Cyclists wanting a ready-to-drink protein portion
A milkshake with protein stated per serving makes it easier to compare what you plan to drink after a ride. Some UHT products also permit cupboard storage before opening; check the particular pack.
Who is each option for?
Cyclists comparing sugars in flavoured drinks
Look at total sugars, ingredients and protein together rather than assuming chocolate milkshakes have similar nutrition or that a no-added-sugar claim means no sugar.
Riders making shakes at home
Plain milk lets you choose the other ingredients and serving size. Distinguish filtered milk from UHT long-life milk if storage before a ride or event matters.
What should you check before buying?
Decide whether you want a finished drink or a milk base, then compare the amount you will actually use and how you will store it.
| Priority | What to check | Your needs |
|---|---|---|
| Protein portion | Compare protein per 100ml and per intended serving. Check how many servings are in a carton: Sainsbury's lists 19g per 330ml serving and three servings in its Arla Protein Chocolate 1L carton. | I want to know how much protein is in the portion I will drink after cycling, rather than judging by the bottle size or flavour. |
| Sugars and ingredients | Compare total sugars per 100ml and per intended portion, then read the ingredients and any no-added-sugar claim. The NHS explains that the total-sugars figure includes sugars naturally present in milk. | A flavoured drink needs to fit alongside the rest of my food and drink; I may prefer to choose what goes into a homemade shake. |
| Storage and portion size | Check unopened storage instructions and what to do after opening. Tesco lists filtered milk and UHT long-life milk as separate formats; Sainsbury's says its Arla Protein Chocolate 1L carton needs refrigeration after opening. | If I am taking milk to an event or keeping it for later, I need a pack whose storage instructions fit that plan. A large carton also needs a realistic plan for its remaining portions. |
| Milk and lactose | Read the current allergen declaration and ingredients. A lactose claim is a separate consideration from milk allergy: Sainsbury's lists less than 0.01g lactose per 100g for Arla Protein Vanilla Fudge 200ml, which remains a milk product. | I need to check the actual pack for milk; if lactose matters to me, I also need to check the claim for that specific drink. |
Common buying mistakes
-
Assuming every milkshake has the same protein content
The products differ by both protein concentration and serving size. Tesco Groceries lists 3.3–3.4g protein per 100ml for its cited FRIJJ chocolate drinks, while Sainsbury's lists 19g per 330ml serving for Arla Protein Chocolate.
Compare protein per 100ml and in the amount you intend to drink. For a multi-serve carton, use its stated portion count.
-
Reading ‘no added sugar’ as ‘sugar-free’
Tesco Groceries lists 4.7g total sugars per 100ml for FRIJJ Reduced Sugar Chocolate despite its no-added-sugar claim. The NHS notes that naturally occurring milk sugars appear in the total-sugars figure.
Read the ingredients and the ‘of which sugars’ value, comparing equivalent volumes or the portions you intend to drink.
-
Opening a large carton without a storage plan
Sainsbury's states that its Arla Protein Chocolate 1L carton contains three servings and should be refrigerated and consumed within three days of opening.
Choose a portion you can use, and follow the current pack's instructions for the remainder.
-
Treating filtered milk as long-life milk
Tesco lists filtered milk separately from UHT long-life milk. The word ‘filtered’ does not establish that an unopened pack can be stored outside a fridge.
If you need cupboard storage before use, check for an explicit storage instruction on the exact pack.
Brand and retailer references
Arla Protein
The cited range includes a 1L chocolate carton with three stated servings and a 200ml vanilla-fudge drink.
- Sainsbury's lists 19g protein per 330ml serving for the chocolate carton and 20g per 200ml cup for the vanilla-fudge drink.
- Both are milk products. The cited chocolate carton needs refrigeration after opening, and its full litre is not the stated single serving.
FRIJJ
The cited Tesco Groceries listings are 471ml standard and reduced-sugar chocolate milkshakes.
- The reduced-sugar listing states no added sugar and 4.7g total sugars per 100ml, compared with 10.1g per 100ml for the cited standard chocolate drink.
- Both cited drinks contain milk and require refrigeration. Their listed protein is 3.3–3.4g per 100ml, so compare the intended portion rather than treating either as the same product as a protein-enriched shake.
Tesco
Tesco's milk listings include filtered and UHT long-life options that can serve as bases for homemade shakes.
- The separate formats let shoppers choose milk according to their ingredients and storage plans.
- A filtered designation alone does not establish cupboard storage. Check the exact pack's instructions.

Frequently asked questions
Is a standard chocolate milkshake the same as a protein-enriched shake?
No: the cited products state different protein amounts and serving sizes. Sainsbury's lists 19g per 330ml serving for Arla Protein Chocolate; Tesco Groceries lists 3.3g per 100ml for FRIJJ Chocolate and 3.4g per 100ml for FRIJJ Reduced Sugar Chocolate. Compare the amount you intend to drink, along with its other nutrition information.
Does ‘no added sugar’ mean a milkshake has no sugar?
No. Tesco Groceries lists 4.7g total sugars per 100ml for FRIJJ Reduced Sugar Chocolate, which carries a no-added-sugar claim. The NHS explains that naturally occurring milk sugars are included in the total-sugars figure on food labels.
Can filtered milk be stored like UHT long-life milk?
Do not assume it can. Tesco lists filtered milk and UHT long-life milk as separate formats; check the specific pack's unopened and post-opening storage instructions before planning to take it on a ride or keep it in a cupboard.
What happens after opening a large UHT milkshake carton?
Follow that carton's instructions. Sainsbury's says its Arla Protein Chocolate 1L carton can be kept in a cupboard unopened, but must be refrigerated after opening and consumed within three days. It contains three stated servings.
Are these dairy milkshakes suitable for someone with a milk allergy?
No, if the product contains milk. The cited FRIJJ drinks declare milk, and the cited Arla Protein drinks are milk products. Check the allergen declaration on the specific pack each time; a lactose claim does not mean a milk product is suitable for someone with a milk allergy.
