Grenade is a UK-born sports nutrition and snack brand that burst onto the scene in 2010, founded by Alan and Juliet Barratt. Its name comes from its first product, Thermo Detonator, described as “explosive” by early users. Since then, Grenade has expanded into a multi‑award‑winning range including its flagship Carb Killa protein bars—high‑protein, low‑sugar snacks that shook up the UK market after launching in 2015. Today, it operates in over 80 countries and has broadened into shakes, spreads and performance supplements. With bold, edgy branding and flavours that mimic indulgent confections, Grenade offers gym‑friendly nutrition without compromising on taste.
