Who is Grenade?
Grenade is a British brand founded in 2010 by Alan and Juliet Barratt, headquartered in Solihull, West Midlands. In a decade, it has established itself as a European leader in protein bars, expanding beyond specialized aisles to service stations and British snack sections.
In March 2021, the Mondelēz International group—owner of many confectionery brands—acquired a majority stake in the company. This explains Grenade's current positioning: the brand no longer targets only bodybuilders but a much wider audience seeking a sweeter, lower-sugar alternative.
Carb Killa or Grenade Protein Bar: What's the difference?
None, and that's the first thing to know if you're looking for a Grenade Carb Killa. In September 2022, the brand officially rebranded its Carb Killa bar as Grenade Protein Bar. The historical name is still widely used—by customers, retailers, and search engines—but it refers to the same product, with the same structure and flavors.
In practice: if you type "Carb Killa," you're looking for Grenade's triple-layer protein bar. Depending on the manufacturing date and market, the packaging will bear one name or the other. There are not two different ranges.
What is the Grenade range worth?
What Grenade excels at is texture. This is where the game is played, and it's the area where the brand has taken the lead: a soft base, a crispy layer, a chocolate coating, resulting in a product that eats more like a confection than a supplement. Many competitors achieve the same protein content; few achieve the same texture.
What it does less well: everything else in the aisle. Grenade is not a powder brand, and its presence in France is mainly limited to snacking. If you're looking for a protein powder or a booster, this is not the place to look.
What are the flagship Grenade products we sell?
The Carb Killa bar
The product that made the brand. A 60g bar providing 23g of protein and less than 2g of sugar, for approximately 214 kcal. The proteins come from several dairy sources—calcium caseinate, milk protein isolate, whey isolate—which allows for extended assimilation. The sweet taste is achieved with polyols and sweeteners, mainly maltitol and xylitol.
One point deserves to be stated unequivocally: "less than 2g of sugar" does not mean "low calorie". At 214 kcal, a Carb Killa bar weighs about as much as a classic chocolate bar. Its value lies in its protein-to-calorie ratio, not its lightness: it's a good snack to tide you over until the next meal, not a free-volume diet food. Compare it to other protein bars in the aisle.
The Protein Spread
The brand's protein spread, formulated with whey concentrate, about 20% protein, with maltitol instead of sugar. It comes in several chocolate variations. It's more of a pleasure product than a performance one: it sweetens a pancake or toast without exploding sugar intake, but it remains fatty and caloric, like any spread. If the goal is to reduce calories, an additive-free peanut butter or a zero-sugar jam play a different role.
Our reseller opinion
What works. The Carb Killa remains one of the few protein bars you eat out of desire, not just discipline. The manufacturing consistency is good, the flavor choice is wide, and the protein-to-sugar ratio is truly well maintained.
The main limitation, and it's a real one: the Grenade selection we stock is very tight, and entirely focused on snacking. You won't build your supplementation around this brand with us. It complements an aisle, it doesn't structure it—and we prefer to say so rather than give the impression of a complete range.
Two additional reservations. First, polyols: the maltitol used in large quantities in these products is poorly tolerated by some, and regulations require stating that excessive consumption of polyols can have laxative effects. One bar is fine for most people; two or three a day, much less so. Second, the price: Grenade is priced as an established brand, and other bars in our aisle offer a better protein-to-price ratio.
Grenade or Warrior?
This is the most useful comparison: two brands targeting the same consumption occasion with opposite philosophies. Warrior is also British, but built on value for money: comparable triple-layer bar, slightly less protein, even wider flavor choice, significantly lower price. Grenade plays on established reputation and texture.
In practice: if you consume a bar occasionally and want the best taste experience, Grenade. If you eat several a week and budget matters, Warrior. And if you're looking for a different nutritional profile—fewer polyols, more fiber—look at PhD Nutrition or our other protein snacks.
Frequently Asked Questions
Is Grenade a good brand?
Yes, for protein bars, where it is one of the best on the market in terms of texture and consistency. Outside of snacking, it doesn't have much to offer and it's better to look elsewhere.
What is their best product?
The Carb Killa bar, no discussion. It's the historic product, the most accomplished, and the reason the brand exists.
How many Grenade bars can one eat per day?
One, in the vast majority of cases, and as a substitute for another snack rather than in addition. Two limitations combine. The first is caloric: at 214 kcal per unit, two bars add over 400 kcal to the day, which is enough to erase a moderate deficit. The second is digestive: these bars rely on maltitol and xylitol, and the accumulation of polyols in a single day causes bloating, gas, and sometimes more. A travel day might justify two; beyond that, meal structure needs to be re-evaluated.
Which Carb Killa flavor to choose?
Chocolate and caramel profiles are the most consensual, and these are where the brand's texture work is best expressed. White or milky flavors bring out the sweeteners more, lacking the bitterness of cocoa to balance them, and are much more divisive. Our advice is simple: buy two or three units of different flavors before committing to a box of twelve. In this category, taste is everything, and it cannot be read on any product sheet.
Does the Carb Killa contain gluten and allergens?
It contains milk, and depending on the flavors, soy, tree nuts, or peanuts—or traces thereof. Several references also contain wheat in the crispies, hence gluten. Recipes differ from one flavor to another and evolve over time: in case of a confirmed allergy or intolerance, only the label on the bar you hold is authoritative, even for a flavor you have already consumed.
Where to buy Grenade Carb Killa in France?
From specialized sports nutrition retailers, both online and in-store. Distribution in French supermarkets remains very partial, and the range of flavors is more limited there. We stock them in our store and ship throughout France.
Can a Carb Killa bar replace a meal?
No. It provides protein and calories, but not the micronutrient and fiber balance of a proper meal. Use it as a snack, not as a substitute. If you have weight loss goals or a medical condition, speak to your doctor or a dietitian.
Do Grenade bars make you gain weight?
No single food makes you gain weight in isolation: it's the daily caloric balance that matters. At 214 kcal, a bar can easily fit into a weight loss plan if it replaces another snack. It becomes a problem if it's added on top.
How to recognize an authentic product?
Go through a declared reseller and beware of classic signs: prices well below market, labeling without French mentions, very short expiry date, seller without a physical address. We source through the official channel.
Are Grenade products suitable for tested athletes?
No supplement can be considered risk-free by default. If you are subject to anti-doping controls, check batch by batch with the manufacturer and refer to the AFLD prohibited substances list. We do not claim any third-party anti-doping certification for this range.
Is Grenade available near Montpellier?
Yes. Carb Killa bars and the spread are available on the shelves of our store in Vendargues, about ten minutes from Montpellier. For bars, visiting the store has a concrete advantage: buying one unit of two or three flavors before committing to a whole box.
If you cannot visit, the selection can be ordered online and we ship throughout France and Europe. You will find it alongside our sugar-free grocery and our protein cookies.
