ESN Designer Protein Bar

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?

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 The sugar has been replaced by 11 g of maltitol per bar, a polyol that provides sweetness and around 2.4 kcal per gram instead of 4.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.
