Detailed Product Description

Clean, Endurance-Optimised Pre-Workout Formula

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.

Opens your vascular system to unleash a rush of oxygen-rich blood straight to your working muscles, helping you glide into a smooth, efficient, natural stride from the start.

• Razor-Sharp Focus Without Jitters: Kills pre-race anxiety, morning brain fog, and exhausting mental friction at the midpoint of a hard workout, when your brain starts screaming at you to slow down. Lock into an unshakable state of pure focus without the jitters.

• Increased Ventilatory Threshold: Promotes enhanced oxygen uptake and blood flow so you can sustain higher intensities for longer and hold your pace without burning out.

• Gut-Friendly Performance: Prime your body's energy pathways with absolute confidence, keeping your stomach feeling light, settled, and cooperative.

How to Use / Directions

• Serving Size: Take 3 plant-based capsules 30 minutes before your training session.

• Pro Tip: For optimal delivery, ingest with one serving of beHydrate Performance Electrolyte Drink.

The Evidence-Based Science Behind the Timing:

1. Synchronised Absorption: Taking capsules 30 minutes pre-run aligns perfectly with the metabolic absorption rates of both caffeine anhydrous and dietary nitrates, ensuring peak plasma concentrations hit your bloodstream right as you start.

2. Nitric Oxide Pathways & Vasodilation: Converts plant-sourced nitrates into nitrite and ultimately Nitric Oxide. This gaseous molecule relaxes and dilates blood vessels, lowering the oxygen cost of exercise and reducing early-run friction.

3. The Blood Volume Synergy (Pairing with beHydrate): Vasodilation expands your vascular network. Pairing beEnergy with electrolytes ensures optimal blood plasma volume, allowing your cardiovascular system to rapidly transport oxygen and nutrients to working muscles.
