Drinking beetroot juice every day with at least 397 mg of nitrate can lower high blood pressure as much as common blood pressure pills do.
Claim Language
Language Strength
definitive
Uses definitive language (causes, prevents, cures)
The claim uses 'significantly reduces' and 'comparable to', which imply a direct, measurable, and certain effect rather than a possibility or association. 'Significantly' is a statistical term often used in causal claims to assert a non-random, robust effect.

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (3)
Dietary nitrate provides sustained blood pressure lowering in hypertensive patients: a randomized, phase 2, double-blind, placebo-controlled study.
This study gave hypertensive people beetroot juice daily and found their blood pressure dropped significantly — similar to how common blood pressure pills work. So yes, beetroot juice can help lower blood pressure as much as some medicines.
Plasma nitrate, dietary nitrate, blood pressure, and vascular health biomarkers: a GRADE-Assessed systematic review and dose-response meta-analysis of randomized controlled trials
This study found that eating more nitrate-rich foods like beetroot juice lowers blood pressure a little bit, and the more you eat, the more it drops — which matches what the claim says. It didn’t directly compare it to pills, but the drop is big enough to be meaningful.
This study gave hypertensive women beetroot juice with lots of nitrates every day, and their blood pressure went down after just a week — similar to what the claim says. It doesn’t compare it to pills, but it still shows beetroot juice helps lower blood pressure.
Contradicting (2)
This study gave people a daily vegetable powder with lots of nitrate (like beetroot juice) and found it didn’t lower their blood pressure any more than a powder with very little nitrate — so it contradicts the claim that beetroot juice works like blood pressure medicine.
Increased nitrate intake from beetroot juice over 4 weeks affects nitrate metabolism, but not vascular function or blood pressure in older adults with hypertension
This study gave hypertensive older adults beetroot juice daily to see if it lowers blood pressure, like some pills do — but it didn’t. Even though their bodies processed the nitrate fine, their blood pressure stayed the same.
