Energy
Steady energy, no sharp fall-off.
80 mg natural caffeine. A real but controlled dose, with no sugar spike to crash from. The energy you start with is the energy you finish with.

Natural caffeine plus L-theanine, L-tyrosine and OSMØ® electrolytes. The focus and lift of a coffee, but it hydrates and holds steady instead of spiking and crashing.
Built by Olympic Champion Tom Digby, who came off maltodextrin himself over gut-health concerns, alongside sports scientists and real athlete analysis.
The only Informed Sport Cluster Dextrin® gel on the market. Tested for banned substances, trusted by tested athletes.
Every stick pairs natural caffeine with L-theanine: caffeine for clean, lasting energy, L-theanine to smooth its edge into calm, sharp focus. No jitters, no crash. Tyrosine sharpens mental focus under pressure, taurine supports endurance and recovery, and our OSMØ® electrolytes keep you hydrated throughout. We chose this exact pairing because it performs like a strong coffee or an energy drink, without the sugar, stimulants or additives that tax you over the years. 80 mg natural caffeine, 200 mg L-theanine.
What the Clean Energy Stick does for you
Energy
80 mg natural caffeine. A real but controlled dose, with no sugar spike to crash from. The energy you start with is the energy you finish with.
Focus
200 mg L-theanine smooths caffeine's edge for calm concentration. Research shows up to a 60% drop in perceived stress versus caffeine alone.
Hydration
OSMØ® electrolytes offset caffeine's dehydrating effect; taurine, magnesium and B-vitamins support endurance and recovery. Energy that works with your body, not just your alertness.
COMMON PROBLEMS
Coffee before a key session, then flat and foggy by the end
Energy drinks work, but not the sugar and additives that come with them
You read the label, and you don't recognise half of what's on it
You think about what years of this habit are doing to you, not just today's effort
“You won't trade your long-term health for a short-term edge. Neither will we.”

"A career told me energy meant sugar and a synthetic hit. It doesn't have to."

Why Tom built the Clean Energy Stick around clean, controlled caffeine — the lift of a coffee, without the sugar, the crash or the long-term cost.

Real Athletes. Real results.
"I cut ultra-processed food everywhere else but still relied on coffee before long runs. Kick gives me the same lift with no sugar and no crash. And I actually trust what's in it."
"I've done the sweat tests and I read every label. First caffeine product that fits how I think about training and long-term health at the same time."
"Steady focus across a four-hour ride, no spike, no drop and it hydrates while it does it. Won't go back to gas-station energy drinks."
"I'm careful what I recommend to the athletes I coach. Clean caffeine that also brings electrolytes and theanine? That one's easy."
