Safe and Legal

Clean, Endurance-Optimised Formulation

The Problem: Heavy legs, tight breathing, and a sluggish first few miles.

The Solution: Caffeine and red spinach extract, a natural source of nitrates, in one easy dose.

What’s In It For You:

🫁 Easier Breathing: Supports blood flow so more oxygen reaches your working muscles.
⚡ Sharper Focus: Caffeine helps you feel alert and ready from the first step.
🏃 Smoother Miles: Running feels less like a struggle, so you can settle into your pace sooner.

How to use

Take 3 capsules 30 minutes before your run.

The Science of Perfect Timing

⏰ Peak Workout SynchronizationTake beEnergy 30 minutes pre-run. This precise window ensures caffeine and dietary nitrates flood your bloodstream right as your workout begins, not halfway through.

🚀 Drop Early-Run FrictionThat 30-minute window gives your body time to convert plant nitrates into Nitric Oxide, widening blood vessels and lowering the "oxygen cost" so early miles feel noticeably lighter.

💧 The beHydrate Synergy (Blood Volume)

Widening your blood vessels is only half the battle; you need enough fluid volume to fill them.

⚡ Plasma Optimization: Pairing beEnergy capsules with the full-spectrum electrolytes in beHydrate optimizes your blood plasma volume.

🫁 Maximum Oxygen Delivery: This combination ensures your cardiovascular system has the fluid balance required to rocket oxygen and nutrients straight to working muscles.

Ingredients

2,000mg of dietary nitrates from Red Spinach Extract 50:1 (equivalent of 10,000mg)
235mg of Caffeine Anhydrous

The Science: Why Red Spinach Destroys Beet Juice

Upgraded Nitric Oxide: Red Spinach vs. Beetroot

Forget messy beet juice shots and sugary pre-workout powders. While beetroot helped pioneer endurance science, Red Spinach Extract is lightyears ahead for runners.

🧬 4x More Nitrates Per Gram: Gives you maximum vascular expansion without forcing you to chug heavy, sugary liquids before a run.
🫄 Zero Stomach Sloshing: No thick plant sludge or digestive distress—just clean, rapidly absorbed nitrates that keep your gut light and calm.
⚡ Instant Vasodilation: Converts to nitric oxide faster than beet juice, opening up your blood vessels for an immediate surge of oxygenated blood from mile one.

Southward, Rutherfurd-Markwick and Ali, 2018

Taking over 200mg of caffeine before your run can measurably boost endurance, helping you go further, hold your pace longer, and perform at a higher level when it counts.

Guest et al., 2021

Multiple studies have demonstrated that caffeine-powered pre-workouts help you push harder and last longer, so you can power through tough efforts and still have the energy to finish strong.

Wen et al., 2025

Evidence has shown that red spinach delivers a powerful nitric oxide boost to improve blood flow, helping you run further, feel stronger, and maintain your pace with less effort.

Moore et al., 2017

Red spinach helps raise your ventilatory threshold, so you can sustain higher intensities for longer and hold your pace without burning out.

Frequently Asked Questions

Got questions? We’ve got answers!

Why does beEnergy contain caffeine?

Caffeine has demonstrated its effectivness at reducing fatigue, time to exhuastion, muscle performance, agility and reducing muscle pain. Put simply, it helps you perform stronger.

Is red spinach extract more potent than beet?

Red spinach extract has a very high concentration of natural nitrates when compared to beet powders or juices.

How long before I see results?

Take beEnergy approximately 45-30 minutes before training or racing to feel the benefits.

Is it safe to take every day?

beEnergy is safe to use every day, but be aware of the high caffeine content. If you are sensitive to caffeine, you could spread the capsules out over a longer period of time.

How much caffeine is in beEnergy?

We have included 235mg of caffeine per dose. One dose consists of 3 capsules.

Why have you included red spinach extract?

Red spinach extract is extremely rich in natural nitrates, which are converted into nitrites and then nitric oxide in the body.

What's so good about red spinach extract?

Red spinach extrcat found in beEnergy has a wealth of benefits for the athlete. These include improved cardiovascular function that leads to better athletic performance, but is also rich in essential nutrients that contribute to muscle repair and growth. It is also rich in antioxidants to fight free radical damage and inflammation.

Other products contain more ingredients, so why doesn't yours?

We align our products with the recommendations issued by the American College of Sports Medicine. They state that nitrates and caffeine improve performance, so that's what we've stuck with.

Isn't a Redbull or Monster better?

Those are fizzy (carbonated) caffeinated drinks. They do not improve nitric oxide production and are not ideal to drink before running due to the gassy effects they can have.
