Enhanced Bioavailability.

Natural and Beneficial Ingredients.

High quality and sustainably sources ingredients: Green Tea, Vitamin B6, and Vitamin B12. These ingredients have been researched for decades to not only enhance your mental and physical performance, but your health and well-being as well. 

Free of the things you hate

Sugar free, gluten free, aspertame free, dairy free, and vegan. No crazy lab produced ingredients that you can't pronounce. 


Many other companies use synthetic caffeine or a caffeine that's extracted from a source. This extracted caffeine is structurally identical to synthetic caffeine and does not provide any additional benefit. Koi Energy gum contains the actual green tea extract so that you can get all the cognitive and health benefits that this ingredient has to offer.
