Overview
This bar sits at the cleaner, more functional end of the protein snack aisle, sidestepping the long ingredient lists and higher sugar loads common in the category. With 33.6g of protein per 100g, it is significantly more protein-dense than the typical 27g/100g bar we see. Compared with the Banana Split flavour in the Fibre Boost range, this Black Forest version has a touch more protein and a fraction less sugar. It's a minor difference, but shows the brand's consistency in delivering high-protein, low-sugar bars across its lineup. We find this pattern holds true for most of the flavours we've looked at. The ingredient list is where this bar really makes its case. We're looking at a base of whey and milk proteins, with soluble corn fibre doing the heavy lifting on satiety, not a list of sugar alcohols. Real cherries and cocoa provide the flavour, sweetened with stevia. It's a simple, effective formula for a market crowded with complex ones. This isn't a light, fluffy chocolate bar; it's a dense, satisfying, cold-pressed bar designed to deliver a protein hit with minimal sugar and calories. It's built for the desk-drawer or gym bag, for someone who reads the label and wants every ingredient to earn its place.
Protein Score: 10.0/10
Fibre Boost consistently delivers some of the highest-scoring bars we've tested, and this Black Forest flavour fits the pattern. The 20.2g of protein in a single 60g bar is a serious contribution for a snack this size, earning a Protein Score/10. It's a standout performer in a crowded field. Stack this against a standard muesli bar with its 2-5g of protein, and the difference is night and day. This bar delivers a protein load comparable to dedicated recovery bars, but in a much smaller, sub-150 calorie format. The protein-per-calorie efficiency is the key metric here, and at 13.5g of protein per 100 calories, it's strong. The protein comes from a blend of whey and milk isolates, a quality source that's easily digestible for most. This isn't a snack with a sprinkle of protein; it's a protein-first product for someone tracking their macros closely or needing a substantial post-workout refuel on the go.
Clean Score: 9.6/10
Is it possible to get a high-protein bar without a long list of artificial ingredients? This bar suggests the answer is yes. With just 10 ingredients and no artificial sweeteners, colours, or preservatives, it achieves a Clean Score/10. The score reflects a very short ingredient list, less than half the length of the category average. The only additive is a natural sweetener, Steviol Glycosides, used instead of the sugar alcohols or artificial sweeteners that populate many rival bars. This is as close to a whole-food bar as you'll find in this functional category. For shoppers who scrutinise labels for numbers they don't recognise, this bar offers a clean slate. The trade-off for such a simple formula is often taste or texture, but the cold-pressed format and use of real cocoa and cherries deliver a satisfying chew without feeling overly engineered.

Frequently asked questions
- Is this bar better for pre- or post-workout?
- It's best suited for a post-workout snack. The 20.2g of protein from whey and milk isolates is ideal for muscle repair after exercise. While you could have it beforehand, the high fibre content might be uncomfortable for some during an intense session. For a quick and effective protein hit on the way home from the gym, we think it's a great option.
- How filling is this bar for only 149 calories?
- It's surprisingly filling for its size. The key is the massive 41g of fibre per 100g, which comes from soluble corn fibre. This slows digestion and promotes a feeling of fullness that punches well above its 149-calorie weight. It's a genuinely satisfying snack that can curb afternoon hunger, not just a sugary stop-gap.
- Can this protein bar replace a meal?
- No, this is a snack, not a meal replacement. At just 149 calories, it doesn't provide enough energy or the broad spectrum of nutrients that a complete meal would. While it's very high in protein and fibre for a snack, it's best used to supplement your diet between meals or after a workout. We'd grab it to tide you over, not to replace lunch.
- How does this Black Forest flavour compare to others in the Fibre Boost range?
- The nutritional profiles across the range are remarkably consistent. Compared to the brand's Banana Split flavour, for example, this Black Forest version has a fraction more protein and a little less sugar, but the differences are minor. The core formula of high protein, high fibre, and low sugar is the main event regardless of which flavour you choose. We'd suggest picking based on your flavour preference.
- What makes this a high-scoring protein bar?
- It scores highly on two key fronts: protein density and ingredient simplicity. The bar delivers an impressive 13.5g of protein for every 100 calories, which is far more efficient than most snacks. On the clean ingredient front, its list of just 10 ingredients and no artificial additives is well below the category average. It's this combination of strong macros and a clean deck that earns it top marks from us.
