If lactose is the issue and you can consume cow's milk, lactose-free dairy milk can be part of a post-gym snack; compare its protein per serving with the rest of what you plan to eat. Tesco Groceries lists 5.9 g protein per 200 ml of its lactose-free skimmed drink. If you have a cow's-milk allergy, lactose-free dairy is still milk: Gloucestershire Hospitals NHS Foundation Trust advises avoiding milk products, so check the allergen information on a milk-free alternative instead.
If lactose causes symptoms but cow's-milk protein is suitable for you, lactose-free dairy milk offers a familiar drink or smoothie base. Check the lactose claim and current ingredients, then compare protein per serving and the fat level you want for your snack.
Milk can contribute protein without necessarily being the whole snack. Compare the amount in the serving you will drink with any other food you plan to have; Tesco Groceries lists 5.9 g per 200 ml for its lactose-free skimmed drink.
A cow's-milk allergy calls for a different choice from lactose-free dairy milk. Gloucestershire Hospitals NHS Foundation Trust advises avoiding milk products for a milk allergy. Check the ingredients and allergen information of a milk-free alternative, including whether it contains another allergen you need to avoid.
Decide whether the restriction concerns lactose or milk itself before comparing the nutrition and pack format of drinks that meet it.
| Priority | What to check | Your needs |
|---|---|---|
| Lactose | Read the lactose-free claim and ingredients on the exact carton. Check that it is the dairy format you want. | I want to reduce lactose while keeping cow's milk as part of my snack. |
| Milk allergen | Check the current ingredient list and allergen information. Lactose-free dairy milk still contains milk; a milk-free drink may contain other allergens. | If I must avoid milk, I need a milk-free product rather than one that is only lactose-free. |
| Protein per serving | Compare the labelled serving size as well as protein per 100 ml or per 100 g. Tesco Groceries lists 5.9 g protein per 200 ml of its lactose-free skimmed drink. | When the drink is one part of my post-gym snack, I want to know how much protein my actual serving contributes. |
| Fat and energy | Compare fat, saturates and energy on each product's stated label basis. Keep per-100-ml and per-100-g figures distinct. | I may prefer skimmed, semi-skimmed or whole milk depending on what else is in the snack. |
| Pack and storage | Check the pack size and its storage instructions, particularly what to do after opening. | A single drink to take with me calls for a different pack from one I plan to use for several snacks. |
Lactose-free dairy milk remains a milk product. Waitrose & Partners explicitly says its listed Arla LactoFREE whole milk drink is not suitable for people with a milk allergy.
For lactose intolerance, check the lactose claim. For a milk allergy, choose a suitable milk-free product and read its current allergen information.
Serving size changes how much protein the drink contributes. Tesco Groceries lists 5.9 g per 200 ml of its lactose-free skimmed drink; that figure does not describe any food eaten alongside it.
Check protein for the amount you will drink and consider the drink alongside the other components of your snack.
Tesco Groceries lists 0.1 g fat per 100 ml for its skimmed drink, while Sainsbury's lists 3.8 g per 100 g for its Everyday whole drink. The units differ, so the figures should not be treated as a like-for-like numerical comparison.
Read each carton's fat, saturates and energy information, and compare products on a common stated basis where one is available.
Ingredients, allergen information and storage instructions can change. An older product page may not describe the carton in your hand.
Check the current pack before buying or consuming the drink, particularly when avoiding an allergen.
These listings illustrate dairy choices and label details to compare; they do not establish which products a particular shop currently has in stock.
A lactose-free cow's-milk range with whole, semi-skimmed and skimmed options in UK supermarket listings.
Tesco's lactose-free skimmed dairy drink is a cow's-milk option for shoppers comparing lower-fat cartons.
Its Everyday lactose-free whole dairy drink is an option for shoppers who prefer whole milk in their snack.

The three 300ml bottles offer smaller individual packs for a post-gym drink. This is a soy drink rather than lactose-free dairy milk; it contains soya, so check the current pack's full allergen information before buying if you have an allergy.

The 1L format is an option if you plan to pour more than one serving. It is a soy drink, not lactose-free dairy milk, and contains soya; follow the pack's storage directions after opening and check its full allergen information if you have an allergy.
No: lactose-free dairy milk still contains milk. Gloucestershire Hospitals NHS Foundation Trust advises avoiding milk products for a milk allergy, and the Arla and M&S listings warn that their lactose-free products are unsuitable for people with a milk or dairy allergy. Check the current allergen information on a suitable milk-free alternative.
Not necessarily. Tesco Groceries lists 5.9 g protein per 200 ml of its lactose-free skimmed drink. The International Society of Sports Nutrition's 2017 position stand describes a general 20–40 g high-quality-protein serving range in an exercise context, not a requirement for every shopper. Check what your serving contributes alongside the rest of your snack.
Choose among them by comparing the protein, fat, saturates and energy stated for the serving you intend to drink. Tesco Groceries lists 0.1 g fat per 100 ml for its skimmed drink; Sainsbury's lists 3.8 g per 100 g for its whole drink. Keep those different measurement bases in mind, and remember that all three dairy types contain milk.
Check the exact product's current ingredients and allergen information, including allergens other than milk. The UK Food Standards Agency says food businesses must inform customers when any of the 14 regulated allergens are used as ingredients. For a café-made drink, ask about its ingredients before ordering and make clear whether you need to avoid lactose or milk.
Follow the storage and after-opening instructions on the exact carton. If you plan to carry a drink to the gym, check whether you can keep it as directed until you drink it; do not assume every lactose-free milk or milk-free alternative has the same storage requirements.
