Overview
This Bubble Gum flavour sits at the top end of the Fibre Boost range for protein density. It edges out even the Choc Malt version with slightly more protein per 100g, while keeping sugar at virtually zero, continuing the brand's pattern of delivering high-performance bars. With 36g of protein per 100g, it's significantly denser than the 27g category average for protein bars. The ingredient list is also refreshingly short at just seven items, compared to the typical 22 we see in this aisle. This points to a less-processed approach, focusing on function over filler ingredients. The 'raw, cold-pressed' format creates a dense, chewy texture that isn't for everyone. While effective, the Bubble Gum flavour is a love-it-or-hate-it choice, moving it away from the usual chocolate and caramel crowd. We see this as a dedicated, functional snack for the gym bag or desk drawer when you need a protein top-up without the sugar or calorie load of more indulgent bars.
Protein Score: 10.0/10
This is one of the most efficient protein bars we have tested. The 21.6g of protein per 60g bar is strong on its own, but the difference is the protein-per-calorie density, which is among the best in the category and earns it a 10/10. It's a standout performer against the broader snack field. That 21.6g serve lands it squarely in dedicated protein bar territory, far beyond the 2-5g you might find in a standard muesli bar. It's built from a blend of whey and milk protein isolates, which are high-quality sources ideal for a post-workout window. This is a bar for someone who reads the nutritional panel first and sees flavour as a secondary bonus.
Clean Score: 9.9/10
Fibre Boost consistently uses a short, recognisable ingredient list, and this bar is no exception. With just seven ingredients and a single natural sweetener, it achieves a Clean Score/10. This reflects a commitment to minimal processing that's rare in the protein snack aisle. The list is anchored by prebiotic corn fibre, whey and milk proteins, and almonds. Sweetness comes from steviol glycosides (stevia), avoiding artificial sweeteners like sucralose or aspartame, and there are no added colours or preservatives. This is a very clean panel compared to the category average of 22 ingredients. The short ingredient list means you're getting a product that's closer to whole foods, without the gums or fillers used to create texture in other bars. The trade-off for this clean profile can sometimes be a denser, less candy-bar-like texture, which is exactly what you get here.

Frequently asked questions
- Is this bar better for pre or post-workout?
- It's best suited for post-workout. The 21.6g of protein comes from whey and milk isolates, which are digested relatively quickly to aid muscle repair after exercise. While you could have it pre-workout, the high fibre content might feel uncomfortable for some during an intense session. We'd save it for the 30-minute window after training for the best results.
- How filling is this bar for only 137 calories?
- It's surprisingly filling for its low calorie count. This is thanks to the massive 26.9g of fibre per bar, which is known to promote satiety and help you feel fuller for longer. The high protein content also contributes to that feeling of fullness. It's a great option to curb afternoon hunger without a big calorie hit.
- How does this compare to other bars in the Fibre Boost range?
- This Bubble Gum flavour has one of the highest protein contents in the range we've seen, at 36g per 100g. It's very similar to the brand's Choc Malt version, which has fractionally less protein but the same near-zero sugar content. Most bars in the lineup follow this same high-protein, low-sugar, high-fibre formula.
- Can this bar replace a small meal?
- We'd frame this as a substantial snack, not a meal replacement. While the protein and fibre are high, it's only 137 calories and lacks the broader micronutrient diversity of a balanced meal. It's perfect for bridging the gap between meals or for a post-workout refuel, but not to replace breakfast or lunch on a regular basis.
- What makes this bar score so well on your system?
- Its high scores come from its nutritional efficiency and clean formulation. The Protein Score reflects the huge 21.6g of protein for a low 137 calories. The Clean Score is based on the very short, seven-item ingredient list with no artificial sweeteners, colours, or preservatives, which is rare for the protein bar category.
