People using milk regularly
If milk goes into your drinks, cereal, porridge or cooking, protein per 100ml helps you compare what each choice contributes at your usual serving size.
Who is this choice for?
Whole-milk drinkers comparing nutrition
If you prefer whole milk but are planning your overall intake, check energy and fat alongside protein rather than choosing by the protein figure alone.
People considering lactose-free or filtered milk
Lactose content and storage instructions may decide the choice. Neither a lactose-free label nor filtration, by itself, tells you that a milk has more protein.
What should you check?
Start with the nutrition panel for the amount you will actually use, then check whether storage or lactose requirements change which product is suitable.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Compare grams per 100ml on the same basis. Waitrose & Partners lists 7g for SuperNutrio high-protein whole milk and 3.5g for Essential whole milk; check how much milk you use per serving. | I want more protein from the milk I already use, without assuming that every whole milk provides the same amount. |
| Energy and fat | Read energy and fat per 100ml as well as protein. Waitrose & Partners lists 81kcal for SuperNutrio and 66kcal for Essential whole milk per 100ml; compare the current labels for your chosen products. | If I use milk several times a day, I want to account for it in my wider eating plan. |
| Lactose and allergens | Check the lactose statement and the milk-allergen declaration separately. Waitrose & Partners lists Arla LactoFREE whole milk drink as containing less than 0.03% lactose and says it is not suitable for people with a milk allergy. | I need to distinguish avoiding lactose from avoiding milk proteins before choosing a dairy product. |
| Storage life | Compare unopened-life claims, use-by dates and instructions after opening for the exact product. Arla says Cravendale filtered whole milk stays fresh for up to three weeks unopened; ASDA lists 3.4g protein per 100ml for its Cravendale product. | Milk sometimes stays in my fridge for several days, so storage instructions matter more to me than a higher protein concentration. |
Buying pitfalls
-
Assuming all whole milk has the same protein level
The difference can matter at the same serving size: Waitrose & Partners lists 7g protein per 100ml for SuperNutrio high-protein whole milk and 3.5g for its Essential whole milk.
Compare the protein line per 100ml on the product you intend to buy, then apply it to the amount you normally use.
-
Using “mature” as a protein claim
“Mature” does not give you a measurable protein value for the whole-milk choices described here. The product labels instead distinguish options such as filtered, lactose-free and high-protein milk.
Use the nutrition panel and storage or suitability information to make the comparison.
-
Confusing lactose-free milk with milk-allergy suitability
Removing or reducing lactose does not remove milk proteins. Waitrose & Partners states that Arla LactoFREE whole milk drink is not suitable for people with a milk allergy.
If milk allergy is relevant, check the allergen declaration rather than substituting lactose-free dairy on that basis.
Relevant milk brands
SuperNutrio
A specifically high-protein whole-milk example for comparing protein from the same volume of milk.
- Waitrose & Partners lists 7g protein and 81kcal per 100ml for its SuperNutrio fresh whole milk product.
- Check energy alongside protein: Waitrose & Partners lists 66kcal per 100ml for its Essential whole milk example.
Cravendale
Filtered whole milk for shoppers interested in the product’s stated unopened storage life.
- Arla says its Cravendale filtered whole milk stays fresh for up to three weeks unopened.
- ASDA lists 3.4g protein per 100ml for its Cravendale whole milk product; filtration should not be read as a high-protein claim.
Waitrose Essential
An ordinary whole-milk reference point when comparing nutrition panels.
- Waitrose & Partners lists 3.5g protein, 66kcal and 3.7g fat per 100ml for its Essential British Free Range Whole Milk.
- Its stated protein per 100ml is lower than that of the SuperNutrio example listed by the same retailer.
Arla LactoFREE
A whole-milk drink to consider when lactose, rather than milk protein, is the suitability question.
- Waitrose & Partners lists less than 0.03% lactose for its Arla LactoFREE whole milk drink.
- The product listing says it is not suitable for people with a milk allergy.
Joybuy milk powder option
This whole-fat milk powder is an option if you are willing to prepare milk from powder rather than buy ready-to-drink fresh whole milk. Compare nutrition for the prepared drink when deciding whether it fits your protein needs.

NIDO Nestle Whole Fat Instant Milk Powder, 900 g
For drinks or cooking when mixing milk from powder suits your routine, this is a 900 g whole-fat instant milk powder, not ready-to-drink fresh milk. Follow the pack’s mixing instructions and compare protein and energy for the prepared serving; check its allergen declaration if milk or soya is a concern.
Common questions
Does “mature” help you choose whole milk for protein?
No protein level follows from the word “mature” for the whole-milk products discussed here. Compare protein per 100ml on the label, then check energy, fat and any storage or lactose requirements that matter to you.
How much protein is in ordinary whole milk?
The examples differ slightly: Waitrose & Partners lists 3.5g protein per 100ml for Essential whole milk, while ASDA lists 3.4g per 100ml for Cravendale filtered whole milk. Check your chosen pack and multiply its per-100ml figure by the amount you use.
Is high-protein whole milk necessarily lower in calories?
No. Waitrose & Partners lists 81kcal per 100ml for SuperNutrio high-protein whole milk, compared with 66kcal per 100ml for its Essential whole milk. Compare both figures for the products and serving sizes you are considering.
Is lactose-free whole milk suitable for a milk allergy?
Not on the basis of its lactose-free label. Waitrose & Partners explicitly says its Arla LactoFREE whole milk drink is not suitable for people with a milk allergy; check the allergen declaration for the exact product.
How long can filtered whole milk be kept?
Follow the use-by date and storage instructions on the particular pack. Arla claims up to three weeks unopened for Cravendale filtered whole milk; Waitrose & Partners states up to one month unopened and seven days after opening for its own filtered whole milk. Those claims are product-specific, not a storage rule for all filtered milk.
