Editorial deep dive
Our analysis of protein bars reveals a complete takeover by one brand. The top spot is claimed by Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, earning a perfect Protein Score of 10.0. It's not just a solo victory; the entire top of the rankings is a clean sweep by Fibre Boost, showcasing a dominant performance on protein density and ingredient quality. The numbers explain why. The winning Choc Choc Chip flavour delivers 34.8g of protein per 100g with just 0.4g of sugar per 100g. This ratio is built on a base of whey and milk protein isolates, using soluble corn fibre instead of the sugar alcohols like maltitol or erythritol that are common in this aisle. For anyone sensitive to those sweeteners, this is a significant difference. This focus on a cleaner profile is reflected across the entire Fibre Boost range. Most of their bars contain only a single additive and use stevia for sweetness, which is a far cry from the lengthy ingredient lists we often see. This earns the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip a Clean Score of 9.9, making it one of the cleanest protein bars we have scored. The main point of difference for shoppers will be the texture. These are "raw, cold pressed" protein bars, meaning they are dense and chewy, not soft-baked or crunchy like many alternatives. The experience is more akin to a wholefood bar than a confectionary item. This isn't a negative, but it's a key factor in whether you'll come back for a second purchase. Ultimately, the decision here is less about choosing a brand and more about finding your favourite Fibre Boost flavour. If you're after maximum protein with minimal sugar and a clean ingredient list, start with the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip. It sets the standard for what a nutritionally focused protein bar can be.

- How does ProteinScore rank protein bars?
- We rank protein bars using our Protein Score, a 0-10 metric calculated from the nutrition label.
