Beet Root Powder Benefits: 3 of 190 Labels Say How Much Nitrate
Quick Answer: Beet root powder’s benefits, for exercise, blood pressure and blood vessels, come from its nitrate, and the trials that found them used about 5 mmol (310 mg) of nitrate or more per dose. That is the problem with buying powder: we checked all 190 on-market products with “beet” in their name in the NIH Dietary Supplement Label Database, and only 3 state enough to work out their nitrate. The best gives about 70 mg a serving, less than a quarter of that minimum. Even among beet juices sold to athletes, nitrate varied about 50-fold between products. At a real dose, the benefits are measurable: 8.4 mmol let cyclists exercise 14% longer, and four weeks of nitrate-rich beetroot juice lowered 24-hour blood pressure by 7.7/5.2 mm Hg in people with hypertension, though a larger leafy-greens trial found no effect. Our product pick for this topic, CircO2, is in the box near the end of this page.
Beetroot is one of the richest food sources of nitrate, which your body converts into nitric oxide, the molecule that widens blood vessels. Powders, capsules and chews promise the same effect in a convenient form. Whether they deliver it depends almost entirely on a number most labels leave out. For the juice evidence specifically, see our page on beetroot juice for blood pressure and endurance.
What the benefits depend on: the nitrate dose
Nitrate is measured in millimoles (mmol) in research and milligrams on labels; 1 mmol of nitrate is 62 mg. The doses that matter:
| Dose | In mg of nitrate | What it did in trials |
|---|---|---|
| 4.2 mmol | About 260 mg | No change in exercise responses (Wylie 2013) |
| 5 mmol | About 310 mg | “The minimal dose required to enhance exercise performance in most individuals” (Gallardo 2019) |
| 8.4 mmol | About 520 mg | Time to exhaustion 14% longer; doubling to 16.8 mmol added nothing (Wylie 2013) |
| 200, 400, 800 mg | From beetroot powder | Arterial stiffness improved at all three; aortic systolic pressure fell only at 800 mg (McLellan 2026) |
What 190 beet product labels say
We searched the NIH Office of Dietary Supplements’ Dietary Supplement Label Database on 7 October 2026 for on-market products with “beet” in the product name and found 190: 82 powders, 54 capsules, 26 liquids, 14 tablets, 9 gummies and 4 others. Only six mention nitrate anywhere on the label, and only three give enough to calculate it:
| Product (as labelled) | Nitrate per serving, from the label | Share of the 310 mg minimum |
|---|---|---|
| VitaMonk OptiBeet (10 g) | 7,000 mg extract at 1% nitrate: 70 mg | 23% |
| X Gold Health Beet Root Extract “12000 mg” (2 capsules) | 600 mg of extract standardized to at least 4%: at least 24 mg | 8% |
| Irwin Naturals Beet Root RED (2 softgels) | 3 mg + 1.8 mg listed nitrate: 4.8 mg | 1.5% |
The other 187 do not state a nitrate amount we could calculate, including two Force Factor products whose labels name nitrate-standardized ingredients but give no quantity for them. Two things follow. First, a big milligram number on the front of a bottle is the weight of beet material, not of nitrate; the “12000 mg” product above provides at least 24 mg. Second, by comparison, a 100 g serving of rocket or spinach, at more than 2,500 mg of nitrate per kilogram, supplies more than 250 mg, as we set out in foods high in nitric oxide.
Juice is no guarantee either
Researchers at Indiana University tested 45 lots of 24 beetroot juice products from 21 companies. Nitrate varied about 50-fold between products, and by 30% on average between batches of the same product. Only five products consistently delivered at least 5 mmol per serving.
Benefit 1: exercise, at a real dose
In a crossover study of 10 healthy men, 70 mL of concentrated beetroot juice (4.2 mmol nitrate) did not change how their bodies responded to cycling. At 140 mL (8.4 mmol), time to exhaustion during hard cycling was 14% longer, and at 280 mL (16.8 mmol) 12% longer: no extra gain from doubling the dose. The effect is also smaller in very fit people, as we cover in nitric oxide benefits.
Benefit 2: blood pressure, where the evidence splits
Two well-run trials in people with raised blood pressure disagree:
- For: 68 people with hypertension drank 250 mL of nitrate-rich beetroot juice or a nitrate-free placebo juice daily for four weeks. Clinic pressure fell by 7.7/2.4 mm Hg, 24-hour pressure by 7.7/5.2 and home pressure by 8.1/3.8, with no sign of the effect wearing off. Blood-vessel function improved by about 20%.
- Against: 243 people aged 50 to 70 with raised pressure ate leafy greens supplying 300 mg of nitrate, or took 300 mg as pills, for five weeks. 24-hour systolic pressure did not change compared with placebo.
One difference is the form and dose: the positive trial used beetroot juice, the negative one leafy greens and nitrate pills at about 300 mg. The honest summary is that beetroot nitrate can lower blood pressure in some people with hypertension, but it is not a reliable replacement for treatment.
Benefit 3: arteries and blood vessels
A 2026 randomized crossover trial gave healthy adults nitrate-rich beetroot powder at 200, 400 and 800 mg of nitrate. Markers of arterial stiffness improved at all three doses. Blood-vessel dilation improved only at 400 mg (by 3.07%), and aortic systolic pressure fell only at 800 mg (by 4 mm Hg). Arm blood pressure did not change. This is one of the few trials to use powder rather than juice, and the doses that worked were far above what the labels in our survey state.
How to judge a beet root powder
- Look for nitrate in mg per serving, not beet root weight. If the label does not give it, you cannot know the dose.
- Compare with about 310 mg, the minimum that most exercise studies needed.
- Be wary of large front-of-pack numbers. “12000 mg” can mean a few hundred milligrams of extract.
- Consider food first. A large rocket or spinach salad can supply more nitrate than any labelled powder we found.
- Skip antiseptic mouthwash around the dose; the mouth bacteria that convert nitrate are part of how it works.

Frequently Asked Questions
What are the benefits of beet root powder?
Any benefits come from nitrate: longer endurance in exercise studies at about 8.4 mmol (520 mg), lower blood pressure in some people with hypertension, and improved arterial stiffness in a 2026 trial of beetroot powder at 200 to 800 mg of nitrate.
How much nitrate is in beet root powder?
Usually you cannot tell. Of 190 beet products in the NIH label database, only three stated enough to calculate it, and the highest was about 70 mg per serving.
Is beet root powder as good as beet juice?
It depends on the nitrate content, which varies widely in both. Juices sold to athletes varied about 50-fold, and only five of 24 consistently gave at least 5 mmol.
How much beet root powder should I take a day?
Enough to supply roughly 310 mg of nitrate or more, which is the dose most exercise studies needed. If the label does not state nitrate, there is no way to work out the right amount.
Does beet root powder lower blood pressure?
In a four-week trial of beetroot juice in people with hypertension, 24-hour pressure fell by 7.7/5.2 mm Hg. A larger trial of leafy greens and nitrate pills found no effect, so results are mixed.
When should I take beet root powder before exercise?
In the dose-response study, blood nitrite peaked about 2 to 3 hours after drinking beetroot juice, and the exercise tests were done 2.5 hours after the dose.
The Bottom Line
Beet root powder can only deliver the benefits seen in trials if it delivers the nitrate, about 310 mg or more per dose. Of 190 beet products we checked, three state enough to calculate it, and the best gives about 70 mg. If you want the nitrate effect, choose a product that states nitrate in milligrams, or eat leafy greens, which reliably supply it.
