Beets, Cherries, and Broccoli: Nature’s Performance Enhancers for Endurance Athletes

In the world of endurance sports, athletes and coaches are constantly searching for legal, evidence-based edges to improve performance, accelerate recovery, and support consistent training. While synthetic supplements often dominate discussions, whole-food-derived options like beetroot (beets), tart cherries, and broccoli sprouts have gained significant traction. These “super veggies” provide bioactive compounds, nitrates, polyphenols/anthocyanins, and isothiocyanates/sulforaphane, that target distinct physiological pathways.

This article explores the science behind these three powerhouses, Cherries, Broccoli, and Beets. We’ll examine their mechanisms, review key research findings (including meta-analyses), discuss commercial products, and consider how they might complement each other in an athlete’s routine. The goal is a balanced, evidence-informed overview rather than hype.

1. Beets: The Nitric Oxide and Blood Flow Booster

Beetroot juice and concentrated beet shots are among the most researched natural ergogenics in sports nutrition. The star compound is dietary nitrate (NO₃⁻), which the body converts to nitrite and then nitric oxide (NO). NO is a potent vasodilator that enhances blood flow, oxygen delivery to muscles, and mitochondrial efficiency.

Key Mechanisms:

• Reduces the oxygen cost of submaximal exercise (improved economy).

• Enhances tolerance to high-intensity efforts.

• May lower blood pressure and support cardiovascular health as a bonus.

Research Highlights: Multiple meta-analyses support benefits, particularly for time-to-exhaustion (TTE) tasks, power output, and endurance performance in moderately trained individuals. A 2017 systematic review found beetroot juice supplementation improved cardiorespiratory endurance. More recent analyses (e.g., 2025) confirm small but significant improvements in VO₂max, muscle strength (especially in pros), lactate tolerance, and time-to-exhaustion, with doses around 500–1000 mg nitrates (8–16 mmol) showing optimal effects. Acute dosing 2–3 hours pre-exercise or chronic loading (≥3 days) both work, though effects can be smaller or inconsistent in highly elite athletes (VO₂peak >65 ml/kg/min).

A classic study showed whole beetroot consumption improved 5-km running performance, with faster velocities in the later stages and lower perceived exertion.

Practical Notes and Products:

• Avoid mouthwash on dosing days, as oral bacteria are key for nitrate reduction.

• Products like Amacx Beet Shot deliver a high, convenient 500 mg nitrate dose in a 60 ml shot. Informed-Sport certified options ensure quality and safety.

Beets shine for “delivery” - getting more oxygen to the engine efficiently.

2. Tart Cherries: The Recovery and Anti-Inflammatory Specialist

Tart (Montmorency) cherries are packed with anthocyanins and other polyphenols that provide strong antioxidant and anti-inflammatory effects. These help combat exercise-induced muscle damage (EIMD), oxidative stress, and inflammation without the downsides of excessive NSAID use.

Key Mechanisms:

• Scavenge free radicals and reduce markers like CRP (C-reactive protein).

• Support faster strength recovery and reduced soreness.

• May improve sleep via natural melatonin content.

• Potential low-GI carbohydrate support and enhanced blood flow.

Research Highlights: A 2020 meta-analysis of 10 studies concluded that tart cherry concentrate significantly improved endurance exercise performance (e.g., time to completion or TTE in cycling/running). Studies on runners and other athletes show reduced pain, faster recovery of maximal voluntary contraction (MVC), and attenuated inflammation post-marathon or damaging exercise.

A 2026 meta-analysis on EIMD recovery found significant improvements in MVC at various time points post-exercise, with reductions in CRP. Benefits are often seen with 7+ days of supplementation around hard efforts or races. Results for DOMS (delayed onset muscle soreness) and some performance metrics are more mixed, highlighting individual variability and the need for more high-quality trials.

Products: Concentrated juices, powders, or shots (sometimes combined with beets, like Beet It Regen Cherry+). Many athletes use them post-training or in the evening for recovery and sleep support.

Cherries excel at “protection and repair” - blunting damage and speeding rebound.

3. Broccoli Sprouts: The Cellular Defense and Adaptation Activator

Broccoli sprouts are exceptionally rich in glucoraphanin, which converts to sulforaphane and other isothiocyanates (ITCs). These activate the Nrf2 pathway, the body’s master regulator of antioxidant defenses, detoxification, and cellular stress response. This is particularly relevant for heavy training blocks.

Key Mechanisms:

• Upregulates endogenous antioxidants, reducing oxidative stress.

• May lower blood lactate accumulation.

• Supports mitochondrial biogenesis and training adaptations.

• Anti-inflammatory effects and better recovery.

Research Highlights: A 2023 randomized trial (Flockhart/Larsen et al.) using glucosinolate-rich broccoli sprouts during a high-intensity training week reduced oxidative stress, lowered lactate, improved glucose regulation, and extended time to exhaustion by ~12%. Muscle biopsies supported Nrf2 activation.

Acute dosing studies (e.g., 3 hours pre-exercise) also showed lactate-lowering effects. In vitro work suggests enhanced mitochondrial adaptations. While research is newer and some studies are small or industry-linked, the mechanistic plausibility is strong, and elite athletes (e.g., Mads Pedersen) have adopted it. A 2026 study on broccoli powder did not find acute benefits in one session for untrained men, underscoring the value of consistent use during training loads rather than isolated efforts.

Products: Nomio’s 60 ml shot condenses the equivalent of ~6.5 lbs (or ~2.5–3 kg in some descriptions) of broccoli sprouts into a convenient, lemon-flavored format. It’s positioned for pre-hard-session or bedtime use in heavy blocks.

Broccoli provides “defense and adaptation” - protecting cells and amplifying training gains.

Stacking Them: Complementary Pathways for a Faster Athlete

These aren’t competitors, they’re teammates:

• Beets: Oxygen delivery and efficiency (nitric oxide pathway).

• Cherries: Inflammation control and soreness reduction (polyphenols).

• Broccoli: Oxidative stress management and cellular resilience (Nrf2/ITCs).

They target overlapping but distinct aspects of performance and recovery with minimal overlap in mechanisms, making stacking logical. Many products and bundles already combine beets and cherries; adding broccoli shots fits naturally for comprehensive support.

Other Relevant Considerations:

• Individual Variability: Trained elites may see smaller effects from nitrates. Genetics (e.g., nitrate reductase efficiency), diet, and training status matter.

• Practical Integration: Timing is key—beets 2–3h pre, broccoli similarly or nightly, cherries around sessions/recovery windows. Whole-food sources are ideal but shots offer convenience and standardization.

• Safety and Quality: Choose tested products (e.g., Informed-Sport). High nitrate intake is generally safe; consult professionals for personalized advice.

• Broader Context: These fit into a holistic approach with proper fueling, sleep, and periodization. They’re not magic but can support marginal gains.

• Emerging Areas: Synergies with other aids (e.g., caffeine), long-term adaptation studies, and effects in different sports/environments warrant more research.

Conclusion: Veggies as Serious Performance Tools

The science, while not unanimous or universally large in effect size, is compelling. Beetroot nitrates have the strongest evidence base for acute performance, tart cherries for recovery, and broccoli-derived ITCs for training resilience and lactate management. Professional references like those from Nutrients, Sports Medicine, and specific trials (e.g., Flockhart 2023, Gao meta-analyses) lend credibility beyond anecdotal success stories from pros.

For endurance athletes, incorporating these, whether via whole foods, juices, or convenient shots like Amacx, Nomio, or tart cherry concentrates, offers a natural, food-first strategy aligned with “real” nutrition. As Matt from The Feed puts it, "veggies can help you go faster." Experiment responsibly, track your responses, and combine with evidence-based fundamentals for the best results.
