Optimum Nutrition High Protein Banana Shake
Optimum Nutrition High Protein Banana Shake: independently scored 10.0/10 on Protein Score and 8.2/10 on Clean Score by ProteinScore.
30g protein per serve · 206 cal · 8.7g sugar · 436mg sodium · 375mL serve.
Overview
For anyone who lives out of a gym bag, a ready-to-drink protein shake that doesn't need mixing is a very convenient shortcut. This bottle from Optimum Nutrition delivers a hefty 30-gram protein serve, which is more than double what many rivals in the chiller offer and lands far ahead of the typical protein powder on our index. Compared with its own High Protein Chocolate Shake, this banana flavour offers the exact same protein and sugar numbers. The 8.7 grams of sugar in the entire bottle comes entirely from naturally-occurring lactose in the milk protein base, with no added sugar. That figure is comfortably below the average for the ready-to-drink category we track, making it a smarter choice than most flavoured milks. To get that smooth texture and shelf stability, the formula relies on a blend of milk proteins and a suite of five different stabilisers, including carrageenan and gellan gum. Sweetness comes from sucralose (955), which keeps the total sugar and calorie count in check. It's a trade-off: you get the convenience and the big protein number, but the ingredient list is longer than a simple powder-and-water shake.
Protein Score: 10.0/10
The protein here comes from a blend of milk solids, sodium caseinate, and milk protein concentrate, a standard and effective base for a dairy drink. This combination delivers 30 grams of protein in the bottle, earning a 9.4/10 score that puts it well ahead of the category average. That 8g of protein per 100mL is more than double the amount found in regular flavoured milk, making it a genuinely high-protein option for post-workout recovery. The protein-per-calorie metric is also strong, meaning you get a substantial protein hit without a huge calorie cost. For a shopper needing a quick, no-fuss protein source on the go, this bottle is one of the more potent options in the supermarket chiller. It easily replaces the need for a shaker and bottle of powder when you're short on time.
Clean Score: 8.2/10
Optimum Nutrition's ready-to-drink shakes typically feature more ingredients than their powder counterparts, and this one is no exception. The 14 ingredients and eight additives land it a Clean Score/10, which trails the average for the category, where simpler formulas are common. The main drivers for the score are the five different stabilisers (sodium phosphate dibasic, cellulose microcrystalline, sodium carboxymethylcellulose, carrageenan, gellan gum) and an emulsifier. These are what give the shake its consistent, smooth texture and prevent the ingredients from separating on the shelf, but they also push the product further along the processing spectrum. Sweetness is handled by sucralose (955), an artificial sweetener used to avoid adding sugar. While effective for keeping the sugar content low, it won't suit shoppers who prefer to stick to whole-food ingredients or natural sweeteners like stevia.

Frequently asked questions
- Is Optimum Nutrition High Protein Banana Shake a stronger on the numbers choice?
- We can't say if it's a stronger on the numbers choice for you specifically, but the data shows it's a protein-dense protein drink with no added sugar. A single 375mL bottle provides 30g of protein for 206 calories, and its 8.7g of sugar comes naturally from milk (lactose). Compared to regular flavoured milk, it offers significantly more protein and less sugar, making it a strong contender for a post-workout recovery protein drink or a filling snack in Australia for 2026. However, it does contain eight additives, including artificial sweetener sucralose (955), which some shoppers prefer to avoid.
- How much protein is in an Optimum Nutrition High Protein Banana Shake?
- An Optimum Nutrition High Protein Banana Shake contains 30 grams of protein in a single 375mL bottle. This is a substantial amount, equivalent to a standard scoop of protein powder, making it a convenient option for post-exercise recovery without needing a shaker. Per 100mL, it has 8g of protein, which is more than double the 3-4g typically found in regular flavoured milk in Australia. The protein comes from a blend of milk solids, sodium caseinate, and milk protein concentrate, providing a high-quality dairy base for 2026.
- Is the Optimum Nutrition High Protein Shake good for muscle gain?
- We don't give specific nutritional advice, but its 30g of protein per bottle is a significant contribution towards daily protein needs, which are essential for muscle repair and growth. This amount is comparable to a typical post-workout shake made from protein powder. For anyone looking to support muscle gain, having a convenient, high-protein option like this on hand can be very useful, especially when you need a quick source of protein after a gym session. The protein is sourced from a high-quality dairy blend, which is effective for recovery.
- How does the Banana shake compare to other Optimum Nutrition shakes?
- This Banana shake has the same nutritional profile as several other flavours in the range, including the High Protein Chocolate Shake. Both provide 8g of protein and 2.3g of sugar per 100mL, with no added sugar. Optimum Nutrition also offers the Pure Pro 35 range, which is even higher in protein (around 9.9g per 100mL) and lower in sugar. The choice between them often comes down to flavour preference and how much protein you're aiming for in a single serve.

- Does the Optimum Nutrition High Protein Shake need to be kept in the fridge?
- Yes, this is a chilled product and should be kept in the fridge to maintain its freshness and quality. It's sold from the refrigerated aisle in supermarkets, not the long-life section.

Always check the packaging for specific storage instructions.
