Choose an energy drink multipack by caffeine per can and sugar variant before deciding how many cans to buy. Red Bull states that its Original 250ml can contains 80mg caffeine, while Monster lists 160mg in its Original and Zero Sugar 500ml cans; a larger can is not a like-for-like choice if you want less caffeine in each opened can. Count caffeine from other drinks and foods as well.
If you expect to open one can during a session, its declared caffeine amount matters alongside its volume. Red Bull lists 80mg in a 250ml Original can; Monster lists 160mg in a 500ml Original can. Check the exact variant rather than applying either figure to a whole brand.
A sugar-free variant lets you make a separate choice about sugar, but it still needs a caffeine check. Monster states that its Zero Sugar 500ml can contains 0g sugar and 160mg caffeine.
Check both the number of cans and the amount in each one. A multipack is most useful for planning servings when its can size, sugar variant and caffeine declaration fit the people who will drink it.
Start with the exact can you would open, then check the sugar variant and pack quantity.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Read the caffeine declaration for the exact variant and can volume. Red Bull lists 80mg per 250ml Original can; Monster lists 160mg per 500ml Original or Zero Sugar can. Include caffeine from other sources when considering a day’s intake. | I want to know how much caffeine is in the can I am likely to open, not just how large the multipack is. |
| Sugar variant | Check the product name and sugar declaration per can. Red Bull states 27g sugars in its Original 250ml can; Monster states 55g in Original and 0g in Zero Sugar per 500ml can. | If I choose a sugar-free drink with my snacks, I still want to check its caffeine separately. |
| Can and pack size | Check the volume of each can and the number of cans. Do not treat a 250ml can and a 500ml can as the same serving simply because both come in multipacks. | I want enough individual cans for several sessions without assuming I will drink a larger can each time. |
| Who will drink it | Read the exact pack warning before stocking a shared household. The Department of Health and Social Care and Department for Education announced an England ban on sales of high-caffeine energy drinks to under-16s from April 2027. The NHS advises no more than 200mg caffeine a day during pregnancy, counting all sources. | If different people may take a can, I need to check who the drink is intended for rather than treating the multipack as suitable for everyone. |
Monster states 160mg caffeine in its Original 500ml can, compared with Red Bull’s stated 80mg in an Original 250ml can. Opening one of each does not mean consuming the same amount of caffeine.
Decide what caffeine amount you want to account for per opened can, then check the declaration on the exact multipack.
Monster states that its Zero Sugar 500ml can has 0g sugar but 160mg caffeine—the same stated caffeine amount as its Original 500ml can.
Make separate checks for sugar and caffeine, even when two variants share a brand and can size.
A multipack kept with gaming snacks may be accessible to people for whom its caffeine warning matters. England’s announced under-16 sales restriction is scheduled for April 2027; it should not be described as a current UK-wide rule.
Check the exact pack warning and who will use the drinks. During pregnancy, the NHS advises counting caffeine from all sources against its 200mg daily limit.

No—not for the cited Monster variants. Monster states that both its Zero Sugar and Original 500ml cans contain 160mg caffeine, although their stated sugar amounts are 0g and 55g respectively. Check the caffeine declaration on any other variant separately.
Choose by the drink and caffeine amount you intend to have in one opened can, not volume alone. Red Bull states 80mg caffeine in its Original 250ml can, while Monster states 160mg in its Original 500ml can; other products and variants need their own label check.
Count caffeine from the energy drink and all other sources. The NHS advises no more than 200mg caffeine a day during pregnancy; Monster states 160mg in one Original 500ml can, before any caffeine from tea, coffee or other foods and drinks is counted.
The Department of Health and Social Care and Department for Education announced that sales of high-caffeine energy drinks to under-16s in England will be banned from April 2027. This is an announced England measure, not a statement that the restriction is already in force or that the same rule applies throughout the UK.
