20.2g protein per serve · 248 cal · 1.7g sugar · 278mg sodium · 60g serve.
Overview
This is a texture-first protein bar, plain and simple. Where many bars in the aisle are dense, chewy blocks, Muscle Nation goes for crunch, using soy protein crisps to deliver a lighter, more snack-like bite. It feels more like a chocolate bar than a functional recovery product, which for many shoppers is exactly the point. The nutritional profile is stronger than the typical protein snack we track, packing 33.6g of protein per 100g against a category average of 27.1g. That translates to a solid 20.2g of protein in a single 60g bar, putting it squarely in the dedicated protein bar camp, not just a snack with a bit of protein sprinkled in. Compared with the brand's Crisp Protein Bar Choc Brownie, this peanut butter version has fractionally less protein and sugar, showing a consistent formula across the Crisp lineup. The protein comes from soy isolate, not the whey more common in powders. Sweetness is handled by maltitol (965) and steviol glycosides (960), which keeps the sugar figure down to just 1.7g per bar but may not suit everyone. Ultimately, this bar lands as a convenient, texture-driven option you can grab at the supermarket. We see it as a smart desk-drawer snack to beat an afternoon slump or a more satisfying alternative to a standard chocolate bar when you want the extra protein without a huge sugar load.
Protein Score: 9.2/10
This bar lands as a respectable, if not top-tier, protein option for the supermarket aisle. It clears the 20g-per-serve hurdle that separates serious protein bars from casual snacks, earning a Protein Score/10. That protein density puts it comfortably ahead of the category average. The 20.2g of protein comes from a soy-based blend, primarily soy protein crisps and isolate. While effective, soy protein isn't always as sought-after as whey for some post-workout shoppers, but it delivers the numbers here and contributes to the bar's signature crunchy texture. For a single 60g bar, the protein-per-calorie return is solid. It's a legitimate choice for a post-gym refuel or for anyone looking to hit a specific daily protein target without resorting to another shake. It outclasses standard muesli bars and many other so-called protein snacks with ease.
Clean Score: 7.2/10
Muscle Nation's bars tend to prioritise macros and texture over a short ingredient list, and this one is no exception. With 26 ingredients, including multiple emulsifiers and sugar alcohols, it's a moderately processed product. This earns it a Clean Score/10, which trails the average for the protein snacks category. The list includes soy lecithin (322) and polyglycerol polyricinoleate (476) to keep the chocolate coatings smooth and stable. Sweetness comes from the sugar alcohol maltitol (965) and stevia, which keeps the final sugar count low but adds complexity. These are common tools used to make a high-protein, low-sugar bar taste good, but they move it away from a whole-food snack. The trade-off is clear: you accept a longer list of additives to get a crunchy, chocolate-coated bar that packs 20g of protein with less than 2g of sugar. For shoppers focused purely on macros and taste, it's a workable compromise. For those seeking a simpler, less-processed snack, there are cleaner options available.

Frequently asked questions
- Is the Muscle Nation Crisp Protein Bar stronger on the numbers?
- We can't say if it's stronger on the numbers for you specifically, but the data shows it's a high-protein snack with low sugar for its category in Australia. Each 60g protein bar contains 20.2g of protein and only 1.7g of sugar, which is a strong trade-off compared to a regular chocolate protein bar. However, it does contain 248 calories and a long list of 26 ingredients, including sugar alcohols like maltitol (965) and emulsifiers, so it's a more processed option. For 2026, it fits the bill as a smarter indulgence rather than a whole-food snack.
- Is the Muscle Nation Crisp protein bar good for muscle gain?
- We don't give nutritional advice, but the 20.2g of protein per bar is a significant contribution towards daily protein targets for muscle growth and repair in Australia. This amount is comparable to many dedicated post-workout protein bars. The protein source is primarily soy isolate, which is a complete protein. For best results in 2026, it's most effective when used as a convenient supplement to a balanced diet rich in whole-food protein sources, rather than as a primary recovery tool.
- How much protein is in a Muscle Nation Crisp protein bar?
- A single 60g Muscle Nation Crisp Protein Bar in Chocolate Peanut Butter flavour contains 20.2g of protein. This is a substantial amount for a single snack bar, putting it well into the range of a dedicated protein product rather than just a snack with some protein. Per 100g, the protein bar provides 33.6g of protein, which is significantly higher than the average for the protein snacks category we score. The protein comes mainly from soy protein crisps and soy protein isolate.
- Will the sugar alcohols in Muscle Nation Crisp protein bars cause stomach issues?
- This protein bar contains the sugar alcohol maltitol (965), which is used to provide sweetness without the calories of sugar. For some people, particularly when consumed in large amounts, sugar alcohols like maltitol can cause digestive discomfort such as gas, bloating, or a laxative effect. Sensitivity varies greatly between individuals. If you're new to products with sugar alcohols, you might consider starting with half a protein bar to see how you react before making it a daily snack.
- Muscle Nation Crisp Choc Peanut Butter vs Choc Brownie: which is better?
- Both protein bars are very similar, making the choice mostly about flavour preference. The data shows the Choc Brownie version has fractionally more protein, with 34.1g per 100g compared to 33.6g in the Chocolate Peanut Butter protein bar. The sugar content is almost identical. Both use a similar soy protein base and have long ingredient lists with multiple additives. Ultimately, the nutritional difference is negligible, so we'd suggest picking the one whose flavour profile you enjoy more.
- Is the Muscle Nation Crisp protein bar filling?
- With 248 calories and 11.5g of fibre per 100g, the Muscle Nation Crisp protein bar is more satiating than a standard chocolate protein bar. The combination of high protein (20.2g per serve) and fibre helps to promote a feeling of fullness, making it a decent option to curb afternoon hunger. However, it's designed as a snack and isn't substantial enough in calories or overall nutrition to be considered a meal replacement on its own.
- Where can I buy Muscle Nation Crisp protein bars in Australia?
- Muscle Nation Crisp Protein Bars are catalogued in the snack aisle at major Australian supermarkets like Coles. You may also find them available for purchase directly from the brand's own website or at various supplement retailers. Stock can vary by store location, so it's always a good idea to check the retailer's website for local availability.
