Does apple cider vinegar help with blood pressure? What the research does and doesn't show

The evidence doesn't support apple cider vinegar as a treatment for high blood pressure. A pooled analysis found a small average change linked to higher vinegar intake, rated low-certainty, from trials mostly built around other questions. The one trial designed to measure blood pressure directly, in people with type 2 diabetes, found no significant change at all.

What the evidence doesn't support

It doesn't support apple cider vinegar as a treatment for diagnosed hypertension, and it doesn't support a claim that a daily amount reliably brings a specific number down. Most of the trials behind the pooled estimate below were built to study weight, blood sugar or cholesterol, with blood pressure measured as a secondary outcome — not a trial designed and powered around blood pressure itself. No trial has enrolled people specifically because they have high blood pressure and followed them long enough to know whether an early change holds up.

What the trials found

A 2022 systematic review and dose-response meta-analysis pooled randomized trials of vinegar and blood pressure and estimated the change per 30 mL/day of vinegar consumed. Systolic pressure was on average 3.25 mmHg lower per 30 mL/day increment (95% CI: -5.54 to -0.96), and diastolic pressure was 3.33 mmHg lower (95% CI: -4.16 to -2.49). Both estimates were rated low-certainty by the GRADE framework, and the reduction leveled off beyond roughly 30 mL a day rather than continuing to grow with higher amounts. The trials pooled varied in population, dose and design, and most weren't measuring blood pressure as their primary outcome.

A separate randomized controlled trial gave 70 adults with type 2 diabetes and dyslipidemia either 20 mL of apple vinegar a day or a placebo for 8 weeks, tracking systolic and diastolic blood pressure alongside blood sugar and oxidative-stress markers. Fasting blood sugar and an oxidative-stress marker improved significantly in the vinegar group; blood pressure did not — no significant difference between the vinegar and placebo groups was found on either the systolic or diastolic reading.

Questions people ask

Does apple cider vinegar lower blood pressure?

A pooled dose-response analysis found a small average change linked to higher vinegar intake, rated low-certainty, from trials mostly built for other purposes. A trial that measured blood pressure directly as one of its outcomes, in people with diabetes, found no significant change over 8 weeks.

Can apple cider vinegar help with high blood pressure?

There's no trial testing apple cider vinegar in people specifically because they have high blood pressure, so there's nothing here that speaks to what it would do for that group over time.

Is apple cider vinegar good for blood pressure?

"Good for" isn't a question the current evidence can answer cleanly — the pooled estimate and the single dedicated trial point in different directions on how meaningful any change is, and neither is the kind of long, purpose-built trial that would settle it.

Does apple cider vinegar lower blood pressure immediately?

Nothing in the trials above measured an immediate, single-dose effect on blood pressure. Both studies tracked blood pressure over weeks of daily intake, not minutes or hours after a single serving.

When to talk to a doctor

High blood pressure is a diagnosis that needs monitoring and, often, medication — not a supplement search. Apple cider vinegar is not a treatment for hypertension, and nothing above supports using it in place of a prescribed blood pressure medication or a doctor's monitoring. If you take blood pressure medication or have been told your blood pressure is high, talk to your doctor before adding any new supplement.
