Who is the Grenade Carb Killa single bar for, and what makes it different?
The Carb Killa is the candy-bar killer — triple-layered (soft protein centre + crunchy crispies + chocolate coating) so the texture genuinely beats most candy bars while delivering 21g protein and as low as 1g sugar. (varies by flavour — see the nutrition facts image above for the exact macros of each one) For: gym-goers, keto/low-carb eaters, diabetics replacing sugar snacks (consult MD — still contains maltitol), candy-bar swappers cutting junk food, halal customers (per product tag — verify on packaging), and anyone who finds other protein bars too chalky. UK's #1 protein bar every year since 2017. Try a single first to find your favourite flavour, then upgrade to a box of 12 for best $/bar value. Pairs well with a GHOST Energy or Alani can for pre-workout pairing, or a Barebells / Built Bar / David bar for protein-bar variety rotation.
What does it taste like, and any prep tips?
Triple-layered structure: soft chewy protein centre + crunchy crispies + premium chocolate coating. Three distinct textures in every bite. Owner top picks: Chocolate Chip Cookie Dough, OREO (Official Collab), Caramel Chaos, Chocolate Chip Salted Caramel. 15 flavours total including limited editions like Creme Egg, Jaffa Quake, and seasonal collabs. Microwave tip: 10–15 seconds for a gooier centre — works especially well with Fudged Up and Caramel Chaos. Summer shipping: chocolate-coated bars can soften in warm transit; refrigerate flat 1–2 hours to reshape if needed. Only Onward Checkout+ covers heat-related shape damage.
What are the macros and net carbs?
Per bar (60g): approximately 21g protein, 1–2g sugar, 17g sugar alcohols (polyols/maltitol), 2–7g fibre depending on flavour. Calories vary by flavour — Chocolate Chip Cookie Dough is around 208 kcal, and others fall in a similar range. Always reference the nutrition facts panel image above for your specific flavour. Net Carbs formula: Net Carbs = Total Carbs − Fibre − Sugar Alcohols. Carb Killa bars typically land at 0–2g net carbs — true to the "Carb Killa" name. Sugar alcohol note: 17g maltitol per bar is on the higher end. If you're maltitol-sensitive, limit to 1 bar/day.
Allergens, certifications, and dietary fit?
All flavours contain milk and soy. Depending on the flavour, bars may also contain wheat, gluten, eggs, nuts, peanuts, or sesame seeds — check the specific flavour label before buying. Not all flavours are gluten-free — most are GF but some contain wheat. Halal: per product tag, most Carb Killa flavours are halal-certified (HFA in the UK); limited-edition collab flavours like Creme Egg may have different status — verify on current packaging. Vegetarian: suitable per typical Carb Killa formulation. NOT vegan (contains milk). Informed Choice / Informed Sport: per product tags, some Grenade production batches are Informed Sport tested — competitive athletes (WADA / NCAA) should verify the batch code on informed-sport.com before relying on it. Returns: 30-day on opened bars (≤7 if a multi-pack). Onward Checkout+ extends to 90 days + damage protection + 5% cash back.
