Adults planning to keep a case at home
A multipack can serve identified adult consumers who have space to store it separately from children's drinks. Check the caffeine in one can before deciding how many cans to buy.
Who is this purchase for?
Adults choosing between sugared and zero-sugar drinks
Sugar and caffeine are separate checks. Monster Energy UK states 0g sugar and 160mg caffeine for its cited 500ml Zero-Sugar product, so that sugar choice does not make this example a lower-caffeine one.
Households with children or someone who is pregnant
Do not treat high-caffeine cans as drinks to share around the household; check the warning on the exact pack and keep it apart from children's drinks. NHS guidance says caffeine intake during pregnancy should not exceed 200mg a day, including caffeine from other drinks and foods.
What should you compare?
Start with what is in a single can, then choose a case count and flavour that make sense for the adults who will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Read the caffeine statement alongside can volume. Red Bull UK states 80mg per 250ml Energy Drink can; Monster Energy UK states 160mg per cited 500ml Original and Zero-Sugar can. Check the exact variant rather than applying those figures to a whole brand. | I want to know the amount in one can, particularly if the adults drinking it also have coffee, tea or other caffeine sources. |
| Sugar and ingredients | Compare the sugar declaration and ingredient list for the exact formula. Monster Energy UK states 55g sugar for its cited 500ml Original product and 0g for its cited 500ml Zero-Sugar product; both state 160mg caffeine. | If I choose zero sugar, I still need to check caffeine separately. I also want to know which sweeteners are in the flavour I am ordering. |
| Who can access the case | Read the pack warning and plan where the cans will be kept. Relentless warns that its Guava drink is not recommended for children or pregnant or nursing women. NHS guidance sets a 200mg daily caffeine limit during pregnancy. | In a household with children, I need the cans kept apart from drinks they can take for themselves. |
| Pack and can size | Check both the can count and volume: the Joybuy listings represented here include 250ml and 500ml cans in different case sizes. Confirm the exact flavour, formula and best-before date for the case you select. | I would rather choose a count the intended adults will use than commit to a larger case of an unfamiliar flavour. |
Mistakes to avoid
-
Choosing by can count alone
A 250ml can and a 500ml can are different serving sizes. Red Bull UK states 80mg caffeine in its 250ml Energy Drink, while Monster Energy UK states 160mg in each cited 500ml Original and Zero-Sugar can.
Compare caffeine per can before choosing a case size, and account for other caffeine the intended adults consume.
-
Reading “zero sugar” as “less caffeine”
Monster Energy UK states 0g sugar but 160mg caffeine for its cited 500ml Zero-Sugar product. The sugar and caffeine declarations answer different questions.
Check both fields, along with the sweeteners and flavour, on the exact pack.
-
Leaving a high-caffeine case among family soft drinks
A multipack format does not make every can suitable for every household member. The warning on Relentless Guava, for example, says it is not recommended for children or pregnant or nursing women.
Choose the case for intended adult consumers, read its own warning and store it separately from children's drinks.
-
Assuming every “energy” drink has the same formula
Lucozade describes its Energy range as containing glucose, while the cited Red Bull and Monster products have their own stated caffeine and sugar values. The category name does not establish an equivalent ingredient profile.
Compare the ingredients, nutrition information, caffeine statement and can volume of the exact products before substituting one case for another.
Brand and range references
Red Bull
Its 250ml can format provides a clear unit for comparing the cited Energy Drink's caffeine amount.
- Red Bull UK states 80mg caffeine per 250ml Energy Drink can; the cited Joybuy listings include 12- and 24-can Red Bull formats.
- Check the exact sugar variant and pack warning. A smaller can is not a reason to make the case available to children.
Monster
The cited 500ml Original and Zero-Sugar products illustrate a sugar choice that needs a separate caffeine check.
- Monster Energy UK states 55g sugar for its cited Original can and 0g for its cited Zero-Sugar can.
- Both cited 500ml products state 160mg caffeine per can; confirm the figures for any other Monster variant.
Lucozade Energy
Lucozade describes this range as glucose-containing sparkling drinks.
- It offers a distinct formula to consider when comparing products labelled “energy”.
- Check the ingredients, sugar, caffeine and warnings on the exact multipack rather than assuming they match a cited high-caffeine can.
Relentless
Relentless lists UK supermarket retailers for its range, but a retailer listing does not identify the contents of a particular multipack.
- Its Guava product page gives an explicit warning about intended consumers.
- Relentless says Guava is not recommended for children, people sensitive to caffeine, pregnant women or nursing women. Check the selected pack's own format and label.

Questions about household multipacks
Can an energy-drink case be shared like a family soft-drink pack?
Do not treat a high-caffeine case as a drink for everyone in the household. Choose it for intended adult consumers, read the exact pack warning and keep it separately if children can access the fridge or cupboard.
Does zero sugar mean less caffeine?
No, not in the cited Monster examples: Monster Energy UK states 0g sugar and 160mg caffeine for its 500ml Zero-Sugar product, while its cited 500ml Original also states 160mg caffeine. Check both declarations on the exact variant you buy.
How do the cited 250ml and 500ml cans compare for caffeine?
Red Bull UK states 80mg caffeine in a 250ml Energy Drink can; Monster Energy UK states 160mg in each of its cited 500ml Original and Zero-Sugar cans. Those are product-specific figures, not a rule for every drink of either size.
What matters if someone in the household is pregnant?
Check the drink's warning and caffeine amount rather than treating the case as a shared purchase. NHS guidance says caffeine intake during pregnancy should not exceed 200mg a day and notes that energy drinks are one of several caffeine sources.
