Optimum Nutrition High Protein Vanilla Shake
Optimum Nutrition High Protein Vanilla Shake: independently scored 10.0/10 on Protein Score and 8.4/10 on Clean Score by ProteinScore.
30g protein per serve · 203 cal · 8.7g sugar · 437mg sodium · 375mL serve.
Overview
This vanilla shake from Optimum Nutrition is a direct play for the convenience-led protein shopper, packing more than double the protein of standard flavoured milk into a single-serve bottle. With 8g of protein per 100mL, it clears the category average we track for ready-to-drink products, making it a genuinely useful option when you can't be bothered with powders and shakers. Compared with its sibling, the High Protein Banana Shake, this vanilla version offers the exact same protein and sugar profile. The sweetness comes from sucralose (955), not added sugar, which keeps the total sugar per bottle down to just 8.7 grams - a fraction of what you'd find in a typical milkshake from the fridge aisle. The trade-off is a list of seven additives, mostly stabilisers like carrageenan and gellan gum, which are there to ensure a consistent, smooth texture without the product separating on the shelf. We see this as a pure convenience play. It's for the person who needs a reliable protein top-up on the way home from the gym or as a filling snack to keep at the office. It doesn't pretend to be a whole-food smoothie, and it delivers on its core promise of high protein without a huge sugar load.
Protein Score: 10.0/10
This is the kind of grab-and-go bottle you reach for when convenience trumps all else. The 30 grams of protein it delivers in a single 375mL serving is substantial, putting it well ahead of the typical ready-to-drink product in the chiller and earning it a 9.4/10. It squarely hits the mark for a post-workout recovery drink or a genuinely filling snack. The protein source is a blend of milk solids and caseinate, which are standard, effective dairy proteins. This shake provides 14.8 grams of protein for every 100 calories consumed, making it a dense source that prioritises the key macro over everything else. It's a strong performer in a crowded field. Stack this against a regular flavoured milk, and the difference is stark: you're getting more than double the protein for a fraction of the sugar. For anyone looking to replace the shaker-and-powder routine with a simple, pre-made option, this is a compelling choice that delivers the numbers.
Clean Score: 8.4/10
No added colours or preservatives feature on the ingredient list for this vanilla shake. The focus is on delivering a stable, smooth drink, which results in a Clean Score/10. This places it right on the category average for ready-to-drink protein products we've analysed, making it a standard choice from a processing perspective. The ingredient list totals 13 items, with seven of those being additives. The sweetness is achieved with sucralose (955), an artificial sweetener, which avoids the sugar load of traditional flavoured milks. The rest of the additives are primarily stabilisers and thickeners, like carrageenan and gellan gum, used to create a consistent mouthfeel and prevent the milk proteins from separating over time. Ultimately, the additives are the price of convenience, ensuring the product holds up on the shelf and in your gym bag. For shoppers who prioritise a short, clean ingredient list above all, this won't be the top pick. But for those who accept some processing for a high-protein, low-sugar outcome, it's a perfectly reasonable trade-off.

Frequently asked questions
- How much sugar is in a whole bottle?
- A single 375mL bottle contains 8.7 grams of sugar. Importantly, this is not added sugar; it's naturally occurring lactose from the milk ingredients. This is significantly less than a standard flavoured milk, which often contains 10-12g of sugar per 100mL. This shake keeps the sugar low by using the artificial sweetener sucralose (955) instead. We'd consider it a low-sugar choice in this category.
- Is this a good shake for after the gym?
- Yes, with 30 grams of protein, it's a strong option for post-workout recovery. The protein comes from a blend of milk solids and casein, which are effective for muscle repair. Its main advantage is convenience, offering a ready-made alternative to carrying protein powder and a shaker. If you need a quick and easy protein source on the go, this bottle fits the bill perfectly.
- How does it compare to other Optimum Nutrition shakes?
- This vanilla shake has a very similar nutritional profile to other flavours in the same line. For instance, it matches the brand's High Protein Banana Shake, offering the same 8g of protein and 2.3g of sugar per 100mL. The main difference is simply the flavour. Optimum Nutrition also has a higher-protein 'Pure Pro 35' range for those seeking an even bigger protein hit. In our view, this shake is a solid mid-range option within the brand's lineup.
- Where can I buy this protein shake in Australia?
- This Optimum Nutrition shake is catalogued in the chilled drinks aisle at Coles supermarkets. While it's listed there, availability can vary by store location. The brand is owned by the US company Glanbia and its products are widely distributed, so you may also find it available for purchase directly from the brand's Australian website or other supplement retailers. We'd suggest checking the supermarket fridge first.
- What are the stabilisers in this drink for?
- The ingredient list includes five stabilisers: sodium phosphate dibasic, cellulose microcrystalline, sodium carboxymethylcellulose, carrageenan, and gellan gum. In a high-protein milk drink like this, these ingredients are essential to create a smooth, consistent texture and prevent the milk proteins from settling at the bottom. Without them, the shake would likely separate and feel gritty. They are the trade-off for a convenient, shelf-stable product that doesn't need blending.
