Fulfil Chocolate Brownie Bar: What the Label Actually Tells You
Published · Updated · Sláinte Editorial
A Fulfil Chocolate Brownie bar makes two things very obvious from the front of the pack.
It is a protein bar.
And it is marketed around a relatively low sugar number.
Both are useful facts.
Neither tells you the whole product.
The manufacturer listing gives us a good example of how to read a protein bar beyond the headline.
The exact product
This article refers specifically to Fulfil Chocolate Brownie 55g.
Do not mix data from another Fulfil flavour or bar size.
The manufacturer page, checked in October 2026, listed per 55g bar:
- 197 kcal
- 19.7g protein
- 1.5g sugars
- 13.5g polyols
- 4.4g saturated fat
- 3.7g fibre
Nearly 20g protein
The bar lists 19.7g protein per 55g serving.
That is a substantial proportion of the product.
It also explains why the packaging can make protein such a prominent part of the proposition.
But protein should still be read alongside the rest of the label.
Only 1.5g sugars, so why is it sweet?
Because total sugars does not tell you every ingredient responsible for sweetness.
The ingredient list includes maltitol and sucralose.
These are not the same type of sweetening ingredient.
What is maltitol?
Maltitol is a polyol, also known as a sugar alcohol.
It can provide sweetness while contributing differently to the nutrition declaration than ordinary sugar.
The bar lists 13.5g polyols per bar.
That is why simply reading 1.5g sugars does not explain the entire carbohydrate formulation.
What is sucralose?
Sucralose is an intense sweetener.
Its European additive number is E955.
Sláinte has a separate evidence guide explaining sucralose and EFSA’s 2026 re-evaluation.

What about fibre?
The manufacturer listing gives 3.7g fibre per 55g bar.
That belongs in the product picture too.
Again, the point is not to collect positive and negative points until one “wins”. It is to understand the complete product.
Saturated fat
The listing gives 4.4g saturated fat per bar.
Someone focusing only on protein and sugars could easily miss that number.
That is why front-of-pack claims should not replace the nutrition table.
Calories
The bar provides 197 kcal per 55g serving according to the manufacturer page.
Calories alone do not tell you whether the bar is appropriate for your needs.
But the value matters for understanding the whole serving.
Low sugar is not the same as low energy
This product makes the distinction easy to see.
The bar can contain 1.5g sugars and still provide 197 kcal.
That is not contradictory.
Energy can come from protein, fat, carbohydrates including polyols and other ingredients.
Is it a good protein bar?
That depends on what you mean by good.
If you want a bar providing close to 20g protein with relatively little declared sugar, those facts are relevant.
If you care about saturated fat, polyols, fibre, total energy and ingredient composition, those need to be considered too.
There is no need to turn the bar into either a perfect health food or something to fear.
What the front of the pack cannot tell you
A protein headline does not tell you saturated fat.
A low-sugar headline does not tell you polyols.
A chocolate-brownie flavour does not tell you the ingredient formulation.
Turn the pack around.
What about digestive effects from polyols?
Some polyols can have laxative effects at higher intakes, and foods containing more than the applicable proportion of added polyols require specific EU labelling.
What this means when you’re shopping
When comparing protein bars, look beyond 20g protein and low sugar.
Compare:
- exact bar size
- protein
- total sugars
- polyols
- saturated fat
- fibre
- energy
- ingredients
Compare like with like.
A 40g bar and a 60g bar should not be treated as equal portions simply because both say “high protein”.
On Sláinte, the Fulfil Chocolate Brownie 55g bar scores 24 out of 100 (Bad). The protein and fibre count in its favour, but the sugar/fat density typical of a chocolate-coated bar, plus the sucralose sweetener, keep the score low.
