The short answer
Nitrate-rich beetroot juice can lower blood pressure, but studies have not established harmful low blood pressure specifically when it is combined with enalapril. Results vary by preparation and study. Ask for advice before adding a concentrated beetroot or nitrate product to your treatment.
What this answer covers
Oral Beta vulgaris preparations with oral enalapril. The strongest relevant studies used nitrate-rich beetroot juice, not every beet product. A separately added nitrate supplement is a different exposure and is not silently included in this pair.
- Supplement or preparation
- Beetroot (Beta vulgaris)
- Medication ingredient
- enalapril
What did the longer juice trial find?
A four-week trial used 250 mL of nitrate-rich beetroot juice daily in 68 people with hypertension. Half were already taking blood-pressure medicines. Average clinic and 24-hour pressure fell compared with nitrate-depleted juice. The published abstract described good tolerability but did not provide an enalapril-specific safety result.
Why is the effect uncertain?
In another study of 27 people with treated hypertension, one week of nitrate-rich juice increased nitrate-related blood measurements without lowering home or 24-hour pressure compared with placebo. The shorter duration and different participants may matter. Neither study determines how your pressure will respond or proves the exact combination safe.
Are beetroot and nitrate the same exposure?
No. The juice studies compared products with and without nitrate. A beet capsule may contain a different amount, and a separate nitrate supplement adds another exposure. Do not assume that a label saying beetroot matches the trial preparation or that combining two nitrate sources has been tested.
How should I approach a new product?
Discuss the product label, daily amount and recent blood-pressure readings with your pharmacist. Enalapril-related low pressure is more likely with dehydration or certain diuretics, so mention these too. No proven spacing interval for beetroot was identified. Do not use juice or capsules as a replacement for prescribed enalapril.
Evidence and practical considerations
Side effects & toxicity
Nitrate-rich beetroot juice can lower blood pressure, but studies have not established harmful low blood pressure specifically when it is combined with enalapril. Results vary by preparation and study. Ask for advice before adding a concentrated beetroot or nitrate product to your treatment.
- Exact scope
- Oral Beta vulgaris preparations with oral enalapril. The strongest relevant studies used nitrate-rich beetroot juice, not every beet product. A separately added nitrate supplement is a different exposure and is not silently included in this pair. with Enalapril, RxCUI 3827, IN. Oral enalapril maleate tablets are an explicitly identified salt formulation of enalapril in the label. This bridge applies to the labeled oral prodrug; injected enalaprilat, other ACE inhibitors and combination products are not assigned this evidence automatically.
- Medication form and route
- oral
- Timing or duration
- Limited to the exposure durations described in the sources; no untested duration or timing rule is inferred.
What remains uncertain
- Related trials disagree about blood-pressure lowering across exposures, but none establishes or refutes excess symptomatic hypotension for enalapril. The original statement mixes Beta vulgaris with separately named nitrate; exact product composition is required.
Factors that may matter: exact preparation and dose; baseline blood pressure; kidney function; diuretics and other medicines; dehydration.

Source 1: regulatory prescribing information
dailymed.nlm.nih.gov · Source check Sep 10, 2026
Population: Patients prescribed oral enalapril maleate for hypertension or heart failure.
Potassium products can substantially increase serum potassium; when indicated for documented low potassium, use cautiously with frequent testing. Dehydration and intensive diuretic treatment increase hypotension risk.
How this applies: The maleate formulation is explicitly identified as a salt of enalapril. Applies to oral enalapril, RxCUI 3827 IN; does not transfer to injected enalaprilat or another ACE inhibitor.
A drug label supports named warnings, not every botanical combination. Trial hyperkalemia rates are for enalapril treatment and do not quantify the incremental risk of potassium supplements. The inspected US label has no antacid-specific paragraph.
Source 2: primary randomized controlled trial
pubmed.ncbi.nlm.nih.gov · Source check Sep 10, 2026
Population: 68 hypertensive adults randomized, including 34 receiving blood-pressure medicines and 34 untreated.
Clinic pressure fell by a placebo-adjusted 7.7/2.4 mmHg; 24-hour pressure by 7.7/5.2 mmHg. Intervention was described as well tolerated.
How this applies: Applies to nitrate-containing beetroot juice, a defined Beta vulgaris preparation. It does not validate the original compound claim for beet plus a separately added nitrate product.
The verified abstract does not give an enalapril-specific subgroup or establish symptomatic hypotension. Not a comparison of every beet extract, nitrate salt, vegetable portion or high-dose combination.
Source 3: primary randomized controlled trial
pubmed.ncbi.nlm.nih.gov · Source check Sep 10, 2026
Population: 27 men and women with treated hypertension in a randomized crossover trial.
Plasma, saliva and urine nitrate/nitrite increased, but home and 24-hour blood pressure did not differ from placebo.
How this applies: Contrasting blood-pressure result for a specified beetroot juice exposure, not an enalapril-specific harm assessment.
Short study; medication-specific results and exact nitrate dose were not verified in abstract-only access. Does not refute longer treatment effects or prove combination safety.
