Households sharing a bottle
A large bottle can be divided between people who train on different days or at different times. Plan the portions and check that everyone can use the opened bottle within its stated storage period.
Choose a large bottle when several people will share it in measured portions and finish it within the label’s storage period; choose a multipack when separate, ready-to-drink portions matter more. Neither format tells you whether a milkshake meets your post-workout needs: compare the protein and sugars in the amount you will actually drink, alongside what you eat after exercise.
The useful pack size depends on how many people will drink it, the portions they want and what happens to the pack once it is opened.
A large bottle can be divided between people who train on different days or at different times. Plan the portions and check that everyone can use the opened bottle within its stated storage period.
An individual bottle or can gives one person a defined volume without opening a shared bottle. Compare its protein and carbohydrate figures with the rest of the food and drink planned after exercise.
A smaller container makes the volume easy to see, but it does not establish its total sugar content. Check the nutrition panel for the exact flavour and pack rather than relying on a no-added-sugar description.
Start with the volume you would drink, then compare its nutrition information and the pack’s storage instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Read the grams of protein for the volume you will drink, not just a front-of-pack claim. Sainsbury’s lists 6.5g per 200ml serving of Yazoo Chocolate 1L; Asda lists 3.7g per 100ml of FRijj Chocolate 330ml. | I want to know what the drink contributes alongside my post-workout food. The Association for Nutrition gives a guide of 0.25–0.4g protein per kilogram of body weight for a post-workout meal or snack, depending on exercise type and intensity. |
| Carbohydrate and sugars | Compare carbohydrate and total sugars for the portion consumed. Sainsbury’s lists 17.3g sugars per 200ml of Yazoo Chocolate 1L; Asda lists 11.4g per 100ml of FRijj Chocolate 330ml. Check the exact multipack label separately. | After a long or repeated session, I may be planning food and drink for quick refuelling. The British Dietetic Association’s May 2026 sport and exercise guidance distinguishes that situation from a general fitness programme, where carbohydrate needs can be met through a normal diet. |
| Portion format | Check the stated serving size against the container size. Sainsbury’s labels Yazoo Chocolate 1L as five 200ml servings; Tesco lists a separate Yazoo No Added Sugar Chocolate pack of six 200ml bottles. | If several of us will share, measured pours could work. For separate trips or training days, I would rather take an individual bottle. |
| Storage after opening | Read the instructions for the exact product and allow for refrigeration. The Sainsbury’s Yazoo Chocolate 1L and Asda FRijj Chocolate 330ml listings both say to refrigerate after opening and consume within three days. | A large bottle makes sense for us only if we will finish it within the time stated on its label. |
| Milk ingredients | Check the current ingredients and allergen declaration for the chosen flavour. Asda’s FRijj Chocolate listing declares milk; a no-added-sugar description is not an allergen statement. | Someone drinking it may need to avoid milk or check whether lactose-containing dairy suits them. The NHS distinguishes milk allergy from lactose intolerance; they are not interchangeable. |
The protein figure applies to a stated volume. Sainsbury’s lists 6.5g in a 200ml serving of Yazoo Chocolate 1L, while the Association for Nutrition’s post-workout guide varies with body weight and the exercise performed.
Check the amount in the portion you will drink and consider the protein in the food you plan to eat with it.
Sainsbury’s labels Yazoo Chocolate 1L as five servings and says to refrigerate it after opening and drink it within three days.
Consider how many people will have a serving during that period before choosing one shared bottle over individual portions.
An unfinished shared bottle may mean discarding the remainder when its stated storage period ends.
Sainsbury’s gives sugars per 200ml for Yazoo Chocolate 1L, whereas Asda gives them per 100ml for FRijj Chocolate 330ml. A full bottle and a measured serving are different quantities.
Use the same volume basis when comparing labels, then calculate the figures for the amount you expect to drink.
The NHS explains that lactose intolerance and food allergy are different; a food allergy can be life threatening. Asda’s FRijj Chocolate listing declares milk.
Check the allergen declaration on the exact pack. Do not treat a lactose-related or no-added-sugar description as evidence that a dairy drink is suitable for someone with a milk allergy.
These examples show how formats differ; nutrition and storage details belong to the named products, not every drink from the same brand or retailer.
Sainsbury’s lists Yazoo Chocolate Milk Drink in a 1L shared bottle, while Tesco lists a distinct No Added Sugar Chocolate pack of six 200ml bottles.
The FRijj Chocolate Milkshake listed by Asda is a 330ml individual bottle, not a family-size bottle.
Tesco lists Mars Chocolate Flavoured Milk Drink No Added Sugar in a 400ml format.
Tesco’s milkshake listings include its own-label 1L chocolate flavoured milk as well as branded bottles and multipacks.
These are individually portioned milkshake-style protein drinks sold in multipacks. They offer a different format from a shared 1L bottle: check each drink’s nutrition and serving size against what you plan to have after exercise.

Eight separate bottles suit a household planning drinks for different occasions. At 500ml each, check whether a whole bottle is the portion you want, and compare the current nutrition label with your post-workout food. Contains milk.

Eight 250ml cans provide separate portions without measuring from a shared bottle. Check the current nutrition label for the amounts in one can. Contains milk; check the allergen declaration if milk is a concern.

Eight 330ml bottles give household members separate portions for different occasions. Compare protein, carbohydrate and total sugars on the current label for the amount you intend to drink. Contains milk.

Twelve individual 330ml bottles suit separate drinking occasions rather than pouring from a family-size bottle. Check the current label for protein, carbohydrate and sugars per bottle before comparing it with other packs. Contains milk.
Not necessarily on its own. The Association for Nutrition gives a guide of 0.25–0.4g protein per kilogram of body weight for a post-workout meal or snack, depending on exercise type and intensity. Sainsbury’s lists 6.5g protein per 200ml serving of Yazoo Chocolate 1L; Asda’s figures for FRijj Chocolate work out at about 12.2g per 330ml bottle. Consider the drink alongside the food you will eat.
A large bottle makes sense when people will share measured servings and finish it within its stated storage period. Sainsbury’s labels Yazoo Chocolate 1L as five 200ml servings and instructs shoppers to refrigerate it after opening and drink it within three days.
No. The phrase does not state the total sugars in a serving; milk naturally contains lactose. Check the total sugars figure and ingredients on the exact pack you intend to buy.
Check the ingredients and the individual product rather than assuming every dairy milkshake will suit them. The NHS says lactose intolerance can cause symptoms after consuming foods containing lactose. It is different from milk allergy, so a lactose-related description cannot replace an allergen check.
Do not assume it is. Asda’s FRijj Chocolate listing declares milk, and the NHS distinguishes potentially serious food allergy from lactose intolerance. Check the exact pack’s allergen declaration before choosing a drink for someone who must avoid milk.
