Overview
The two-litre carton of protein milk is an unusual format, shifting the product from a single-serve convenience buy to a multi-serve fridge staple. It's a practical solution for a household with a few protein drinkers, or for someone who wants a regular post-gym top-up without the faff of powders. The trade-off for this convenience is the sheer volume of sugar in the carton: a full 106 grams, albeit from naturally occurring milk lactose rather than added sugar. This Chocolate version sits alongside the brand's 'Plus Protein Chocolate No Added Sugar Flavoured Milk', matching it on both protein and sugar content. It's part of a broader push by Oak to bring its signature flavoured milk taste into a space dominated by more functional, less nostalgic products. Compared to the typical protein drink we track, this bottle is a little lower on protein density and carries a bit more sugar per 100mL. Its ingredient list length is right on the category average, reflecting the processing needed to deliver a smooth, stable, high-protein milk drink. Ultimately, this is classic chocolate milk taste with a serious protein boost. We see it as a bulking tool or a more indulgent recovery drink, where the calories and sugar are less of a concern than getting a fast, easy 30 grams of protein that actually tastes good.
Protein Score: 9.4/10
Oak's push into the protein space brings its classic flavoured milk credentials to a higher-protein format. With 30g of protein in a 500mL serve, it's a significant step up from standard milk drinks, earning an 8.7/10. The protein-per-calorie density is solid, landing comfortably above the category average for ready-to-drink products. That 30g serve easily replaces a standard powder-and-shaker effort, doubling the protein of many smaller RTDs. It's a genuine post-gym option drawn straight from the fridge, no mixing required, and a big step up from the 3-4g of protein you'd find in 100mL of regular flavoured milk. The catch is the 26.5g of sugar that comes with it. While it's naturally occurring lactose and not added sugar, it's still a hefty amount for a single drink. This makes it more of a bulking tool than a lean recovery choice for an athlete watching their macros closely.
Clean Score: 7.3/10
Is this just a standard flavoured milk with extra protein? The ingredient list suggests a bit more processing is involved to hit the numbers. With 13 ingredients including five additives, it scores a 7.9/10, landing just below the typical drink in this aisle for ingredient simplicity. The use of artificial sweeteners Acesulphame K (950) and Sucralose (955) is what keeps the total sugar count to just the naturally occurring lactose. A stabiliser (Carrageenan, 407) helps create the familiar smooth texture, while colours (155, 133) deliver the classic chocolate milk look. The inclusion of a lactase enzyme is a thoughtful touch, making the high dairy content potentially easier on the stomach. For shoppers who prioritise a short, whole-food ingredient list this won't be the pick, but the additives are doing a specific job here: delivering a familiar taste without an added sugar penalty.

Frequently asked questions
- Is Oak Plus Protein good for post-workout recovery?
- Yes, it can be a solid choice for post-workout recovery. A 500mL serve provides 30 grams of dairy protein, which is well within the range needed to support muscle repair and growth after exercise. The milk-based protein offers a complete amino acid profile. However, it also contains 26.5 grams of sugar, which should be factored into your daily nutrition goals. We think it's a great-tasting, convenient option if you're not strictly watching your sugar intake.
- Should I drink the whole 500mL serve in one go?
- A full 500mL serve delivers the advertised 30g of protein, but it also comes with 310 calories and 26.5g of sugar. While this is fine as a post-workout recovery drink for many, it is a significant single-serve load. If your protein needs are lower or you're watching your calorie and sugar intake, you could easily split the serve. A 250mL drink would still provide a useful 15g of protein. We'd say drink the full serve post-gym, but consider a half-serve for a simple snack.
- Is Oak Plus Protein lactose-free?
- No, it is not strictly lactose-free as its base is skim milk and milk solids. However, the ingredient list includes lactase, an enzyme that breaks down lactose, the natural sugar in milk. This means it is designed to be low-lactose and may be easier to digest for people with lactose sensitivity than regular milk drinks. If you have a diagnosed lactose intolerance, you should consult a health professional. For those who just find regular milk heavy, this could be a good option.
- Where can I buy the 2L Oak Plus Protein milk?
- This 2-litre carton of Oak Plus Protein is typically stocked in the chilled dairy aisle of major supermarkets. We have it catalogued as being available at Coles. It may also be available at other retailers or direct from the brand's owner, Lactalis. As it is a refrigerated product, you will find it alongside other fresh milk and flavoured milk drinks, not on the long-life UHT aisle. We'd check the main supermarket chains first.
- How does this compare to regular Oak chocolate milk?
- Oak Plus Protein is a significant step up in protein from the brand's regular flavoured milk. This version packs 6 grams of protein per 100mL, whereas standard flavoured milk usually sits around 3-4g. It also uses artificial sweeteners to avoid added sugar, keeping the sugar content to 5.3g/100mL from milk alone, which is about half that of many classic chocolate milks. In short, you get much more protein and less total sugar.
