Choose ordinary lower-fat milk rather than whole milk if reducing fat is your priority: the NHS recommends lower-fat milk for older children and adults, and NHS Scotland says it contains similar amounts of protein, carbohydrate and calcium. If you want the drink itself to contribute more protein, compare high-protein milk with standard semi-skimmed milk per 100ml and for the portion you intend to drink; the fat level alone does not tell you its protein content.
The useful distinction is whether you mainly want less fat, more protein in one drink, or a pack that fits how often you use milk.
If you prefer cow's milk after training but want less fat than whole milk, compare semi-skimmed, 1% and skimmed options. NHS Scotland says lower-fat milk contains similar amounts of protein, carbohydrate and calcium to whole milk.
If you want the milk itself to provide more protein, check the amount in your intended serving. Tesco Groceries lists 7g protein per 100ml for SuperNutrio high-protein semi-skimmed milk, compared with 3.6g per 100ml for its standard British semi-skimmed milk.
If you make a shake only after some workouts, choose a pack size you can use within its storage instructions. Tesco Groceries states seven days after opening for Cravendale filtered semi-skimmed milk; Waitrose states seven days for its filtered semi-skimmed milk. Follow each pack's use-by date and refrigeration directions too.
Start with the protein in the amount you plan to drink, then compare fat level and whether the pack fits your routine.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per drink | Compare protein per 100ml and for the portion you will drink. Tesco Groceries lists 7g per 100ml for SuperNutrio high-protein semi-skimmed milk and 3.6g for Tesco British semi-skimmed milk. | I want to know how much protein my actual drink contributes, rather than assuming every semi-skimmed milk is alike. |
| Fat level | Compare the fat and saturates on each label. NHS Scotland says lower-fat milk has similar amounts of protein, carbohydrate and calcium to whole milk; the NHS recommends lower-fat milk for older children and adults. | If reducing fat matters to me, I can choose semi-skimmed, 1% or skimmed milk without choosing whole milk for its protein. |
| Pack and storage | Check pack size, use-by date, refrigeration instructions and life after opening. Tesco Groceries and Waitrose each state seven days after opening for the filtered milks described here; follow the instructions on the specific pack. | I only use milk after some training sessions, so I want a pack I can finish within its stated storage period. |
| Milk ingredients | Read the ingredients and allergen declaration on the product you buy. The Food Standards Agency identifies milk as an allergen; a lower fat level does not make cow's milk dairy-free. | If I need to avoid milk, choosing skimmed instead of whole milk does not address that requirement. |
Whole milk has more fat than lower-fat milk, but NHS Scotland says lower-fat versions contain similar amounts of protein, carbohydrate and calcium.
Choose a fat level that suits your preference, then read the protein figure per 100ml if protein in the drink is the deciding factor.
Protein can differ between standard and high-protein semi-skimmed products. Tesco Groceries lists 3.6g per 100ml for its British semi-skimmed milk and 7g per 100ml for SuperNutrio high-protein semi-skimmed milk.
Compare the same volume on both labels and consider what else you will have with the drink after training.
A stated longer life before opening does not tell you how long milk should be kept once opened. The use-by date and refrigeration instructions still matter.
Choose a pack size you expect to finish and follow the specific pack's opened-life directions.
Whole, semi-skimmed and skimmed cow's milk still contain milk, which the Food Standards Agency identifies as an allergen.
If you need to avoid milk, check the ingredients and allergen declaration rather than selecting by fat level.
These examples show differences to check on individual products, not a judgement about everything each brand sells.
Its filtered fresh semi-skimmed milk is an option to examine if opened-life matters more to you than choosing a high-protein product.
Tesco's own-label British semi-skimmed milk provides a standard product to compare with high-protein milk sold in its listings.
The listed M&S semi-skimmed milk is another standard lower-fat product with nutrition figures expressed per 100g.
Waitrose filtered semi-skimmed milk is worth examining if the time between uses affects your choice of pack.
These Morrisons UHT skimmed milk options let you choose between one 1-litre carton and a six-pack of 1-litre cartons. If protein per drink is your priority, compare their on-pack nutrition with any high-protein milk you are considering.

The six-pack suits shoppers who expect to use several cartons. Check the protein for the amount you plan to drink and follow the storage directions on each carton.

A single carton suits shoppers who prefer one 1-litre pack to a multipack. Check the protein for your intended serving and follow the carton's instructions after opening.
Not solely because it is whole milk. NHS Scotland says lower-fat milk contains similar amounts of protein, carbohydrate and calcium, while the NHS recommends lower-fat milk for older children and adults. Choose according to the fat level you want and check the protein in the portion you will drink.
No. NHS Scotland says lower-fat cow's milk contains a similar amount of protein to whole milk. The amount in your drink still depends on the particular product and serving size, so check its nutrition panel.
Consider it when you want more protein from the drink itself. Tesco Groceries lists 7g per 100ml for SuperNutrio high-protein semi-skimmed milk, compared with 3.6g per 100ml for Tesco British semi-skimmed milk. Compare the portion you will drink rather than assuming the same figure applies to every product.
No: skimmed cow's milk still contains milk, which the Food Standards Agency identifies as an allergen. Check the ingredients and allergen declaration of any product you are considering.
Follow the temperature, use-by date and opened-life instructions on the specific pack. Tesco Groceries states seven days after opening for the listed Cravendale filtered semi-skimmed milk, and Waitrose states seven days for its listed filtered semi-skimmed milk; those periods should not be assumed for other products.
