The best RTD protein shakes in Australia, scored on protein density, sugar and ingredients. The top picks genuinely earn the 'high protein' label.
43 products ranked. Updated 2026-06-13.
Overview
The protein drink aisle is a minefield, split between essentially flavoured milk and genuinely useful post-gym options. The top of our rankings is claimed by Musashi Shred & Burn Chocolate Protein Shake, which earns a Protein Score of 10.0 thanks to a huge 31.7g of protein per serve and a lean 0.2g of sugar per 100ml. On paper, it's a near-perfect macro profile for a ready-to-drink format. Optimum Nutrition's Pure Pro range matches Musashi on performance, with the Pure Pro 50 Vanilla also hitting 9.9g of protein per 100ml. These drinks, found on the shelves at Coles and Woolworths, prove you don't have to compromise on protein density to find a solid grab-and-go option. Here's our verdict: despite its top score, the Musashi drink is loaded with 12 additives, so we say skip it. The cleaner, smarter picks are right there in the top three. Optimum Nutrition Pure Pro 50 Vanilla gets the job done with 6 additives, while the Pure Pro 35 Protein Shake Chocolate 355ml has just 5. For a high-protein drink without the long list of extras, grab an Optimum Nutrition instead.
The verdict
While the Musashi Shred & Burn Chocolate Protein Shake scores highest, its list of 12 additives per serve is a red flag, so we say skip it. The Optimum Nutrition Pure Pro 50 Vanilla also gets a pass from us with 6 additives. For a smarter pick that still leads on protein, grab the Optimum Nutrition Pure Pro 35 Protein Shake Chocolate 355ml. It delivers 9.9g of protein per 100ml and 35g of protein per serve with a much more reasonable ingredient list. The wider Optimum Nutrition Pure Pro range is the clear go-to for anyone chasing maximum protein density without a huge sugar hit. If you prioritise a cleaner label over raw protein numbers, the Rokeby Protein Smoothie Vanilla Wafer is the standout. It avoids artificial sweeteners entirely, which is rare in this category. It's a trade-off between the highest protein figures and the simplest ingredients, and Rokeby wins that second race comfortably.
Rankings
- #1. Muscle Nation RTD Protein Shake Vanilla Ice Cream - Protein Score 10.0/10 · Clean Score 8.5/10 · 30g/serve
With a Protein Score of 10.0/10, this drink is all about the numbers. It packs a huge 31.7g of protein per serve and 8.5g per 100ml, putting it at the top of the ready-to-drink pile. Sugar is almost non-existent at just 0.2g per 100ml, and calories are kept low at 48 per 100ml. On pure protein delivery, it's hard to beat. But here's the catch. The Musashi drink gets there with 12 additives, a heavy load of thickeners, gums and emulsifiers. If a clean label matters to you, skip it. This one is purely for the macro-focused shopper who needs maximum protein on the go and isn't fussed about the ingredient panel. For a simpler drink, look further down our list.
- #2. Optimum Nutrition High Protein Banana Shake - Protein Score 10.0/10 · Clean Score 8.2/10 · 30g/serve
A perfect Protein Score of 10.0/10 puts this Optimum Nutrition drink right at the top of the category. The numbers are huge: a massive 50g of protein per serve, making it one of the most protein-dense options we've scored at 9.9g per 100ml. It shares the top Protein Score with our guide winner, Musashi Shred & Burn Chocolate Protein Shake, delivering pure protein performance with barely any sugar. The catch is the additive load. With 6 additives on the label, it's a trade-off for all that protein. If you're after a cleaner label, skip it and look to the Rokeby Protein Smoothie Vanilla Wafer instead. For shoppers chasing the absolute highest protein figure in a single bottle, this delivers, but the compromise on ingredients is worth noting.
- #3. Optimum Nutrition High Protein Strawberry Shake - Protein Score 10.0/10 · Clean Score 7.9/10 · 30g/serve
Optimum Nutrition's Pure Pro 35 earns a perfect Protein Score of 10.0/10, putting it on equal footing with our number one pick, Musashi Shred & Burn Chocolate Protein Shake. It's one of the most protein-dense drinks we've scored, delivering 9.9g per 100ml, which adds up to a hefty 35g protein per serve. The formula is lean elsewhere too, with just 0.3g of sugar and 47 calories per 100ml, and Clean Score of 8.5.5/10 from five additives. This is a straightforward, high-performance protein drink. It doesn't have the fat-burner angle of the Musashi drink, instead focusing purely on a big protein hit with minimal sugar and calories. If a simple and effective refuel is what you're after, this is one of the best options available. It nails the macros without any extra complexity.

Editorial deep dive
Ready-to-drink protein drinks are all about convenience. They save you the faff of powders and shakers, offering a quick protein hit straight from the chiller cabinet at Coles or Woolworths. While many are just fancied-up flavoured milks, the top of our rankings shows what's possible when brands get serious about the nutritionals. On the numbers alone, Musashi Shred & Burn Chocolate Protein Shake leads the category, earning a perfect Protein Score of 10.0. It delivers a solid 8.5g of protein per 100ml and keeps sugar low at just 0.2g per 100ml. It's a formula that clearly prioritises protein delivery over everything else, which is exactly what you want from a product like this. But here's the trade-off. That top-scoring formula is propped up by 12 additives. For us, that's too many stabilisers, emulsifiers, and thickeners in one bottle. The runner-up, Optimum Nutrition Pure Pro 50 Vanilla, isn't much better with its 6 additives. When the ingredient list gets that long, we say skip it. A much cleaner pick sits just a couple of spots down the list. The Optimum Nutrition Pure Pro 35 Protein Shake Chocolate 355ml matches the best on protein density with 9.9g per 100ml but does it with a more reasonable 5 additives. It's still not a whole-food snack, but it's a far better compromise for a convenient protein top-up. So while Musashi takes the crown on paper, the smarter choice is the Optimum Nutrition Pure Pro 35. It proves you don't have to accept a dozen additives to get a high-protein, low-sugar drink on the go. Always check the back of the label, not just the front.
Brand-by-brand notes
Musashi
Musashi has long targeted the Australian sports nutrition crowd, and their ready-to-drink lineup is easy to track down. You will find both of the 2 protein drinks we've scored sitting in the chilled aisles of major supermarkets like Coles, Woolworths and Aldi. They focus heavily on the performance market, offering straightforward shakes when you need to refuel without mixing powders. The numbers across this tight range are formidable.It delivers 8.5g of protein per 100ml while keeping sugar right down to 0.2g per 100ml. On the flip side, the Musashi High Protein Shake Vanilla serves as the weakest in their lineup, dropping slightly to 8.2g of protein per 100ml while spiking to 5.7g of sugar per 100ml. If you are grabbing one off the supermarket shelf, the chocolate option is the obvious play. Reach for the leader to maximise your protein intake without the sugar penalty. Skip the vanilla version if you want to minimise carbohydrates, or look to the Atkins Creamy Vanilla Protein Shake if you want a vanilla profile that pushes sugar down to a category-low 0.02g per 100ml.
Muscle Nation
Muscle Nation made its name in the Australian sports nutrition line before expanding its reach into everyday retail. Today, all 3 protein drinks we cover here are stocked in major Australian supermarkets, making them an easy grab during your weekly Coles or Woolworths trip. The brand bridges the gap between gym-focused supplements and convenient chilled options. Across the range, this brand shows strict consistency, averaging 7.5g of protein and just 1.6g of sugar per 100ml. While the category crown belongs to the Musashi Shred & Burn Chocolate Protein Shake, Muscle Nation holds its own with highly controlled macros. The standout Muscle Nation RTD Protein Shake Strawberry Milkshake hits exactly 7.5g of protein per 100ml and 1.6g of sugar per 100ml, reflecting a tightly managed formula that barely wavers across the lineup. If you need a reliable macro profile without waiting for an online delivery, these drinks get the job done. Grab the Muscle Nation RTD Protein Shake Strawberry Milkshake if you want a familiar taste that keeps carbohydrates in check. However, with multiple stabilisers and artificial sweeteners driving that low-sugar profile, we say skip it if you are watching your additive intake and pick up the Rokeby Protein Smoothie Vanilla Wafer instead. Otherwise, it remains a highly consistent option for a quick refuel straight from the supermarket fridge.
Optimum Nutrition
Optimum Nutrition is a major American sports performance brand that has successfully crossed over from the supplement shop into the mainstream fridge. This category is genuinely mixed-channel, and of the 8 protein drinks we score for them, 4 are stocked at Coles and Woolworths while the other 4 are found at independent retailers. They bring the serious macro profiles from their powder tubs straight into their ready-to-drink formats. The lineup averages a very strong 8.9g of protein and just 1.3g of sugar per 100ml across the board. Optimum Nutrition Pure Pro 50 Vanilla is the standout, claiming the category title for the highest protein at 9.9g per 100ml alongside a tiny 0.3g of sugar. It shares that density with its Pure Pro sibling flavours, delivering a massive 50g of protein per bottle for serious recovery. While the overall category leader is the Musashi Shred & Burn Chocolate Protein Shake, the Pure Pro range holds its own if you want maximum protein volume. We rate this range highly for anyone who needs a large macro hit on the run, but keep in mind that every bottle relies on artificial sweeteners to keep the sugar low. If you are doing a supermarket run, their standard High Protein shakes offer 8g of protein per 100ml, but the Pure Pro bottles are worth hunting down at specialty stores if you want the absolute highest yield. Grab the 50g bottles when you genuinely need maximum dietary protein without the extra carbohydrates.
Dairy Farmers
Dairy Farmers is one of the oldest names in the Australian dairy chiller, now operating under the Bega umbrella. Their sports nutrition line includes the 5 protein drinks we score in our index. You will find all 5 of these protein drinks stocked in major Australian supermarkets, making them an easy grab at Coles, Woolworths, or Aldi. The brand delivers a highly uniform run of macros, averaging 7.5g of protein and 4.6g of sugar per 100ml. That sits a fair way behind the category leader, Musashi Shred & Burn Chocolate Protein Shake, which delivers 8.5g of protein and just 0.2g of sugar per 100ml. The standout is the Dairy Farmers Protein Smoothie Vanilla, hitting 7.5g of protein per 100ml alongside 4.6g of sugar per 100ml. The weakest link is the Dairy Farmers Protein Smoothie Drink Banana Honey, carrying the exact same 7.5g of protein and 4.6g of sugar per 100ml but relying on a noticeable sweetener load. We do not give nutritional advice, but the data shows these function more like fortified milks than ultra-lean sports formulations. If you need convenience on a supermarket trip, the vanilla option works quite well. Because sweeteners 950 and 951 appear across the board, skip the banana honey flavour if you want to minimise additives. They are an accessible chiller fix, just not the leanest drinks on the market.
Pauls
Pauls relies on its massive dairy footprint to push its PLUS+ range into the functional space. You will find all 4 protein drinks we score from them sitting right in the chilled dairy cabinet on your regular supermarket trip to Coles, Woolworths, or Aldi. They lean heavily on standard milk proteins and polydextrose for bulk, aiming at everyday shoppers looking for a quick top-up rather than offering highly refined sports nutrition. Across the lineup, the macros are identical. Every carton sits at 7.5g of protein per 100ml and 5.1g of sugar per 100ml, meaning they trail the sharper options in our index. To put that in perspective, the category leader, Musashi Shred & Burn Chocolate Protein Shake, delivers 8.5g of protein per 100ml with just 0.2g of sugar per 100ml. We highlight the Pauls PLUS+ Protein Double Espresso Caramel Flavoured Milk as both the standout and the weakest, purely because the entire range relies on the exact same base of skim milk, lactase enzyme, and artificial sweeteners. If you just want a straightforward milk drink with a protein bump, these are easy to throw in the trolley. However, the heavy use of sucralose and acesulfame potassium means they take a hit in our scoring. If you prefer your dairy without the artificial sweeteners, skip these and look for the Rokeby Protein Smoothie Vanilla Wafer instead, which leads the category on ingredient purity.
Crankt
Crankt sits squarely in the grab-and-go cooler of major Australian supermarkets, pushing a functional lineup of protein drinks for shoppers hitting Coles or Woolworths. They aim for the middle ground between standard supermarket drinks and dedicated sports nutrition. While other brands chase massive protein numbers, Crankt keeps things steady with a moderate nutritional profile that works for a quick top-up rather than a heavy recovery hit. Across the 3 protein drinks we score in our index, the brand averages 5.2g of protein and 2.7g of sugar per 100ml. The standout in their range is the Crankt Premium Protein Shake Chocolate, which delivers 5.2g of protein and 2.6g of sugar per 100ml. While the sugar load is reasonable, the protein density falls noticeably short of the category's top end. For context, heavy hitters like Optimum Nutrition Pure Pro 50 Vanilla push 8.5g of protein per 100ml, and the overall leader, Musashi Shred & Burn Chocolate Protein Shake, earns a Protein Score of 10 by offering much leaner macros. If you are ticking off a supermarket trip, Crankt is accessible but ultimately middle-of-the-pack on the numbers. Shoppers aiming for serious protein density should skip the wider Crankt lineup and look at the category leaders instead. We suggest grabbing the Crankt Premium Protein Shake Chocolate if you just need a mild top-up on the run, but if you want to maximise your intake, there are harder-working drinks sitting right next to it in the fridge.
Dare
Dare is a massive name in the Australian iced coffee scene, backed by Bega Group. While they are famous for their traditional caffeine hits, they have stepped into the functional space with a small line of protein-fortified milks. We have scored 3 protein drinks from their lineup, all of which are readily stocked in the fridge aisles at major Australian supermarkets like Coles and Woolworths. On the numbers, this range sits noticeably lower than the heavy hitters in our index. The Dare lineup averages 6.0g of protein and 4.6g of sugar per 100ml, making these more of a caffeinated milk drink with a protein bump rather than a dedicated recovery tool. Their standout, Dare Protein Mocha Flavoured Milk, delivers 6g of protein and 4.5g of sugar per 100ml alongside artificial sweeteners.If you are already grabbing a morning coffee from the Coles or Woolworths dairy case and want a slight macronutrient upgrade, the Dare protein drinks do the job. However, shoppers looking for maximum protein yield should probably skip these and look toward the dedicated sports nutrition brands nearby. They are a convenient supermarket pickup for caffeine lovers, but they fall short if your primary goal is hitting a strict daily protein target.
Atkins
Atkins is a veteran of the low-carb movement, known for stripping sugar out of everyday snacks and drinks. Across the two protein drinks we score in our index, the approach is strictly focused on keeping carbohydrates to an absolute minimum. You can easily pick these up during a regular supermarket trip, as both options are stocked in major Australian supermarkets like Coles and Woolworths. The brand averages a modest 4.6g of protein per 100ml. To put that in perspective, our top pick, Musashi Shred & Burn Chocolate Protein Shake, delivers 8.5g of protein per 100ml. Where Atkins makes its mark is on the sugar front. The standout Atkins Creamy Vanilla Protein Shake leads this list for the lowest sugar, registering just 0.02g of sugar per 100ml alongside its 4.6g of protein per 100ml. The weakest entry is the Atkins Smooth Chocolate Protein Shake, carrying the same 4.6g of protein per 100ml and 0.03g of sugar per 100ml. If your primary goal is finding a drink with virtually zero sugar, the vanilla option is worth grabbing off the shelf. If you are chasing serious muscle recovery, you might want to skip these and look for a denser formula. The artificial sweetener stack keeps the carbs down, but the overall protein payload is fairly light compared to the heavier options in the fridge.
Oak
Oak is a familiar face in the dairy cabinet, taking their classic flavoured milks and giving them a macro upgrade. The 3 protein drinks we track from the brand are all easily found during a standard supermarket trip to Coles or Woolworths. They lean heavily on milk solids and added lactase to keep things lactose-friendly while boosting the overall numbers. Across the lineup, Oak averages 6.0g of protein and 5.3g of sugar per 100ml, which trails behind the denser formulas in this guide. For context, the highest protein pick is Optimum Nutrition Pure Pro 50 Vanilla at 9.9g per 100ml. The Oak Plus Protein Salted Caramel Milk | 2L is the standout of the trio, delivering 6g of protein and 5.4g of sugar per 100ml in a bulk format. Meanwhile, the Oak Plus Protein Chocolate No Added Sugar Flavoured Milk ranks as their weakest entry, offering 6g of protein and 5.3g of sugar per 100ml while relying on artificial sweeteners to mimic the classic taste. If you want a nostalgic brand that hits moderate macros, Oak's bulk two-litre options do the job for the fridge at home. However, if you are grabbing a single serve from the supermarket cabinet to maximise your intake, you might want to look elsewhere. The outright leader in this category is the Musashi Shred & Burn Chocolate Protein Shake, which earns a Protein Score of 10 and offers a much sharper nutritional profile for those chasing serious numbers.
Füll+
Füll+ positions its drinks as complete on-the-go meals rather than just quick post-gym refuels. It is a relatively new face in the Australian functional beverage space, designed to bridge the gap between sports nutrition and everyday convenience. You will find both of the 2 protein drinks we have scored sitting in the dairy cabinets of major Australian supermarkets, making them an easy addition to your regular Coles or Woolworths trolley. On the numbers, this range sits firmly in the middle of the pack. Across the lineup, Füll+ averages 7.3g of protein and a fairly high 6.7g of sugar per 100ml. To put that in perspective, the category leader, Musashi Shred & Burn Chocolate Protein Shake, earns a Protein Score of 10 while keeping sugar down to just 0.2g per 100ml. The Füll+ Chocolate - On the Go Meal is their standout, delivering 7.3g of protein per 100ml alongside 6.6g of sugar per 100ml, while the Iced Coffee version matches the protein but nudges the sugar up slightly. If you are scanning the supermarket aisle for a liquid breakfast that actually fills you up, Füll+ does the job. However, if you are strictly tracking macros, the higher sugar content makes these drinks harder to justify as an everyday habit. We suggest skipping them if you want pure protein density and pointing your supermarket trip toward leaner options on the shelf instead.
Rokeby
Rokeby Farms is a familiar face in the chilled dairy cabinet, turning out a reliable lineup of milk-based protein drinks. We track 6 protein drinks from their range, and you will easily spot them during a routine supermarket trip at Coles, Woolworths, or Aldi. They lean heavily on filtered low-fat milk and lactase enzymes rather than heavily processed powders. Across the board, the brand averages 7.1g of protein per 100ml and 4.9g of sugar per 100ml. The Rokeby Protein Smoothie Choc Honeycomb is the standout here, delivering 7.1g of protein per 100ml alongside a lower 3.9g of sugar per 100ml. On the flip side, the Rokeby Protein Smoothie Strawberry is the weakest link, matching the protein but pushing to 5.9g of sugar per 100ml due to added cane sugar. If you want the cleanest ingredients, the Rokeby Protein Smoothie Vanilla Wafer earns a Clean Score of 9.8 in our index. While Rokeby delivers a strong fresh milk profile, they do not quite match the raw macros of the category leader. The top spot in our index belongs to the Musashi Shred & Burn Chocolate Protein Shake, which hits harder on overall protein density. Still, for a convenient grab from the chilled aisle, the Choc Honeycomb or Vanilla Wafer flavours are the ones to throw in your trolley, while the Strawberry is an easy skip.
Ice Break
Ice Break has been waking up early-morning tradies and road-trippers for decades. Now, the iconic Australian iced coffee brand is dipping its toes into the functional beverage space with a couple of high-protein variants. You will easily spot the two protein drinks we score in the dairy cabinets of Coles, Woolworths or Aldi right next to the standard iced coffees. On the numbers, these are caffeinated milk drinks first and protein top-ups second, averaging 4.7g of protein and a hefty 8.3g of sugar per 100ml. The standout is the Ice Break Iced Coffee Strong Espresso + Protein, offering 6g of protein and 6.6g of sugar per 100ml. Compare that to the category leader, Musashi Shred & Burn Chocolate Protein Shake, which pushes 8.5g of protein and just 0.2g of sugar per 100ml, and the macro gap is obvious. The weakest link is the Ice Break Iced Coffee Triple Shot, trailing with a minimal 3.3g of protein and 9.9g of sugar per 100ml. If you genuinely need a morning caffeine hit with a minor macro bump, grab the Strong Espresso version during your next supermarket run. It gives you a slight edge over standard iced coffees without going overboard on sweetness. However, if your primary goal is hitting a serious macronutrient target, skip the Ice Break lineup entirely. Shoppers aim for drinks that actually move the needle on recovery, so you are better off grabbing a dedicated protein shake from the same fridge aisle.
UP&GO
Sanitarium pitches UP&GO as the default liquid breakfast for busy mornings, rather than a hardcore sports supplement. We score the 2 protein drinks in their Protein Energize lineup, both of which are readily stocked across major Australian supermarkets like Coles, Woolworths and Aldi. The brand relies on a mix of soy and milk proteins to bump up the macros, aiming at everyday shoppers wanting a quick morning fuel-up before heading out. On the numbers, this small range leans heavily into carbohydrates compared to the wider category. Across these 2 protein drinks, UP&GO averages 7.2g of protein per 100ml alongside a fairly high 6.5g of sugar per 100ml. UP&GO Protein Energize Vanilla delivers 7.1g of protein per 100ml and 6.2g of sugar per 100ml, which works for a quick calorie hit but falls short of dedicated sports options. For context, the category leader, Musashi Shred & Burn Chocolate Protein Shake, earns a Protein Score of 10 by stripping sugar right back to 0.2g per 100ml while yielding 8.5g of protein per 100ml. If you just need a fast, familiar breakfast replacement while doing the weekly supermarket run, UP&GO Protein Energize does the job. However, if you are actively tracking macros and want to keep your sugar intake low, you might want to look at other shelves. Shoppers aiming for a leaner nutritional profile should walk past the breakfast aisle and grab a dedicated sports drink like the Musashi option instead. The added cane sugar and lower protein density make UP&GO harder to justify as a pure recovery drink.
Frequently asked questions
- What is the best protein drink in Australia 2026?
- The best protein drink we scored is the Musashi Shred & Burn Chocolate Protein Shake, which earns a perfect Protein Score of 10.0. It leads the pack in the Australian market for its excellent balance of high protein, at 8.5g per 100ml, and extremely low sugar content of just 0.2g per 100ml. While it claims the top spot, several drinks from Optimum Nutrition and Muscle Nation also achieved a Protein Score of 10.0, making them strong alternatives if you see them on the shelf.
- Is Musashi a good protein drink brand?
- We can't give nutritional advice, but on the numbers, Musashi makes the top-rated protein drink in Australia for 2026. Their Musashi Shred & Burn Chocolate Protein Shake achieves a Protein Score of 10.0, the highest possible score in our analysis. This is driven by a strong 8.5g of protein per 100ml combined with a minimal 0.2g of sugar per 100ml, placing it firmly at the top of the category for overall nutritional quality as we measure it.
- Optimum Nutrition vs Musashi protein drinks: which is better?
- While both brands are top, Musashi's top protein drink takes the crown for the best overall score. The Musashi Shred & Burn Chocolate Protein Shake earns a perfect Protein Score of 10.0. However, Optimum Nutrition's Pure Pro 50 range is the undisputed leader for protein density, packing 9.9g of protein per 100ml. This is the highest concentration of protein we found in any ready-to-drink product. Pick Musashi for the highest overall Protein Score, but go for Optimum Nutrition Pure Pro 50 if maximum protein per millilitre is your only goal.
- What is the best protein drink for weight loss?
- We don't give weight loss advice, but if you're looking for a protein drink with macros that support a calorie-controlled diet, the numbers are clear. The Atkins Creamy Vanilla Protein Shake has the lowest sugar we found, at just 0.02g of sugar per 100ml. Our overall winner, the Musashi Shred & Burn Chocolate Protein Shake, is also an pick, combining a high 8.5g of protein per 100ml with low 0.2g of sugar per 100ml, which can help with satiety while minimising sugar intake.
- How much protein is in an Optimum Nutrition Pure Pro 50 shake?
- The Optimum Nutrition Pure Pro 50 protein drinks, in both Vanilla and Chocolate flavours, contain 9.9g of protein per 100ml. This is the highest protein density of all 46 protein drinks we analysed, making it the leader on a pure protein-per-millilitre basis.

- The Atkins Creamy Vanilla Protein Shake is the leader for low sugar, containing just 0.02g of sugar per 100ml. The Atkins Smooth Chocolate Protein Shake is right there with it at 0.03g per 100ml. These are effectively trace amounts, making them the leanest options available if you are strictly minimising sugar intake. Several other products, including the top-scoring Musashi Shred & Burn Chocolate Protein Shake (0.2g per 100ml), are also low.
- Are Rokeby protein smoothies healthy?
- We can't say if a protein drink is healthy for you specifically, but Rokeby's products score exceptionally well for their clean ingredient lists. The Rokeby Protein Smoothie Vanilla Wafer earns the highest Clean Score of 9.8 in the entire category, as it avoids all artificial sweeteners, colours, and gums. It still provides a solid 7.1g of protein per 100ml, making it a standout choice for shoppers who prioritise a more natural ingredients panel.
- How does ProteinScore rate protein drinks?
- We rank protein drinks using two main scores calculated from the information on the label. Our Protein Score is a 0-10 rating that measures nutritional quality, rewarding high protein content while penalising excess calories and sugar. We also calculate a Clean Score, which assesses the ingredient list for things like artificial sweeteners, gums, and fillers. Together, these scores give a clear picture of what's inside each protein drink on Australian shelves.
