About Caffeine Chews
Unlike traditional energy drinks or caffeine pills, this innovative chewable is absorbed through the cheek for quicker delivery into the bloodstream. Each chew delivers a potent 100mg dose of caffeine—about the same as a strong coffee—but with faster, more noticeable results. It’s a convenient and effective alternative to drinks or gels, helping you reach peak performance when it counts most.
Formulated with four types of electrolytes, Caffeine Bullet doesn’t just energise—it supports hydration and endurance too. The combination of caffeine and electrolytes helps mobilise fat stores and delay muscle glycogen depletion, meaning you can go harder for longer. Whether you’re aiming for a race PB, powering through a tough session, or staying alert during a long day, this clever little chew has your back.
Caffeine Bullet also targets mental fatigue by enhancing dopamine function in the brain. This sharpens focus and reduces the perception of effort, making it easier to stay engaged and push through mental or physical walls. The reduced sensation of muscle pain means each session feels more manageable, helping you maintain intensity and motivation right through to the finish.
Endorsed by Dragon’s Den investors, Caffeine Bullet is a smart, no-fuss solution for athletes, gym-goers, and professionals who want a cleaner, faster caffeine source—without the bulk, calories, or sugar of energy drinks.
How does it work
Caffeine Bullet Chew is absorbed through the mouth’s buccal membrane, allowing caffeine to enter the bloodstream more quickly than standard pills or drinks. This rapid delivery system gives you a fast, noticeable lift in energy and focus. The 100mg caffeine dose stimulates the central nervous system, decreasing perceived exertion and reducing muscle pain so you can perform at higher intensities.
At the same time, caffeine encourages the body to use fat as a fuel source, preserving muscle glycogen for later. This is especially beneficial during endurance sports, as it extends the time before fatigue sets in. The inclusion of electrolytes also helps maintain fluid balance, supporting hydration and preventing cramp or early fatigue during intense efforts.
