Yes: nitrate-rich beetroot juice lowers systolic pressure by about 5 mmHg in meta-analyses, working through nitric oxide, with larger effects in people who already have hypertension.
A 2024 meta-analysis found a 5.3 mmHg clinic systolic reduction versus placebo, sustained across interventions up to 90 days, and earlier analyses agree in the 4 to 5 point range. The mechanism is clean dietary science: beetroot nitrate converts to nitric oxide, which relaxes and widens vessels. The honest limits: a 5-point effect complements medication rather than replacing it; benefits fade when you stop; and nitrate content varies enough between products that dosing is approximate. Study patterns run about 250 to 500 ml of juice daily or an equivalent concentrate. One harmless shock to pre-answer: beeturia, pink-red urine or stool after beets, is pigment, not blood. On BP medication? Treat beetroot juice as a lifestyle layer your clinician knows about, never as a silent pill substitute.
What to do
Common questions
Does beetroot juice lower blood pressure?
Yes, and the mechanism is understood: beetroot is rich in dietary nitrate, which your body converts to nitric oxide, the molecule that tells blood vessels to relax and widen. The trial evidence is consistent. A 2024 meta-analysis in Nutrition, Metabolism and Cardiovascular Diseases found beetroot juice lowered clinic systolic pressure by about 5.3 mmHg versus placebo, with effects sustained up to 90 days in the included studies, and earlier meta-analyses landed in the same 4 to 5 point range, with bigger drops in people who already have hypertension. Keep the framing honest: 5 points is a genuine, useful effect (comparable to a low dose of one medication), but it is a complement to treatment, not a replacement for it in anyone with real hypertension. Practical notes: studies typically use about 250 to 500 ml of juice or an equivalent nitrate dose daily; effects on pressure begin within hours and fade if you stop; nitrate content varies wildly between juices, powders, and concentrates, so dosing is imprecise; and the harmless surprise is beeturia, pink or red urine and stools, which looks alarming and is not. If you are on blood pressure medication, add beetroot juice as a lifestyle layer and tell your clinician, rather than using it to quietly substitute for a pill.
