What the rows share
From the rowsThe best-graded row, grade B, is a meta-analysis of 1,823 people (2025) and found an improvement.
The rows run from 68 to 1,823 people, published from 2013 to 2025: 4 pooled reviews and 1 single study.
The rows
4 improved · 1 mixed- BGrade BBlood pressure and arterial stiffness (dose-response) · Improved
Meta-analysis, 75 studies · n 1,823 · 2025 · 75 RCTs of dietary nitrate in adults with and without health conditions
Analysed per 1 mmol (62 mg) of nitrate · Acute to medium term
Each extra mmol of nitrate lowered systolic pressure by 0.28 mmHg acutely, 0.24 mmHg short term and 0.48 mmHg medium term, and diastolic pressure by 0.12 mmHg. Medium-term pulse wave velocity, flow-mediated dilation and augmentation index also improved in a linear dose-response.
- CGrade CClinic blood pressure in hypertension · Improved
Meta-analysis, 11 studies · n 349 · 2024 · Adults with hypertension (clinic BP of 140/90 mmHg or higher) in 11 RCTs
200–800 mg nitrate a day · Varied across trials
Clinic systolic pressure fell 5.3 mmHg versus placebo; no significant effect on diastolic or 24-hour blood pressure. GRADE certainty low.
- CGrade CBlood pressure after short-term nitrate · Improved
Meta-analysis, 16 studies · n 254 · 2013 · Adults in 16 crossover RCTs
Varied; higher daily nitrate linked to larger systolic drops · 2 hours to 15 days
Systolic pressure fell 4.4 mmHg; the diastolic change (−1.1 mmHg) was not significant.
- CGrade CClinic, ambulatory and home blood pressure in hypertension · Improved
RCT · n 68 · 2015 · Adults with hypertension, half untreated and half on medication
250 mL/day · 4 weeks
Clinic BP fell 7.7/2.4, 24-hour BP 7.7/5.2 and home BP 8.1/3.8 mmHg versus placebo juice, with no fading over 4 weeks; endothelial function improved about 20%.
- CGrade CBlood pressure with 1–6 weeks of nitrate · Mixed
Meta-analysis, 13 studies · n 325 · 2017 · Adults in 13 RCTs
Varied across trials · 1–6 weeks
Systolic fell 4.1 and diastolic 2.0 mmHg overall, but only in clinic measurements; 24-hour ambulatory and home monitoring showed no significant change.
