About Brain Bullet Focus Chews

The chewable format offers a convenient alternative to coffee, energy drinks or capsules. Simply chew for 30 seconds to release the formula, making Brain Bullets easy to use at your desk, while studying, before a demanding task or during a long shift.

Brain Bullets are available in two flavours. Mental Mint Matcha combines refreshing mint with the earthy taste of matcha green tea, while CaraMENTAL Frappe delivers a smooth blend of caramel and vanilla flavours.

With just 26 calories per chew and a low-sugar formula, Brain Bullets provide a simple way to support productivity when you need to feel more switched on. The combination of caffeine and L-Theanine is designed to improve alertness while helping to reduce the jitters commonly associated with caffeine alone.

How does it work

Each Brain Bullet combines 80mg of caffeine with 160mg of L-Theanine. Caffeine helps increase alertness and reduce feelings of tiredness, while L-Theanine is included to support a calmer and more focused experience.

The chewable format allows the ingredients to be released quickly as you chew. This makes Brain Bullets a practical option when you need support before a mentally demanding task, without the preparation or volume of a caffeinated drink.

About Performance Bullet

Performance Bullet was founded by David Hellard, a marathon and ultra-running champion. Each bullet blends caffeine with four types of electrolytes to increase endurance and improve athletic performance. And because it's chewed the caffeine is absorbed through your cheeks directly into the bloodstream for a concentrated caffeine hit far faster than energy gels, drinks or caffeine pills, allowing you to train harder and race faster.
