Overview
The protein bar shelf is a real mixed bag, with chewy, multi-layered bars sitting next to simpler, wholefood-style options. Our top pick, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, shows that a simple approach is often best. It earns its place with a clean whey isolate base, just 0.4g of sugar per 100g, and an ingredient list you can actually read. Fibre Boost dominates the top of our rankings for a reason. Their raw, cold-pressed method stands apart from the baked and layered bars from brands like BSc and Muscle Nation, which often rely on sugar alcohols like maltitol. With just one additive, the leading Fibre Boost bars earn a Clean Score of 9.9, making them a standout for anyone trying to minimise gut-upsetting ingredients. While BSc's High Protein Bar Salted Caramel leads the category for pure protein density at a huge 52.7g per 100g, it comes with a longer list of ingredients. For a bar that balances high-quality protein with clean profile, the choice is clear. If you're grabbing one bar off the shelf at Coles or Woolworths, make it the Fibre Boost.
Editorial deep dive
The protein bar shelf is a minefield. Some are genuinely useful snacks for a post-gym refuel or a desk drawer emergency, while others are just chocolate bars in disguise. Our analysis shows a clear winner that cuts through the marketing fluff, with the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip claiming the top spot. It earns a near-perfect Protein Score of 10.0, a result mirrored by its sibling flavours that dominate the top of our rankings. What sets the Fibre Boost range apart is its clean and simple approach. The leader earns a Clean Score of 9.9 thanks to a short ingredient list based on whey protein isolate, almonds, and cocoa, with just one additive. It keeps sugar low at just 0.4g per 100g, a fraction of the category average of 7.6g per 100g. This is achieved without resorting to the sugar alcohols like maltitol or erythritol that are common in this aisle and can cause digestive grief for many people. Of course, there are trade-offs. While Fibre Boost is our top-ranked pick, it doesn't lead on pure protein density. That title goes to the BSc High Protein Bar Salted Caramel, which packs a massive 52.7g of protein per 100g. To achieve that figure and the layered, crunchy textures found in many BSc, Muscle Nation, or Quest bars, you're typically looking at a more complex formula involving soy protein crisps, hydrolysed collagen, and sweeteners. Ultimately, the choice comes down to what you prioritise. The protein bar shelves at Coles and Woolworths are mostly filled with options from Fibre Boost, BSc, and Muscle Nation, each representing a different philosophy. If you want maximum protein per gram and don't mind a longer ingredient list with sugar alcohols, there are denser options available. But for a clean, effective, and gut-friendly protein bar that nails the fundamentals, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip is the clear standout and the one we'd grab first.

Go BSc for maximum protein, but pick Quest for a cleaner, lower-sugar option.
- How does ProteinScore rank protein bars?
- Our Protein Score is a 0-10 ranking that measures the nutritional quality of a protein bar. The score is primarily driven by the amount of protein per 100g and per serve, rewarding products that deliver a significant protein dose. However, we balance this against other factors, penalising bars that are excessively high in calories or sugar for the protein they offer. A high Protein Score indicates a bar is genuinely protein-focused, not just a confection with a sprinkle of protein.
- Which protein bar has the most protein?
- The protein bar with the highest protein content in our analysis is the BSc High Protein Bar Salted Caramel, which contains 52.7g of protein per 100g. Several other flavours in the BSc High Protein range, including White Choc Raspberry and Cookies & Cream, also hit this category-leading figure. This is substantially higher than the category average of 30.1g of protein per 100g, making this range the top pick for anyone prioritising maximum protein density.
