G FUEL Drink Formula is a brand of caffeinated drink mix sold by Gamma Labs, based in West Babylon, New York. It is marketed as a supplement for gaming that boosts focus and reaction time and claims that its advantage over conventional canned energy drinks is that its lack of sugar prevents the fatigue (or "crash" as the company refers to it) that comes when it wears off.


G FUEL originally released as a caffeinated powder intended to be mixed with water and has expanded its line of products over time to include a non-caffeinated version of the powder, a carbonated version in a can, a powdered hydration formula, and a pop rock like version in a tube.[


On August 26, 2020, G FUEL announced it made the Inc. 5000 list, which ranks the 5,000 fastest-growing private companies in the United States, for the fifth consecutive year. Previously, G FUEL made the Inc. 5000 list in 2016, 2017, 2018, and 2019.
