Rankings
- #1. Muscle Nation Crisp Protein Bar Choc Brownie - Protein Score 9.5/10 · Clean Score 7.4/10 · 20.4g/serve
This bar takes the top spot with a Protein Score of 9.5/10, driven by a seriously good protein hit. Landing 20.4g of protein per serve, it sits well above what many competitors offer the supermarket shelf. The 'Crisp' in the name isn't just for show, delivering a crunchy, layered texture that stands out from the typically dense and chewy bars in this aisle. The nutrition is rounded out with a low 3g of sugar per 100g. While its Clean Score of 7.4/10 reflects a list of 5 additives, it's a reasonable trade-off for the texture and flavour. For a convenient and high-protein snack that actually satisfies, the Muscle Nation Crisp bar is our pick for a post-gym refuel or a desk-drawer staple.
- #2. BSc Soft Protein Bar Banana Chocolate - Protein Score 9.4/10 · Clean Score 6.6/10 · 16.2g/serve
With a Protein Score of 9.4/10, the BSc Soft Protein Bar Banana Chocolate sits just a fraction behind our top-ranked Muscle Nation Crisp Protein Bar Choc Brownie. The numbers are strong, delivering 16.2g of protein per serve with 3.9g of sugar per 100g. It's a solid performer that gets the core job of a protein bar done without a huge sugar hit. The trade-off is the additive load. A Clean Score of 6.6/10 is driven by 6 additives on the label, which is a lot for a top-ranked bar. If you're chasing clean ingredients, skip it. The BSc High Protein Bar Cookies & Cream is a far better choice from the same brand. This bar is for those focused purely on protein and sugar macros, but the ingredient list is a compromise.
- #3. BSc High Protein Low Carb Bar Dark Choc Cookie - Protein Score 9.4/10 · Clean Score 6.7/10 · 19.6g/serve
BSc's High Protein Low Carb Bar in Dark Choc Cookie earns its spot near the top with a Protein Score of 9.4/10. It delivers a solid 19.6g of protein per serve, putting it right in the mix with the best protein bars we've analysed. While it doesn't quite catch the category leader, Muscle Nation Crisp Protein Bar Choc Brownie, its protein-to-calorie ratio is undeniably strong. The catch is the ingredient list. A Clean Score of 6.7/10 is the result of 8 additives, a busy formula that includes multiple sweeteners and emulsifiers. For anyone wanting a cleaner label, this is a clear 'skip it'. The brand's own BSc High Protein Bar Cookies & Cream is a much better choice on that front. This bar is for those chasing protein numbers, but others will find cleaner options.

Editorial deep dive
The protein bar shelf at Coles and Woolworths is a two-brand town, dominated almost entirely by Muscle Nation and BSc. While both brands land punches at the top of our rankings, they take very different approaches to formulation, creating a real trade-off for shoppers between a clean ingredient list and sheer protein density. Our top pick is the Muscle Nation Crisp Protein Bar Choc Brownie, earning a Protein Score of 9.5. It strikes balance, delivering 34.1g of protein per 100g with a relatively modest list of five additives. The 'Crisp' format is a welcome change from the dense, chewy texture that defines much of the category, making it a more satisfying desk snack or gym bag staple. The story gets complicated just below the top spot. The next two highest-scoring protein bars are from BSc, but both come with a heavy additive load. The BSc Soft Protein Bar Banana Chocolate carries six additives, while the BSc High Protein Low Carb Bar Dark Choc Cookie contains eight. On the numbers, we say skip them. The cleaner profile of the Muscle Nation Crisp Protein Bar Choc Brownie makes it the smarter pick. If your only goal is maximum protein per gram, then the BSc High Protein Bar range leads the category. The Salted Caramel flavour packs a massive 52.7g of protein per 100g, a figure none of the other protein bars we scored come close to. The catch is that these bars rely on sugar alcohols like maltitol to keep sugar content low, which can be a gut comfort issue for some people. It's a classic trade-off: high protein, low sugar, but with potential digestive consequences. Ultimately, the Muscle Nation Crisp Protein Bar Choc Brownie is the standout. It delivers a strong protein hit without the extensive additive list seen in its closest competitors, securing the top rank without forcing a compromise on ingredient quality. It's the one to grab first.

Stick to the High Protein Bar range for a serious protein hit. The BSc High Protein Bar Cookies & Cream is a standout with 52.4g of protein per 100g and just 1.2g of sugar per 100g. While the Soft Protein and Low Carb bars aren't bad, they don't compete with the top on pure stats. You can grab any of these on your regular grocery run.

Muscle Nation goes head-to-head with BSc in the protein bar aisle, and on overall Protein Score, it's a coin flip. This Aussie brand is a massive presence at Coles and Woolworths, with almost its entire lineup available on supermarket shelves. While BSc edges it on lowest sugar and cleanest ingredients, Muscle Nation snags the highest single. Across the range, performance varies wildly. The lineup averages 30.8g of protein and 6.0g of sugar per 100g, but the numbers shift dramatically between products. The Muscle Nation HIGH PROTEIN BAR - Choc Honeycomb is a strong pick pick across the category, packing 43g of protein per 100g. At the other end, the Cheesecake Protein Bar Zesty Lemon drops to just 24.2g of protein per 100g while carrying 10.3g of sugar per 100g.

The Muscle Nation HIGH PROTEIN BAR - Choc Honeycomb is the clear winner, earning the top Protein Score in our analysis. The lower-protein Cheesecake and Custard bars often carry more sugar and don't deliver the same nutritional punch, so always check the label before you buy.
