G FUEL is a 100% clean, natural and healthier alternative to most energy drinks that contain sugar. While many energy drinks contain large amounts of unknown chemicals, with G FUEL you know exactly what you’re drinking, as you mix the powder with your own water. All formulas are designed with a strong focus on quality and high customer demands for increased energy, attention, and concentration, without the use of toxic chemicals or added sugar.
Energy Complex
Caffeine is a natural stimulant consumed worldwide. Its primary benefit is the stimulation of cognitive functions – essentially giving your mind a "boost" when you need it most.
Full of Vitamins
G FUEL formula contains a great and balanced amount of vitamins C + E + B12 + B6 in an excellent ratio. B vitamins help maintain the blood and nervous system in great condition so you can perform at 100%.
No SUGAR
Unlike "competitors" that rely on loads of sugar to give you a fake sense of energy, G FUEL does not – which means no crash.
Full of Antioxidants
The right balance of antioxidants that work together with the vitamin complex to support healthy cell production.
100% FOCUS
A solid selection of amino acids gives you a unique advantage. In addition to taurine, you’ll also find L-Tyrosine, which may support energy, motivation, focus, mental clarity, and overall mood quality.
Value Packaging
By purchasing a full G FUEL tub, you save both time and money. Thanks to the simple packaging, you get 40–50 servings of delicious G FUEL energy drink.
How to prepare your drink
We recommend filling your shaker to the 400 ml mark (measurement lines are marked on the sides of the shaker in both ml and fluid ounces), which is the recommended amount of water for one serving.
The scoop inside the tub is divided into two parts. The top cone-shaped piece can be easily removed, as it is not part of a single serving and is used for easier pouring into bottles with a narrow neck, for example when you're on the go and don’t have your BRAINFUEL Shaker with you.
Once you pour the scoop into the shaker, make sure it is tightly screwed and the lid is properly closed. We recommend mixing the drink thoroughly with fast up-and-down movements for at least 1 minute.
Warning: Keep out of reach of children. Contains caffeine. Not recommended for children, pregnant or breastfeeding women, individuals sensitive to caffeine, or those with high blood pressure or cardiovascular conditions. Do not mix with alcohol. Do not exceed the recommended daily dose (max. 3 servings per day).
