Overview
This Brownie bar sits in a wide range of Fibre Boost products that all follow a similar blueprint: high protein, high fibre, and almost no sugar. Compared with its Caramel Honey Macadamia sibling, it's virtually identical on the numbers, trading a fraction of a gram of protein for a fraction less sugar. The 33.3g of protein per 100g is well ahead of the 27g category average for protein bars, while the 0.7g of sugar per 100g is a tiny fraction of the typical 10.6g. It's a profile that leans hard into function over indulgence, using a short ingredient list to get there. The protein comes from a blend of whey and milk isolates, a quality combination. With almonds and walnuts in the mix, there's a real-food texture here that many bars lack. The 'cold pressed' method helps retain some of that, avoiding the baked, cookie-like feel of other products. Ultimately, this is a bar for someone who reads the label. The high fibre content makes it quite filling for its size, and the low calorie count makes it a smart swap for a chocolate bar in the afternoon. We see it as a desk-drawer staple or a gym-bag refuel.
Protein Score: 10.0/10
On the shelf, this bar stands out for those who prioritise protein efficiency above all else. Its 12.6g of protein for every 100 calories is a huge number, backed by a full 20g of protein per serve, earning a Protein Score/10. The protein density is significantly ahead of the typical product in this category, landing it at the top of the field. It's a genuine protein-first snack, delivering a hit comparable to dedicated recovery bars, not just a snack with a bit of protein sprinkled in. This makes it a solid choice for a post-gym refuel when you don't have a shaker handy. While some bars use lower-quality protein sources to hit a number, the use of whey and milk isolates here signals a focus on quality.
Clean Score: 9.6/10
There are no artificial sweeteners, colours, or preservatives on this label, just a short list of recognisable ingredients. This minimalist approach, with only one natural sweetener, is rare in the snack aisle and helps it achieve a Clean Score/10. With just 10 ingredients, this bar has less than half the additives and fillers of the average protein snack we've tested. The sweetness comes from steviol glycosides, a plant-derived sweetener, rather than sugar alcohols like maltitol or erythritol, which can cause digestive issues for some. The trade-off for such a clean list is often taste or texture, but the use of cocoa, almonds, and walnuts provides a natural flavour base. It's a strong choice for ingredient-conscious shoppers who still want a significant protein hit without a long list of E-numbers.

Frequently asked questions
- Is this bar filling enough for a snack?
- Yes, it's very filling for its size. The combination of 20g of protein and a very high fibre content makes it far more satiating than a typical snack bar. These two components slow down digestion and contribute to a feeling of fullness, which is unusual for a bar with only 158 calories. We'd grab it to tackle an afternoon slump without derailing your macros.
- Should I eat this before or after a workout?
- It's best suited for after a workout. The 20g of high-quality whey and milk isolate protein is ideal for muscle repair and recovery. While you could eat it beforehand, the high fibre content might feel heavy during an intense session for some people. We think it's a perfect gym-bag staple for a convenient post-training refuel.
- How does this Brownie flavour compare to others in the Fibre Boost range?
- It sits very consistently within the brand's lineup. Most Fibre Boost bars share a similar nutritional philosophy of high protein, high fibre, and very low sugar. Compared to the Caramel Honey Macadamia version, for example, the protein and sugar are almost identical. Your choice will likely come down to flavour preference rather than any significant nutritional difference.
- What is the texture of the bar like?
- Expect a dense, chewy, and substantial texture. As a 'raw, cold pressed' bar, it's not baked or light like a cookie. It's a solid, satisfying chew, with some crunch from the included almonds and walnuts. This gives it a real-food feel that many highly processed bars lack. If you prefer a soft or crispy bar, this might not be for you.
- Why does this bar score so well for protein?
- Our Protein Score is heavily weighted towards protein-per-calorie, a measure of efficiency. This bar delivers an impressive 12.6g of protein for every 100 calories, placing it among the most efficient snacks we've tested. The 20g of protein per serve also firmly meets the benchmark for a dedicated protein bar, not just a snack with a minor protein boost.
