Sustain Gum by Caffeine Bullet (12)


Performance Enhancing, Sustainable, Plastic Free Caffeine Chewing Gum

Sustain Gum—the first ever 100% Biodegradable, Plastic Free Caffeine Chewing Gum. With 50 mg of caffeine per piece, Sustain Gum is plant-based, and decomposes like fruit, allowing you to sustain both yourself and the Earth.

Many caffeine products give you the jitters packed with unhealthy nasties and most other gums are made from plastic. Our biodegradable caffeine gum is Sugar Free - No filler, No Bull. We use xylitol a plant-based sweetener and natural flavourings of peppermint and menthol for a tasty, refreshingly chew.

At less than 5 calories per piece, it fuels you with clean energy that feels natural and lasts longer for better performance.  12 Pieces Per Pack


Sustain Gum was designed with your performance in mind, but the price of success shouldn’t be the Earth. That's why we use a natural gum base made from plants, making our caffeine gum both biodegradable and environmentally friendly.

Because you chew Sustain Chewing Gum, the caffeine is absorbed through membranes in the mouth directly into your bloodstream, bypassing your stomach,so you only need to chew for5-10 minutes(dispose of the gum after 10 mins!) to get the caffeine kick you need to maximise your performance. 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.


Sustain Gum has benefited many, from ultrarunners and elite level athletes to gym enthusiasts and shift workers. We're thrilled about the impact we're making on people's lives (and without harming the planet!).
