Overview
The protein bar shelf is a busy place, but the top of our rankings is simple and clear. The Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip earns a perfect Protein Score of 10.0, backed by a near-perfect Clean Score of 9.9. This isn't your typical chewy, layered bar; it's a cold-pressed block of whey isolate, prebiotic fibre and nuts, with just one additive on the list. Fibre Boost's clean formula sweeps the top spots, but if your only goal is maximum protein density, BSc makes a compelling case. The BSc High Protein Bar Salted Caramel packs a massive 52.7g of protein per 100g, the highest across all 121 bars we analysed. The trade-off is a more complex formula common to brands like Muscle Nation and Quest, which often rely on sugar alcohols and longer ingredient lists to achieve that layered, crunchy texture. Ultimately, the choice comes down to your priorities. For a clean, straightforward protein hit that's easy on the gut, the Fibre Boost range is the standout pick and can be found on the shelves at Coles and Woolworths. If you prefer a confectionary-style experience and don't mind the extra additives, other brands deliver on that front. For us, the simple, high-quality formula wins out.
Editorial deep dive
The protein bar shelf is a minefield. Many are just dressed-up chocolate bars, loaded with sugar alcohols and additives that can leave you feeling worse than before. Cutting through that noise means looking for protein density and a clean ingredient list, a combination that's surprisingly rare. Our analysis shows one brand gets this balance right more consistently than any other. The Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip leads the category with a perfect Protein Score of 10.0 and an almost perfect Clean Score of 9.9. It delivers 34.8g of protein per 100g with just 0.4g of sugar per 100g and only one additive. The entire Fibre Boost lineup dominates the top ranks, proving a simple, cold-pressed bar can easily outperform more complex products. Of course, some shoppers are chasing maximum protein above all else. This is where you'll find protein-dense options like the BSc High Protein Bar Salted Caramel, which packs a huge 52.7g of protein per 100g. The trade-off is often a longer ingredient list featuring sugar alcohols like maltitol, which can cause digestive upset for some people. It's a classic split in the aisle: clean and simple versus dense and complex. Ultimately, the right bar depends on the job. A lighter bar with fewer calories is a great desk-drawer snack to get you through the afternoon. The heavier, more calorie-dense bars from brands like Muscle Nation or BSc are better suited for a post-gym refuel. You can spot the full range at Coles and Woolworths, so it's easy to compare labels firsthand. For us, the choice is clear. If you want a genuinely high-protein bar without the chemical baggage, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip is the one to grab. It sets the benchmark for what a clean, effective protein bar should be.

- How does ProteinScore rate protein bars?
- Our Protein Score is a 0-10 rating that measures the true protein utility of a protein bar based on the nutrition label.

We also analyse the ingredient list for the quality of the protein sources. This is combined with our Clean Score, which assesses the additive and sweetener load, to give you a complete picture of what you're buying.
