About Grenade
Grenade was founded in Birmingham, England, in 2010 by Alan and Juliet Barratt with one goal: to create the highest-performing protein bar that did not taste like cardboard. The Carb Killa bar launched in 2015 and within two years became the best-selling protein bar in the UK — a title it has held every year since. The formula is built around a multi-layer construction that no competitor has successfully replicated: a soft, chewy protein centre, a layer of crunchy crispies, and a premium chocolate coating. Every bite has three distinct textures.
Grenade is now sold in over 90 countries. At Top Nutrition & Fitness we carry one of the widest Grenade selections in Canada — including limited edition flavours and collab bars that are difficult to find outside of specialty stores.
Why Top Nutrition & Fitness Carries This Brand
We added Grenade to our lineup because our customers kept asking for it — and once we tasted the bars ourselves, there was no question. The Carb Killa is in a different category from most protein bars: the texture is genuinely candy-bar quality, the macros are hard to beat at 21g protein and under 2g sugar in most flavours, and the flavour lineup is constantly expanding with serious innovation. The OREO collab alone is a top-three seller in our entire bar category. This is the bar we recommend to anyone who tells us protein bars are too chalky, too sweet, or too boring.

Flavour Guide
Every Carb Killa bar shares the same triple-layered structure — a soft, chewy protein centre, crunchy crispies, and a chocolate coating — but each flavour brings something different. Here is what to expect from each option available in the box format.
Chocolate and Fudge Flavours
- Chocolate Chip Cookie Dough — Rich milk chocolate coating with a soft, doughy centre and chocolate chip pieces throughout. The closest thing to eating raw cookie dough with 21g of protein. Consistently one of the top-selling flavours at Top Nutrition & Fitness.
- Fudged Up — Dense, deep chocolate from coating to centre. The interior is noticeably softer and more fudgy than other flavours. Pure chocolate without competing flavours — if chocolate is what you want, this delivers it completely.
- Dark Chocolate Mint — Dark chocolate coating over a cool mint-flavoured centre. Refreshing, not overly sweet. Similar vibe to an After Eight — but with a protein hit and crunchy crispies layered in.
- Dark Chocolate Raspberry — Dark chocolate shell with a lightly tart raspberry-flavoured centre. Slightly fruity, slightly tangy. A good break from pure chocolate flavours if you find most bars too rich.
Caramel and Salted Flavours
- Caramel Chaos — Milk chocolate coating over a sticky caramel-flavoured centre with crunchy crispies. Sweet, lightly salty, and chewy. The flavour that feels most like a classic candy bar — Snickers energy without the Snickers sugar.
- Chocolate Chip Salted Caramel — Caramel Chaos with chocolate chip pieces added and a stronger salty finish. The sweet-salty contrast makes this one of the most addictive flavours in the lineup. A favourite among repeat customers.
- White Chocolate Salted Peanut — White chocolate coating with a peanut-flavoured centre and visible peanut pieces. Creamy, nutty, and lightly salted. If you love peanut butter cups, this is your Carb Killa flavour.
Peanut and Nut Flavours
- Peanut Nutter — Milk chocolate coating over a smooth, genuine peanut butter centre. Strong peanut flavour — not artificial. One of the original Carb Killa flavours and still a fan favourite after a decade on shelves.
White Chocolate and Dessert Flavours
- White Chocolate Cookie — White chocolate coating with a vanilla cookie-style centre and small crunchy pieces. Sweeter and lighter than the dark chocolate options. Creamy, smooth, and easy to enjoy daily without flavour fatigue.
- Birthday Cake — White chocolate coating over a sweet vanilla centre with colourful sprinkle-style pieces. Light, fun, and celebration-forward. Tastes like vanilla frosting in protein bar form.
- Lemon Cheesecake — White chocolate coating with a tangy lemon-flavoured centre. Zesty and refreshing with a creamy finish. Unique within the Carb Killa lineup — for customers who want something completely outside the chocolate spectrum.
Fruity and Citrus Flavours
- Jaffa Quake — Milk chocolate coating over an orange-flavoured centre. Inspired by the classic Jaffa Cake — chocolate and orange together in every bite. Bright, slightly tangy, and familiar.
Collab and Limited Edition Flavours
- OREO (Official Collab) — Milk chocolate coating over a cookies-and-cream centre with real OREO cookie pieces. Crunchy, creamy, instantly recognizable. One of the top sellers in the entire Grenade lineup — do not sleep on this one.
- OREO White (Official Collab) — White chocolate coating with the same OREO cookie crumble centre. Sweeter and creamier than the original OREO version. If you prefer white chocolate, this is the obvious pick over the standard OREO.
- Creme Egg (Limited Edition — Box of 18) — Milk chocolate coating over a sweet, creamy fondant-style centre inspired by the Cadbury Creme Egg. Only available while stock lasts. Note: this flavour ships as a box of 18, not 12.
Not sure which flavour to commit to for a full box? Try a few single bars first, then come back for the box of your favourite.
Single Bar vs. Box of 12 — Which One Is Right for You?
The single Grenade Carb Killa bar is the right choice for first-time buyers and anyone exploring new flavours. Low commitment, easy to mix and match across the full lineup.
The box of 12 is for customers who know their flavour and want the best price. At $54.99 per box, you pay approximately $4.58 per bar compared to $4.99 for individual bars — saving $0.41 per bar, or $4.92 per box. Over 80% of our repeat Grenade customers order boxes.
Suggested Stack
Get the most out of your Carb Killa supply by pairing it with:
- A pre-workout supplement — fuel your training session and follow it up with a Carb Killa for recovery and protein
- A whey protein powder — shakes for home meals, Carb Killa for on-the-go protein between meals
- Grenade Carb Killa Protein Spread — another high-protein, low-sugar option from Grenade — great on rice cakes, toast, or pancakes for variety in your high-protein snack rotation
What Our Customers Say
Grenade Carb Killa has 35 reviews on our store with an exceptional average rating. Here are highlights from our verified buyers:
"Best protein bar I have ever tried. The Chocolate Chip Cookie Dough actually tastes like the real thing. I order a box every two weeks and I have never been disappointed." — Verified buyer, Montreal
"Switched from Quest bars to Grenade about a year ago and never looked back. The texture is so much better — it actually has a proper chocolate coating. The OREO flavour is unreal." — Verified buyer
"I was skeptical about a bar with 21g protein and only 1g sugar tasting this good, but Grenade pulled it off. The Birthday Cake is my favourite — it legitimately tastes like cake frosting." — Verified buyer
FAQ
What makes Grenade the UK's number 1 protein bar?
Grenade Carb Killa holds the top-selling protein bar position in the UK based on retail sales data from multiple consecutive years. The combination of 21g protein, triple-layered texture, low sugar, and genuine flavour innovation has made it the benchmark product in the global protein bar category.
Is this a meal replacement?
No. Carb Killa is a high-protein snack designed to complement your meals and reduce sugar-heavy snacking. For a complete meal, pair a bar with whole foods.
Can I eat one every day?
Yes. A 12-bar box gives you nearly two full weeks of daily snacking. The low sugar and high protein profile makes it suitable for daily use without nutritional concerns.
Is it keto-friendly?
Yes. Low net carbs across all flavours makes Carb Killa compatible with standard ketogenic macro targets.
Is it good for fat loss?
Yes. High protein promotes satiety, which reduces overall calorie intake. Low sugar means no unnecessary calorie spikes from snacking. It is one of the most fat-loss-compatible treat bars available.
When should I eat it?
Post-workout, mid-afternoon, as a late-night dessert swap, or between meals — any time you want protein without reaching for junk food.
How should I store a box of 12?
Store in a cool, dry place. No refrigeration needed. Bars have a long shelf life, making bulk buying practical.
Does Carb Killa contain allergens?
All flavours contain Milk and Soy. Depending on the flavour, bars may also contain Wheat, Gluten, Eggs, Nuts, Peanuts, and Sesame Seeds. Check individual flavour labels before purchasing.
Where can I buy Grenade Carb Killa in Canada?
Top Nutrition & Fitness in Montreal is one of the largest Grenade retailers in Canada. We carry singles, boxes of 12, and limited edition flavours. We ship across Canada — no duties, no customs fees.
How does Carb Killa compare to a regular chocolate bar?
A regular 50g chocolate bar (e.g., Kit Kat) has approximately 5–6g protein, 20–25g sugar, and around 230 calories with minimal nutritional value. Carb Killa delivers 21g protein, 1–3g sugar, and a similar calorie count — with a filling macronutrient profile. It is not a compromise. It is a straight-up upgrade.
