Busy adults comparing bottled protein drinks
If you want a ready-to-drink addition to a snack or breakfast, compare protein for the amount you will drink. Bottle sizes and labelled serving sizes differ.
Who is this choice for?
Adults checking lactose and milk ingredients
A lactose-free declaration answers a different question from a milk-allergen declaration. Arla Foods UK labels its Protein Chocolate shake lactose-free but also lists milk as an allergen.
People choosing between a flavoured drink and a protein shake
An ordinary milkshake can contain protein without providing the same amount per bottle as a dedicated shake. Check the nutrition panel if protein, sugars or portion size will affect your choice.
What should you compare?
Start with the amount in the bottle you expect to drink, then compare nutrition per 100ml where pack sizes differ. Check ingredients and storage directions before deciding whether a drink fits your circumstances.
| Priority | What to check | Your needs |
|---|---|---|
| Protein amount | Check grams per bottle and the labelled serving size. For different bottle sizes, compare values stated on the same volume basis; do not treat per 100g as per 100ml. | I want to know what one bottle contributes. Arla Foods UK lists 26g protein in its 482ml Chocolate shake and UFIT lists 25g in its 330ml Chocolate shake. Tesco Groceries lists 3.2g per 100ml for Yazoo Chocolate and 3.8g per 100ml for FRijj Strawberry. |
| Sugars and energy | Read sugars per 100ml and for the amount you plan to drink. Check energy on the same serving basis. | Protein is not my only consideration. UFIT lists 10.9g sugars and 158kcal per 330ml Chocolate bottle; Tesco Groceries lists 8.6g sugars per 100ml for Yazoo Chocolate and 10.1g per 100ml for FRijj Strawberry. |
| Milk and lactose | Read the allergen declaration separately from any lactose-free wording. Check the declaration on the current pack. | If lactose is a concern, I need the product’s own lactose statement. Arla Foods UK labels its Chocolate shake lactose-free at less than 0.01g lactose per 100g, but declares milk as an allergen; lactose-free does not mean milk-free. |
| Other ingredients | Check the full ingredients list and allergen statement rather than relying on the flavour or protein claim on the front. | I need to check every ingredient relevant to me. ASDA Groceries lists milk and oats in its allergen information for UFIT Chocolate. |
| Use and storage | Check the bottle size, whether a pack contains more than one serving, and its directions after opening. | A bottle I can finish at once suits some days; on others, I need to know whether I can keep the remainder. Tesco Groceries lists two 200ml servings in the 400ml Yazoo Chocolate bottle, while the UFIT Chocolate listing says to refrigerate after opening and drink within 24 hours. |
Common buying mistakes
-
Assuming every protein claim means a similar amount
Arla Foods UK and UFIT list 26g and 25g protein respectively in their Chocolate bottles. Using Tesco Groceries’ per-100ml figures, the listed 400ml Yazoo Chocolate and FRijj Strawberry bottles work out to approximately 12.8g and 15.2g respectively.
Compare grams for the amount you intend to drink. If bottles differ in size, also compare their labelled values on a consistent basis.
-
Checking protein but overlooking sugars
For the specific products listed by Tesco Groceries, Yazoo Chocolate contains 8.6g sugars per 100ml and FRijj Strawberry contains 10.1g per 100ml. A protein statement on the front does not tell you the sugars in the drink.
Read the nutrition panel for sugars and energy alongside protein, using the same portion basis for each product.
-
Treating lactose-free as milk-free
Arla Foods UK describes its Protein Chocolate shake as lactose-free but declares milk as an allergen. The NHS distinguishes lactose intolerance from food allergy.
If you have a milk allergy, do not use a lactose-free claim to judge whether a drink is suitable. Read its milk-allergen declaration.
-
Relying on an online listing instead of the pack
Ingredients, nutrition and directions after opening matter to different buying decisions; the pack in hand is the one you will consume.
Check its ingredients, allergen statement, nutrition panel, date and storage instructions before buying or drinking it.
Brand and product-line references
These examples illustrate differences between particular protein drinks and ordinary flavoured milkshakes; they do not describe every product sold under each brand.
Arla Protein
Its Chocolate Flavoured Shake is a ready-to-drink dairy protein option in a 482ml bottle.
- Arla Foods UK lists 26g protein per bottle and describes it as lactose-free at less than 0.01g lactose per 100g.
- The same product declares milk as an allergen. Lactose-free does not mean suitable for a milk allergy.
UFIT
Its Chocolate product is a ready-to-drink protein milkshake in a 330ml bottle.
- UFIT lists 25g protein and 158kcal per Chocolate bottle.
- ASDA Groceries lists milk and oats in the product’s allergen information; check the current label if either matters to you.
Yazoo
The Chocolate Milk Drink is an ordinary flavoured milk drink rather than one of the dedicated protein shakes compared here.
- Tesco Groceries lists 3.2g protein per 100ml for the Chocolate drink.
- The same listing gives 8.6g sugars per 100ml and two 200ml servings in its 400ml bottle. Check whether you intend to drink one serving or the whole bottle.
FRijj
The Strawberry 400ml product is a conventional flavoured milkshake.
- Tesco Groceries lists 3.8g protein per 100ml for this Strawberry product.
- The same listing gives 10.1g sugars per 100ml. Compare its full-bottle nutrition with a dedicated shake if protein amount is your main criterion.

Questions about choosing a milkshake
Does a standard milkshake provide as much protein as a dedicated shake?
Not in these particular examples. Arla Foods UK lists 26g protein per Chocolate shake bottle and UFIT lists 25g per Chocolate bottle. From Tesco Groceries’ per-100ml figures, the listed 400ml Yazoo Chocolate and FRijj Strawberry bottles work out to approximately 12.8g and 15.2g respectively. Compare the product and portion you would actually drink.
Is a lactose-free dairy shake suitable for someone with a milk allergy?
A lactose-free claim does not establish that a shake is milk-free. Arla Foods UK labels its Protein Chocolate shake lactose-free but declares milk as an allergen. Check the allergen declaration rather than using lactose wording to assess a milk allergy.
Can a protein milkshake replace a varied diet?
A bottled shake is one food or drink, not a substitute for dietary variety. NHS guidance describes a varied diet across food groups; if you have a medical condition or special dietary needs, seek advice from your doctor or a registered dietitian.
How long can I keep a protein shake after opening it?
Follow the directions for the particular product. ASDA Groceries’ listing for UFIT Chocolate says to refrigerate after opening and drink within 24 hours, while Arla Foods UK gives three days after opening for its Protein Chocolate shake. Check the current bottle before storing a remainder.
