Beet chews work only if they deliver enough dietary nitrate—and many products fall short of the doses shown to improve exercise performance.
You’re eyeing that jar of beet chews for better endurance, a stronger finish, or an edge in training. Whether they deliver comes down to one thing: actual nitrate content. A ConsumerLab test found that some beet chews contain only single-digit milligrams of nitrate per chew—a tiny fraction of what research links to performance gains. Whether “effective” describes your experience depends almost entirely on the specific product you choose.
What The Research Actually Shows About Beetroot Nitrate
Beetroot’s performance credentials come from dietary nitrate, which your body converts to nitric oxide—a molecule that improves blood flow and muscle oxygenation. A 2022 meta-analysis of randomized trials found that dietary nitrate supplementation improved overall exercise performance, with the most consistent benefits for sessions lasting 2 to 10 minutes and when 5–14.9 mmol/day was taken at least 150 minutes before exercise.
Earlier meta-analyses reached a more cautious verdict: moderate benefit for time-to-exhaustion tests, but small or non-significant effects on time trials and graded exercise tests. One pooled analysis found no significant improvement in peak or mean power during high-intensity interval training and sprint interval training. Across all data, one pattern holds: the research was done overwhelmingly with beetroot juice and concentrated nitrate supplements, not chews.
Why Beet Chews Might Not Measure Up
The gap between research and product sits in dosing. ConsumerLab’s testing found that beetroot products vary more than 200-fold in nitrate content, and several chews tested contained single-digit milligrams per chew. To hit the 5 mmol/day associated with benefits, you’d need roughly 300 mg of nitrate—meeting that with a low-potency chew would require an impractical number of them.
That doesn’t mean all chews are useless. Products that genuinely deliver meaningful nitrate per serving can be a convenient alternative to jugging juice, so checking third-party test results or the manufacturer’s stated nitrate content matters more for chews than for nearly any other supplement format. If a product’s label and independent testing confirm meaningful nitrate per chew, it’s a reasonable delivery system. If the numbers are absent or unimpressive, you’re paying for a candy-like snack with negligible performance potential.

Timing, Dosing, And Who Benefits Most
Timing matters as much as dose. A 2022 meta-analysis found strongest effects when nitrate was taken at least 150 minutes before exercise, while a sports-science summary recommended at least 90 minutes before the event. The nitrate-to-nitrite conversion takes time, so a chew eaten right before a workout won’t give full benefit. Research suggests benefits are more consistent for recreationally active people than for elite endurance athletes, whose trained bodies may already be optimized. One review noted beetroot supplementation may improve oxidative metabolism and muscle force production, but effects depend on protocol and population. Oral hygiene also matters—antibacterial mouthwash can reduce the oral bacteria that convert nitrate to nitrite, blunting the effect.
Are There Any Downsides?
Nitrate is generally well tolerated, but there’s a dose ceiling. For a 70 kg person, that ADI equates to roughly 255 mg of nitrate per day, so a seriously high-dose chew or double serving could edge past it—exceeding the ADI is for the most part a theoretical rather than demonstrated risk, but very high nitrate intake isn’t studied for long-term safety.
| Factor | What Research Shows | Practical Takeaway |
|---|---|---|
| Nitrate dose needed | 5–14.9 mmol/day (≈300–900 mg) for best effects | Check the label—many chews fall far short |
| Timing before exercise | 90–150+ minutes | Don’t pop a chew right before you start |
| Exercise types helped most | 2–10 minute sessions, time-to-exhaustion | Best for hard efforts, not necessarily long steady runs |
| Who benefits | Recreationally active people | Elite athletes may see less effect |
| Variance between products | 200-fold difference in nitrate content | Product choice is everything |
The takeaway is direct: beet chews are effective only when they deliver enough nitrate. A low-dose chew is no more a performance supplement than a slice of bread. The brands that verify their nitrate content—and the third-party tests that confirm it—are the only ones worth considering. Pick a genuinely potent product, take it at least 90 minutes out, and you have a legitimate, convenient pre-workout strategy. Grab a low-nitrate chew at the checkout counter, and you’ve bought overpriced candy.
FAQs
How much nitrate do you need for beet chews to help?
Research points to roughly 5 mmol (about 300 mg) of nitrate for performance benefits. Many available chews contain far less per serving, so check the label or independent test results before relying on a particular product.
When should you take beet chews before a workout?
Most studies showing benefits had people take nitrate at least 90 to 150 minutes before exercise. That gives your body time to convert the nitrate into nitric oxide, which actually improves blood flow and endurance.
Do beet chews work for sprinting or weightlifting?
Evidence is mixed. Research found moderate benefits for time-to-exhaustion tests, but no significant improvement in peak or mean power for sprint interval training. Beet chews are more consistently helpful for sustained efforts of a few minutes than for explosive, maximal-power work.
