Energy Powder (Yuzu Flavor)

Most pre-workouts deliver caffeine without control. This natural pre workout for runners pairs natural caffeine from green tea with L-theanine for focused, sustained output across a full training session, with no jitters and no crash in the back half.

Caffeine is the most consistently documented ergogenic aid in endurance sport, with research showing reduced perceived exertion and improved time to exhaustion. L-theanine moderates caffeine's stimulant response by promoting alpha-wave brain activity and reducing heart rate elevation, preserving alertness without the energy spike that drops runners at mile 14. The formula also includes four electrolytes (calcium, magnesium, sodium, and potassium) and a full B-vitamin complex, supporting hydration and the metabolic pathways that convert macronutrients into ATP during sustained running effort.*

For the runner who has felt caffeine work against them: the tempo run that turned ragged from jitters, the long effort where the pre-workout spike became a deficit two hours in. Also relevant for runners who want light electrolyte support without a separate hydration product on shorter quality sessions.

FAQ

Q: Does caffeine actually improve running performance, or does it just reduce how hard the effort feels?

Both, and the distinction matters for training application. Caffeine blocks adenosine receptors in the brain, reducing perceived exertion during sustained effort and delaying fatigue onset. It also increases circulating adrenaline, supporting power output in high-intensity intervals. In distance running, the primary benefit is the reduction in perceived effort: research consistently shows faster finishing times at the same physiological cost. It is the most evidence-backed legal ergogenic aid in endurance sport.

Q: When should a runner take this before a session?

30 to 45 minutes before effort is the target window for peak caffeine absorption. On race day, extend to 45 to 60 minutes to account for gastric emptying that slows under pre-race stress. Start with 1 scoop and assess tolerance before increasing. Do not use within 5 to 6 hours of sleep: caffeine's half-life of approximately 5 to 6 hours will impair recovery quality, and recovery is where training adaptation occurs.

Q: Is this suited to long runs and marathon training, or only short sessions?

The caffeine-plus-L-theanine combination is particularly well-suited to long efforts. L-theanine smooths the stimulant curve, which is relevant for sessions of 2 hours or more where a caffeine spike at mile 5 becomes an energy deficit at mile 14. The electrolyte content provides supplementary hydration support during effort.

Q: How is natural caffeine from green tea different from synthetic caffeine?

Both deliver the same molecule with the same mechanism of action at the adenosine receptor. Natural caffeine from green tea is bound to plant compounds (catechins and tannins) that modestly slow gastric absorption, producing a more gradual onset compared to anhydrous caffeine. For distance runners, that absorption profile aligns better with sustained-effort sessions than the faster spike of anhydrous caffeine.
