Does pomegranate juice lower blood pressure?
Yes — across 14 randomised trials, drinking pomegranate juice lowered systolic blood pressure by about 5 mmHg, most clearly at around 1 cup a day and in people who already have raised blood pressure. The effect is on the top number; the bottom number moves less.
What the evidence supports
- ✓ Lower systolic BP ~5 mmHg across 14 juice trials1
- ✓ Clearest around 1 cup (≤300 mL) a day — about 6 mmHg at that dose
- ✓ It's the whole-fruit juice, at a food-level amount
- ✓ Several meta-analyses agree — roughly 5–8 mmHg systolic
What it doesn't do
- ✗ Show a clear effect in already-normal blood pressure — the evidence is in raised BP
- ✗ Keep building — the benefit attenuated after about two months
- ✗ Replace medication — it's a modest food effect
Where this comes from
- Why it works
- Pomegranate juice is rich in polyphenols — punicalagins and anthocyanins — which are thought to protect nitric oxide, the molecule that keeps blood vessels relaxed, and to have a mild ACE-lowering effect similar in direction to some blood-pressure drugs. The route is different from beetroot, whose effect runs mainly through dietary nitrate, which is why the two are assessed on their own trials rather than lumped together.
- What the human evidence shows
- The confirmed 2023 meta-analysis pooled 14 juice trials in 573 adults and found systolic pressure fell 5.02 mmHg (95% CI −7.55 to −2.48; p<0.001), with the effect tracking dose — about 6.1 mmHg at 300 mL a day or less, and no added systolic benefit above that.1 The drop was largest in the first two months. Two supporting trials read in full anchor it: a single 500 mL serving acutely lowered blood pressure in hypertensive men,2 and 100 mL three times a week over a year lowered systolic pressure in dialysis patients.3
- Where the evidence stops
- The trials are pomegranate juice, not extract capsules or the whole fruit, so the claim is specifically about the juice. The effect is established mainly in adults with elevated blood pressure or cardiometabolic risk; the evidence in healthy, normal-BP people is thin. And it is a systolic effect — the diastolic change was smaller and less consistent.
Why the juice, not an extract: the blood-pressure evidence is built on pomegranate juice, while most healthy-population studies that used concentrated extract capsules are a different thing — a supplement, outside a whole-food standard. We recommend no supplement, extract or supplement brand. Unsweetened juice is the form the trials support.

Bottom line for you
About a cup of pomegranate juice a day lowers the top number by roughly 5 mmHg, and the benefit is greatest if your blood pressure runs high. There is no advantage to drinking more than around 300 mL, and the juice — not an extract capsule — is what the trials support. Choose it unsweetened.
Treat it as one honest lever. The effect is modest, it is clearest on systolic pressure, it eased off somewhat after two months in the trials, and it does not replace medication or the bigger levers — weight, salt, exercise and alcohol. On medication? Raise it with your clinician rather than swapping anything yourself.
