4% OffFree Shipping

Why We Love It

Fast, direct caffeine boost.
Reduces tiredness, increases stamina.
Clean, jitter-free energy.

Main Highlights

EXTREMELY FAST CAFFEINE BOOST – Because you chew Caffeine Bullets, caffeine is absorbed through membranes in the mouth directly into your bloodstream, bypassing your stomach, giving you a caffeine kick in as little as 5 minutes. When you’re tiring in a race or struggling at the gym that could be the difference between winning and losing or setting a new Personal Best.
CAFFEINE REDUCES TIREDNESS AND FATIGUE – the perfect sports nutrition for breaking your personal best or as a caffeine kick for a pre workout boost so you can train harder for longer. Ideal for running, cycling, swimming, triathlon. No matter what sport caffeine fuels your performance for better results.
INCREASED STAMINA – Caffeine mobilises your fat stores as a fuel source instead of depleting muscle glycogen stores which can be saved for increased endurance. Whether you’re running a marathon, cycling a sportive or a body builder undertaking an intense session in the gym caffeine supplements your carbs intake to ensure that you don’t bonk or hit the hall. Become an energy monster with a caffeine shot like no other.
INCREASE ALERTNESS – when we tire we lose concentration. Caffeine blocks receptors in the brain protecting you from the effects of tiredness, giving you a caffeine high which increases your alertness and allows you to stay focused for longer and stay awake when driving, working or pulling an all-nighter.
NO JITTERS - NO BULL - a lot of caffeine products give you tingly rage and fill you with unhealthy nasties, we don’t. At less than 35kcal each chew fuels you with clean energy that feels natural and lasts longer for better performance.
