Overview
Chasing a low-sugar protein bar can feel like you're just trading sugar for a list of artificial sweeteners. Our analysis shows that's not always the case. The standout is Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, which leads the category with low 0.4g of sugar per 100g. The entire Fibre Boost range dominates the top of this leaderboard for a reason. What sets it apart is how it hits that number. Many bars on the shelves at Coles and Woolworths swap out sugar for sugar alcohols like maltitol or a stack of sweeteners. Fibre Boost manages it while earning a Clean Score of 9.9, thanks to a simple ingredient list. If you want a genuinely low-sugar bar without the chemical load, Fibre Boost is the clear pick.
The verdict
The Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip takes the top spot by a country mile. It lands the win with a tiny 0.4g of sugar per 100g, a number many bars loaded with sweeteners struggle to hit. Better yet, it does this cleanly with just one additive on the list, while still packing 20.9g of protein per serve. It's the clear choice for anyone trying to minimise both sugar and artificial ingredients in one go. If your main goal is pure protein density, the numbers point elsewhere. The BSc High Protein Bar Salted Caramel leads the entire category on that front, delivering a huge 52.7g of protein per 100g. It's a very different bar built for a different purpose, using sweeteners to keep its sugar low. So the choice is simple: grab the Fibre Boost bar for clean, low-sugar snack, or reach for BSc when getting the most protein possible is the only thing that matters.
Rankings
- #1. BC Snacks High Protein Bar Dark Chocolate Almond - Protein Score 10.0/10 · Clean Score 8.8/10 · 11.4g/serve
With a Protein Score of 10.0/10, this bar is the benchmark. It delivers a full 20.9g of protein per serve from just 243 calories per 100g, making it one of the most efficient protein bars we've analysed. The sugar is almost non-existent at 0.4g per 100g, and with only a single additive, it also secures a Clean Score of 9.9/10. The raw, cold-pressed format of the Fibre Boost bar sets it apart from the chewy, baked bars that fill the shelves. This is less of a treat and more of a purpose-built refuel, with numbers that back it up. For anyone tired of long additive lists and hidden sugars, this is the cleanest high-protein bar we've scored.
- #2. BC Snacks 2x Protein Chocolate Brownie Crunch Bar - Protein Score 10.0/10 · Clean Score 8.6/10 · 21.9g/serve
With a Protein Score of 10.0/10, this Choc Raspberry bar is a near-perfect entry. It delivers a solid 21g of protein per serve with just 0.4g of sugar per 100g, which is about as low as it gets in this category. The profile is lean, packing just a single additive for a Clean Score of 9.9. On the numbers, this Fibre Boost bar is functionally identical to our number one pick, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip. They share the same top Protein Score, Clean Score, and lowest-in-category sugar figure. This isn't a silver medal, it's a dead heat. Your choice simply comes down to whether you prefer raspberry or choc chip.
- #3. BC Snacks High Protein Bar 4 Pack Chocolate Brownie Crunch - Protein Score 10.0/10 · Clean Score 8.6/10 · 10.9g/serve
With a Protein Score of 10.0/10, this Choc Mint bar is another standout from the Fibre Boost range. The numbers are elite across the board, packing 21.3g of protein per serve with just 0.4g of sugar per 100g. That sugar figure puts it on equal footing with our number one pick, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip. Its Clean Score of 9.9/10, driven by only one additive, confirms it's one of the cleanest protein bars we've scored. While it doesn't lead the category for protein density, its 35.5g of protein per 100g is still very strong. The entire raw, cold-pressed lineup from this brand performs exceptionally well, locking out the top spots by pairing solid protein with almost no sugar and minimal processing. If you're after a clean, high-protein bar and prefer a mint flavour, this one is hard to beat.

Editorial deep dive
Hunting for a low-sugar protein bar often feels like a trap. You dodge the sugar, only to get hit with a long list of sugar alcohols like maltitol or a stack of artificial sweeteners. While these keep the sugar number down on the label, they can be a real problem for gut comfort. The protein bar shelf at Coles and Woolworths is a minefield of these trade-offs, but a few get the balance right. The top of our list is dominated by one brand that cracks the code. The Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip leads the pack with just 0.4g of sugar per 100g. Its siblings, like the Choc Raspberry and Choc Mint flavours, are right there with it. What's is how they do it, using stevia as the sweetener and keeping the additive count to just one. This isn't a case of swapping one problem for another; it's a genuinely clean, low-sugar bar. This clean approach stands out when you look at other popular low-sugar options. Brands like BSc and Quest also post very low sugar figures, which is great to see. The BSc High Protein Bar Cookies & Cream, for instance, has only 1.2g of sugar per 100g. However, the sweetness often comes from sugar alcohols like maltitol or a blend of sweeteners including erythritol and sucralose. For many people, that's perfectly fine, but if you're sensitive, it's a detail worth checking on the ingredient list. Of course, protein is still the main event. While Fibre Boost delivers a solid 34.8g of protein per 100g in its leading bar, it's not the densest on the shelf. That title goes to the BSc High Protein Bar Salted Caramel, which packs a massive 52.7g of protein per 100g. It's a reminder that shoppers need to decide what their priority is: the absolute lowest sugar, the highest protein hit, or the cleanest ingredient panel. Ultimately, if you're looking for a protein bar that is both low in sugar and built on a clean, simple formula, the choice is clear. The Fibre Boost range consistently proves you don't need to compromise with a long list of additives or sugar alcohols to create a quality low-sugar protein bar. They are the standout picks for anyone wanting to minimise sugar without the usual catches.
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.

We also consider secondary factors like protein content and the Clean Score, which is our rating for ingredient list simplicity and the absence of artificial additives.
