Beetroot / Dietary Nitrate
A dietary nitrate source studied for blood pressure and exercise performance.
Evidence category: Systematic review. This describes the source category, not approval or certainty.
Regulatory statement in source: Not separately recorded; do not infer approval from the evidence category.
Beetroot, and the concentrated juice made from it, is a natural source of inorganic dietary nitrate that the body converts into nitric oxide, a molecule involved in blood vessel dilation. It has been tested in numerous randomized trials for effects on blood pressure and exercise performance, particularly in endurance and interval-based activities. Meta-analyses show a consistent, modest blood-pressure-lowering effect, while findings on exercise performance are more mixed and depend heavily on exercise type and training status.
Benefits reported in the imported source
- Randomized trials consistently show a modest reduction in blood pressure, particularly systolic pressure
- Some evidence supports improved intermittent running capacity in recreationally active people
- Whole-food source of nitrate with a well-understood mechanism through nitric oxide production
Risks and limits
- Effects on high-intensity power output in trained or elite athletes are largely absent in pooled analyses
- Urine and stool can turn red or pink after consumption, which is harmless but can be mistaken for a medical problem
- Long-term cardiovascular outcome data beyond blood pressure changes are limited
Source bottom line: Beetroot and dietary nitrate have some of the more consistent supplement evidence for blood pressure, but the exercise-performance story is uneven and depends heavily on the sport and the athlete's training level.

Study protocols — reports, not instructions
254 participants pooled across 16 randomized controlled trials of inorganic nitrate or beetroot juice versus placebo
- Reported regimen
- Inorganic nitrate or beetroot juice supplementation, from a single acute dose up to 15 days of daily dosing, compared with a nitrate-depleted placebo
- Duration
- Single acute dose up to fifteen days of daily dosing
- Reported outcome
- Supplementation was associated with a significant reduction in systolic blood pressure of about 4.4 mmHg, with a smaller and less consistent reduction in diastolic blood pressure.

Claim provenance
evidence.json#/catalog:supplement:beetroot/protocols/0
319 participants, mostly recreationally active adults, pooled across 17 randomized trials of high-intensity interval or sprint training
- Reported regimen
- Acute nitrate doses of about 4.8 to 12.9 mmol, or chronic daily doses of about 5.2 to 29.0 mmol for 3 to 28 days, most often given 2 to 3 hours before exercise
- Duration
- Three to twenty-eight days
- Reported outcome
- Beetroot supplementation produced no significant improvement in peak or mean power output during high-intensity interval or sprint training, though a small, significant improvement appeared on an intermittent running recovery test.
