Shoppers wanting a small dairy drink
A 200ml carton may fit a plan for one clearly portioned drink around training. Check how the unopened carton should be stored before leaving it in a gym bag.
Who might consider these drinks?
Pack size, ingredients and the amount you plan to drink can make the same no-added-sugar label relevant to different shoppers.
Shoppers comparing sugars, not just claims
No added sugar does not mean sugar-free. Someone keeping track of sugars can compare the nutrition panel for the portion they expect to drink.
Shoppers checking sweeteners and allergens
Ingredients differ between the Yazoo cartons and the Mars bottle. Anyone avoiding particular sweeteners or allergens needs to read the declaration for the exact product.
What should you check before choosing?
Start with the amount you will drink, then compare its nutrition and ingredients. Storage directions matter if the unopened drink will spend time in your bag.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read sugars per 100ml and per serving, then check the number of servings in the container. Tesco lists 9.4g per 200ml for Yazoo Chocolate and 9.2g for Strawberry; Asda lists 13g per 200ml for Mars. | I want to know how much sugar is in the amount I will actually drink, even when the front label says no added sugar. |
| Pack and storage | Compare Yazoo's 200ml cartons with Mars's 400ml, two-portion bottle. Asda lists ambient storage for Mars; check the unopened-carton directions on Yazoo's pack before relying on room-temperature storage. | A smaller carton suits me if I plan to drink one 200ml portion. If I choose a bottle, I need to decide whether I will drink one portion or both. |
| Snack purpose | Compare protein and carbohydrates for the portion you intend to have. Tesco lists 6.6g protein per 200ml Yazoo Chocolate carton and 6.0g for Strawberry; Asda lists 7.0g per 200ml Mars portion. | For a drink around exercise, I want its portion and nutrition to fit what else I am eating, rather than choosing by the sugar claim alone. |
| Ingredients | Tesco describes the Yazoo cartons as having no artificial sweeteners. Asda lists acesulfame K and sucralose in Mars, along with milk and barley; check the exact pack for allergens. | I may prefer to avoid certain sweeteners or need to check whether a dairy drink's ingredients are suitable for me. |
Common buying mistakes
-
Reading “no added sugar” as “sugar-free”
Milk drinks can still contain naturally occurring sugars. Tesco lists 9.2–9.4g sugars per 200ml across the two Yazoo flavours, while Asda lists 13g per 200ml for Mars.
Compare the sugars line for the amount you expect to drink, not just the claim on the front.
-
Assuming the sweeteners are the same
Tesco describes both Yazoo cartons as having no artificial sweeteners, whereas Asda lists acesulfame K and sucralose in Mars.
Read the ingredients list if sweetener choice affects which drink you buy.
-
Treating a 400ml bottle as a 200ml portion
Asda lists two 200ml portions in the Mars bottle. Nutrition figures stated per portion describe only half the container.
Check the serving count and consider how much of the bottle you intend to drink.
-
Overlooking milk and other allergens
The Yazoo drinks are lactose-reduced milk drinks, not milk-free drinks. Mars lists milk and barley. The NHS distinguishes lactose intolerance from milk allergy.
If you have a milk allergy, do not treat “lactose-reduced” as an indication that a drink is suitable; check the allergen declaration on the exact pack.
Brand and product-line references
These references describe particular drinks or mixes, not every product made by each brand.
Yazoo
Tesco lists Yazoo No Added Sugar Chocolate and Strawberry as lactose-reduced UHT milk drinks in packs of six 200ml cartons.
- Both listings state no artificial sweeteners; the smaller carton provides a clearly defined 200ml portion.
- Both drinks contain milk and list naturally occurring sugars. Check the carton for current ingredients and storage directions.
Mars
Asda lists Mars Chocolate Milk Shake Drink as a no-added-sugar, ambient-storage drink in a 400ml bottle.
- The label divides the bottle into two 200ml portions, making it possible to compare nutrition per portion with a smaller carton.
- Asda lists 13g sugars per 200ml, acesulfame K and sucralose, and the allergens milk and barley.
Tesco
Tesco lists its own No Added Sugar Strawberry and Chocolate Flavoured Milkshake Mix products alongside ready-to-drink milk drinks.
- A mix is an option to consider when you can prepare a drink before leaving.
- A mix is not an unopened ready-to-drink gym-bag milkshake. Follow its preparation directions and check the nutrition of the finished drink.

Questions about gym-bag milkshakes
Does no added sugar mean a milkshake is sugar-free?
No. Tesco lists 9.2g sugars per 200ml for Yazoo Strawberry and 9.4g for Chocolate, while Asda lists 13g per 200ml for Mars. Check the nutrition panel for the amount you plan to drink.
Which of these drinks takes up less room in a gym bag?
A 200ml Yazoo carton is smaller than the 400ml Mars bottle. Yazoo describes its cartons as suitable for carrying in a bag; the Mars bottle contains two 200ml portions. Check storage directions as well as size before packing either drink.
Should I have a milkshake before or after exercise?
Choose the timing according to the role you want the snack to play and what else you are eating. University College London Hospitals NHS Foundation Trust discusses carbohydrate-and-protein snacks around exercise, but a no-added-sugar label alone does not establish that a particular drink fits your activity or circumstances.
Is a lactose-reduced milkshake suitable for someone with a milk allergy?
Do not assume so: the Yazoo lactose-reduced drinks still contain milk, and Mars also lists milk. The NHS distinguishes milk allergy from lactose intolerance. Check the exact pack's allergen declaration and seek appropriate clinical advice for individual allergy concerns.
Can I keep an unopened milkshake in my gym bag?
Follow the storage directions for the exact drink. Asda lists ambient storage for the Mars bottle. Tesco describes the Yazoo cartons as UHT, but check their pack directions before relying on room-temperature storage; after opening, Tesco instructs refrigeration and consumption within three days.
