Beetroot Juice and Blood Pressure Medication: What to Know
Beetroot juice can lower your blood pressure on its own, so drinking it while you take blood pressure medication can stack the two effects and push your pressure too low, which may cause dizziness, fainting, or falls. For most people it is fine to have beet juice with blood pressure medicine. The key rules: keep taking your prescribed medication, add beet juice slowly, and check your numbers at home. Do not stop your medication just because your readings improve.

Why beet juice is not just an innocent smoothie add-on
You probably saw a video promising that beet juice "naturally" lowers blood pressure. Here is the surprising part: that claim is actually backed by real science. Beet juice genuinely moves the number.
That is exactly why it deserves respect if you already take medication. When something that lowers your blood pressure gets added to something else that lowers your blood pressure, the two can add up. A little extra drop is usually harmless. A bigger drop can leave you lightheaded when you stand, especially if you are over 50.
So this is not a "beets are dangerous" story. It is a "beets work, so treat them like they work" story. Below is what the strongest studies found, why beet juice and your prescription pull in the same direction, and how to enjoy beets without overshooting.
What the double-blind trials actually measured
The best evidence here comes from randomized, double-blind trials, where neither the patients nor the researchers knew who got real beet juice versus a placebo. Here is what they found.
| Study | Who was studied | Systolic drop |
|---|---|---|
| Kapil 2015 | 68 people with high blood pressure, half already on BP medication, 4 weeks | About 7.7 mmHg lower over 24 hours |
| Benjamim 2022 | Pooled 7 trials, 218 patients who all had high blood pressure | About 4.95 mmHg lower |
| Siervo 2013 | Pooled 16 trials across adults in general | About 4.4 mmHg lower |
| Kukadia 2019 | 15 healthy young adults with normal blood pressure | Brief early dip, but no real 24-hour effect |
The headline trial is Kapil 2015, which followed 68 people with high blood pressure for four weeks. Their 24-hour blood pressure fell by about 7.7/5.2 mmHg, and the effect held all month. What makes this study special for you: half of the people in it were already taking blood pressure medication. So this was not a "beets instead of pills" test. It was closer to a "beets on top of pills" picture, which is the exact situation you are in.
Zoom out to the pooled data and the number settles around a modest 4 to 5 points of systolic (top number) drop. A meta-analysis of seven trials in people with high blood pressure, Benjamim 2022, found about 4.95 mmHg. An earlier review of 16 trials, Siervo 2013, landed near 4.4 mmHg. The effect is real, but it is a nudge, not a cliff.
There is an honest catch. In Kukadia 2019, healthy young adults with normal blood pressure had only a brief early dip and no meaningful 24-hour change. Translation: beet juice mainly moves the needle in people who already have elevated pressure. If that is you, plan for a real effect.
Why beet juice adds to your prescription
Beet juice and blood pressure medicine can stack because, in the end, many of them do the same thing to your body: they relax and widen your blood vessels.
Beetroot is rich in a compound called dietary nitrate. As Gee and Ahluwalia 2016 explain, your body turns that nitrate into nitrite and then into nitric oxide, a molecule that tells your blood vessels to open up. Wider vessels mean less pressure inside them. Several common blood pressure drug classes reach that same "relax the vessels or reduce the load" endpoint by a different route. When both arrive at once, the effects add together.
Here is how that additive direction looks across the main drug classes. This is about direction, not doses, so never change your dose based on it.
| Drug class (examples) | How it lowers your pressure | What beet juice can add | What to watch |
|---|---|---|---|
| ACE inhibitors (lisinopril, ramipril) | Relax blood vessels by blocking a vessel-tightening hormone | More vessel widening from nitric oxide | Dizziness when standing up |
| ARBs (losartan, valsartan) | Block the same vessel-tightening signal at the receptor | More vessel widening on top | Lightheadedness, tiredness |
| Calcium channel blockers (amlodipine) | Relax the muscle in vessel walls | Vessels relax even further | Flushing, swelling, feeling faint |
| Beta-blockers (metoprolol, atenolol) | Ease the heart's workload and output | Lower vessel resistance stacked on lower output | Fatigue, dizziness, slow feeling |
| Diuretics (hydrochlorothiazide) | Remove extra fluid and salt | Added vessel relaxation | Dizziness, dehydration signs |
None of this means beets and blood pressure pills cannot mix. They usually can. It just means the combined effect can be a bit stronger than either alone, so introduce beet juice on purpose and keep an eye on how you feel.

Beet juice sits in the same family as other supplement swaps, like taking magnesium with blood pressure medication.
The falls risk if you are over 50
This part matters most for our readers in their 40s, 50s, and 60s. The same glass of beet juice tends to lower blood pressure more in older adults than in younger ones.
In Stanaway 2019, older adults aged 50 to 70 had a bigger rise in active nitrite and a meaningful drop in their bottom number, while younger adults showed no significant change from the same drink. A separate trial in adults aged 50 to 70 with elevated pressure saw sizable 24-hour drops over 60 days of daily beet juice, Siervo 2020.
Why care? A bigger, stacked drop is where dizziness on standing, near-fainting, and falls come from. This is not about fear. It is about giving your body a chance to adjust instead of surprising it.
You cannot see the dose in the glass
Here is a quiet problem: you have no easy way to know how much nitrate is in your beet juice. Nitrate content varies widely between products and is often not printed on the label at all.
Testing of commercial beet juices in Bescos 2023 found nitrate levels differed by roughly two-fold from brand to brand, ran about 34% higher in summer batches, and were disclosed on only two of five products tested. So the "dose" you stack onto your medication changes from bottle to bottle and even from season to season. That is one more reason to lean on your own home readings, like the label-detective habit in our electrolyte powder and blood pressure medication guide.
How to add beet juice safely while on BP meds
You do not have to choose between beets and your prescription. You just add one carefully around the other.
- Keep taking your prescribed medication on schedule. Your pills are the foundation. Beet juice is a maybe-helpful extra, not a replacement. If you tend to forget doses, our missed dose of blood pressure medication guide covers how to get back on track.
- Add it slowly and consistently. Start with a small, steady daily amount rather than a giant glass once in a while. Consistency lets you and your doctor see a clear pattern.
- Check your blood pressure at home. Take a reading before you add beets and keep a simple log afterward. Watch for numbers that drift lower than your target.
- Notice how you feel when you stand. Dizziness, lightheadedness, blurry vision, or feeling faint when you rise are the signals to slow down and call your doctor or pharmacist.
- Bring your log to your next visit. If your numbers keep improving, your doctor is the one who decides whether your medication needs adjusting. That decision is never yours to make alone.
Do not stop your medication because your numbers look great
This is the single most important warning in this article. If your readings improve after adding beet juice, that improvement is very likely the medication and the beet juice working together. Pull out the medication and you remove the foundation holding everything up.
Stopping blood pressure medicine on your own can send your pressure back up, sometimes sharply. See what actually happens when people stop taking blood pressure medication, and why blood pressure pills are on the list of medications you should never skip without medical guidance. Good numbers are a reason to celebrate and keep going, not a reason to quit.
How Pillo helps you keep the foundation steady
The whole safe-beet-juice plan rests on one thing: still taking your prescribed medication reliably while you experiment with diet. That is exactly the "I felt better so I skipped it" drift that quietly undoes progress.
Pillo's persistent alarm keeps ringing until you actually deal with your dose, so a good reading last week does not turn into a missed pill this week. You can also log your home blood pressure right in the app, next to your medication history, so you and your doctor can see whether beet juice really moved your numbers or you simply took your medicine on time. If you take a once-daily pill like amlodipine, our best time to take amlodipine guide pairs well with a steady beet-juice habit.
Download Pillo on Google Play and let the reminders hold the line while you fine-tune the rest with your care team.
Frequently Asked Questions
Can I stop my blood pressure medication if beet juice lowers my numbers?
No. Better numbers after adding beet juice usually mean the medication and the juice are working together, not that you no longer need the pills. Stopping your medication on your own can send your blood pressure back up, sometimes quickly. Only your doctor can decide whether a dose should change, based on your home readings and exam.
How much beet juice is too much with blood pressure medication?
There is no single safe number, partly because nitrate content varies a lot between brands and is often unlabeled, as shown in Bescos 2023. The safer approach is to start small, keep the amount steady day to day, and watch your home blood pressure. If you feel dizzy, lightheaded, or faint when standing, cut back and check with your doctor or pharmacist.
Which blood pressure drugs interact with beet juice?
Beet juice can add to the effect of all the major classes, including ACE inhibitors, ARBs, calcium channel blockers, beta-blockers, and diuretics, because beet juice and these medicines both end up relaxing your blood vessels or easing your heart's load, as described in Gee and Ahluwalia 2016. The result is usually a small extra drop in pressure. The main thing to watch across every class is feeling faint or dizzy when you stand.
Can beet juice make my blood pressure too low or cause dizziness?
It can, especially if you are older or already at your target. Beet juice tends to lower blood pressure more in adults over 50, per Stanaway 2019, so stacking it on medication can occasionally overshoot. Dizziness, lightheadedness, or near-fainting when you stand up are the warning signs to slow down and call your doctor.
Does beet juice work the same for everyone?
No. The effect is strongest in people who already have elevated blood pressure and is often modest, around 4 to 5 points of systolic drop in pooled trials like Benjamim 2022. In healthy young adults with normal pressure, the sustained effect can wash out entirely, as seen in Kukadia 2019. Your own response is best judged by your home readings, not a headline.
