Every Beet Supplement Was Built for Marathoners. Here Is What Sprinters Actually Need.
The science for dietary nitrate is strongest for explosive athletes. Every brand selling beet supplements built theirs for the wrong sport. Nobody built one for you — until now.

Go search every beetroot supplement on the market.
Beet It Sport: built for marathon runners, endorsed by distance cyclists. SuperBeets: cardiovascular health for middle-aged adults. BeetElite: "stamina and endurance." Pre Lab Pro: contains caffeine — which, as you are about to learn, cancels the entire mechanism.
Not one of them uses the words sprint, acceleration, fast-twitch, or explosive.
"I searched every beetroot supplement on the market for sprinters. I found exactly zero." Finn Reiser, Team USA Sprinter
Here is the irony that every one of those companies is missing: the peer-reviewed science for dietary nitrate supplementation is strongest for sprint and power athletes — not endurance athletes. The mechanism preferentially targets the exact muscle fibers that make you a sprinter.
The marathon brands claimed a supplement that was never theirs to claim. Nobody planted a flag for the sprinter. This is that flag.
What Happens to Your Fast-Twitch Fibers After 60 Meters
You have a fast takeoff. Your drive phase is clean. But around 60 to 80 meters, something shifts. Legs go heavy. Form falls apart. Competitors come through. You cross the line knowing you had more in you.
"I have a fast take off, but once I hit 60m or so it starts getting awkward. I never broke 28.00. But I can take off with guys that run 25-26. I always lose them around 60-80m." LetsRun.com, "How do you run the last part of a 200m?"
"Sprinting around the final curve, I felt my legs turn into cement blocks and my arms turn to rubber. One runner passed me, then another. I knew I was finished." Hurdles First Magazine
This is nitric oxide depletion during fast-twitch muscle fatigue. After your acceleration phase, nitric oxide — which dilates blood vessels and shuttles oxygen to working muscle — is depleting in the exact fibers generating your speed. The result is what every sprinter calls "tying up."
Here is the critical scientific distinction that the endurance brands ignore: nitric oxide preferentially targets type II fast-twitch muscle fibers. Neuronal nitric oxide synthase (nNOS) is predominantly expressed in type II fibers. The low oxygen tension surrounding fast-twitch fibers creates optimal conditions for nitrite-to-NO conversion.
This is not the physiology of a marathoner. This is your physiology.

Increase in maximal knee extensor velocity with dietary nitrate (Coggan et al., 2015)
The Science the Marathon Brands Are Ignoring
Thompson 2016
5 days of beetroot juice improved 20m sprint time by 1.2% and 10m sprint time by 1.6% in team-sport athletes. That translates to 0.04-0.06 seconds in a 100m race — enough to change placements at competitive levels.
Rimer 2016
6% increase in maximal cycling power after acute beetroot juice. Large effect size (d=1.21).
Alsharif 2023
Meta-analysis of 27 studies: greatest performance benefits occur during 15-30 second maximal efforts. That is a 100m. That is a 200m. That is your race.
Sports Med 2025
Umbrella review of 20 systematic reviews confirmed significant improvements in peak power output (SMD=0.25) and a large effect on time to reach peak power (SMD=-0.76). Minimum effective dose: 6 mmol/day with chronic (3+ days) loading.
Coggan 2015
11% increase in maximal knee extensor velocity and 6% increase in maximal muscle power — effects on contractile speed, not endurance.
The Thing Your Pre-Workout Is Doing to Your Beet Supplement
Critical Interaction
Caffeine consumption negates the nitrate-to-nitric oxide conversion pathway. Your oral bacteria convert dietary nitrate to nitrite — and then to NO in muscle tissue. Caffeine disrupts this cascade entirely. If you are stacking a stim pre-workout with a beet product, you are paying for beet and getting zero benefit from it.
Sprint coach Carl Valle noted: "The use of a beetroot product is negated when consumed with caffeine." This is supported by published research and represents one of the most commonly wasted supplement dollars in track and field.
NitroSprint is stimulant-free by design — not because we could not add caffeine, but because stimulants cancel the mechanism that makes beetroot work. This is a feature, not a limitation.
Add the mouthwash warning: antibacterial mouthwash kills the oral bacteria required for the nitrate-to-nitrite conversion. Skip it on training and meet days.

Messaging themes across every competitor: "nitric oxide production," "blood flow," "endurance and stamina," "heart health." Entirely absent from the market: explosive power, acceleration, fast-twitch activation, block-to-finish. The world of beetroot supplements was claimed by marathoners.

NitroSprint: Built for the Type II Athlete
FR
Finn Reiser — Team USA Sprinter, RMS Nutrition Founder
I built NitroSprint because nobody else was going to. I am a Team USA sprinter. I competed in the 100m and 200m. The science told me beet supplementation had its strongest rationale for what I do — and zero brands were speaking my language. NitroSprint is stimulant-free because you already have enough adrenaline when you step behind the blocks.
⚡
Fast-Twitch Specific
Dietary nitrate preferentially increases blood flow to type II muscle fibers. The endurance brands built for their audience. This was built for yours.
🚫
Stimulant-Free by Design
Caffeine cancels the nitrate-to-NO conversion pathway. NitroSprint contains zero stimulants so the mechanism works the way the research shows.
📋
Transparent Dosing
Standardized nitrate content per serving, fully disclosed. Not hidden behind a proprietary blend like SuperBeets — which does not even reveal its active ingredient quantity.
🏃
NCAA and WADA Safe
WADA does not ban dietary nitrates. NCAA does not ban beetroot. Zero stimulants. Zero undisclosed substances. The performance support you can take to conference championships without risking your eligibility.
The Protocol
NitroSprint Competition Protocol
1
Timing: Take 2-3 hours before competition. Peak plasma nitrite levels align with this window.
2
No caffeine conflict: Do not stack with a stimulant pre-workout. They cancel each other.
3
No antibacterial mouthwash: Skip it on training and competition days. It kills the oral bacteria needed for nitrate-to-nitrite conversion.
4
Chronic loading for meet week: Start NitroSprint 3 days before your meet. Chronic loading produces more consistent results than a single acute dose. Peak day is day 3-5.
Questions Sprinters Ask
"Beet root juice only works if you suck at running."
This is a common objection on running forums, and it contains a partial truth: effects are less consistent in elite-trained athletes with very high VO2max (above 65 mL/kg/min). The evidence is strongest for competitive but not world-class athletes — which describes the vast majority of the sprint community. Alsharif 2023 confirms greatest benefits in 15-30 second efforts regardless of training status.
Is this legal for my sport?
Yes. WADA does not ban dietary nitrates. The NCAA does not ban beetroot. NitroSprint contains zero stimulants and zero substances on any prohibited list. A 2025 study found 45 synthetic substances in nootropic supplements with unclear WADA compliance — NitroSprint contains none of them. Organic beetroot concentrate, standardized nitrate content, fully disclosed.
SuperBeets is cheaper. Why choose NitroSprint?
SuperBeets targets middle-aged consumers worried about blood pressure. It does not disclose its nitrate content, which makes it impossible to know if you are reaching the minimum effective dose (6 mmol/day). NitroSprint specifies standardized nitrate content, was built for explosive athletes, and positions for the fast-twitch fiber mechanism — the category SuperBeets never claims.
I tried beet juice before and felt nothing.
Three likely reasons: (1) timing — you need 2-3 hours for peak plasma levels, most athletes take it too close to race time; (2) caffeine conflict — if you had any stimulant that day, the pathway was cancelled; (3) mouthwash — antibacterial mouthwash kills the oral bacteria required for conversion. If all three factors are controlled and you still see no benefit, you may be in the minority of non-responders, which the research acknowledges exists.

"NitroSprint hit different in the third 100 of my 400. That's when most people die. I kept my mechanics together through the backstretch in a way I haven't before. PRed by eight-tenths."
— Anthony L. | NCAA 400m, CA
★★★★★
"My coach told me I looked like a different runner in the home stretch. That's because I was. The muscle fatigue that used to hit me at 300m was completely different on NitroSprint."
— Simone H. | High School Sprinter, FL
★★★★★
"I've been supplementing beet root for years — NitroSprint is the first product that actually combines the right compounds at the right doses for sprinters specifically. Not generic endurance athletes. Sprinters."
