46 products scored. Updated 2026-07-25.
Overview
The protein drink aisle is a minefield of sugary flavoured milks masquerading as fitness fuel. Many popular options you'll spot at Coles and Woolworths offer barely more protein than regular milk but pack in the sugar. The best drinks, however, manage to deliver a serious protein dose without the sugar load, making them a genuinely convenient alternative to mixing a powder. On paper, the Musashi Shred & Burn Chocolate Protein Shake is our top-ranked pick. But with 12 additives listed on the label, it's a hard pass from us. We say skip it. For a much cleaner ingredient list, the Optimum Nutrition Pure Pro lineup is where you should be looking. It still delivers a massive protein hit with far fewer additives. Our pick is the Optimum Nutrition Pure Pro 50 Vanilla. It leads the category on protein density with 9.9g per 100ml, is virtually sugar-free at just 0.3g per 100ml, and lands a huge 50g of protein per serve. It strikes the best balance between a high Protein Score and Clean Score of 8.5, making it the grab-and-go drink we'd actually buy.
Editorial deep dive
The protein drinks in the chilled aisle offer a simple trade-off: convenience for compromise. They save you the faff of powders and shakers, but often come with a laundry list of additives and sweeteners. The real challenge isn't finding protein, it's finding a drink that delivers it cleanly without being a chemistry experiment. On pure numbers, Musashi Shred & Burn Chocolate Protein Shake leads the category with a Protein Score of 10.0. It packs a solid 8.5g protein per 100ml and keeps sugar low at just 0.2g per 100ml. But with 12 additives on the label, it's a hard pass from us. We say skip it. The runner-up, Optimum Nutrition Pure Pro 50 Vanilla, is in the same boat with six additives. For genuine protein density, the Optimum Nutrition Pure Pro range is the standout, delivering a category-leading 9.9g of protein per 100ml across several of its drinks. These are the ones to look for if your main goal is maximising protein in a single serve. You'll spot these potent options in the fridges at Coles and Woolworths, offering a serious protein hit without the sugar load. The sugar content across this category varies wildly. While the top performers like Optimum Nutrition and Musashi are virtually sugar-free, others can be surprisingly high. Some drinks creep towards traditional flavoured milk territory, so it pays to check the total sugar for the whole bottle, not just the per-100ml figure. For a clean profile, the Rokeby Protein Smoothie Vanilla Wafer earns our highest Clean Score of 9.8, using stevia and whole ingredients over a stack of artificial sweeteners. Our advice is to look past the top two ranks. The Musashi and the first Optimum Nutrition are just too loaded with additives to recommend. Instead, the real winner here is the Optimum Nutrition Pure Pro 35 Protein Shake Chocolate 355ml. It matches the top protein density at 9.9g per 100ml and keeps its additive count to a more reasonable five, making it the smartest pick of the high-performers.

Frequently asked questions
- What is the best protein drink in Australia 2026?
- The top-scoring protein drink in Australia for 2026 is the Musashi Shred & Burn Chocolate Protein Shake, which earns a perfect Protein Score of 10.0. It leads our analysis of 46 popular protein drinks by combining a strong 8.5g of protein per 100ml with low sugar at just 0.2g per 100ml. While it claims the top spot, several drinks from Optimum Nutrition's Pure Pro range also achieve a Protein Score of 10.0, sitting just behind on tie-breakers.
- Is Musashi a good brand for protein drinks?
- We don't give nutritional advice, but on the numbers, Musashi makes the top-rated protein drink in our Australian index for 2026. Their Shred & Burn Chocolate Protein Shake achieves a Protein Score of 10.0, the highest possible. This is driven by a great balance of high protein and minimal sugar. However, it's worth checking the label on their other products; the Musashi High Protein Shake Vanilla, for instance, has a much higher sugar content at 5.7g per 100ml.
- Musashi vs Optimum Nutrition: which protein drink is better?
- Both brands produce top protein drinks, but Musashi's Shred & Burn Chocolate Protein Shake takes the #1 spot with a Protein Score of 10.0, just ahead of Optimum Nutrition's best on tie-breakers. Where Optimum Nutrition's Pure Pro 50 range excels is protein density, leading the entire category with 9.9g of protein per 100ml. Musashi wins on its extremely low sugar content. For the highest overall score, pick Musashi. For the absolute maximum protein per millilitre, go with Optimum Nutrition Pure Pro 50.
- What is the best protein drink for weight loss?
- We don't give nutritional advice and no single protein drink causes weight loss, but the data shows some products have macros that may support those goals. On the numbers, the Atkins Creamy Vanilla Protein Shake is a standout, containing just 0.02g of sugar per 100ml, which is the lowest in our analysis. While its protein is more moderate at 4.Our #1 ranked Musashi Shred & Burn is another choice, with much higher protein and still only 0.2g of sugar per 100ml.
- How much protein is in an Optimum Nutrition Pure Pro 50 shake?
- The Optimum Nutrition Pure Pro 50 Vanilla protein drink contains 9.9g of protein per 100ml. This is the highest protein density among all 46 protein drinks we scored, a figure matched by the Chocolate and Coffee flavours in the same range. The '50' in the name refers to the total 50 grams of protein packed into the full 500ml bottle, making it one of the most substantial single-serve options available.
- Which protein drinks are lowest in sugar?
- The Atkins Creamy Vanilla Protein Shake is one of the lowest-sugar protein drinks available, with just 0.02g of sugar per 100ml. It shares this rock-bottom sugar content with its sibling, the Atkins Smooth Chocolate Protein Shake, and several Optimum Nutrition Pure Pro drinks. For comparison, our overall #1 pick, the Musashi Shred & Burn Chocolate Protein Shake, is also lean at 0.2g of sugar per 100ml. Always check the label, as some other protein drinks can contain more than 6g of sugar per 100ml.
- What is the cleanest protein drink in Australia?
- The Rokeby Protein Smoothie Vanilla Wafer earns the highest Clean Score of 9.8 in our analysis, making it our pick for the cleanest protein drink. Our Clean Score rates products from 0-10 based on their ingredient list, penalising additives like artificial sweeteners, gums, and colours. The Rokeby smoothie uses natural sweeteners like stevia and erythritol and has a shorter ingredient list than many competitors, helping it stand out in a category where long lists of stabilisers and emulsifiers are common.
- How does ProteinScore rate protein drinks?
- Our Protein Score is a 0-10 rating we calculate based on the nutrition information printed on the label of each protein drink. The score primarily rewards high protein content, both per 100ml and per total serve, as this is the main job of a protein drink. It then penalises for high amounts of sugar and total calories. The goal is to identify protein drinks that deliver a strong dose of protein without a significant trade-off in other areas.
