Alana and Juliet Barratt launched Grenade UK in 2010 with the goal of becoming Britain's most iconic weight-loss brand. Grenade's flagship product, the Thermo Detonator®, became so popular that customers started requesting more and more workout supplements. In 2012, Grenade UK introduced a line of protein powders and pre-workout formulas to help fitness enthusiasts make further gains in the gym. Three years after that, Grenade UK's Carb Killa® protein bars hit the market. Since the debut of their protein bars, Grenade UK has put most of their research efforts into creating energy drinks, electrolyte mixes, and supplements for cognitive enhancement.
