Lowest Sugar Protein Bars in Australia - Ranked 2026
The major protein bars in Australia, ranked by sugar per 100g, lowest first. The leaders barely register on sugar. The worst pack a hidden sugar hit.
113 products ranked. Updated 2026-06-13.
Overview
The protein bar shelf is a mess of trade-offs, but the top of our rankings is refreshingly simple. Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip is the standout across the 121 bars we scored, earning a Protein Score of 10.0. With a clean, whey-isolate base, just 0.4g of sugar per 100g and a top Clean Score of 9.9, it skips the artificial sweeteners and complex layers common in this category. Many other bars you'll spot at Coles and Woolworths focus purely on hitting a high protein number, often with a much longer ingredient list. While the BSc High Protein Bar Salted Caramel leads the category for density with 52.7g of protein per 100g, it relies on a more processed format and sweeteners. This is the main choice shoppers face: a simple, raw-pressed bar versus a multi-layered one loaded with sugar alcohols like maltitol. On the numbers, the decision is clear. If you want a straightforward bar that delivers a quality 20.9g of protein per serve without the complex additives, Fibre Boost is the one to grab. It proves that a higher protein count doesn't always make for a better bar.
The verdict
The protein bar aisle is a mess of sugar alcohols and filler ingredients, but Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip cuts through it all. It takes the top spot by delivering a genuine 20.9g of protein per serve with just 0.4g of sugar per 100g, lean profile. With only one additive on the label, it's about as clean as you can get for a pre-packaged bar, making it our clear pick for a simple, effective snack that fits any gym bag. If your only goal is maximum protein density, the BSc High Protein Bar Salted Caramel leads the category with an immense 52.7g of protein per 100g. This is a much heavier, more processed bar designed for a serious refuel, but it shows the trade-off you make for that extra protein. For most people, most of the time, the cleaner, more balanced profile of the Fibre Boost bar is the smarter grab-and-go choice.
Rankings
- #1. BC Snacks High Protein Bar 4 Pack Chocolate Brownie Crunch - Protein Score 10.0/10 · Clean Score 8.6/10 · 10.9g/serve
Protein Score 10.0/10. This is the cleanest, most efficient protein bar we have analysed. The Fibre Boost Raw Choc Choc Chip bar delivers 20.9g of protein per serve from a lean 243 calories per 100g. With sugar at a tiny 0.4g per 100g and only one additive on the label, it earns a near-perfect Clean Score of 9.9/10. The cold-pressed format means this isn't a soft-baked, layered bar, but rather a dense, raw-textured block that feels less processed. It sidesteps the usual sweeteners and fillers common in the category, making it a genuine post-gym refuel without the gut-busting extras. For anyone wanting maximum protein with minimal processing, this is the one to beat.
- #2. Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Hazelnut - Protein Score 10.0/10 · Clean Score 9.6/10 · 20.6g/serve
A perfect Protein Score of 10.0/10 puts this Choc Raspberry bar in a dead heat for first place, tying with the official leader, Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip. The numbers across the board, delivering 21g of protein per serve with just 0.4g of sugar per 100g. A Clean Score of 9.9/10, thanks to only one additive, confirms it's one of the cleanest protein bars we've analysed. The entire Fibre Boost range dominates the top of our rankings, and this flavour is no different. It matches the category leader on every key metric, so the decision between them really just comes down to personal taste. If you're after a lean, high-protein bar and prefer a fruit flavour over straight chocolate, this is an equal-best pick.
- #3. Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Almond - Protein Score 10.0/10 · Clean Score 9.9/10 · 20.4g/serve
With a perfect Protein Score of 10.0/10, this Choc Mint flavour is numerically identical to our top pick, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip. The stats are elite across the board, delivering 21.3g of protein per serve with just 0.4g of sugar per 100g. It also earns Clean Score of 9.9/10, thanks to having only one additive on the label. The entire Fibre Boost lineup performs well in our analysis, and this bar is no exception. At 244 calories per 100g, it's one of the leanest protein bars we've scored while still providing a substantial protein hit. If you're a fan of choc mint, there's no nutritional trade-off here; you're getting the same top profile as the leader.

Editorial deep dive
The protein bar shelf is a study in contrasts. On one side, you have clean, cold-pressed bars made with recognisable ingredients. On the other, you have multi-layered, soft-baked bars that push protein density to its limits using complex blends and sugar alcohols. Our analysis shows one brand, Fibre Boost, absolutely dominates the top of the rankings by keeping its ingredient list short and its protein quality high. Our number one pick is the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, earning a perfect Protein Score of 10.0. This bar delivers 34.8g of protein per 100g with low 0.4g of sugar per 100g. Its Clean Score of 9.9 reflects a simple formula with just a single additive. The entire Fibre Boost lineup follows this blueprint, using a whey and milk protein base with nuts and natural flavours, making it a straightforward choice for anyone wanting to avoid a long chemical list. For shoppers chasing the absolute highest protein number, the trade-off is clear. The BSc High Protein Bar Salted Caramel leads the category for density, packing an enormous 52.7g of protein per 100g. To achieve this, it relies on a blend including collagen peptides and soy protein, along with sweeteners like maltitol. This isn't a bad thing, but it's a different product for a different goal, built for maximum protein delivery rather than minimal processing. It's also worth watching out for products that are really just snack bars in disguise. Some options on the shelf, like the Atkins Endulge Bar Dark Chocolate with only 4.9g of protein per 100g, don't offer a meaningful protein top-up. Always check the protein content per bar to make sure it aligns with what you need, whether it's a quick desk snack or a more substantial post-gym refuel. So, the decision at the supermarket aisle comes down to your priority. If you want the most protein possible per gram, brands like BSc and Musashi deliver. But for a clean, effective protein bar that doesn't compromise on ingredients, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip is the one to grab first. You'll spot the range at Coles and Woolworths.
Brand-by-brand notes
Fibre Boost
Fibre Boost is an Australian brand that goes all-in on raw, cold-pressed protein bars with clean ingredient lists. They have one of the biggest ranges we've scored, with 26 different flavours flooding our index. You won't find these doing a weekly shop, though, as they aren't stocked in the major supermarkets. The performance across the entire range is remarkably consistent. Protein averages a solid 34.6g per 100g, but the sugar content is the real standout, averaging just 1.4g per 100g. Our #1 pick, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, leads the category with only 0.4g of sugar per 100g. It also earns a near-perfect Clean Score of 9.9, a figure matched by many other bars in the lineup. It's hard to make a bad choice here. The Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip gets the official nod, but with so many flavours tied on ultra-low sugar and top clean scores, you can pick based on preference. Just remember to plan ahead, as you'll need to order these direct from the brand's website or find them at a specialty retailer.
Quest
Quest is a big name from the US that has become a fixture in Australian supermarkets. Their whole deal is creating protein bars that taste like dessert treats while keeping sugar extremely low. You'll find the core range of 4 protein bars we've scored in the aisles at Coles and Woolworths, making them an easy grab during the weekly shop. On the numbers, Quest bars are consistent performers. The range averages a solid 34.5g of protein per 100g, though this sits a fair way behind the category-best BSc High Protein Bar Salted Caramel at 52.7g per 100g. Sugar is kept very low at an average of 1.4g per 100g, with the Quest Protein Bar S'mores leading their pack at just 1.1g of sugar per 100g. This is achieved using a blend of artificial sweeteners like sucralose and erythritol. If you're after a reliable, high-protein bar and don't mind artificial sweeteners, Quest is a dependable pick. They don't hit the protein highs of BSc or the ultra-low sugar marks of our top pick, Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, but they deliver a balanced performance across the board. For a straightforward option that's easy to find, they're hard to fault.
BC Snacks
BC Snacks is a supermarket staple, with its range of 13 protein bars found across Coles and Woolworths. The brand doesn't play in the specialty supplement space, instead focusing on convenient, single-serve bars for the everyday grocery shopper. Their lineup covers both whey-based and plant-based formulas, aiming for broad appeal on the shelf. On the numbers, the BC Snacks range is a mixed bag. The brand averages a reasonable 26.8g of protein and 5.4g of sugar per 100g across the bars we've scored. However, there's a huge performance gap between their best and worst. The standout is the High Protein Bar Dark Chocolate Almond with 28.5g of protein per 100g and just 2.2g of sugar per 100g. At the other end, the Plant Protein Bar Dark Choc Coconut lands with a weak 16.1g of protein per 100g and a massive 21.4g of sugar per 100g. This inconsistency means you need to read the label carefully. The BC Snacks High Protein Bar Dark Chocolate Almond is a decent pick if you're grabbing one during your weekly shop. We'd steer clear of the Plant Protein Bar Dark Choc Coconut, as its high sugar and low protein content puts it well behind cleaner, more effective options on the same shelf.
BSc
BSc is a staple of Australian sports nutrition, with a huge presence on supermarket shelves. You'll find their extensive lineup of 19 protein bars at Coles and Woolworths, making them one of the most accessible brands for a quick protein fix during the weekly shop. Their range is broad, covering everything from ultra-dense bars to softer, more treat-like options. The performance across the BSc range varies significantly. Their High Protein Bar lineup is a standout for protein density, with the Salted Caramel flavour packing a category-leading 52.7g of protein per 100g. This is a massive number that few others can match. In contrast, their Soft Protein Bar range, including collaborations like the BSc x Chupa Chups Soft Protein Strawberry Cream, sits much lower at 29.5g of protein per 100g. While sugar is kept reasonably low across both, the protein difference is stark. For shoppers, the choice depends entirely on your goal. If you want the most protein possible, the BSc High Protein Bar Salted Caramel is one of the strongest performers in our entire index and is the one to grab. If you're after a softer texture and the protein number is less critical, the Soft Protein Bars are a decent alternative. Just know you're trading a significant amount of protein for that different eating experience.
Muscle Nation
Muscle Nation is a well-known Aussie brand, starting in apparel before moving into sports nutrition. While they sell direct, their protein bars have become a fixture in major supermarkets. Of the 15 protein bars we have analysed, 14 are easily found at Coles or Woolworths, making them one of the most accessible brands on the shelf. The performance across the range is inconsistent. On average, their bars deliver 30.8g of protein and 6.0g of sugar per 100g, which. However, the gap between their best and worst is wide. The Muscle Nation Crisp Protein Bar Choc Brownie leads their lineup with 34.1g of protein per 100g and just 3g of sugar per 100g. At the other end, the Muscle Nation Cheesecake Protein Bar Zesty Lemon drops to 24.2g of protein per 100g and climbs to a much higher 10.3g of sugar per 100g. This makes reading the label crucial. For a solid post-gym refuel, the Crisp Protein Bar Choc Brownie is the clear winner from their range. We'd give the Cheesecake bars a miss, as the lower protein and higher sugar content don't stack up as well. Since you'll find most of the range in the supermarket aisle, it's easy to make the switch on your weekly shop.
Noshu
Noshu is an Australian brand built on a low-sugar promise, famous for its baking mixes and supermarket doughnuts. They've carried that approach over to the two protein bars we've scored, positioning them as convenient snacks you can grab during the weekly shop. You'll find them easily in the health food aisle at major supermarkets like Coles and Woolworths. On the numbers, the protein bars don't quite stack up against the category's heavy hitters. The range averages a modest 21.9g of protein and a relatively high 8.6g of sugar per 100g. Of the two, the `Noshu Protein+ Fibre Pro Bars Choc Malt` is the stronger performer, with 23.7g of protein per 100g and 6.6g of sugar per 100g. This is a long way off the protein density of market leaders like BSc, which push past 50g per 100g. While convenient, Noshu's protein bars are more of a casual snack than a serious performance product. If you're chasing maximum protein or minimal sugar, there are much stronger options available. For near-zero sugar, the category-leading `Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip` is the clear winner. Noshu is an easy find, but it's not a standout in this competitive field.
NOWAY
NOWAY is the protein bar line from Australian supplement company ATP Science, and their entire range is built around collagen protein. This is a genuine point of difference in a market saturated with whey and soy. You won't find these bars in the major supermarkets; all 5 of the protein bars we've scored are sold directly through their website or via specialty supplement stores. The brand's performance is mixed. Protein content. averaging 32.8g per 100g across the range. The sugar, however, is a real problem, sitting at an average of 11.4g per 100g. That's a huge gap compared to the category's leanest bars. The standout is the Mint Candy Cane Collagen Fusion Bar with 34.9g of protein per 100g, while the Collagen Marshmallow Bar in Vanilla is the weakest, with 12.2g of sugar per 100g. If you're specifically after a collagen-based bar, NOWAY is one of the only options out there. But for everyone else, the high sugar makes them a tough sell against cleaner, more protein-dense competitors. If you do grab one, make it the Mint Candy Cane flavour for its slightly better numbers, and remember you'll need to order it online rather than picking it up with your groceries.
Atkins
Atkins is a global brand built on a low-carbohydrate philosophy, and its bars stick to that script. The range is less about fuelling athletes and more about providing low-sugar alternatives to conventional snacks. You'll find the 3 protein bars we've scored in the health food aisle at major Australian supermarkets, sitting right there in Coles and Woolworths. On the numbers, the "protein bar" label feels like a stretch. The range averages a very low 11.0g of protein per 100g, which doesn't come close to the heavy hitters in this category. The best of the bunch is the Atkins Endulge Bar Chocolate & Coconut with 13g of protein per 100g. The weakest, the Atkins Endulge Bar Dark Chocolate, delivers only 4.9g of protein per 100g, making it more of a low-sugar chocolate square. If you're hunting for a high-protein bar for post-workout recovery, look elsewhere. The protein content here is just too low to be effective. However, if your goal is simply to find a low-sugar treat at the supermarket that satisfies a sweet craving without the sugar load, then Atkins delivers on that specific promise. Just manage your expectations on the protein front.
Sam's Pantry
Sam's Pantry is the in-house brand for Woolworths, covering a huge range of grocery items from baking mixes to snacks. As a private label, you'll only find these protein bars the supermarket shelves, making them an exclusive supermarket grab. We've analysed the three protein bars in their lineup, which are clearly aimed at the casual shopper, not the dedicated gym-goer. The nutritional profile across the range is more aligned with a snack bar than a dedicated protein product. The brand averages a modest 21.2g of protein per 100g, which sits well below the category leaders. The sugar content tells the difference, with an average of 22.0g per 100g. The Sam's Pantry Protein Crisp Bars Dark Choc Caramel lands with 21.1g of protein per 100g but carries a hefty 21.2g of sugar per 100g, blurring the line between a protein bar and a chocolate bar. If you're after a quick grab during your grocery run, these bars offer a slight protein edge over standard confectionary. But for anyone serious about their nutrition, the sugar load is a significant drawback. We'd suggest looking elsewhere in the aisle, as the high sugar makes these a pass for us. You can find much cleaner and more protein-dense bars without leaving the supermarket.
Musashi
Musashi is one of the original Aussie sports nutrition brands, on the scene since 1987 and now part of the Vitaco Health group. They're a familiar sight in supermarkets, with all 7 of the protein bars we've scored readily available at Coles and Woolworths. Their branding is all about performance, but the numbers across their bars tell a story of inconsistency. Across the range, Musashi's protein bars average 31.3g of protein per 100g. The catch is the sugar, which averages a fairly high 9.3g per 100g. There's a big difference between their best and worst performers. The Musashi Protein Crisp Choc Brownie leads the brand's lineup with 34g of protein per 100g and 6.3g of sugar per 100g. At the other end, the Musashi Protein Wafer Bar White Chocolate has just 25g of protein per 100g and a hefty 11.7g of sugar per 100g. This is a brand where you absolutely need to read the label before you buy. If you're grabbing a Musashi bar from the supermarket shelf, the Protein Crisp Choc Brownie is the one to go for based on the numbers. We'd give the Protein Wafer Bar a definite miss, as its lower protein and higher sugar content just don't stack up against the better options available in the same aisle.
Carman's
Carman's is an Australian staple, a familiar face in the supermarket aisle known more for its muesli and oat-based snacks. Their expansion into protein bars makes sense, using their brand recognition to offer convenient options. You'll find all 13 of the protein bars we've scored right there during your weekly shop at major supermarkets, sitting alongside their core range. On the numbers, the Carman's range is a mixed bag. The average protein across their bars is 27.3g per 100g, but the average sugar is a very high 19.9g per 100g. This creates a huge performance gap within their own lineup. This is a brand where you need to read the label carefully. While convenient to grab on a supermarket run, many of their protein bars carry a sugar load that puts them closer to a standard snack bar. If you're set on Carman's, the Plant Protein Bar Raspberry Pistachio is the clear pick of the bunch.
Go Natural
Go Natural is a familiar Aussie brand, holding down shelf space in the snack aisle for years. The company is Australian-owned and its products are easy to find during a regular supermarket shop at Coles or Woolworths. While they market some products as protein bars, their focus is clearly on wholefood ingredients like nuts and seeds, not on hitting high protein targets. On the numbers, the Go Natural range falls well short of what we look for in a protein bar. The brand averages a very low 8.1g of protein per 100g and a massive 36.3g of sugar per 100g. Their best effort, the Go Natural Choc Salted Caramel Bar, only manages 12.3g of protein per 100g. At the other end, the Go Natural Macadamia Dream Bar delivers just 4.9g of protein per 100g alongside 39.1g of sugar per 100g, putting it closer to a standard confectionery bar. For anyone chasing a meaningful protein hit, this is a brand to skip. The protein content is simply too low and the sugar load is far too high to compete with dedicated protein brands in this category. If you're stuck and it's between one of these and a standard chocolate bar, it might be the slightly better pick, but it's not a functional protein product. You'll find much stronger options elsewhere on the supermarket shelf.
Frequently asked questions
- What is the best protein bar in Australia 2026?
- The best protein bar we've scored in Australia for 2026 is the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, which earns a perfect Protein Score of 10.0. It leads a field of over 120 protein bars by combining a strong protein base with clean ingredient list. On the numbers, it also has the highest Clean Score of 9.9 and contains just 0.4g of sugar per 100g, making it our top pick overall.
- Is BSc a good protein bar brand?
- We don't give nutritional advice, but the data shows BSc makes some of the most protein-dense bars in Australia for 2026. Their High Protein Bar Salted Caramel is the category leader for protein content, with 52.7g of protein per 100g. While their Protein Scores are strong, their reliance on artificial sweeteners and additives means they don't score as well on our Clean Score metric compared to brands like Fibre Boost.
- Is Muscle Nation a good protein bar brand?
- We can't say if it's a good brand for you specifically, but on the numbers, Muscle Nation produces high-protein bars that rank well for protein density. For example, their HIGH PROTEIN BAR in Cookies & Cream flavour contains 43.9g of protein per 100g. The trade-off is that their bars often contain added sugar and a longer list of ingredients, which holds them back from the top spots on our rankings.
- Are protein bars good for weight loss?
- Protein bars aren't a weight-loss product on their own, but they can support your goals if you choose wisely. A good protein bar can help with satiety, keeping you fuller for longer. On the numbers, a bar like the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip offers 34.8g of protein per 100g with only 0.4g of sugar per 100g, fitting into a calorie-controlled diet better than many alternatives.
- How much protein is in a Quest Protein Bar?
- The protein content in Quest Protein Bars is consistently high, sitting around 35g of protein per 100g. Specifically, the Cookies & Cream flavour contains exactly 35g of protein per 100g, as does the Choc Chip Cookie Dough flavour. This makes them a very dense source of protein compared to many other options available on shelves.
- How does ProteinScore rank protein bars?
- Our Protein Score is a 0-10 rating that measures two key things from the nutrition label. First, we look at protein density, which is the amount of protein you get per calorie, rewarding leaner protein bars. Second, we assess protein quality by looking at the sources listed in the ingredients. We also run a separate Clean Score, which rates protein bars based on their use of artificial sweeteners, additives, and added sugars.
- BSc vs Muscle Nation protein bars: which is better?
- Looking at the data, BSc and Muscle Nation both deliver very high protein content, but BSc generally has the edge on raw protein density. The BSc High Protein Bar range peaks at 52.7g of protein per 100g, while the Muscle Nation HIGH PROTEIN BAR range tops out around 43.9g per 100g. Both brands use complex ingredient lists with sweeteners and additives. For the highest possible protein hit, the numbers point to BSc.
- What is the best low sugar protein bar?
- We can't give specific dietary advice, but on the numbers, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip is the lowest-sugar option we've scored, with just 0.4g of sugar per 100g. In fact, the entire Fibre Boost range is low in sugar, with many flavours like Choc Mint, Cereal Milk, and Birthday Cake all sharing that same minimal 0.4g per 100g figure, making the whole lineup a standout choice.
