Can You Eat Beets Every Day? What the Evidence Actually Shows
Daily beets are safe for most people, and the benefits are real but small. What two 2026 meta-analyses found about performance and blood pressure, plus who should be careful.
The short answer: yes, eating beets daily is safe for most people, and the measured benefits are real but small. A 2026 meta-analysis of 38 studies in 703 people found beetroot juice improved VO₂max by a standardised mean difference of just 0.24 (95% CI 0.11–0.37), with no clear effect in highly trained athletes (Qin & Kim, Front Nutr, 2026).
Beetroot is a dietary source of inorganic nitrate, which the body converts through nitrite into nitric oxide — a signalling molecule that widens blood vessels and is the mechanism behind almost every beetroot health claim.
The key numbers, with sources
- SMD 0.24 (95% CI 0.11–0.37). The pooled effect of beetroot juice on VO₂max/VO₂peak across 38 studies and 703 participants — statistically significant, but small (Qin & Kim, Front Nutr, 2026; certainty rated moderate).
- SMD 0.07 (95% CI −0.09 to 0.23). The same effect in highly trained athletes — not clearly demonstrated. The benefit concentrated in recreationally active people (SMD 0.38).
- SMD 0.19 after correction. Funnel-plot asymmetry suggested publication bias; after trim-and-fill the effect shrank but stayed significant.
- 6.4–12.8 mmol nitrate, 3+ consecutive days. The dosing window that showed the most consistent effects in that review.
- No significant blood-pressure change. A separate 2026 meta-analysis of chronic nitrate supplementation (6 studies, n=181, aged over 50) found no significant reduction in systolic BP (MD −3.81 mm Hg, 95% CI −10.05 to 2.43) or diastolic BP (MD −2.00, 95% CI −4.37 to 0.38) (Forster et al., Nutr Res, 2026).
Is it safe to eat beets every day?
For most healthy people, yes. Beets are an ordinary vegetable, and nothing in the recent literature flags daily culinary intake as harmful. The practical issues are minor and mostly cosmetic.
The most common surprise is beeturia — pink or red urine, and sometimes reddish stools, after eating beets. It is caused by the pigment betanin passing through unchanged, it is harmless, and it happens to a sizeable minority of people. It is worth knowing about only so it is not mistaken for blood.
Who should be more careful?
- People who form calcium-oxalate kidney stones. Beets are high in oxalate. Dietary oxalate is one of the levers clinicians adjust for recurrent calcium stone formers — the American Urological Association’s 2026 guideline covers dietary management of this group. If you have had stones, this is a conversation with your doctor, not a decision to make from an article.
- Anyone on blood-pressure medication. Nitrate is vasodilatory in principle. The chronic-supplementation evidence above did not find a significant group-level effect, but if you take antihypertensives, mention a new daily beetroot habit to your prescriber.
- People using concentrated beetroot shots rather than food. The trial doses (6.4–12.8 mmol nitrate) come from concentrated juice, not from a side of roasted beets. Supplement doses are a different exposure from vegetables.

What does beetroot actually do for performance?
It produces a small, real improvement in aerobic capacity for ordinary exercisers, and probably nothing for well-trained athletes. That is an unusual pattern worth understanding: trained athletes already have high nitric oxide bioavailability, so there is less headroom for nitrate to add anything.
Qin and Kim pooled 38 randomised and crossover placebo-controlled trials. The overall effect was SMD 0.24. Split by training status, it was 0.38 in recreationally active participants and 0.07 — with an interval crossing zero — in highly trained athletes.
| Claim | What the evidence shows | Strength |
|---|---|---|
| Improves aerobic capacity (VO₂max) | Yes, but small: SMD 0.24 across 38 studies; 0.19 after adjusting for publication bias | Moderate certainty |
| Works for trained athletes | Not clearly demonstrated (SMD 0.07, CI crosses zero) | Moderate certainty |
| Lowers blood pressure long term | A 2026 meta-analysis of chronic nitrate supplementation found no significant change in systolic or diastolic BP | Six studies, n=181, low risk of bias |
| Turns urine pink | Yes — beeturia, harmless | Well described |
| Raises oxalate intake | Yes — relevant only to calcium-oxalate stone formers | Clinical guideline territory |
So does beetroot lower blood pressure or not?
This is where the popular claim runs ahead of the current evidence, and the detail matters. Single-dose studies have repeatedly shown short-term blood-pressure dips after nitrate. The question is whether that persists with ongoing use.
Forster and colleagues pooled six randomised placebo-controlled trials of chronic nitrate supplementation lasting at least a week, in 181 adults over 50. None of the three outcomes reached significance: systolic BP, diastolic BP or resting heart rate. Risk of bias across the included trials was low.
Two honest caveats. That review used sodium nitrate and deliberately excluded beetroot juice trials, so it is evidence about nitrate rather than about beets. And six studies in 181 people is a small base — an absent effect here is not the same as a proven absence of effect.
How should you actually eat them?
As food, regularly, without ceremony. Whole beets deliver nitrate alongside fibre, folate and potassium, which concentrated shots do not. The performance trials used concentrated juice because they needed a controlled dose, not because juice is superior nutritionally.
If you are using beetroot specifically before exercise, the review found the most consistent effects with 6.4–12.8 mmol of nitrate taken for at least three consecutive days — a loading pattern, not a single pre-workout shot. And set expectations by the effect size: this is a small edge, best seen alongside zone 2 cardio and the things that actually move VO₂max.
What this evidence does not show
- That beetroot is a blood-pressure treatment. The chronic-supplementation meta-analysis found no significant effect, and nothing here should replace prescribed medication.
- That more is better. No trial tested escalating daily intake, and the dosing window above comes from short supplementation protocols.
- That trained athletes should bother. The pooled effect in that group was 0.07 with an interval crossing zero.
- That beets are unique. Nitrate is also abundant in rocket, spinach and other leafy greens. See anti-inflammatory foods.

Frequently asked questions
Can you eat beets every day?
For most healthy people, yes. Beets are an ordinary vegetable and daily culinary intake is not flagged as harmful in the recent literature. Two groups should take more care: people who form calcium-oxalate kidney stones, because beets are high in oxalate, and anyone taking blood-pressure medication, who should mention the habit to their prescriber.
Can you eat too many beets?
There is no established upper limit for beets as food. The practical ceiling for most people is gastrointestinal comfort and, for recurrent calcium-oxalate stone formers, oxalate load. Concentrated beetroot shots are a different matter from whole vegetables, since trial doses of 6.4 to 12.8 mmol nitrate come from concentrated juice rather than from a normal portion.
Why does beetroot turn your urine pink?
That is beeturia, caused by the pigment betanin passing through the gut and kidneys unchanged. It is harmless and affects a sizeable minority of people. The only reason to know about it is so that pink or red urine after eating beets is not mistaken for blood.
Does beetroot juice actually improve performance?
A little, and mainly if you are not already highly trained. A 2026 meta-analysis of 38 studies in 703 people found a small but significant improvement in VO2max (SMD 0.24, 95% CI 0.11 to 0.37). In recreationally active people the effect was 0.38; in highly trained athletes it was 0.07 with a confidence interval crossing zero.
Does beetroot lower blood pressure?
Less reliably than commonly claimed. A 2026 meta-analysis of six randomised trials of chronic nitrate supplementation in 181 adults over 50 found no significant reduction in systolic blood pressure (MD -3.81 mm Hg, 95% CI -10.05 to 2.43) or diastolic. That review tested sodium nitrate and excluded beetroot juice studies, so it is evidence about nitrate rather than beets directly.
