Choose certified organic lactose-free dairy milk if you want organic production, can have cow’s milk and want to use milk as one source of protein: Arla LactoFREE Organic Semi Skimmed Milk Drink lists 3.4g protein per 100g. If lower fat matters more than organic status, compare skimmed lactose-free dairy drinks; if you need to avoid milk or follow a vegan diet, choose a dairy-free drink instead and check its ingredients.
If you can have cow’s milk but want to avoid lactose and choose an organic product, check the certification details on the particular carton. Arla’s organic semi-skimmed lactose-free drink is one example listed by Sainsbury’s with Soil Association Organic certification.
If milk is one part of your higher-protein eating pattern, compare nutrition panels on the same per-100g basis. Arla lists 3.4g protein and 1.5g fat per 100g for its organic semi-skimmed drink; Sainsbury’s lists 3.4g protein and less than 0.5g fat per 100g for its lactose-free skimmed drink.
Lactose-free cow’s milk still contains milk. If you need a dairy-free or vegan drink, check the ingredients and allergens of a plant-based alternative instead. Waitrose lists an organic Alpro soya drink that is dairy-free and contains 3.3g protein per 100ml.
Start with whether the drink can contain milk, then compare organic certification and nutrition on the pack size and serving you expect to use.
| Priority | What to check | Your needs |
|---|---|---|
| Milk and allergens | Read the ingredients and highlighted allergens. Lactose-free cow’s milk can still contain milk; a soya drink contains soya. | “I need to avoid lactose, but can I have milk?” If milk itself must be avoided, I’ll look for a dairy-free drink and check its allergen declaration. The NHS distinguishes lactose intolerance from food allergy. |
| Protein | Compare protein using the same unit on each nutrition panel, then consider the amount you will use. Arla’s organic semi-skimmed and Sainsbury’s skimmed lactose-free dairy drinks each list 3.4g per 100g; Waitrose lists 3.3g per 100ml for Alpro’s organic soya drink. | “Milk is one part of my protein intake.” I want to know what my usual portion contributes rather than treating an organic or lactose-free label as a protein claim. |
| Organic status | Check that the specific product is labelled organic and inspect its certification information. UK government guidance from the Department for Environment, Food & Rural Affairs describes organic production and certification requirements. | “Organic production matters to me.” I’ll check the particular carton rather than assume every lactose-free product from the same brand is organic. |
| Fat and energy | Compare like-for-like per-100g figures. Sainsbury’s lactose-free skimmed drink lists less than 0.5g fat and 29kcal; M&S lactose-free whole milk lists 3.8g fat and 61kcal. | “I’m choosing between skimmed and whole milk.” If lower fat is my priority, I’ll compare the nutrition panels alongside protein instead of assuming whole milk provides more protein. |
| Storage | Check refrigeration and use-after-opening instructions on the current pack. M&S says its Made Without Lactose Whole Milk should be consumed within three days of opening. | “Will I finish an opened carton in time?” I’ll choose a quantity that fits how I use milk in drinks, cereal or cooking. |
Lactose-free cow’s milk can still contain milk proteins. The NHS distinguishes lactose intolerance from food allergy, and the Arla and M&S dairy products identify milk as an allergen or warn against use for milk allergy.
If you need to avoid milk, choose a dairy-free product and check its allergen declaration rather than relying on a lactose-free label.
Organic certification concerns production and labelling, not a guaranteed protein amount. Arla’s organic lactose-free semi-skimmed drink and Sainsbury’s lactose-free skimmed drink both list 3.4g protein per 100g.
Check organic certification for the production standard you want, and use the nutrition panel separately to compare protein.
In the listed examples, M&S lactose-free whole milk has 3.2g protein and 3.8g fat per 100g; Sainsbury’s lactose-free skimmed drink has 3.4g protein and less than 0.5g fat per 100g.
If lower fat is the aim, compare skimmed and semi-skimmed options before choosing whole milk for its flavour or energy content.
An opened carton may need to be used sooner than you expect: M&S specifies three days after opening for its Made Without Lactose Whole Milk.
Check the current carton’s storage directions and choose a quantity you are likely to use within that period.
These product and range examples show what to compare; a retailer’s listing does not make every product in its range organic or dairy-free.
Its Organic Semi Skimmed Milk Drink is a lactose-free cow’s-milk product listed by Sainsbury’s with Soil Association Organic certification.
Tesco’s lactose-free milk category lists Arla LactoFREE alongside Tesco own-label skimmed and semi-skimmed dairy drinks.
Sainsbury’s lists both Arla’s organic lactose-free semi-skimmed drink and its own Everyday Lactose Free Skimmed Dairy Drink.
M&S lists Made Without Lactose whole and semi-skimmed cow’s-milk products.
Waitrose lists both Arla lactose-free semi-skimmed dairy milk and an Alpro organic, dairy-free soya drink.
This soya-drink option is relevant if you are considering an organic, dairy-free alternative to lactose-free cow’s milk.

A soya drink to consider when cow’s milk is not the right choice. It contains soya; check the current pack for its nutrition, ingredients and allergen information, particularly if you are using it in place of dairy milk.
No. Lactose-free cow’s milk can still contain milk proteins; Arla’s organic lactose-free product contains milk. The NHS distinguishes lactose intolerance from food allergy. If you need to avoid milk, choose a dairy-free product and check its allergen declaration.
Check the organic certification information for that specific product. The Department for Environment, Food & Rural Affairs’ UK guidance sets out organic production and certification requirements; a lactose-free label alone does not establish organic status.
No protein advantage follows from the lactose-free label alone. Arla’s organic semi-skimmed and Sainsbury’s skimmed lactose-free dairy drinks each list 3.4g protein per 100g. Compare the current nutrition panels and the quantity you intend to use.
Compare protein, fat and energy against what you want from the drink. Sainsbury’s lactose-free skimmed drink lists 3.4g protein and less than 0.5g fat per 100g; M&S lactose-free whole milk lists 3.2g protein and 3.8g fat per 100g. If you have an individual protein target from a clinician or dietitian, use that advice when planning your overall intake.
Follow the instructions on the particular carton. M&S says its Made Without Lactose Whole Milk should be refrigerated and consumed within three days of opening; do not assume the same period applies to every drink.
