New parents comparing convenient drinks
If you might drink a whole bottle between other tasks, compare its full-bottle sugars and energy as well as the figures per 100ml. A no-added-sugar claim alone does not tell you either total.
Who these choices are for
The useful distinction is whether you are comparing sugars, managing lactose or checking a milk-free restriction; those needs call for different label checks.
Adults limiting lactose
A lactose-reduced milk drink may be relevant if lactose is the issue. It can still contain milk protein, so it is not a substitute for a milk-free product.
Breastfeeding parents following a milk-free exclusion
If a clinician has advised avoiding dairy while your baby is assessed or managed for a reaction to cow’s milk protein, check the ingredients and allergen declaration of the whole drink or mix. Lactose-reduced dairy drinks still contain milk.
What to check before choosing
Start with the dietary restriction, then compare nutrition on the same volume and check how much of the pack you expect to drink.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugars | Compare sugars per 100ml and per bottle or prepared glass. Tesco Groceries lists 4.7g per 100ml for Frijj Chocolate Reduced Sugar and 9.3g per 100ml for Shaken Udder Chocolush; these figures describe those products, not every no-added-sugar or standard milkshake. | I want to know how much sugar is in the drink I will actually have, regardless of its front-label claim. In the Food Standards Agency’s Making Food Better Tracker Survey 2024, 49% of respondents said they actively used traffic-light labels when shopping for food; the survey comprised 611 interviews from 16 September to 23 November 2024, not a survey of new parents choosing milkshakes. |
| Milk and lactose | Read the ingredient and allergen declaration before relying on ‘lactose-reduced’. Tesco Groceries describes Yazoo No Added Sugar Strawberry as lactose-reduced but also declares milk. | If lactose is my concern, I need to distinguish it from a requirement to avoid milk altogether. For a milk-free exclusion, a lactose-reduced dairy drink does not meet that requirement. |
| Portion size | Check the bottle volume, portions per pack and whether nutrition is shown per 100ml or per portion. Tesco Groceries lists two portions in the 400ml Mars No Added Sugar bottle. | A bottle may be more than one stated portion, so I compare the amount I expect to drink rather than assuming the serving figures cover the whole pack. |
| Mixing a drink | For a powder, check both its ingredients and the milk specified for prepared nutrition. Tesco Groceries gives directions using approximately 200ml milk for its No Added Sugar Strawberry Milkshake Mix; its prepared nutrition is based on semi-skimmed milk. | Choosing the liquid myself matters if I want control over the base and glass size. Changing the milk can change the finished drink’s nutrition, but it does not remove any milk ingredient already in the powder. |
| Everyday use | Check the full ingredient and nutrition panels, storage directions and any use warnings. NHS breastfeeding guidance advises a varied diet rather than a special breastfeeding diet for most people. | I want a convenient drink that fits alongside meals, rather than assuming a milkshake covers everything I need. If I am breastfeeding, I also check any product-specific nursing warning before buying. |
Milkshake label pitfalls
-
Reading ‘no added sugar’ as ‘no sugar’
Milk-based drinks can still contain naturally occurring sugars. Tesco Groceries lists 6.5g sugars per 100ml for Mars No Added Sugar and 4.7g per 100ml for Frijj Chocolate Reduced Sugar.
Compare the ‘of which sugars’ figure per 100ml, then check the amount in the bottle or glass.
-
Reading ‘lactose-reduced’ as ‘milk-free’
The NHS distinguishes lactose intolerance from food allergy. Tesco Groceries describes Yazoo No Added Sugar Strawberry as lactose-reduced, but its allergen information still declares milk.
If you need to avoid milk protein, check the ingredients and allergen declaration rather than choosing by lactose wording.
-
Overlooking the number of portions
Tesco Groceries lists two 200ml portions in a 400ml Mars No Added Sugar bottle. Drinking the full bottle means consuming twice the amount shown for one portion.
Work out whether you are comparing one portion or the whole pack before choosing a bottle size.
-
Treating a milkshake as a complete meal
A milkshake’s stated protein or calcium does not, on its own, establish that it replaces a varied diet. NHS breastfeeding guidance advises eating a variety of foods.
Consider the milkshake as part of what you eat and drink, and check its ingredients and portion rather than judging it by one nutrient.

Applied Nutrition Protein Nutrition Shake Strawberries & Cream Flavour, 8 × 330ml
The 330ml bottle size gives you a defined amount to compare with other ready-to-drink shakes. This product contains milk, and its product information advises consulting a qualified health professional before use while nursing; check the current label before choosing it for that use.
No image available
Applied Nutrition Protein Nutrition Shake Double Chocolate Flavour, 8 × 500ml
Compare nutrition for the full 500ml bottle with the amount you expect to drink; a per-100ml figure alone will not describe the whole bottle. The product contains milk, and its information advises consulting a qualified health professional before use while nursing.
No image available
REP Vanilla Flavour Protein Shakes, 8 × 250ml
The 250ml can is a smaller stated portion than the other Joybuy options shown here; compare its full-can label rather than assuming a smaller pack has a lower per-100ml value. It contains milk, and its product information advises pregnant or nursing users to consult a healthcare professional before use.
Questions about milkshake choices
Does ‘no added sugar’ mean a milkshake is sugar-free?
No. Tesco Groceries states that its listed Mars No Added Sugar and Frijj Chocolate Reduced Sugar drinks contain naturally occurring sugars: 6.5g and 4.7g per 100ml respectively. Check total sugars on the nutrition panel and the amount in the portion you will drink.
Can I use a lactose-reduced milkshake for a milk-free diet?
Not if it still contains milk. Tesco Groceries describes Yazoo No Added Sugar Strawberry as lactose-reduced but declares milk as an allergen. Lactose intolerance and milk allergy are different; for a professionally advised milk-free exclusion, check the full ingredients and allergen declaration.
Can a milkshake fit into a breastfeeding routine?
NHS guidance says most people do not need a special diet while breastfeeding and advises eating a variety of foods. Check whether the drink meets your own dietary requirements and read any product-specific nursing warning; a milkshake should not be assumed to replace a varied diet.
How do I compare milkshake bottles of different sizes?
Compare nutrition per 100ml first, then check the volume you expect to drink and the number of portions stated on each pack. Tesco Groceries lists two 200ml portions in the 400ml Mars No Added Sugar bottle, so a whole bottle is twice one stated portion.
Will dairy-free milk make a milkshake powder milk-free?
Only if the powder itself is also suitable for a milk-free diet. Check its ingredient and allergen declaration separately from the liquid you add. Prepared nutrition may also change when you use a different milk from the one specified on the pack.
