Beetroot is one of the most researched ergogenic aids in cycling. It is not a stimulant. It does not cause a crash. Instead, it works by improving oxygen efficiency at the cellular level.
For cyclists, this translates to a measurable advantage: you hold a higher power output for the same oxygen cost.
This guide breaks down exactly what the data shows for cycling, how to time your dose, and the one caveat every elite cyclist needs to know.

Why Beetroot Works for Cyclists
Beetroot is rich in dietary nitrate. When you consume it, oral bacteria convert the nitrate to nitrite. This is then reduced to nitric oxide (NO) in your bloodstream.
Nitric oxide acts as a vasodilator. It relaxes your blood vessels, improving blood flow and oxygen delivery to working muscles.
The result is a lower oxygen cost at a given wattage. Your muscles extract oxygen more efficiently, allowing you to sustain higher power outputs before fatigue sets in.
(Note: This effect relies on the full whole-root matrix. Isolated nitrate salts have not shown the same benefit in cycling trials.)

What the Data Shows for Cycling
The research on beetroot and cycling is extensive. Here are the most relevant findings for your performance:
1. Power Output Increases (1.2–3.0%)
A 2026 review specifically analyzing cycling performance found that beetroot supplementation results in power output improvements ranging from 1.2% to 3.0% . In a sport often decided by seconds, a 3% increase in sustained power is a massive advantage.
2. Oxygen Cost Reduction (1.5–5.0%)
The foundational benefit. A review of endurance sports found that beetroot juice reduces the submaximal oxygen cost of exercise by 1.5–5.0% . You are literally using less oxygen to produce the same watts.
3. Time Trial Performance
A meta-analysis found that nitrate supplementation improved power output by a mean difference of 4.6 watts and extended time-to-exhaustion by 25.3 seconds . In a 16.1 km time trial, the gains linked to beetroot consumption were equivalent to 48 seconds saved .
4. Repeated Sprint Ability
Beetroot has also been shown to enhance type II muscle fiber contractility, which improves performance in repeated sprint efforts—critical for criteriums and final lead-outs .
The "Elite Cyclist" Caveat
Here is the part most supplement brands won't tell you: Highly trained cyclists often respond less to beetroot than recreational cyclists.
Studies on elite endurance athletes have shown that 6-day nitrate supplementation did not alter VO₂ during submaximal exercise or improve time-trial performance in highly trained cyclists .
This does not mean it doesn't work. It means that elite cyclists already have highly optimized nitric oxide systems. The "margin for improvement" is smaller, so the quality of the product and the timing of the dose matter much more.
For amateur and recreational cyclists, the response is typically much stronger.
The Cycling Dosing Protocol
To get the most out of Stamox, follow this protocol:
Training Sessions
- Dose: 1 tablespoon.
- Timing: 2–3 hours before your ride.
- Why: This allows plasma nitrite levels to peak during your session.
Race Day
- Dose: 2–3 tablespoons.
- Timing: 2.5–3 hours before the start.
- Why: This ensures peak vasodilation and oxygen efficiency for the full duration of the race.
The Non-Negotiable
Avoid antibacterial mouthwash. The oral bacteria on your tongue are required to convert nitrate to nitrite. If you use mouthwash, you kill those bacteria and lose the performance benefit.
Frequently Asked Questions
Can I just drink regular beetroot juice?
You can, but commercial juices vary wildly in nitrate content and are often high in sugar. Stamox is a whole-root extract that delivers the full matrix without the sugar load.
Does beetroot work for short, intense efforts?
Yes. Research shows it enhances type II muscle fiber contractility and improves repeated sprint ability, which is useful for criteriums and interval training.
Will it make my urine pink?
Yes. This is harmless. It is caused by the betalain pigments and is a sign you have consumed real beetroot.
How long until I see results?
The acute effect on oxygen efficiency occurs within 2–3 hours. The cumulative benefits build over 3–7 days of loading.
