Best Protein Bars at Woolworths - Ranked 2026
Walking the Woolworths protein aisle blind? We scored the full range so you don't have to read another label. The top picks aren't the loudest brands.
66 products ranked. Updated 2026-06-13.
Overview
Quest Protein Bar S'mores claims the top spot in our protein bar analysis, delivering 35g of protein per 100g with just 1.1g of sugar per 100g. The brand locks out the entire podium, with its Choc Chip Cookie Dough and Caramel Chocolate Chunk flavours sitting right behind. For a bar that packs a genuine 21g of protein per serve, it's a clear standout on the numbers. The trade-off for that low sugar figure is a reliance on sweeteners and added fibre. The S'mores bar contains six additives, which might be a dealbreaker for some shoppers. If you're chasing the absolute highest protein density, the BSc High Protein Bar range is unmatched. For a cleaner ingredient list, the bars from Grenade and BC Snacks are better picks. Ultimately, the protein bar shelf at Coles and Woolworths offers a few different paths. If your main goal is maximising protein while minimising sugar, and you're comfortable with the sweetener blend, the Quest Protein Bar S'mores is our top-ranked pick.
The verdict
Quest Protein Bar S'mores leads the list with a hefty 21g protein per serve and a tiny 1.1g sugar per 100g. On the numbers, it's a clear winner, but with six additives on the label, we'd skip it. The smarter pick is its sibling, Quest Protein Bar Choc Chip Cookie Dough, which delivers the same 21g protein per serve with a nearly identical 1.2g sugar per 100g and a slightly shorter ingredient list. For those wanting an even cleaner bar, the BC Snacks High Protein Bar Dark Chocolate Almond is a standout. It lands with just three additives, which is a rare find in this aisle. While the 11.4g protein per serve doesn't compete with the top Quest bars, it strikes a much better balance for anyone who prefers a simpler ingredients list for their desk drawer or post-gym refuel.
Rankings
- #1. BC Snacks High Protein Bar Raspberry Truffle Flavoured - Protein Score 10.0/10 · Clean Score 8.5/10 · 10.8g/serve
With a perfect Protein Score of 10.0/10, Quest's S'mores bar earns its top spot on pure numbers. You get a hefty 21g of protein per serve from a base of 35g of protein per 100g, with sugar kept right down to just 1.1g per 100g. But if you prioritise clean ingredients, skip it. The trade-off for these stats is a list of 6 additives, which is on the high side for our top-ranked protein bars. This is a bar for the protein-focused shopper who reads the macros first and the ingredients list second. The dense, chewy texture is a signature of the brand and it holds up well in a gym bag, making it a proper post-workout refuel. If you want maximum protein for minimal sugar and aren't fussed by a longer additive list, this is your pick from the supermarket shelf.
- #2. Quest Protein Bar Cookies & Cream | 60g - Protein Score 10.0/10 · Clean Score 7.8/10 · 21g/serve
With a Protein Score of 10.0/10, the Choc Chip Cookie Dough flavour matches the Quest Protein Bar S'mores for the top spot in our rankings. The numbers back it up completely, delivering 21g of protein per serve with low sugar count of just 1.2g per 100g. It's a classic flavour profile that doesn't compromise on the macros. The Clean Score of 8.3/10 is also strong, held back only slightly by its 5 additives, which is still a very number in this category. For shoppers who want a reliable, high-protein bar that keeps sugar to an absolute minimum, this Quest bar is a benchmark performer. If you see it on the shelf, it's one of the best you can grab.
- #3. BC Snacks Energy Bar Chocolate Brownie Espresso - Protein Score 10.0/10 · Clean Score 8.5/10 · 10.6g/serve
This bar earns a perfect Protein Score of 10.0/10, putting it in the top alongside our number one pick, Quest Protein Bar S'mores. You get a solid 20g of protein per serve in a bar that keeps sugar extremely low at just 1.4g per 100g. Calories are also well-managed at 299 per 100g, making it a lean choice. The Clean Score of 8.0/10 is solid, reflecting a formula with just 5 additives. This is the classic Quest proposition: high protein and minimal sugar without a massive list of thickeners and gums. For a reliable, macro-focused bar you can find easily on supermarket shelves, this is a strong contender.

Editorial deep dive
The protein bar shelf is a tale of two extremes. On one side, you have the ultra-processed, low-sugar bars engineered for maximum protein. On the other, you have bars that are closer to real food but often carry a much higher sugar load. Navigating this trade-off is the key to finding a bar that actually works for you, whether it's a gym bag staple or a desk-drawer snack. Quest nails the numbers game, which is why its bars occupy the top spots in our rankings. The Quest Protein Bar S'mores leads the category with a Protein Score of 10.0, driven by 35g of protein per 100g and just 1.1g of sugar per 100g. On paper, it's a clear winner. But the ingredient list tells another story, with six additives and a heavy reliance on sugar alcohols like erythritol and sucralose. For us, that's a red flag for gut comfort and overall quality. Frankly, despite its top score, we'd say skip it. The Quest Protein Bar S'mores and its sibling, the Cookies & Cream flavour, are just too loaded with additives for a comfortable recommendation. A far better starting point is the BC Snacks High Protein Bar Dark Chocolate Almond. It sits in our top five, delivers a solid 28.5g of protein per 100g, and does it all with only three additives, making it a much cleaner pick. Beyond the top ranks, the field is a mix of different philosophies. Brands like BSc push protein density to the absolute limit, with their High Protein Bar Salted Caramel packing a massive 52.7g of protein per 100g. Then you have brands like Carman's, whose bars often use more recognisable ingredients but can contain significantly more sugar. The Carman's High Protein Crisp Dark Choc Caramel, for instance, contains 18.6g of sugar per 100g, placing it in a different league entirely. For your first purchase from the shelves at Coles or Woolworths, look past the headline numbers. While Quest technically wins on our protein-centric score, the BC Snacks High Protein Bar Dark Chocolate Almond is the smarter buy. It balances a strong protein hit with a cleaner ingredient deck, which is the compromise we think most shoppers are actually looking for.
Brand-by-brand notes
Quest
Quest is a massive US import that helped shape the modern low-sugar snack aisle, and you will find them stocked across major Australian supermarkets. We track four of their protein bars in our index, built on a familiar formula of whey protein isolate, milk protein isolate, and a heavy dose of prebiotic fibre. If you are doing a standard supermarket run at Coles or Woolies, these blocky bars are genuinely impossible to miss. On the numbers, this tight lineup consistent. The four bars we score average 34.5g of protein per 100g and a tiny 1.4g of sugar per 100g. Quest Protein Bar S'mores claims the crown with a Protein Score of 10.It delivers 35g of protein per 100g and just 1.1g of sugar per 100g, making it our low-sugar pick on the shelf. The math barely dips across the range, though you do have to accept a heavy sweetener stack of erythritol and sucralose to get those exact macros. If you want raw macro efficiency from the supermarket aisle, this brand is hard to pass. Grab Quest Protein Bar S'mores for the optimal protein-to-sugar ratio, or pick up the tied Quest Protein Bar Choc Chip Cookie Dough which also hits that 1.1g of sugar per 100g mark. Just keep in mind that the heavy fibre and artificial sweetener load gives these bars a notoriously dense, chewy texture. They are functional, highly effective fuel to throw in the basket at Coles, rather than something you eat for the culinary thrill.
BC Snacks
BC Snacks is a familiar Australian name in the supermarket aisle, pitching straightforward protein bars without the aggressive supplement-brand marketing. All 11 protein bars we cover here are stocked in major Australian supermarkets, making them an easy grab during your weekly Coles or Woolworths grocery run. Across the lineup, these bars average 27.6g of protein and 4.0g of sugar per 100g, sitting reasonably well against the wider category benchmarks. The clear standout is the BC Snacks High Protein Bar Dark Chocolate Almond, delivering 28.5g of protein and just 2.2g of sugar per 100g. It actually ties for a clean pick in the category with a Clean Score of 8.9, alongside the Grenade Protein Bar Salted Caramel. While the overall category crown goes to the Quest Protein Bar S'mores, the BC Snacks dark chocolate option proves you can still find a decent nutritional profile without hunting down specialty brands. If you are walking the supermarket aisle and need a quick snack, the BC Snacks High Protein Bar Dark Chocolate Almond is the one to throw in the trolley. The rest of the range performs almost identically on the numbers, so your choice really comes down to flavour preference. It won't compete with the 50g-plus protein bars for a massive post-gym refuel, but it works perfectly as a low-sugar option you can pick up with your regular groceries.
BSc
The supermarket protein aisle is mostly BSc, Carman's and BC Snacks, with Body Science holding the largest footprint of the 16 protein bars in this guide. The long-running Australian sports nutrition brand builds products for everyday training rather than niche bodybuilding crowds. You will find all 16 protein bars we cover here stocked in major Australian supermarkets like Coles and Woolworths. Across the lineup, these bars average 35.3g of protein per 100g and keep sugar low at 3.4g per 100g. Our standout is the BSc Soft Protein Bar Banana Chocolate, delivering 29.4g of protein per 100g and 3.9g of sugar per 100g without an overly chalky texture. We rate the BSc High Protein Bar Salted Caramel as the weakest link, even though it stands as the highest protein option in the category at 52.7g per 100g and just 1.9g of sugar per 100g, because a heavy artificial sweetener stack ruins the profile. When you are throwing your weekly groceries into the trolley at Coles or Aldi, the soft-centre options are the ones to grab for a post-training snack. Skip the denser blocks if you want an enjoyable chew, as they lean too hard on additives to mask the heavy dairy blend. While the brand offers serious convenience on the supermarket shelf, shoppers wanting the absolute top should look for Quest Protein Bar S'mores, which leads the category with a Protein Score of 10.
Muscle Nation
Muscle Nation built its name in the sports nutrition space before pushing hard into the everyday snack aisle. You will spot all 10 of the protein bars we score for them sitting right on the shelves at Coles and Woolworths. They lean heavily on dessert-style branding, wrapping their bars in custard and cheesecake themes to catch the eye. The numbers across the range show a clear divide in macro performance. On average, the brand sits at 31.1g of protein and 6.8g of sugar per 100g. The Muscle Nation HIGH PROTEIN BAR - Choc Honeycomb leads their lineup with 43g of protein and just 2.3g of sugar per 100g. On the flip side, the Muscle Nation Cheesecake Protein Bar Zesty Lemon drags the chain, dropping to 24.2g of protein while pushing sugar up to 10.3g per 100g. If you are walking the supermarket aisle, stick to their High Protein line and skip the cheesecake variants. Shoppers look for high protein density without a massive sugar hit, making the Choc Honeycomb the one to throw in the basket. However, if you want the absolute peak of the category, the Quest Protein Bar S'mores still holds the number one spot overall.
Atkins
Atkins built its name on low-carb dieting long before the current fitness wave, but their modern footprint in the protein bar aisle is fairly small. We track just 2 protein bars from their range, both of which are easy to find on a standard Coles or Woolworths grocery run. They pitch heavily to the low-sugar crowd, though the ingredient lists lean heavily on artificial sweeteners to get there. Across the lineup, the brand averages 14.0g of protein and 3.0g of sugar per 100g. That protein average is noticeably light when you consider the category leader, Quest Protein Bar S'mores, earns a Protein Score of 10 and hits 35g of protein per 100g. The standout of the Atkins pair in our index is the Atkins Endulge Bar Chocolate & Coconut, delivering 13g of protein and 3.2g of sugar per 100g. On the flip side, the Atkins Endulge Bar Caramel Nut serves up a slightly higher 15g of protein and 2.8g of sugar per 100g, but carries added sugar alongside its sweetener stack. If you are tossing these in your supermarket trolley hoping for a massive post-gym recovery hit, the numbers fall short. They function more as low-sugar grocery treats than serious functional fuel. If you genuinely need density, skip the Atkins range entirely and grab the BSc High Protein Bar Salted Caramel, which leads the category with 52.7g of protein per 100g. If you just want a quick afternoon fix, the Chocolate & Coconut option is the better of the two Atkins bars.
Sam's Pantry
We track 3 protein bars from Sam's Pantry, a brand that aims straight for the casual snacking crowd. If you are doing the weekly shop, you will spot these easily since all 3 protein bars we cover here are stocked in major Australian supermarkets like Coles, Woolworths and Aldi. They position themselves as a convenient, everyday grab rather than a hardcore sports supplement. Across their lineup, the average protein sits at 21.2g per 100g, while the sugar average climbs to 22.0g per 100g. We score Sam's Pantry Protein Crisp Bars Dark Choc Caramel as both the standout and the weakest in their tight range, delivering 21.1g of protein per 100g alongside 21.2g of sugar per 100g. When you stack that against the category leader, Quest Protein Bar S'mores, which carries a Protein Score of 10 and leads the market with just 1.1g of sugar per 100g, the Sam's Pantry offerings look more like traditional treats with a minor protein bump. If you want a genuine high-protein hit without the heavy sugar load, we suggest you grab the Quest bar instead. Sam's Pantry is fine for a quick supermarket trip when you just want a sweet snack from the Coles or Woolies shelf, but the high carbohydrate numbers make it hard to recommend for strict macro tracking. Skip these if you want a lean profile, and look for cleaner options in the aisle.
Musashi
Operating long before protein bars hit the mainstream, Musashi is one of Australia's oldest sports nutrition brands. They have built a huge footprint across the country, moving from specialty supplement stores straight into the major retailers. You will find all 7 protein bars we cover here stocked in the everyday aisles at Coles and Woolworths. Across the lineup, the brand averages 31.3g of protein and 9.3g of sugar per 100g. The standout on the numbers is the Musashi Protein Crisp Choc Brownie, delivering 34g of protein and 6.3g of sugar per 100g. On the flip side, the Musashi Protein Wafer Bar White Chocolate trails the pack with 25g of protein and 11.7g of sugar per 100g. We like that Musashi keeps things highly accessible on a standard supermarket run, but the range is a mixed bag on the nutrition panel. Grab the Protein Crisp if you want a reliable macro profile to throw in your gym bag. If you are eyeing the wafer bars, we suggest skipping them and picking up the category leader, Quest Protein Bar S'mores, for a leaner run at the numbers.
Carman's
Carman's sits right in the middle of the mainstream supermarket aisle, heavily stocked across Coles, Woolworths, and Aldi. With 13 protein bars in our index, they hold the second-highest shelf footprint in this guide behind BSc. Across the lineup, the Carman's range averages 27.3g of protein per 100g and a fairly high 19.9g of sugar per 100g. If you want their best macro profile, grab the Carman's Plant Protein Bar Raspberry Pistachio, which delivers 24.5g of protein per 100g and 11.7g of sugar per 100g. These are essentially nut and seed bars with a protein bump, making them an easy grab during your weekly supermarket run. If you want serious macronutrients, you will need to look elsewhere in the aisle. The category leader, Quest Protein Bar S'mores, hits a Protein Score of 10 with just 1.1g of sugar per 100g, showing exactly where the Carman's range falls short on sugar control.
Frequently asked questions
- What is the best protein bar in Australia 2026?
- The best protein bar in Australia is the Quest Protein Bar S'mores, which earns a perfect Protein Score of 10.0 in our 2026 analysis. It leads our scoring of 69 popular protein bars because it combines high-quality protein (35g per 100g) with low sugar count of just 1.1g per 100g. This combination of strong macros makes it the top-ranked option for Australian shoppers looking for a genuinely effective protein bar without the extra sugar found in many alternatives.
- Are Quest protein bars good?
- We can't say if they're good for you specifically, but on the numbers, Quest makes some of the highest-scoring protein bars in Australia for 2026. Their S'mores flavour is our top-ranked bar with a Protein Score of 10.0, driven by 35g of protein per 100g and only 1.1g of sugar per 100g. Other flavours like Choc Chip Cookie Dough and Cookies & Cream also sit at the top of our rankings, consistently delivering high protein and very low sugar across the range.
- What is the best protein bar for weight loss?
- We don't give nutritional advice, but a protein bar that supports weight loss goals typically offers high protein for satiety with minimal sugar and calories. On the numbers, the Quest Protein Bar S'mores fits this profile well, delivering 35g of protein per 100g with only 1.1g of sugar per 100g. This strong macro profile helps manage hunger without contributing significant sugar to your daily intake, which is a key consideration for many people managing their weight.
- Quest vs BSc: which protein bar is better?
- Both Quest and BSc make top protein bars, but they win on different metrics. Quest's range, led by the Quest Protein Bar S'mores (Protein Score 10.0), is the best all-rounder, excelling on low sugar with just 1.1g per 100g. However, if your only goal is maximum protein density, BSc is the leader. The BSc High Protein Bar Salted Caramel packs an unmatched 52.7g of protein per 100g. For the best overall score and lowest sugar, our pick is Quest. For pure protein content, go with BSc.
- Which protein bar has the most protein?
- The BSc High Protein Bar range has the most protein per gram among all the bars we analysed. The Salted Caramel flavour leads the category with 52.7g of protein per 100g. Several other flavours in the same BSc range, like White Choc Raspberry and Cookies & Cream, are right there with it, also containing over 52g of protein per 100g. This makes them the densest options on the shelf if your primary goal is maximising protein intake.
- How does ProteinScore rank protein bars?
- We rank protein bars using our Protein Score, a 0-10 rating that measures a product's effectiveness based on what's on the label. The score is calculated from two main factors: protein density, which is the amount of protein per 100g, and protein quality, which considers the source of the protein. A bar with more protein from high-quality sources like whey or milk protein will score higher than one with less protein or lower-quality sources. We also calculate a separate Clean Score to assess additives and sweeteners.
- Are Carman's protein bars healthy?
- We don't give nutritional advice, but on the numbers, many Carman's protein bars contain a very high amount of sugar compared to the category leaders. For example, the Carman's High Protein Crisp Dark Choc Mint contains 21.5g of sugar per 100g, while top-scoring bars from brands like Quest have less than 2g per 100g. While they do provide a decent amount of protein, their high sugar content means they score much lower in our rankings than cleaner, leaner alternatives.
- What are the lowest sugar protein bars?
- The lowest sugar protein bar we scored is the Quest Protein Bar S'mores, containing just 1.1g of sugar per 100g. The brand achieves this by using alternative sweeteners like erythritol and sucralose instead of added sugar. Several other bars are right behind it, including the Quest Choc Chip Cookie Dough flavour (1.2g per 100g) and the BSc High Protein Bar Cookies & Cream (1.2g per 100g). These are the top choices if you're looking to minimise your sugar intake.
