Quick answer
Beetroot can lower blood pressure. The active part is dietary nitrate, not the red color. A dose of about 300 to 600 mg nitrate (roughly 70 to 140 ml of concentrated beetroot juice) drops systolic pressure by around 3 to 5 mmHg in healthy and mildly hypertensive adults. The effect peaks 2 to 3 hours after intake and fades within 24 hours. So timing and consistency matter.
This is moderate evidence. It works best as a daily habit, not a one-time fix.

How beetroot lowers blood pressure
Beets are rich in inorganic nitrate. Your body converts it through a simple path: nitrate to nitrite to nitric oxide.
Nitric oxide relaxes the smooth muscle in your blood vessel walls. The vessels widen. Pressure drops. This is the same molecule your body makes naturally to manage circulation.
Bacteria in your mouth do the first conversion step. That detail matters, and we will come back to it.
What the research shows
A 2013 meta-analysis in the Journal of Nutrition found beetroot juice lowered systolic blood pressure by about 4.4 mmHg on average (PubMed). Larger and longer trials show smaller but real effects, often 3 to 5 mmHg systolic.
That may sound small. But a 5 mmHg systolic drop across a population links to meaningful reductions in stroke and heart disease risk. For one person, it is a modest, supportive nudge.
Grade: moderate evidence for short-term blood pressure reduction. Long-term outcome data (actual heart events) is still limited.
The right dose
The target is nitrate, not grams of beet. Products vary a lot, so read the label for nitrate content.
| Form | Typical nitrate dose | Notes | |------|---------------------|-------| | Concentrated beetroot juice | 300 to 600 mg per 70 to 140 ml | Most studied form | | Beetroot powder | 300 to 500 mg nitrate per serving | Check the label; varies widely | | Whole cooked beets | ~200 to 400 mg per 200 g | Cooking lowers nitrate somewhat | | Beetroot capsules | Often low nitrate | May be too weak unless standardized |
Many cheap beet powders list grams of beet but not nitrate. If the nitrate amount is missing, you cannot dose it properly. Look for a standardized nitrate figure.
Timing and the nitrate window
This is where most people get it wrong.
Nitric oxide from a beet dose rises within 2 to 3 hours, then declines. By 24 hours, the effect is mostly gone. So a single serving does not give lasting protection.
Practical timing
- For daily blood pressure support: take it once a day, same time, every day.
- For exercise or a workout: take it 2 to 3 hours before activity, when nitric oxide peaks.
- Consistency beats perfection. The blood pressure benefit builds with regular daily use.
The mouthwash mistake
Your oral bacteria do the first conversion of nitrate to nitrite. Antibacterial mouthwash kills those bacteria. Studies show mouthwash use can blunt or erase the blood pressure benefit of beetroot (PubMed).
If you take beetroot for blood pressure, skip the antiseptic mouthwash. This is one of the most overlooked details.
Who should be careful
Beetroot is food, and broadly safe. But a few flags matter.
- On blood pressure medication? Beetroot can add to the effect. Tell your doctor before combining. Watch for dizziness or lightheadedness.
- Kidney stones: beets are high in oxalate. If you form calcium oxalate stones, go easy.
- Pregnancy: food amounts are fine. Concentrated supplement doses are not well studied. Ask your provider.
- Beeturia: your urine and stool may turn pink or red. This is harmless and not blood.
- Low blood pressure: if yours runs low already, beetroot may push it lower than you want.
Beetroot vs other circulation supplements
Beetroot is not the only option, and it is not always the best one for a given goal.
| Supplement | Best for | Evidence | Typical dose | |-----------|----------|----------|-------------| | Beetroot (nitrate) | Blood pressure, exercise blood flow | Moderate | 300 to 600 mg nitrate daily | | L-Arginine | Nitric oxide via a different path | Mixed/moderate | 3 to 6 g daily | | CoQ10 | Blood pressure, statin users, energy | Moderate | 100 to 200 mg daily | | Magnesium | Blood pressure if you are low | Moderate | 200 to 400 mg daily |
Beetroot and L-arginine raise nitric oxide through separate routes. Some people stack them, but evidence for the combo is thin. Start with one.
If you are on a statin, CoQ10 has separate support worth a look. You can browse the heart and circulation range at Meo to compare.
What beetroot will not do
Let us be honest about limits.
- It will not replace blood pressure medication. A 3 to 5 mmHg drop is real but modest.
- It will not fix high blood pressure caused by poor diet, weight, or inactivity on its own.
- It will not work well if you use antiseptic mouthwash daily.
- The effect does not stack endlessly. More nitrate above the studied range does not mean more benefit, and very high intake raises other concerns.
Think of beetroot as one supporting piece. Diet, sodium, sleep, and movement do the heavy lifting.
How to use it well
- Pick a product with a stated nitrate amount near 300 to 600 mg.
- Take it at the same time daily.
- Skip antibacterial mouthwash.
- Track your blood pressure at home over 4 to 8 weeks.
- Tell your doctor if you take BP meds.

FAQ
How long does it take beetroot to lower blood pressure?
The nitric oxide effect peaks 2 to 3 hours after a dose. For a steadier blood pressure benefit, take it daily for 4 to 8 weeks and track your numbers. A single serving helps short-term but fades within 24 hours.
How much beetroot juice should I drink for blood pressure?
Studies use about 70 to 140 ml of concentrated beetroot juice, supplying roughly 300 to 600 mg of nitrate. The nitrate amount matters more than the volume, so check the label rather than guessing by color or taste.
Can I take beetroot with blood pressure medication?
Possibly, but talk to your doctor first. Beetroot can add to the effect of your medication and cause dizziness or readings that drop too low. Your provider may want to monitor your blood pressure more closely at first.
Does beetroot powder work as well as juice?
It can, if the powder is standardized for nitrate content. Many powders list grams of beet but not nitrate, so you cannot dose them reliably. Choose a product that states its nitrate amount per serving.
Why does mouthwash reduce the effect?
Bacteria in your mouth convert nitrate to nitrite, the first step toward nitric oxide. Antiseptic mouthwash kills those bacteria and blunts the blood pressure benefit. If you use beetroot for circulation, avoid antibacterial mouthwash.
