Safe and Legal in Sport

Clean, Endurance-Optimised Formulation

Research-Aligned Performance Dose.

  • What problem does this solve? It eliminates that agonising, heavy-legged sluggishness during the opening miles of your run, where your chest feels tight, your lungs burn for air, and you feel like you are fighting to hit your baseline training pace.

  • So you can... Open up your vascular system to unleash a rush of oxygen-rich blood straight to your working muscles, allowing you to glide into a smooth, efficient, and completely natural stride right from the start.

How to use

Take 3 plant-based capsules 30 minutes before your training session.

For optimal delivery, ingest with one serving of beHydrate Performance Electrolyte Drink.

The Evidence-Based Science Behind the Timing:

  • Synchronised Absorption: Taking the capsules 30 minutes pre-run aligns perfectly with the metabolic absorption rates of both caffeine anhydrous and dietary nitrates. This ensures peak plasma concentrations hit your bloodstream exactly as you begin your workout.

  • Nitric Oxide Pathways & Vasodilation: The 30-minute window allows your body to begin converting plant-sourced nitrates into nitrite and, ultimately, into Nitric Oxide. This gaseous molecule relaxes and dilates your blood vessels, lowering the oxygen cost of exercise and reducing early-run friction.

  • The Blood Volume Synergy (Why Pair with beHydrate?): Nitric oxide-induced vasodilation expands your vascular network. To maximise this effect, your body requires optimal blood plasma volume. Pairing beEnergy with the full-spectrum electrolytes in beHydrate ensures your cardiovascular system has the fluid balance it needs to rapidly transport oxygen and nutrients directly to your working muscles.

Ingredients

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

Oxygenate Your Muscles

Optimise your blood flow.

  • Reset your pacing boundaries, making it vital to optimise your blood flow before your next hard workout.

Fast Shipping

Rapid Dispatch.

  • Because we source our high-dose, concentrated red spinach extract in strict small-batch runs to guarantee maximum nitrate potency, ordering today ensures you secure your supply before peak-season endurance demand clears our current inventory.

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.
