with chronic obstructive pulmonary disease (COPD)?
What they tested
Beetroot juice supplementation will improve exercise capacity and cardiovascular parameters in COPD patients, with potential differences in effects based on study design (parallel vs. crossover trials).
How they did it
A systematic review and meta-analysis was conducted by searching Scopus, Lilacs, PubMed, Embase, Web of Science, CENTRAL, and Science Direct databases up to December 30, 2024. Two independent reviewers extracted data on participant characteristics, supplementation protocols, exercise capacity, and cardiovascular parameters from studies on nitrate-rich beetroot juice in COPD patients. Data synthesis involved subgroup and sensitivity analyses, meta-regression, and stratified random effects meta-analyses. Risk of bias was assessed using RoB2, and evidence certainty with GRADE methodology.
What they found
Twelve studies involving 357 participants were included. Beetroot juice significantly improved exercise capacity (standardized mean difference [SMD], 0.31). Stratified analysis showed greater benefits in parallel RCTs (SMD, 0.52) compared to crossover trials (SMD, 0.06). BJ also reduced systolic blood pressure by 5.33 mmHg and diastolic blood pressure by 3.01 mmHg.
| Overall | 0.31 | |
|---|---|---|
| Parallel RCTs | 0.52 | |
| Crossover Trials | 0.06 |
Standardized mean difference (SMD) in exercise capacity with beetroot juice supplementation, showing overall effect and effects stratified by study design.
What it means
This meta-analysis provides strong evidence that beetroot juice improves exercise capacity and key cardiovascular parameters in COPD patients. Stratifying results by study design addressed previous methodological limitations, establishing a reliable foundation for clinical application.
Limitations
The abstract does not explicitly state limitations of the current meta-analysis, but it does suggest the need for standardized long-term studies to confirm findings and elucidate dose-response relationships.
Where the published abstract does not list limitations, we say so rather than inventing them. Read the full paper on PubMed before drawing conclusions.

Beetroot / Dietary Nitrate
Meta-analyses of randomized trials show that beetroot juice and dietary nitrate lower blood pressure—about 5 mmHg systolic on average across trials in hypertension, and in one pivotal placebo-controlled trial in hypertensive patients roughly 7-8 mmHg, including 24-hour ambulatory readings, sustained over four weeks…
