After ingestion, nitrate is reduced to nitrite by bacteria on the tongue and is then converted in the body to nitric oxide, a signaling molecule that relaxes blood vessels (vasodilation) and increases blood flow. This nitrate-nitrite-nitric oxide pathway is thought to underlie beetroot's effects on blood pressure, vascular function and the oxygen cost of exercise. Other leafy vegetables such as spinach, rocket and celery are also high in nitrate. ## Its role in longevity 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 alongside improved endothelial function and reduced arterial stiffness. An umbrella review of 20 meta-analyses also found improved exercise time-to-exhaustion, muscular endurance and peak power, particularly at nitrate doses of 6 mmol or more per day, and several studies suggest older adults may benefit through improved vascular and muscle function. However, the evidence is honestly mixed: most trials are small and short, individual responses vary widely, diastolic effects are inconsistent, trials in COPD and a 13-week cognition study found no benefit, and no trial has tested long-term outcomes such as stroke or heart attack. The effect also depends on oral bacteria that convert nitrate to nitrite—antiseptic mouthwash largely abolishes it. Betalain pigments and other beetroot compounds may add antioxidant effects beyond nitrate. This evidence describes inorganic nitrate and the beetroot / nitrate mechanism in general, not this specific commercial product. ## Evidence grade: Moderate evidence - **What the grade means:** Curated grade based on the human and mechanistic evidence for this compound. - **Dose used in studies:** Trials use ~70–250 mL beetroot juice or concentrate delivering roughly 4–13 mmol (about 250–800 mg) nitrate per day; a typical beet shot provides ~6.4 mmol (~400 mg). - **Dose from food:** Fully food-based: one cup of cooked beets, or ~100 g of arugula (~480 mg nitrate) or raw spinach (~250 mg), provides nitrate in the same range as the studied juice doses. - **What this grade does not say:** Concordant meta-analyses and a pivotal RCT in hypertensives show roughly 5-8 mmHg systolic BP reductions and improved vascular function, plus modest exercise-performance gains. Most trials are small and short, diastolic effects are inconsistent, individual responses vary, and long-term outcomes (stroke, heart attack) are untested. Antiseptic mouthwash blocks the effect by killing the oral bacteria that activate nitrate. ## Where it comes from without a bottle Food, exercise and behaviour routes to the same pathway, each with its citation. | Natural source | How it works | Citation | | --- | --- | --- | | Green leafy vegetables (arugula, spinach) | Leafy greens are the biggest dietary source of the same inorganic nitrate as beets — about a cup a day tracked with lower blood pressure and cardiovascular risk. | European Journal of Epidemiology 2021 [PMID 33884541](https://pubmed.ncbi.nlm.nih.gov/33884541/) | | Beets & nitrate-rich produce | Your nitrate stores rise quickly with nitrate-rich foods like beets and greens; mouth bacteria convert it to nitrite, then nitric oxide, lowering blood pressure. | Med Sci Sports Exerc 2021 [PMID 32735111](https://pubmed.ncbi.nlm.nih.gov/32735111/) | | Beetroot juice (whole-food form) | Drinking nitrate-rich beetroot juice reliably raises plasma nitrate and nitrite — the active route behind dietary nitrate's effects on circulation and exercise. | Journal of Physiology 2021 [PMID 34587650](https://pubmed.ncbi.nlm.nih.gov/34587650/) | ### What those papers actually say 1. **Green leafy vegetables (arugula, spinach)** European Journal of Epidemiology 2021 · [PMID 33884541](https://pubmed.ncbi.nlm.nih.gov/33884541/) · [DOI 10.1007/s10654-021-00747-3](https://doi.org/10.1007/s10654-021-00747-3) > Consumption of at least ~60 mg/day of vegetable nitrate (~1 cup of green leafy vegetables) may mitigate risk of CVD 2. **Beets & nitrate-rich produce** Med Sci Sports Exerc 2021 · [PMID 32735111](https://pubmed.ncbi.nlm.nih.gov/32735111/) · [DOI 10.1249/MSS.0000000000002470](https://doi.org/10.1249/MSS.0000000000002470) > dietary nitrate supplementation with beetroot juice lowers blood pressure in hypertensive patients 3. **Beetroot juice (whole-food form)** Journal of Physiology 2021 · [PMID 34587650](https://pubmed.ncbi.nlm.nih.gov/34587650/) · [DOI 10.1113/JP281995](https://doi.org/10.1113/JP281995) > Compared with PLA, NO3 increased plasma levels of nitrate and nitrite ## In the news - **Nitrate in beetroot juice lowers blood pressure, study finds** — ScienceDaily (Queen Mary, University of London) 2010 [Read it](https://www.sciencedaily.com/releases/2010/06/100628161123.htm) > The study, published online in the American Heart Association journal Hypertension, found that blood pressure was lowered within 24 hours in people who took nitrate tablets, and people who drank beetroot juice. - **Can beetroot juice lower blood pressure?** — British Heart Foundation 2024 [Read it](https://www.bhf.org.uk/informationsupport/heart-matters-magazine/nutrition/can-beetroot-juice-lower-blood-pressure) > There's a lot of marketing about beetroot juice's benefits but there is not yet enough scientific evidence to give specific dietary recommendations. ## The research Peer-reviewed studies on the active compound.
