SUGGESTED USE

Chew one piece within 15 minutes before initiating exercise. Alternatively, for longer sessions, one piece can be chewed during exercise 15 minutes before the desired performance effect.

Up to two pieces can be taken at the same time. Do not take more than four pieces in a day. 

RECOGNIZED BY SCIENCE

Caffeine is scientifically recognized for helping to increase alertness and reduce feelings of fatigue. In a convenient chewing gum format, caffeine can be absorbed quickly through the mouth, supporting a faster onset compared to traditional sources. This makes caffeine gum a practical, fast-acting option when you want a simple and efficient way to feel more alert. 

Cognitive and Physical Performance

Backed by decades of research, caffeine stands out as one of the most trusted performance ingredients in sports1, helping athletes feel sharper, stronger, and more ready to perform.

Cognitive and Physical Performance

HOW DOES CAFFEINE HELP?


From endurance sessions and strength training to power, agility, and reaction-time demands, caffeine can enhance performance across almost all types of sport and exercise2,3,4,5,6,7,8. 


Caffeine works by blocking adenosine, a compound associated with feelings of fatigue, helping you feel more alert, focused, and switched on when it matters most9. This supports sharper concentration, quicker reactions, and a reduced perception of effort during exercise. Caffeine may also help the body utilize more fat during exercise10 and enhance muscle glycogen replenishment after exercise11.

A Targeted Caffeine Hit

How you take your caffeine matters. Traditional options like tablets or capsules, shots, drinks, or gels all work, but they take time. Typically, you will not feel the effects for 20 – 30 minutes, with peak levels reached around 60 minutes, because caffeine must pass through the digestive system and liver before it can act on the central nervous system.

A Targeted Caffeine Hit

WHY GUM?


Caffeine gum changes the game. When chewed, caffeine is absorbed directly through the mouth and esophagus, with only a small amount passing through the gut. Research shows that around 85% of the caffeine in gum can be absorbed within just 5-15 minutes12, meaning it reaches the bloodstream and its key targets in the brain, significantly faster than capsules or drinks.

This faster delivery supports quicker increases in alertness, focus, motivation, and reaction speed, while helping reduce the perception of effort and discomfort during exercise. The result? Performance benefits13 you can feel sooner and exactly when you need it, shown across a wide range of sports, from improving physical performance in team sports such as football14 and rugby15 to enhancing endurance performance in running16 and cycling17. 

Caffeine gum offers a smarter, more flexible way to support performance, providing rapid absorption, faster onset, and a lighter feel that may be easier on the stomach. It’s a modern, practical way for athletes to consume caffeine, offering faster availability, greater timing control, and a more targeted approach to supporting performance.
