What is the PhD Nutrition Smart Bar?
PhD Smart Bar is a three-layer protein bar: a soft protein core, a caramel layer and crunchy soya crispies, the whole thing coated in chocolate. A 64 g bar provides 20 g of protein, 9 g of fibre and 245 kcal, for 12 g of carbohydrate and 12 g of fat.
PhD Nutrition is a British brand. The Smart Bar is its best-selling line, and its reputation rests not on its label but on its texture: it is one of the few bars in this aisle that you genuinely chew, instead of it sticking to your teeth or crumbling apart.
The flavours in the range: Chocolate Brownie, Cookies n Cream, Salted Fudge Brownie, Caramel Crunch, Birthday Cake, White Blondie, Milk Choc Hazelnut, Chocolat Peanut Butter and Chocolat Noir-Framboise. The rest of the brand can be browsed in our PhD Nutrition aisle, and the other lines in our protein bars selection.
What does a Smart Bar contain?
| Composition | Per 64 g bar | Per 100 g |
|---|---|---|
| Energy | 245 kcal | 383 kcal |
| Protein | 20 g | 31.3 g |
| Carbohydrate | 12 g | 18.8 g |
| Fat | 12 g | 18.8 g |
| Fibre | 9 g | 14 g |
| Salt | 0.4 g | 0.6 g |
| Coating | 31% chocolate, dark or milk depending on the flavour | |
20 g of protein for 245 kcal: that is one of the best ratios in the aisle, and it is this bar's whole reason for being. A third of the calories comes from protein. Compare it with an ordinary chocolate bar of the same weight — around 300 kcal and 4 g of protein — and you understand how the product is positioned.
The 9 g of fibre explain the dense texture, and they have a practical consequence. This is a bar you chew and that fills you up, not a confectionery item you swallow in three bites. The downside is flagged by the manufacturer itself: excessive consumption may have laxative effects, because of the fibre and above all the maltitol. The limit is set at two bars a day, and it is a sensible limit.
One point deserves a frank discussion: the protein blend combines milk protein, collagen hydrolysate and soya isolate. Milk protein and soya isolate are complete proteins. Collagen is not: it contains no tryptophan and it is low in several essential amino acids. It is used here for texture as much as to push up the “protein” line on the label. This is not a deception — the declared quantity is accurate — but 20 g of protein part of which is collagen is not worth 20 g of whey, and it is honest to say so.
From a regulatory standpoint, two authorised claims genuinely apply: protein contributes to a growth in and the maintenance of muscle mass, and the “source of fibre” statement is justified by the 14 g per 100 g. On the other hand, no joint claim is authorised for collagen, and no promise of satiety or weight control is permitted on this type of product. The manufacturer does not disclose the “of which sugars” line in the data available to us: refer to the packaging if that point matters to you.
Ingredients list
Protein blend (MILK protein, collagen hydrolysate, SOYA protein isolate), caramel layer [sweetener: maltitol, condensed MILK, cocoa butter, water, humectant: sorbitol, emulsifier: mono- and diglycerides of fatty acids, natural flavourings, salt], sweeteners (maltitol, sucralose), cocoa butter, cocoa SOYA crispies (7.8%) [soya protein, tapioca starch, cocoa powder], whole MILK powder, humectant (glycerol), coconut oil, natural flavourings, emulsifier (lecithins), bulking agent (microcrystalline cellulose), natural Bourbon vanilla flavouring. Coating: 31% dark or milk chocolate depending on the flavour.
Allergens: MILK and SOYA. May contain traces of GLUTEN, NUTS and EGGS. No palm oil, no preservative, no gelatine, natural colours only. Contains sweeteners: excessive consumption may have laxative effects.
How should the Smart Bar be eaten?
Portion: 1 bar, or half a bar if you are new to polyols. Drink: a glass of water, the fibre needs it. Timing: as a snack between meals, after training, or in place of a confectionery item. Frequency: two bars a day at most. Duration: no notion of a course, this is a food.
If you have never eaten a maltitol-based bar, start with half. That is not excessive caution: tolerance to polyols varies enormously from one person to another, and a whole bar can be enough to cause bloating and discomfort in someone sensitive. Half a bar already represents 10 g of protein.
Chew it, do not swallow it. It is a dense bar, designed to last: that is precisely what makes it useful as a mid-afternoon snack, when the aim is to hold out until the next meal rather than to fill a gap in thirty seconds.
Take it out of the fridge a quarter of an hour beforehand. Cold, the caramel layer turns hard and the chocolate snaps. At room temperature, the three-layer texture makes full sense. Conversely, in summer, do not leave it in a car: the coating melts and the bar loses its shape.
A bar tops up what you take in over the day, it does not replace a meal. If your aim is to cover a substantial protein intake, a serving of protein powder remains more effective and less expensive; the bar, for its part, wins on fitting into a bag.
Who is the Smart Bar for, and who is it not for?
It suits someone looking for a portable, indulgent snack with a real protein content and a controlled calorie profile. It is the typical gym-bag or desk-drawer product, and it is also an honest alternative to something from a vending machine.
It is not suitable for people allergic to milk or soya, both present in quantity in the recipe. Traces of gluten, nuts and eggs are possible. Nor is it suitable for vegan diets, because of the milk protein and the collagen hydrolysate, the latter being of animal origin.
It is to be avoided if you digest polyols poorly. Maltitol and sorbitol both appear in the list. If sugar-free chewing gum or “light” products usually upset you, this bar will upset you too. People with diabetes should also keep an eye on their blood sugar despite the low sugar content: polyols are not neutral.
What you should not expect from it. It does not make you lose weight, it does not replace a meal and it does not build muscle on its own. And the collagen it contains has no authorised joint effect: it is an ingredient for texture and protein content, nothing more. What you are buying is a practical snack with 20 g of protein — which is already a good reason.
Protein bar or protein cookie?
The two go in the same place in a bag, but they do not play the same role and the choice comes down to calories.
The bar is the format with the most protein per calorie: 20 g for 245 kcal here. That is what makes it suited to a period when you are watching your intake, or to a post-training snack when the next meal is still a long way off. It slips in anywhere and keeps for weeks.
A protein cookie plays on enjoyment and on satiety, in a far bigger format. Expect often twice the calories for an equivalent, or even lower, protein content. Our protein cookies aisle answers that particular need: the need for a real bit of baking, not a supplement.
And if what you are after above all is energy for a long effort rather than protein, neither really fits: an oat-based bar will provide more carbohydrate. Our protein snack aisle brings all these formats together for comparison, and the collagen aisle offers the dedicated products for those who really are looking for that protein.
Frequently asked questions
How much protein per bar?
20 g for a 64 g bar, i.e. 31.3 g per 100 g, and 245 kcal. The blend combines milk protein, collagen hydrolysate and soya isolate. Since collagen is not a complete protein, those 20 g are not strictly equivalent to 20 g of whey.
Which flavours are available?
In the range: Chocolate Brownie, Cookies n Cream, Salted Fudge Brownie, Caramel Crunch, Birthday Cake, White Blondie, Milk Choc Hazelnut, Chocolat Peanut Butter and Chocolat Noir-Framboise. The base is identical, the coating being dark or milk chocolate depending on the flavour.
Why can this bar cause bloating?
Because of the maltitol and the sorbitol, two polyols present in the caramel layer, and the 9 g of fibre. The manufacturer itself flags a possible laxative effect in the event of excessive consumption. If you are sensitive, start with half a bar and do not go beyond two a day.
Is the bar suitable for vegetarians?
No, because of the collagen hydrolysate, which is of animal origin. It also contains milk protein and whole milk powder, which likewise rules it out of vegan diets. The manufacturer does state, however, that it contains no gelatine.
What is the sugar content?
The manufacturer does not disclose the “of which sugars” line in the data available to us. We are not going to invent it: refer to the nutrition table printed on the packaging. What we do know is that the sweetness comes mainly from the maltitol and the sucralose.
Can you eat two in one day?
That is the limit set by the manufacturer, and it is a sensible one. Two bars represent 490 kcal and 40 g of protein, but also an amount of polyols that many people do not tolerate. Beyond that, digestive discomfort is predictable.
Does it contain palm oil?
No. The fats in the recipe are cocoa butter and coconut oil. The manufacturer also states the absence of preservative and gelatine, and the exclusive use of natural colours.
Where can you buy the PhD Nutrition Smart Bar?
The bar can be ordered individually from this page, in the available flavours, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, this is the bar we recommend first to anyone who has never eaten one: the texture is as close as this aisle gets to real confectionery. We simply give a warning about the maltitol, the first time. The rest of our selection can be browsed in the sports nutrition aisle.
What is the Grenade Carb Killa bar?
The Grenade Carb Killa is a single 60 g protein bar, built in three layers and coated in sweetened milk chocolate. It provides 23.2 g of protein and 214 kcal, which places it among the highest-protein bars in our protein bars range.
The protein comes from three milk fractions: calcium caseinate, milk protein isolate and whey protein isolate. The bar also contains 18.3% hydrolysed bovine gelatine, a figure declared by the manufacturer and one that has a direct consequence: this is not a vegetarian product. The rest of the list comprises polydextrose, glycerol, soya crispies, cocoa butter, skimmed milk powder, palm oil, three sweeteners (maltitol, xylitol, sucralose), flavourings, fat-reduced cocoa and soya lecithin. The flavours stocked: White Chocolat, Caramel, Cookie Dough, Peanut Nutter, Salted Peanut, Caramel Salé, Fudged Up, Oreo and Oreo White. The rest of the line-up is gathered in the Grenade collection.
What does a 60 g Carb Killa bar contain?
| Nutrient | Per 100 g* | Per 60 g bar | % NRV |
|---|---|---|---|
| Energy | 1,513 kJ / 357 kcal* | 908 kJ / 214 kcal | ** |
| Fat | 13.2 g* | 7.9 g | ** |
| of which saturates | not disclosed | not disclosed | ** |
| Carbohydrate | 22.7 g* | 13.6 g | ** |
| of which sugars | not broken down*** | not broken down*** | ** |
| Fibre | 11.2 g* | 6.7 g | ** |
| Protein | 38.7 g* | 23.2 g | ** |
| Salt | 0.72 g* | 0.43 g | ** |
* Column recalculated from the declaration per 60 g bar. ** No nutrient reference value is established for these nutrients. *** The “of which sugars” line is not broken down in the manufacturer data we hold, and we will not be reconstructing it. The packaging carries a reduced sugar content: refer to the label of the flavour you buy.
Two nutrition claims can be verified against these figures. Protein accounts for around 43% of the bar's energy value, which comfortably clears the regulatory threshold for the “high protein” claim. And at 11.2 g of fibre per 100 g, the bar clears the 6 g per 100 g threshold for the “high fibre” claim. Those are the only two statements of that kind we make on this page, because they are the only two the figures support.
When and how should you eat a Carb Killa?
- Serving: 1 bar of 60 g.
- Volume of liquid: the manufacturer prescribes none.
- Timing: within the 30 minutes after training, or as a snack between meals when the next meal is still a long way off.
- Frequency: 1 bar a day at most, following the manufacturer's recommendation.
- Duration: no course length is stated. A protein bar is a food, not a course.
Two practical points. If you digest polyols poorly, start with half a bar: the manufacturer explicitly recommends it. And once opened, the bar should be eaten within 48 hours; the chocolate coating copes badly with heat, which makes it a poor fit for a gym bag left in a car in summer. Our other snack formats can be found in our protein snacks range.
Who is the Carb Killa for, and who is it not for?
It suits you if you are after a portable protein hit, with no shaker and no water, for a working day, a trip or a late finish at the gym.
It is not suitable in four specific situations. If you are vegetarian or vegan: the 18.3% hydrolysed bovine gelatine rules it out, unambiguously. If you are allergic to milk or soya: both are declared as allergens, and the facility also handles gluten, tree nuts, peanuts, wheat and eggs. If you tolerate polyols poorly: the bar contains more than 10 g per 100 g, which triggers the regulatory statement “excessive consumption may produce laxative effects”. If you are diabetic: the manufacturer asks you to monitor your blood sugar despite the reduced sugar content, and that question is settled with your doctor, not with a product page.
The manufacturer also advises against it for under-18s and asks women who are pregnant or breastfeeding to consult a healthcare professional.
What you should not expect from it: at 214 kcal, a Carb Killa is a snack, not a meal replacement, and it will not make you lose weight. It usefully replaces a confectionery bar; it does not replace a dinner.
Carb Killa bar or a whey shake?
Both provide a comparable amount of protein, but they do not solve the same problem.
The bar wins on convenience. Nothing to measure out, nothing to wash, nothing to mix, and you can eat it on a train. It is the only format that fits in a pocket.
The shake wins on density and on cost. A serving of whey isolate provides an equivalent amount of protein for markedly fewer calories, with no fat and no polyols, and the price per gram of protein is in another league. If you are in a calorie deficit, the shake is mathematically the better choice, and our weight loss range starts from the same reasoning.
If it is the indulgent side that appeals to you rather than the bar format, protein cookies play on the same ground with different textures. And to build your baseline intake, the protein range is the one to look at first.
Frequently asked questions
Is the Grenade Carb Killa vegetarian?
No. It contains 18.3% hydrolysed bovine gelatine, an ingredient of animal origin. This is the most common question about this product and the answer is no, whatever the flavour.
How much sugar does a Carb Killa contain?
The “of which sugars” line is not broken down in the data the manufacturer has sent us, and we are not going to invent it. What we can state: 13.6 g of carbohydrate and 6.7 g of fibre per bar. The exact sugar figure is on the wrapper of each flavour.
Why can the bar cause bloating?
It contains more than 10 g of polyols per 100 g, which triggers the regulatory statement about the laxative effects of excessive consumption. Starting with half a bar is the manufacturer's recommendation for sensitive individuals.
Which flavour should you try first?
The caramel and peanut profiles are the fullest in flavour, the white chocolate and Oreo profiles the sweetest on the palate. If you cannot decide, take two different ones: at 60 g apiece, trying them costs little.
Can you eat several a day?
The manufacturer sets the limit at one bar a day. Beyond that, you are stacking up polyols, fat and calories with no extra protein benefit compared with a less processed protein source.
Does the bar contain palm oil?
Yes, palm oil appears in the ingredients list. We hold no verified information about its origin or its supply chain, and so we will write nothing further about it.
Does it keep well in summer?
Badly. The chocolate coating melts, and the manufacturer asks for storage in a cool, dry place, away from heat and moisture. A bar forgotten in a car in the sun will be inedible.
Where can you buy Grenade Carb Killa bars?
Carb Killa bars are available individually on this page, in the flavours stocked, and in our Vendargues shop, about ten minutes from Montpellier. It is the kind of product that is better bought in store the first time: you leave with two different flavours rather than a whole box of one you do not like.
We ship throughout France and Europe.
What is the Oat King bar by LSP Nutrition?
Oat King is an oat-flake bar in a distinctly more generous format than the aisle average. Each bar weighs 95 g, contains at least 42% oat flakes and provides 393 to 448 kcal depending on the flavour. The manufacturer states that the bars are made by hand, using traditional methods.
This is not a protein bar, and that is the first thing to understand before buying. A protein bar is built around an isolate, with 20 g of protein for 200 kcal. Here the logic is the opposite: oats are the first ingredient, the bar is dense in carbohydrate, and it exists to supply energy over time rather than to cover a protein intake.
The flavours in the catalogue: Big Tasty Chocolate, Chocolat Caramel, Chocolate Coconut, Carrot Cake, Apricot Yogurt, Red Fruits Yogurt, Super Banana, Cherry Almond, Maple Walnut, Peanut Butter and Lemon Poppy, the last of these being the vegan version. The rest of the brand can be browsed in our LSP Sports aisle, and the other snack formats in our protein bars aisle.
What does an Oat King bar contain?
| Composition | Per 95 g bar | Detail |
|---|---|---|
| Energy | 393 to 448 kcal | depending on the flavour |
| Oat flakes | 42% minimum | first ingredient in the recipe |
| Protein, carbohydrate, fat | not disclosed | varies with the flavour |
| Format | Individual 95 g bar | |
95 g and up to 448 kcal: that is the figure to keep in mind, and it changes how the product is used entirely. A typical bar on this aisle weighs 55 to 65 g for 200 to 230 kcal. Here you are at double that, which is to say the equivalent of a light meal. That is neither a flaw nor a virtue in itself: it is simply a product made for long efforts, not for filling the 16:00 slump.
42% oat flakes is a high proportion, and you can feel it as you chew. The texture is that of a dense cereal bar, not a soft coating around a protein dough. That is why it stays with you better than most of its competitors, and also why it needs to be eaten with water within reach.
We should flag what we do not have: the manufacturer does not publish the nutritional breakdown — protein, carbohydrate, fat, fibre, salt — for each flavour. We will not fill those boxes with approximate values, all the more so as the composition varies appreciably from one flavour to another. The full table appears on the wrapper of the bar you receive, and that is the only reliable source if you count your intake precisely.
In regulatory terms there is nothing to claim, and that is perfectly fine: no health claim is authorised for oats in the area of energy or endurance. Complex carbohydrates act as fuel for exercise, which is basic physiology. Be wary of phrases such as “sustained energy with no blood-sugar spike” that turn up all over this aisle: those are slogans, not authorised claims.
Ingredients list
The full ingredients list is not disclosed by the manufacturer in the data available to us, and it varies with the flavour. It appears on the wrapper of the bar you receive. What we do know: oat flakes account for at least 42% of the recipe and are its first ingredient.
May contain traces of PEANUTS, SOYA and NUTS. Some flavours also contain nuts or peanuts as an ingredient in their own right — that is the case with the Peanut Butter, Cherry Almond and Maple Walnut versions. Oats are among the gluten-containing cereals as defined by European regulation: this product is therefore not suitable for anyone with coeliac disease.
How do you eat the Oat King bar?
Portion: 1 bar, or half a bar as a snack. Drink: a large glass of water, as the bar is dense. Timing: 30 to 60 minutes before exercise, during a long activity, or straight after the session. Frequency: one bar a day is plenty. Duration: there is no notion of a course here, it is a food.
Its best use is long outdoor effort. A bike ride, a hike, a trail run, a day's skiing: this format exists for exactly that. 400 kcal in a jacket pocket, eaten on the move and not melting the way a chocolate bar does, is hard to match.
Before a gym session, reckon on half a bar and 30 to 60 minutes instead. A whole 95 g bar swallowed just before lifting is heavy to digest, and the oats do not help. Cut it in two and keep the rest for afterwards.
During a long effort, eat it in pieces and drink. This is a dry, dense bar; without water it goes down badly and gives that blocked-up feeling cyclists know well. Spread it over thirty minutes rather than swallowing it in one go.
Finally, keep it away from heat: dry and at room temperature. In a southern summer, a bar left in a car turns sticky and holds together far less well. If what you are after is a protein-oriented snack instead, our protein snack aisle answers a different need.
Who is the Oat King bar for, and who is it not for?
It suits someone who does an endurance sport, who is out for long stretches, or who struggles to meet their calorie needs across the day. It also works as a stopgap breakfast: 95 g of oats and dried fruit beats a croissant eaten standing up.
It is not suitable for anyone with coeliac disease, oats being one of the gluten-containing cereals as defined by the regulation. Nor is it suitable in cases of allergy to peanuts, soya or nuts: traces are possible across the whole range, and some flavours contain them outright.
It is poorly suited to a low-calorie diet. At 393-448 kcal a unit, one bar represents a significant share of a day in deficit. This is not a cutting product, and selling it as one would be dishonest. If your goal is weight loss, our weight loss aisle brings together products designed for that.
What not to expect from it. It is not a protein source: it does contain some, naturally present in the oats, but in modest and undisclosed amounts. It does not build muscle, does not improve performance by itself and does not replace a proper meal. What it provides is easily portable energy — and on that ground it is excellent.
Oat bar or protein bar?
This is the real choice facing anyone buying from this aisle, and it depends only on what you are looking for.
A protein bar is made for protein intake: around 20 g for 200 to 230 kcal, in a format half the size. It is the right product after a weights session, or as a snack when you need to hit a protein target without sending the calories through the roof. Our protein bars aisle covers those references.
The oat bar is made for energy: plenty of carbohydrate, enough mass to fill you up, and it holds up well in a pocket. For a long effort it wins hands down — a protein bar over three hours on a bike will not give you the fuel you need, whatever its protein content.
And if your need is purely for carbohydrate, to be prepared at home rather than carried with you, an oat flour or a rice cream works out far cheaper per gram. You pay for the bar's format, not for its composition — worth knowing.
Frequently asked questions
How many calories are in one bar?
From 393 to 448 kcal depending on the flavour, for a 95 g bar. That is roughly double a classic protein bar, which puts it closer to a light meal. It is deliberate: the bar is designed for long efforts, not for filling a small gap.
Which flavours are available?
In the catalogue: Big Tasty Chocolate, Chocolat Caramel, Chocolate Coconut, Carrot Cake, Apricot Yogurt, Red Fruits Yogurt, Super Banana, Cherry Almond, Maple Walnut, Peanut Butter and Lemon Poppy. The last of these is the vegan version of the range.
Does the bar contain gluten?
Yes. Oats, which account for at least 42% of the recipe, are one of the gluten-containing cereals as defined by European regulation. This product is therefore not suitable for anyone with coeliac disease or gluten intolerance.
What is the protein content?
The manufacturer does not disclose the full nutritional breakdown, and it varies with the flavour. We are not going to invent it. Bear in mind that this is not a protein bar: the protein it does contain comes from the oats and the dried fruit, in modest amounts.
Is it suitable before a weights session?
Half a bar, 30 to 60 minutes beforehand, yes. A whole bar right before you start will be heavy to digest: 95 g of dense oats is a lot to carry. For a long outdoor outing, on the other hand, the whole bar makes complete sense.
Is there a vegan version?
Yes, the Lemon Poppy flavour. The other flavours in the range are vegetarian, several of them containing dairy, notably the yogurt-based versions. Check the wrapper of the flavour you choose.
How should it be stored?
Dry and at room temperature, with the wrapper closed again if you do not finish it. Avoid leaving it in a car in full sun: the heat softens the binders and the bar holds together far less well. Check the best-before date before eating.
Where can you buy the Oat King bar by LSP Nutrition?
The bar can be ordered individually from this page, in the available flavours, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, this is the bar we put into the hands of cyclists and hikers: on the back-country roads, a 95 g bar does more for your outing than a sugary gel. The rest of our selection can be browsed in the sports nutrition aisle.
What is the Warrior Crunch Bar?
The Warrior Crunch Bar is a 64 g protein bar, built in three layers: a soft centre based on milk proteins, a caramel layer, and a milk chocolate coating sweetened with maltitol that on its own accounts for 31 % of the bar's weight. Between the two, soy crispies provide the crunch that gives the product its name.
It is made by Warrior, a British brand whose other products you will find in our Warrior category. The positioning is clear and unapologetic: this is a confectionery bar, not an austere athlete's bar. It plays on texture and on sweetness, where many rivals make do with a dry coating and a compact centre.
The flavours we stock, from Cookies & Cream to Raspberry Lemon Cheesecake, taking in Fudge Brownie, Banoffee Pie, Peanut Butter Cup and Birthday Cake. The nutritional base is identical from one flavour to another; what changes is the flavouring and sometimes the presence of a colouring. The list of variants available on this page is the definitive one.
What does a 64 g bar contain?
Here is the label, including the per-100 g column, because that is the only one that lets you honestly compare two bars of different weights.
| Values | Per 100 g | Per 64 g bar |
|---|---|---|
| Energy | around 373 kcal | 239 kcal |
| Fat | around 17.2 g | 11 g |
| of which saturates | around 9.5 g | 6.1 g |
| Carbohydrate | around 37.5 g | 24 g |
| of which sugars | around 3.6 g | 2.3 g |
| of which polyols | around 31.3 g | 20 g |
| Protein | around 31.3 g | 20 g |
| Salt | around 0.56 g | 0.36 g |
The per-100 g values are calculated from the manufacturer's label, which declares per whole bar. Warrior also states that the bar is high in fibre, without publishing a figure for the content: we will not reconstruct it.
20 g of protein is the top of the range for this category, and above all it really is 20 g: the blend combines milk proteins and hydrolysed collagen. That second source is worth flagging, because it is common in bars and rarely explained. Collagen is an incomplete protein, low in tryptophan, less effective than a milk protein for building muscle. If your priority is protein synthesis after a strength session, a shaker of whey isolate remains more effective gram for gram.
The most interesting point is the 20 g of polyols for only 2.3 g of sugars. Maltitol replaces sugar in the coating as well as in the centre. It provides around 2.4 kcal per gram instead of 4, and above all it does not raise blood glucose the way sucrose does. That is what explains how a bar this indulgent stays at 239 kcal.
The trade-off is on the fat side: 11 g, of which 6.1 g are saturates. That is a lot, and it comes from the chocolate and the palm fat. A single bar covers close to a third of the daily reference intake for saturates. It is not a manufacturing flaw, it is the price of that melting texture.
Ingredients list
Maltitol milk chocolate coating (31 %), sweetener maltitol, MILK proteins, hydrolysed collagen, SOYA crispies (SOYA protein isolate, rice flour, malted BARLEY extract, salt), humectants (glycerol, sorbitol), SOYA protein isolate, water, palm fat, condensed MILK, flavouring, emulsifiers (mono- and diglycerides of fatty acids), thickener (microcrystalline cellulose), salt, colours (plain caramel, beta-carotene). The flavourings and colours vary with the flavour.
How do you fit the Warrior Crunch Bar into your day?
Serving: one 64 g bar. Frequency: one a day, two at most if your fibre intake is already high and well tolerated. Timing: as an afternoon snack, or within the hour after training. Drink: a large glass of water, 250 to 300 ml, because polyols draw water into the gut. Duration: no notion of a course here, this is a food.
Its best use is the 16:00 slot or the journey home, when dinner is still a long way off and the real alternative is not a chicken breast but a pastry. Compared with a classic chocolate bar of the same weight, you gain a good twenty grams of protein and you divide the sugars by ten.
Before a session it is less suitable: the 11 g of fat and the polyols slow gastric emptying, and nobody enjoys lifting heavy on a full stomach. If you are looking for a quick intake before exercise, go for an easily digested simple carbohydrate such as cream of rice. After training, on the other hand, it does the job of a stopgap snack before the real meal very well.
A word on texture: the bar hardens in the cold. Straight out of the fridge it turns very hard and loses its appeal. Twenty minutes at room temperature, or ten seconds in the microwave, and the caramel runs again.
Who is the Warrior Crunch Bar for, and who is it not for?
It suits someone who struggles to hit their protein target over the day and has neither the time nor the inclination to make up a shaker. It also suits those keeping an eye on their sugars, since 2.3 g per bar is a very low figure for a product that tastes this sweet.
Declared allergens: milk, soya, gluten — the gluten comes from the malted barley extract in the crispies. The manufacturer also flags possible traces of nuts, eggs and peanuts. It is therefore unsuitable for people with coeliac disease, and for anyone allergic to soya or to milk proteins. Nor is it vegetarian in the strict sense, since the hydrolysed collagen is of animal origin.
The real point to watch remains digestive. 20 g of polyols in a single bar is a high dose, and the regulatory wording “excessive consumption may produce laxative effects” is not a turn of phrase. If you have never had maltitol, start with half a bar. Some people tolerate three bars a day without feeling a thing, others regret the first.
What you should not expect from it: this is not a meal replacement, and it is not a cutting product. At 239 kcal and 6.1 g of saturates, it fits into a calorie budget, it does not reduce one. Nor does it replace a complete protein source across the day. If you have any doubt related to medication, to diabetes or to a known digestive disorder, ask your doctor or pharmacist for advice.
Warrior Crunch or a protein cookie?
This is the comparison that comes up most often over the counter, because the two products occupy the same afternoon slot and cost roughly the same.
A protein cookie generally weighs 60 to 75 g, provides 15 to 20 g of protein, but keeps real sugar rather than polyols. The result: it goes higher in calories, it sits better digestively, and it can be eaten in one go without wondering whether you will regret it. It is the better choice if you have a sensitive stomach, if you are bulking and the calories are working for you, or if you dislike the aftertaste of sweeteners.
The Warrior Crunch, for its part, keeps the advantage as soon as the calorie budget is tight and sugar has to stay low. At 2.3 g of sugars and 239 kcal, it slips into a cutting day without doing any damage, which a 350 kcal cookie does not always allow. And on the enjoyment front, the triple layer clearly beats a dry compressed bar.
If neither of the two suits you, the protein snack category brings together the other formats: crisps, wafers, bake-at-home mixes.
Frequently asked questions
How much sugar does the Warrior Crunch Bar actually contain?
2.3 g per 64 g bar, or around 3.6 g per 100 g. The 20 g of polyols shown on the “carbohydrate” line are not sugars: they are bulk sweeteners, maltitol in this case, which provide less energy and do not raise blood glucose in the same way.
Do polyols cause stomach upset?
In some people, yes, especially beyond 20 g over the day. It is a well-known and harmless reaction: polyols are not completely absorbed and draw water into the gut. Start with half a bar to gauge your tolerance, and drink normally.
Does the bar contain gluten?
Yes. The soy crispies contain a malted barley extract, which makes the bar unsuitable for people with coeliac disease or gluten intolerance. The manufacturer also declares milk and soya as allergens, with possible traces of nuts, eggs and peanuts.
What is the difference between milk proteins and hydrolysed collagen?
Milk proteins provide the full set of essential amino acids. Hydrolysed collagen does not: it is very low in tryptophan and unbalanced in several others. Here it plays a role in texture as much as in content. In practical terms, the 20 g stated are not worth 20 g of protein powder for building muscle.
Can you eat one every day?
One a day poses no problem if the rest of your diet is balanced. Two start to weigh on the saturates: 12.2 g in total is more than half the daily reference intake. The limiting factor is not the protein, it is the fat.
Which flavour should you choose for a first try?
The chocolate flavours — Fudge Brownie, Dark Chocolate Peanut Butter, Chocolate Chip Cookie Dough — are the closest to classic confectionery and the least divisive. The fruity flavours, Raspberry Lemon Cheesecake above all, split opinion more: the acidity stands out more because of the sweeteners.
Does it replace a meal?
No, and it should not be used that way. One bar provides 239 kcal and no portion of vegetables, complex fibre or micronutrients in any useful amount. It replaces a snack, or a pastry. Lunch, no.
Where can you buy the Warrior Crunch Bar?
The flavours can be ordered from this page, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, this is the product we hand out to taste most often: with a bar, the label never tells the whole story, and two people will not have the same opinion of the same maltitol. The rest of our sweet range can be browsed in our sports nutrition category.
What is the Per4m Protein Bar?
It is a 62 g protein bar coated in milk chocolate, supplying 20 g of protein for 200 kcal. The flavours listed, from Dubai Chocolate to Baklava by way of Salted Caramel and Cookie Dough.
It is built in three layers: a protein blend at 37%, a caramel-flavoured layer at 10% and a milk chocolate coating at 15%. Sugar is replaced by maltitol, a polyol, and by oligofructose; vegetable glycerol acts as a humectant and gives the bar its softness.
One point about the composition needs raising straight away, because it changes how you read the label: the protein blend combines milk proteins, soya isolate crispies and hydrolysed bovine collagen. We come back to it below. The full range sits in our Per4m aisle, and the category as a whole in protein bars.
What does a 62 g bar contain?
| Nutrient | Per 62 g bar | Per 100 g* | % NRV |
|---|---|---|---|
| Energy | 836 kJ / 200 kcal | 1,348 kJ / 323 kcal | — |
| Protein | 20 g | 32.3 g | 40% |
| Carbohydrate | 14 g | 22.6 g | — |
| of which sugars | not disclosed | not disclosed | — |
| of which polyols | not disclosed | not disclosed | — |
| Fat | 8.5 g | 13.7 g | — |
| of which saturates | not disclosed | not disclosed | — |
| Fibre | 5.1 g | 8.2 g | — |
| Salt | 0.3 g | 0.48 g | — |
| Calcium | 120 mg | 194 mg | 15% |
| Potassium | 180 mg | 290 mg | 9% |
* Column calculated from the values declared for one bar. Three lines are missing from the data supplied, and they are not trivial ones: sugars, polyols and saturates. Yet maltitol appears twice in the ingredients list, as the main sweetener of both the bar and the coating. We will not publish a figure we do not have: read the label on the bar you receive, particularly if your digestion reacts to polyols.
What is solid, on the other hand, really is solid. Twenty grams of protein for 200 kcal means that 40% of the bar's energy comes from protein — double the 20% threshold that allows the “high protein” claim. It is one of the best ratios in the aisle, and it can be checked. The 5.1 g of fibre, that is 8.2 g per 100 g, also clear the “high fibre” threshold, set at 6 g per 100 g. And the 120 mg of calcium at 15% of the NRV allow the “source of calcium” claim, which is rare on a bar.
Now for the nuance that matters, and that the aisle never mentions. Hydrolysed bovine collagen is part of the protein blend. Collagen is an incomplete protein: its essential amino acid profile is very poor, in tryptophan especially. It counts in full towards the 20 g declared for labelling purposes, without bringing the same value as a milk protein. Since the manufacturer does not publish the split between the three sources, we cannot say what share of the total it represents. It is worth knowing before you compare this bar with another.
The applicable wording remains the only authorised one: protein contributes to a growth in and the maintenance of muscle mass. For calcium, at 15% of the NRV: calcium contributes to normal muscle function and is needed for the maintenance of normal bones.
How does this bar fit into the day?
Serving: 1 bar of 62 g. Liquid: 250 ml of water, as the bar is dense. Timing: after training, as a snack between two meals, or as a dessert. Frequency: one bar a day. Duration: none, it is a food.
Two hundred kilocalories is a proper snack and not a trivial nibble. For comparison, it is the energy equivalent of a large banana with a yoghurt — but with 20 g of protein instead of 5. That is exactly what makes the product worthwhile: the ratio, not the idea that it is “light”, which it is not.
The most relevant use is the one where nothing else is possible: a trip, a day with no break, a session followed by two hours of travel. That is where a bar beats a shake, because it needs no water, no shaker and no fridge. At home, a bowl of fromage blanc will do the same job for less.
On timing, let us keep it plain: there is no thirty-minute window to hit after training. The day's protein total matters more than the slot. Eat it when you are genuinely short of protein.
Store it dry, at room temperature and away from direct light. As the coating is milk chocolate, it melts in a car in summer — the only real drawback of the format in our part of the world.
Who is this bar for, and who is it not for?
It suits those who need a portable protein snack, and those looking for a treat that counts towards their totals rather than an ordinary chocolate bar. The flavours, squarely in dessert territory, are a genuine argument: boredom is the leading cause of people giving up in this aisle.
It contains MILK and SOYA, and may contain GLUTEN. The manufacturer declares it unsuitable for people allergic to NUTS and PEANUTS. It is aimed at adults; pregnant and breastfeeding women should seek advice before consuming it, as with any supplement.
It does not suit vegetarians: hydrolysed bovine collagen is of animal origin, which the name “protein bar” gives no hint of. It is a point we flag as a matter of course over the counter. It suits you less well if you tolerate polyols poorly: maltitol is the main sweetener, and its content is not declared. Excessive consumption of polyols may produce laxative effects; one bar is generally well tolerated, two or three much less so.
What you should not expect from it: this is not a weight-loss product. Two hundred kilocalories added to an already complete day remain 200 kcal added. A protein bar is only worthwhile if it replaces something — an afternoon snack, a pastry, a ruined meal. Stacked on top of everything else, it does nothing more than what its label says.
Per4m Protein Bar or Grenade Carb Killa?
These are the two bars most often compared over the counter, and we sell both.
The Grenade range is built on a bar that is lighter in weight, around 60 g, with a protein profile that is often entirely dairy and a crunchier texture. It is the better choice if you want to avoid collagen in the protein blend, or if you prefer a bar that crunches to one that is soft.
The Per4m wins on three measurable points: 40% of its energy supplied by protein, 5.1 g of fibre and 15% of the NRV in calcium, which few bars can show. It also offers flavours you will not find elsewhere. Its triple-layer texture — coating, caramel centre, crispies — really does come close to confectionery, which is an argument if the bar has to stand in for a dessert.
If your need is simply to add protein at the lowest cost, neither is the right choice: a shake from the protein aisle costs two to three times less for the same intake. You buy a bar for its convenience and its taste, not for its price-to-protein ratio. The other snack formats can be compared in our protein snacks and protein cookies aisles.
Frequently asked questions
Does all 20 g of protein come from milk?
No. The protein blend combines milk proteins, soya isolate and hydrolysed bovine collagen. Collagen is an incomplete protein, very poor in essential amino acids, but it counts in full towards the declared total. The manufacturer does not publish the split between the three sources.
How much sugar is in one bar?
The manufacturer does not declare that line in the labelling data available to us, any more than the polyol line, even though maltitol is the main sweetener. We will not publish an unverified figure: refer to the label on the bar you receive.
Is the bar suitable for vegetarians?
No. The hydrolysed bovine collagen in the protein blend is of animal origin. It is a piece of information that often comes as a surprise, since the name “protein bar” suggests a dairy or plant-based product only.
Can it cause digestive upset?
Maltitol is a polyol, and excessive consumption of polyols may produce laxative effects. One bar a day is generally well tolerated; two or three much less so, all the more since 5.1 g of fibre and oligofructose come with it. If you are sensitive, start with half a bar.
Is 200 kcal a lot for a snack?
It is a proper snack, the energy equivalent of a large banana with a yoghurt — but with 20 g of protein instead of 5. It is not a trivial nibble: it makes sense if it replaces something, less so if it is added to an already complete day.
Which flavour should you choose?
Chocolate Brownie and Cookie Dough are the safe bets, in a classic register. Dubai Chocolate and Baklava are the most marketed, enjoyable now and then but wearing after a few bars. Salted Caramel and Chocolate Peanut Butter are the sweetest on the palate. Note that flavour availability varies with deliveries.
Should you eat it right after training?
No. The thirty-minute window is an outdated notion: it is the protein total over twenty-four hours that counts. Eat the bar at the moment when you have no other decent option — that is where, and only where, it beats a real meal or a shake.
Where to buy the Per4m Protein Bar?
The available flavours can be ordered from this page, and we ship throughout France and Europe. The assortment moves with deliveries: it is an aisle worth checking regularly.
At the Vendargues shop, about ten minutes from Montpellier, this is the aisle where people buy singles before committing to a whole box, and that is the right instinct: a bar you do not like stays in the cupboard, whatever its nutritional values. The rest of the snacks can be compared in our sports nutrition section, and dedicated collagen sources in their own aisle.
What is the ESN Designer Protein Bar?
The ESN Designer Protein Bar is a 45 g protein bar, coated and filled, designed to deliver protein in a format that fits in a pocket. What sets it apart is the way it is sweetened: sugar is very largely replaced here by maltitol, a polyol. That choice explains both its appeal and its main limitation, and we will go into both.
The protein base is a blend of milk proteins and soy protein isolate. Then come maltitol, cocoa butter, glycerol as a humectant — it is what stops the bar from going hard — whole milk powder, and finally the elements specific to each flavour. The list above is the one for the Almond Coconut version; the composition changes from one flavour to another, particularly where nuts are concerned.
The flavours listed: Almond Coconut, Cinnamon Cereal, Dark Chocolate Salted Almond, Dark Cookie White Choc, Fudge Brownie, Hazelnut Nougat, Peanut Caramel, White Chocolate Pistachio, Strawberry Yogurt, Dark Chocolate Raspberry, Strawberry White Chocolate and White Chocolate Raspberry. The German brand is stocked here in our ESN section.
What does a 45 g bar contain?
| Nutrient | Per 100 g | Per 45 g bar |
|---|---|---|
| Energy | 1,537 kJ / 368 kcal | 692 kJ / 166 kcal |
| Fat | 16 g | 7.2 g |
| of which saturates | 8.4 g | 3.8 g |
| Carbohydrate | 30 g | 14 g |
| of which sugars | 3.2 g | 1.4 g |
| of which polyols | 25 g | 11 g |
| Fibre | 1.4 g | 0.6 g |
| Protein | 31 g | 14 g |
| Salt | 0.40 g | 0.18 g |
Figures taken from the Almond Coconut flavour. They vary from one flavour to another — a white chocolate pistachio version does not have the same fat profile as a raspberry one. Read the label on the bar you are buying if you are counting to the gram.
14 g of protein for 166 kcal is the figure that justifies the purchase. Protein here supplies around a third of the bar's energy, which allows the nutrition claim “high protein” within the meaning of the European regulation. In practical terms, you are roughly halfway between a Greek yoghurt and a shake: it is not a serving of whey, but it is well above what a supermarket cereal bar provides.
1.4 g of sugars per bar — that is 3.2 g per 100 g — allows the claim “low sugars”. Let us be plain about it, because the confusion is common: this is not a “sugars-free” bar. That particular wording would require less than 0.5 g per 100 g, and we will not be using it. The sugar has been replaced by 11 g of maltitol per bar, a polyol that provides sweetness and around 2.4 kcal per gram instead of 4.
The line to watch, on the other hand, is the 7.2 g of fat, of which 3.8 g is saturates. That is what sets this bar apart from a shake: it is richer, more filling, and more calorific for the same protein. That is neither good nor bad in itself — it is information to factor in if you are counting your calories.
How does this bar fit into the day?
Dose: 1 bar of 45 g. Liquid: none, but have a glass of water to hand, the texture is dense. Timing: as a snack between meals, after a session, or at the end of a meal. Frequency: 1 to 2 a day at most, for the reason explained below. Duration: none, this is a food.
The most honest use case is the stopgap snack. A day when you have no time to eat properly, a trip, a late afternoon where the real alternative is the vending machine: there, 14 g of protein for 166 kcal solves the problem better than a croissant. After training, it does the job if you have no shaker to hand, and no more than that.
A storage remark that matters: keep it between 15 and 20 °C, away from direct heat. Left in a car in summer, the coating melts and the bar becomes impossible to eat cleanly. Conversely, straight out of a fridge it hardens noticeably — let it come back to room temperature for ten minutes.
Do not use it as a meal replacement. It has neither the volume, nor the composition, nor the micronutrients of a meal. It is a snack, and if you eat three a day to avoid cooking, you are making life harder rather than easier — a tub of protein powder costs less per serving and takes thirty seconds to prepare.
Who is this bar for, and who is it not for?
It suits anyone looking for a portable protein source, anyone who dislikes shakes, and anyone who wants something sweet that is compatible with a weight-loss goal without resorting to shop-bought cakes.
It is not for you if you tolerate polyols badly. That is the point to know before buying, not after. The manufacturer carries the regulatory statement: excessive consumption may produce laxative effects. With 11 g of maltitol per bar, two bars in a day are enough to cause bloating, wind or intestinal discomfort in sensitive people. If you have irritable bowel syndrome, stick to one, or give it a miss.
Allergens: the bar contains MILK, SOYA and, depending on the flavour, NUTS. Traces of GLUTEN and PEANUTS are possible. The almond, hazelnut and pistachio flavours are obviously the ones most concerned — check the flavour as much as the product.
What not to expect from it: this is not a slimming product. 166 kcal are still 166 kcal, and a bar added to an already complete day is a more calorific day. Its value lies in replacing something else, not in being added on top. Nor is it a performance product, and maltitol is in no way an active ingredient: it is a bulk sweetener.
A protein bar or a whey shake?
That is the real question, and the answer depends entirely on your day. Let us compare like with like: 14 g of protein here for 166 kcal, against roughly 22 to 24 g of protein for 110 to 120 kcal in a standard serving of concentrated whey.
The shake wins on the numbers, and it wins by a wide margin: more protein, fewer calories, a lower cost per serving. If your aim is to cover a daily protein total at the best possible ratio, the powder is the rational choice, no argument.
The bar wins on everything else, and that everything else counts for more than people think. It calls for no shaker, no water and no rinsing. It can be eaten on the train, in a meeting, between two appointments. It is chewed, so it satisfies more than a liquid of the same calorie count. And above all, it actually gets eaten: a bar in a bag is consumed, a shake that has to be made up is often skipped. The best supplement remains the one you actually take. The sensible compromise is this: the powder at home, the bar on the move. The rest of the range can be compared in our protein snacks and our protein cookies.
Frequently asked questions
Is this bar really sugar-free?
No, and we will not write that it is. It contains 1.4 g of sugars per bar, that is 3.2 g per 100 g. That allows it the claim “low sugars”, which requires less than 5 g per 100 g, but not the wording “sugars-free”, reserved for products under 0.5 g per 100 g. The difference is a regulatory one, and it is real.
Why 11 g of polyols, and is that a problem?
Maltitol replaces sugar: it sweetens almost as much for around 2.4 kcal per gram instead of 4, and it is only partly absorbed. That is what makes it possible to declare 1.4 g of sugars. The trade-off is digestive — the legal statement “excessive consumption may produce laxative effects” appears on the packaging, and it is not decorative.
Can you eat several a day?
Two at most, and only one if your gut is sensitive. The limit comes not from the protein but from the polyols: at three bars, you are at 33 g of maltitol, which causes discomfort in a great many people. Add to that 498 kcal, which is no longer a snack.
Which flavour should I choose to start with?
The classic chocolate flavours — Fudge Brownie, Hazelnut Nougat, Peanut Caramel — are the most widely liked and the closest to confectionery. The fruity versions such as Strawberry White Chocolate or Dark Chocolate Raspberry divide opinion more. If you are allergic to nuts, rule out Almond Coconut, White Chocolate Pistachio and Dark Chocolate Salted Almond from the start.
Does it contain gluten?
Gluten is not an ingredient in the Almond Coconut version, but traces are possible, as they are for peanuts. Since the composition varies from one flavour to another, if you have coeliac disease, read the label of the precise flavour you are buying and, at the slightest doubt, leave it.
Is it suitable during a cutting phase?
Yes, provided it replaces something. 166 kcal for 14 g of protein is a decent ratio, and 3.8 g of saturates remains modest. But it is a dense bar, not a free food: build it into your daily total like any other snack.
Is it suitable for vegetarians or vegans?
For vegetarians, yes: the base is a blend of milk and soy proteins, with no meat ingredient. For vegans, no — the milk proteins and the whole milk powder rule it out. For a vegan diet, look to our plant proteins.
Where can you buy the ESN Designer Protein Bar?
The flavours can be ordered from this page, and we ship anywhere in France and Europe.
With a bar, buying blind is a gamble: the flavour is the only thing that decides whether you will buy again, and no photo tells you that. At our Vendargues shop, around ten minutes from Montpellier, the right move is to take two or three different ones rather than a whole box of the same taste — it is less of a commitment and it saves you ending up with eleven bars you do not like.
What is a protein bar really for?
A protein bar is a convenient emergency solution, not a superior food. It solves a logistical problem: protein when you don't have a kitchen, a shaker, or ten minutes to spare. It fits in a pocket, keeps at room temperature, and can be eaten on the go. This is its entire purpose, and it's a real one.
Compared to a shaker, it loses on two counts. Price: for the same amount of protein, a dose of powder is significantly cheaper, because in a bar you also pay for the coating, individual packaging, and manufacturing. Density: a shaker provides protein and almost nothing else, while a bar adds fats, carbohydrates, and often polyols. At home, a shaker of whey isolate or clear whey does the job better, for less money.
Compared to a real meal, it loses even more significantly. Two eggs, a Greek yogurt, a can of tuna with bread: same amount of protein, more micronutrients, more satiety, and a negligible cost. The bar is a situational tool—train, office, gym, skipped lunch—and in these cases, it's better than what you would have eaten instead.
How to read a protein bar label?
Protein per bar, not per 100g
The nutrition panel is expressed per 100g. A bar claiming "30g of protein" might only contain 17g if it weighs 55g. Read the "per serving" column, or do the math with the weight listed on the package. An honest bar contains around 15 to 20g of protein for 50 to 65g, which is about a third of its weight.
Polyols and their digestive effect
Maltitol, sorbitol, xylitol, isomalt: bulk sweeteners that replace sugar and provide texture. They are incompletely absorbed in the small intestine and ferment in the colon, leading to bloating and gas in sensitive individuals, or if two are consumed in a day. European regulations require the mention "excessive consumption may produce laxative effects" for polyol content over 10%. Erythritol is an exception: absorbed and then eliminated through urine, it causes much less discomfort. If bars upset your stomach, first check which polyol is used.
Added fibers, hidden sugars, real calories
Inulin, fructo-oligosaccharides, polydextrose: these fibers bulk up the bar and lower the stated digestible carbohydrate content. They are not bad, but they also ferment. Regarding sugars, glucose syrup, dates, or concentrated grape juice are still sugars, even in so-called natural bars: the "of which sugars" line does not lie, unlike the front of the package. Finally, a bar is most often between 190 and 250 kcal, the equivalent of a pastry. The difference lies in the composition, not the total: the bar provides protein and is more satiating. But two bars a day "because it's diet-friendly" adds 400 to 500 kcal to your daily intake.
Dry bar, coated bar, or cereal bar?
The dry protein bar is the most dense and stripped-down: compressed milk proteins, low fat, firm, sometimes floury texture. The most nutritionally effective, the least pleasant to eat.
The confectionery-style coated bar made the category successful: soft core, chocolate coating, more fats, often more polyols, a less favorable protein/calorie ratio. However, it's the best for long-term adherence: a bar you don't want to eat ends up in a drawer. This is the format of Grenade's Carb Killa, Warrior's Crunch Bar, or PHD's Smart Bar, and the Rabeko range plays on the same field of acknowledged pleasure.
The protein cereal bar is a compromise: oats, puffed rice, a little added protein, often 8 to 12g per bar for a significant carbohydrate portion. It's not strictly a protein bar, but an energy snack, useful before a workout or during prolonged exertion: this is the logic behind LSP Nutrition's Oat King.
When should you eat a protein bar?
As a snack, between two widely spaced meals: this is its most relevant use, filling a four or five-hour gap without afternoon cravings. When traveling—airport, highway, business trip—it has no serious competitors.
Before a workout, allow 45 to 90 minutes: a bar rich in fiber and polyols eaten fifteen minutes before an intense training session will be felt during your sets. Afterward, it helps out but isn't the best choice: fats and fibers slow digestion, whereas you want the opposite. A protein shaker is superior if you have one on hand.
Do protein bars help you lose weight?
No, and no food makes you lose weight: what causes weight loss is a sustained calorie deficit. The bar can contribute to this or hinder it, depending on how it's used.
What is true: it's portioned, which prevents eating "just a little" from a whole packet of biscuits, and it provides protein, which is more satiating than carbohydrates or fats for the same calories.
What is false: that it's low in calories, that it "burns" anything, or that you can eat it freely. Its risk during a period of restriction is being consumed in addition to meals rather than instead of something else. If your goal is weight loss, count it in your total like any other food.
How to make homemade protein bars?
No-bake recipe, for six bars. Dry mix 60g of oat flour (or blended rolled oats), 60g of flavored protein powder, and a pinch of salt. Add 60g of warmed peanut butter, then 40 to 70ml of milk or plant-based drink, one spoon at a time, until you get a compact, moldable dough that no longer sticks to your fingers.
Press firmly into a baking paper-lined mold, about 1.5 cm thick. Refrigerate for at least two hours, then cut into six bars. For the coating, melt 40g of dark chocolate, drizzle over the bars, and chill for ten minutes. Storage: four to five days in the refrigerator.
Two technical points. Use concentrated whey, or a blend containing some casein, rather than pure isolate: isolate absorbs a lot of liquid and results in a crumbly texture. And add liquid gradually—a dough that's too wet will never set when chilled.
What about a vegan protein bar?
Vegan protein bars rely on a blend of pea, rice, soy, and sometimes hemp proteins. This blend is not a marketing ploy: pea is low in methionine, rice in lysine, and combining them provides an essential amino acid profile comparable to dairy proteins. A bar built on a single plant source is nutritionally less interesting.
Texture remains the weak point. Plant proteins retain less water and result in a sandier texture; manufacturers compensate with nut butters, dates, or chicory syrup, which increases fats or carbohydrates. A vegan bar is therefore rarely as light as a dairy-based bar, but it has a clear advantage for people with lactose intolerance. Our powdered plant proteins meet the same need at home, and Lenny & Larry's cookies offer a plant-based snack alternative.
Frequently Asked Questions
What is a protein bar?
A bar-shaped food where approximately one-third of its weight consists of protein, most often milk proteins, sometimes plant-based. The rest is a combination of carbohydrates, fats, added fibers, and polyols designed to achieve an edible texture and long shelf life at room temperature. It is neither a dietary supplement nor a diet product: it is a snack, whose only true quality compared to an ordinary chocolate bar is its protein content and the satiety that comes with it.
Why eat a protein bar?
For situational reasons, never because it would be superior to a regular food: it provides 15 to 20g of protein when you don't have a kitchen, a shaker, or time to eat. Office, train, gym, skipped lunch: in these situations, it's significantly better than what you would have had instead. At home, a shaker costs less, and a real meal is better in every way.
When to eat a protein bar?
Its best time is as a snack, between two meals spaced four or five hours apart, when the late afternoon craving sets in. Before exercise, allow 45 to 90 minutes: fibers and polyols consumed fifteen minutes before an intense session will be felt during your sets. After the session, it helps out, but fats and fibers slow digestion—a shaker is better if you have one. In the evening, it's acceptable provided it's accounted for in your daily intake.
How many protein bars per day?
One, generally. Two might be justified on a travel day; beyond that, you accumulate polyols, fermentable fibers, and calories for a benefit that no longer increases. Protein should primarily come from meals.
What is the best protein bar?
The one you will actually eat, and whose ratio holds up. Three criteria, in order: at least one-third of the weight in protein, or 17 to 20g for a 55 to 60g bar, calculated per bar and not per 100g; a sweetener that doesn't bother you, erythritol being significantly better tolerated than maltitol; a taste and texture you can tolerate long-term. The highest-protein bar on the shelf isn't the best if it's chalky: an opened box that ends up in the back of the cupboard is useless.
How to choose a protein bar?
By reading the label in four steps, in this order. First, the weight of the bar, to convert the "per 100g" table into actual grams per bar. Then, the protein/calorie ratio: 20g of protein for 200 kcal is a good benchmark, 12g for 250 kcal is a confectionery. The type of sweetener: erythritol and stevia are well-tolerated, maltitol much less so. Finally, the "of which sugars" line, even on bars marketed as natural—dates and concentrated syrups are still sugars. Taste is the deciding factor between two bars that are equivalent on these four points, and it's a legitimate criterion.
Which is the highest protein bar?
The densest bars on the market contain about 40% protein by total weight, which is around twenty grams for a 50 to 60g bar. Beyond that, the texture becomes dry and floury: this is a manufacturing constraint, not a lack of willingness from brands. Be wary of front-of-package claims—a "30g protein" bar might weigh 90g and be proportionally less rich than a 55g bar with 20g. Always relate it to weight, and remember that a 40% bar you don't like is less useful than a 33% bar you actually finish.
Do protein bars make you gain weight?
Not by themselves, but they can easily contribute to it when added to meals instead of replacing them. A bar typically weighs 190 to 250 kcal, the equivalent of a pastry: two a day represent 400 to 500 kcal added to your total. The word "protein" on the packaging does not make a food light. If taken instead of a snack you would have consumed anyway, the bar is neutral, or even favorable, as it provides better satiety for the same calories. If taken as a supplement because it's perceived as diet-friendly, it simply pushes your caloric balance upwards.
Do protein bars make you lose weight?
No. No food makes you lose weight: only a sustained caloric deficit achieves this. What the bar provides during a diet is more modest and very real: it is portioned, which prevents eating "just a little" from a whole package, and its proteins are more satiating than carbohydrates for the same calories. It becomes counterproductive as soon as it adds to meals instead of replacing a snack. At 190-250 kcal each, two daily bars are enough to cancel out a moderate deficit.
Are protein bars bad for your health?
No, they are ordinary processed foods, neither toxic nor miraculous, and one bar a day poses no problem for a healthy adult. Three honest caveats though. Polyols, poorly absorbed, cause bloating and a laxative effect beyond two bars—European regulations even require this warning on the packaging. The calories are similar to a pastry, which the word "protein" easily makes people forget. Finally, they do not replace whole foods: systematically substituting meals with bars impoverishes the intake of fiber, vitamins, and minerals.
Why do I have stomach pain after a protein bar?
Three causes, in order of frequency: polyols (maltitol first and foremost), added fibers like inulin, and residual lactose from milk proteins. Switching to an erythritol version or a plant-based version often solves the problem; for lactose issues, digestive enzymes can help. If discomfort persists, consult a doctor.
Is a bar after exercise enough?
For casual training, yes. For progression goals, an intake of 20 to 30g of protein is more relevant than the 15 to 20g of an average bar, and a shaker provides it faster and for less money. The timing itself is not urgent: the two hours following the session are suitable.
Protein bar or whey shaker?
The shaker wins at home: cheaper, more customizable dosage, better digested around exercise. The bar wins everywhere else: a shaker requires water, a container, and a place to wash it.
Can I eat it in the evening?
Yes, provided it's accounted for in your daily intake. For a late-night snack, casein is more suitable due to its slow digestion.
How to make homemade protein bars?
No-bake and in ten minutes: 60g of oat flour, 60g of flavored protein powder, a pinch of salt, 60g of warmed peanut butter, then 40 to 70ml of milk added spoon by spoon until you get a dough that no longer sticks. Press to 1.5 cm thick, refrigerate for two hours, cut into six. Two pitfalls to avoid: whey isolate, which absorbs too much liquid and makes the bar crumbly—prefer a concentrate or a blend with some casein—and excess liquid, which prevents it from setting when cold. They last four to five days in the refrigerator, as the homemade version has no preservatives.
What's the difference between a protein bar and a protein cookie?
The format and density: a protein cookie is larger, higher in calories, and richer in carbohydrates; a bar is more concentrated in protein per calorie. Compare with our protein cookies and our protein snacks.
Which bars to choose from our selection?
We select bars based on three criteria: actual protein content relative to weight, type of sweeteners, and taste—a bar that's good on paper but unpleasant won't be eaten. For coated bars, Grenade's Carb Killa, Warrior's Crunch Bar, PHD's Smart Bar, and Per4m's Protein Bar cover different textures and profiles; ESN's Designer Protein Bar offers a denser option. For cereal bars, LSP Nutrition's Oat King is an oat bar, more energetic than protein-rich, suitable for pre-workout and long efforts. To place the bar within a complete diet plan, see our mass gain and sports nutrition sections.
Can I try a bar before buying the box?
A bar is primarily chosen by taste, and taste cannot be read on any product sheet. At our store in Vendargues, about ten minutes from Montpellier, bars can be bought individually: you test one or two, then come back for a box of the one you like. This is the best way to avoid an opened box lingering in the back of the cupboard. We ship throughout France for refills.

What is a protein bar really for?
A protein bar is a convenient emergency solution, not a superior food. It solves a logistical problem: protein when you don't have a kitchen, a shaker, or ten minutes to spare. It fits in a pocket, keeps at room temperature, and can be eaten on the go. This is its entire purpose, and it's a real one.
Compared to a shaker, it loses on two counts. Price: for the same amount of protein, a dose of powder is significantly cheaper, because in a bar you also pay for the coating, individual packaging, and manufacturing. Density: a shaker provides protein and almost nothing else, while a bar adds fats, carbohydrates, and often polyols. At home, a shaker of whey isolate or clear whey does the job better, for less money.
Compared to a real meal, it loses even more significantly. Two eggs, a Greek yogurt, a can of tuna with bread: same amount of protein, more micronutrients, more satiety, and a negligible cost. The bar is a situational tool—train, office, gym, skipped lunch—and in these cases, it's better than what you would have eaten instead.
How to read a protein bar label?
Protein per bar, not per 100g
The nutrition panel is expressed per 100g. A bar claiming "30g of protein" might only contain 17g if it weighs 55g. Read the "per serving" column, or do the math with the weight listed on the package. An honest bar contains around 15 to 20g of protein for 50 to 65g, which is about a third of its weight.
Polyols and their digestive effect
Maltitol, sorbitol, xylitol, isomalt: bulk sweeteners that replace sugar and provide texture. They are incompletely absorbed in the small intestine and ferment in the colon, leading to bloating and gas in sensitive individuals, or if two are consumed in a day. European regulations require the mention "excessive consumption may produce laxative effects" for polyol content over 10%. Erythritol is an exception: absorbed and then eliminated through urine, it causes much less discomfort. If bars upset your stomach, first check which polyol is used.
Added fibers, hidden sugars, real calories
Inulin, fructo-oligosaccharides, polydextrose: these fibers bulk up the bar and lower the stated digestible carbohydrate content. They are not bad, but they also ferment. Regarding sugars, glucose syrup, dates, or concentrated grape juice are still sugars, even in so-called natural bars: the "of which sugars" line does not lie, unlike the front of the package. Finally, a bar is most often between 190 and 250 kcal, the equivalent of a pastry. The difference lies in the composition, not the total: the bar provides protein and is more satiating. But two bars a day "because it's diet-friendly" adds 400 to 500 kcal to your daily intake.
Dry bar, coated bar, or cereal bar?
The dry protein bar is the most dense and stripped-down: compressed milk proteins, low fat, firm, sometimes floury texture. The most nutritionally effective, the least pleasant to eat.
The confectionery-style coated bar made the category successful: soft core, chocolate coating, more fats, often more polyols, a less favorable protein/calorie ratio. However, it's the best for long-term adherence: a bar you don't want to eat ends up in a drawer. This is the format of Grenade's Carb Killa, Warrior's Crunch Bar, or PHD's Smart Bar, and the Rabeko range plays on the same field of acknowledged pleasure.
The protein cereal bar is a compromise: oats, puffed rice, a little added protein, often 8 to 12g per bar for a significant carbohydrate portion. It's not strictly a protein bar, but an energy snack, useful before a workout or during prolonged exertion: this is the logic behind LSP Nutrition's Oat King.
When should you eat a protein bar?
As a snack, between two widely spaced meals: this is its most relevant use, filling a four or five-hour gap without afternoon cravings. When traveling—airport, highway, business trip—it has no serious competitors.
Before a workout, allow 45 to 90 minutes: a bar rich in fiber and polyols eaten fifteen minutes before an intense training session will be felt during your sets. Afterward, it helps out but isn't the best choice: fats and fibers slow digestion, whereas you want the opposite. A protein shaker is superior if you have one on hand.
Do protein bars help you lose weight?
No, and no food makes you lose weight: what causes weight loss is a sustained calorie deficit. The bar can contribute to this or hinder it, depending on how it's used.
What is true: it's portioned, which prevents eating "just a little" from a whole packet of biscuits, and it provides protein, which is more satiating than carbohydrates or fats for the same calories.
What is false: that it's low in calories, that it "burns" anything, or that you can eat it freely. Its risk during a period of restriction is being consumed in addition to meals rather than instead of something else. If your goal is weight loss, count it in your total like any other food.
How to make homemade protein bars?
No-bake recipe, for six bars. Dry mix 60g of oat flour (or blended rolled oats), 60g of flavored protein powder, and a pinch of salt. Add 60g of warmed peanut butter, then 40 to 70ml of milk or plant-based drink, one spoon at a time, until you get a compact, moldable dough that no longer sticks to your fingers.
Press firmly into a baking paper-lined mold, about 1.5 cm thick. Refrigerate for at least two hours, then cut into six bars. For the coating, melt 40g of dark chocolate, drizzle over the bars, and chill for ten minutes. Storage: four to five days in the refrigerator.
Two technical points. Use concentrated whey, or a blend containing some casein, rather than pure isolate: isolate absorbs a lot of liquid and results in a crumbly texture. And add liquid gradually—a dough that's too wet will never set when chilled.
What about a vegan protein bar?
Vegan protein bars rely on a blend of pea, rice, soy, and sometimes hemp proteins. This blend is not a marketing ploy: pea is low in methionine, rice in lysine, and combining them provides an essential amino acid profile comparable to dairy proteins. A bar built on a single plant source is nutritionally less interesting.
Texture remains the weak point. Plant proteins retain less water and result in a sandier texture; manufacturers compensate with nut butters, dates, or chicory syrup, which increases fats or carbohydrates. A vegan bar is therefore rarely as light as a dairy-based bar, but it has a clear advantage for people with lactose intolerance. Our powdered plant proteins meet the same need at home, and Lenny & Larry's cookies offer a plant-based snack alternative.
Frequently Asked Questions
What is a protein bar?
A bar-shaped food where approximately one-third of its weight consists of protein, most often milk proteins, sometimes plant-based. The rest is a combination of carbohydrates, fats, added fibers, and polyols designed to achieve an edible texture and long shelf life at room temperature. It is neither a dietary supplement nor a diet product: it is a snack, whose only true quality compared to an ordinary chocolate bar is its protein content and the satiety that comes with it.
Why eat a protein bar?
For situational reasons, never because it would be superior to a regular food: it provides 15 to 20g of protein when you don't have a kitchen, a shaker, or time to eat. Office, train, gym, skipped lunch: in these situations, it's significantly better than what you would have had instead. At home, a shaker costs less, and a real meal is better in every way.
When to eat a protein bar?
Its best time is as a snack, between two meals spaced four or five hours apart, when the late afternoon craving sets in. Before exercise, allow 45 to 90 minutes: fibers and polyols consumed fifteen minutes before an intense session will be felt during your sets. After the session, it helps out, but fats and fibers slow digestion—a shaker is better if you have one. In the evening, it's acceptable provided it's accounted for in your daily intake.
How many protein bars per day?
One, generally. Two might be justified on a travel day; beyond that, you accumulate polyols, fermentable fibers, and calories for a benefit that no longer increases. Protein should primarily come from meals.
What is the best protein bar?
The one you will actually eat, and whose ratio holds up. Three criteria, in order: at least one-third of the weight in protein, or 17 to 20g for a 55 to 60g bar, calculated per bar and not per 100g; a sweetener that doesn't bother you, erythritol being significantly better tolerated than maltitol; a taste and texture you can tolerate long-term. The highest-protein bar on the shelf isn't the best if it's chalky: an opened box that ends up in the back of the cupboard is useless.
How to choose a protein bar?
By reading the label in four steps, in this order. First, the weight of the bar, to convert the "per 100g" table into actual grams per bar. Then, the protein/calorie ratio: 20g of protein for 200 kcal is a good benchmark, 12g for 250 kcal is a confectionery. The type of sweetener: erythritol and stevia are well-tolerated, maltitol much less so. Finally, the "of which sugars" line, even on bars marketed as natural—dates and concentrated syrups are still sugars. Taste is the deciding factor between two bars that are equivalent on these four points, and it's a legitimate criterion.
Which is the highest protein bar?
The densest bars on the market contain about 40% protein by total weight, which is around twenty grams for a 50 to 60g bar. Beyond that, the texture becomes dry and floury: this is a manufacturing constraint, not a lack of willingness from brands. Be wary of front-of-package claims—a "30g protein" bar might weigh 90g and be proportionally less rich than a 55g bar with 20g. Always relate it to weight, and remember that a 40% bar you don't like is less useful than a 33% bar you actually finish.
Do protein bars make you gain weight?
Not by themselves, but they can easily contribute to it when added to meals instead of replacing them. A bar typically weighs 190 to 250 kcal, the equivalent of a pastry: two a day represent 400 to 500 kcal added to your total. The word "protein" on the packaging does not make a food light. If taken instead of a snack you would have consumed anyway, the bar is neutral, or even favorable, as it provides better satiety for the same calories. If taken as a supplement because it's perceived as diet-friendly, it simply pushes your caloric balance upwards.
Do protein bars make you lose weight?
No. No food makes you lose weight: only a sustained caloric deficit achieves this. What the bar provides during a diet is more modest and very real: it is portioned, which prevents eating "just a little" from a whole package, and its proteins are more satiating than carbohydrates for the same calories.

Questions fréquentes — Protein Bars
Une barre protéinée, c'est quoi ?
Un aliment formaté en barre dont un tiers du poids environ est constitué de protéines, le plus souvent des protéines de lait, parfois végétales. Le reste est un assemblage de glucides, de lipides, de fibres ajoutées et de polyols qui donne la texture et permet une conservation longue à température ambiante. C'est une collation, et sa force est là : un apport protéique franc dans un format qui se glisse partout.
Pourquoi manger une barre protéinée ?
Pour une raison de circonstance : elle apporte 15 à 20 g de protéines là où vous n'avez ni cuisine, ni shaker, ni le temps de manger. Bureau, train, salle de sport, déjeuner qui saute : dans ces situations, c'est l'option la plus simple et la plus protéinée à portée de main.
Quand manger une barre protéinée ?
Son meilleur moment est la collation, entre deux repas espacés de quatre ou cinq heures, quand la fringale de fin d'après-midi s'installe. Avant le sport, laissez 45 à 90 minutes de marge, le temps que fibres et polyols soient digérés. Après la séance, elle a l'avantage d'être immédiatement disponible, dans le sac. Le soir, elle se prend très bien à condition d'être comptée dans la journée.
Combien de barres protéinées par jour ?
Une par jour s'intègre sans y penser, deux sur une journée de déplacement. Comme pour toute source de fibres et de polyols, répartissez-les plutôt que de les enchaîner, et laissez les repas porter l'essentiel de l'apport protéique.
Quelle est la meilleure barre protéinée ?
Celle que vous mangerez réellement, et dont le ratio tient la route. Trois critères, dans l'ordre : au moins un tiers du poids en protéines, soit 17 à 20 g pour une barre de 55 à 60 g, calculé par barre et non pour 100 g ; un édulcorant qui vous convient, l'érythritol étant le mieux toléré ; un goût et une texture que vous avez envie de retrouver. Les trois comptent autant, parce que la barre la plus utile est celle qui finit dans votre sac chaque semaine.
Comment choisir une barre protéinée ?
En quatre lectures d'étiquette, dans cet ordre. Le poids de la barre, d'abord, pour convertir le tableau « pour 100 g » en grammes réels par barre. Le rapport protéines / calories ensuite : 20 g de protéines pour 200 kcal est un bon repère. La nature de l'édulcorant : érythritol et stévia passent très bien, le maltitol demande d'y aller plus doucement. La ligne « dont sucres » enfin, y compris sur les barres présentées comme naturelles — dattes et sirops concentrés sont des sucres. Le goût tranche entre deux barres équivalentes sur ces quatre points, et c'est un critère légitime.
Quelle est la barre la plus protéinée ?
Les barres les plus denses du rayon montent à environ 40 % de protéines sur le poids total, soit une vingtaine de grammes pour une barre de 50 à 60 g. C'est la limite haute que permet la texture. Repère de lecture : rapportez toujours le chiffre de la face avant au poids de la barre — une barre de 55 g à 20 g de protéines est proportionnellement plus riche qu'une barre de 90 g annonçant 30 g.
Les barres protéinées font-elles grossir ?
Non. Une barre pèse le plus souvent 190 à 250 kcal, et elle se compte dans la journée comme tout autre aliment. Prise à la place d'une collation, elle joue même en votre faveur : à calories égales, ses protéines rassasient davantage qu'une collation sucrée. C'est tout l'intérêt du format portionné, qui donne un chiffre clair plutôt qu'un paquet ouvert.
Les barres protéinées sont-elles mauvaises pour la santé ?
Non, ce sont des aliments ordinaires, et une barre par jour s'intègre sans difficulté chez un adulte en bonne santé. Deux points pratiques à connaître. Les polyols, mal absorbés, peuvent provoquer ballonnements et effet laxatif en quantité — la réglementation européenne impose cet avertissement sur l'emballage, et l'érythritol est la forme la mieux tolérée. Et la barre est une collation : elle complète des repas complets, elle ne les remplace pas systématiquement.
Pourquoi ai-je mal au ventre après une barre protéinée ?
Trois causes, par ordre de fréquence : les polyols (maltitol en tête), les fibres ajoutées type inuline, et le lactose résiduel des protéines de lait. Passer à une version à l'érythritol ou à une version végétale règle souvent le problème ; sur le versant lactose, des enzymes digestives peuvent aider. Si la gêne persiste, parlez-en à un médecin.
Une barre après le sport, est-ce suffisant ?
Pour un entraînement de loisir, oui. Sur un objectif de progression, visez 20 à 30 g de protéines sur la collation d'après-séance : une barre dense y arrive, ou une barre complétée d'un yaourt ou d'un shaker si vous rentrez chez vous. Le délai, lui, n'a rien d'urgent : les deux heures qui suivent la séance conviennent.
Barre protéinée ou shaker de whey ?
Les deux couvrent deux moments différents. Le shaker est le format de la maison et de la salle : dosable au gramme, digéré vite autour de l'effort. La barre est le format du reste de la journée : rien à préparer, rien à laver, rien à transporter en plus. Beaucoup de pratiquants ont les deux, et c'est le choix le plus simple.
Peut-on en manger le soir ?
Oui, à condition de la compter dans la journée. Pour une collation nocturne, une caséine reste plus adaptée en raison de sa digestion lente.
Comment faire des barres protéinées maison ?
Sans cuisson et en dix minutes : 60 g de farine d'avoine, 60 g de protéine en poudre parfumée, une pincée de sel, 60 g de beurre de cacahuète tiédi, puis 40 à 70 ml de lait ajoutés cuillère par cuillère jusqu'à obtenir une pâte qui ne colle plus. Tassez sur 1,5 cm, deux heures au réfrigérateur, coupez en six. Deux écueils à éviter : la whey isolate, qui absorbe trop de liquide et rend la barre friable — préférez une concentrée ou un mélange avec un peu de caséine — et l'excès de liquide, qui empêche la prise au froid. Comptez quatre à cinq jours de conservation au réfrigérateur, la version maison n'ayant aucun conservateur.
Quelle différence avec un cookie protéiné ?
Le format et la densité : un cookie protéiné est plus gros, plus calorique et plus riche en glucides, la barre est plus concentrée en protéines par calorie. Comparez avec nos cookies protéinés et nos snacks protéinés.
