Campers choosing a smaller can
If you want to plan around one can at a time, compare its full caffeine and sugar amounts. Red Bull lists 80mg caffeine in Original 250ml; Monster UK lists 160mg in Original Green 500ml.
Who is choosing these drinks?
The useful comparison changes with the number of people travelling, the number of days away and what each person wants from an individual can.
Campers avoiding sugar
A zero-sugar label answers the sugar question, not the caffeine question. Sainsbury's lists CELSIUS Raspberry Peach as zero sugar with 200mg caffeine per 355ml can.
People buying for a group
Check both the number of cans in a pack and the amount in each can. The product examples include 250ml, 355ml and 500ml formats, which make different individual portions even when several cans are packed.
What should you check before buying?
Start with the amounts in one complete can, then decide how many individual cans the trip calls for.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Compare milligrams in the whole can, not only per 100ml. Red Bull lists 80mg in Original 250ml; Monster UK lists 160mg in Original Green 500ml; Sainsbury's lists 200mg in CELSIUS Raspberry Peach 355ml. Include caffeine from other drinks, food and supplements when planning your day. | I want to know how much caffeine I would have if I finish one can, especially if I am also packing coffee or tea. |
| Sugar | Compare sugars per whole can for the exact variant. Red Bull states 27g in Original 250ml and Monster UK lists 55g in Original Green 500ml; Sainsbury's describes CELSIUS Raspberry Peach 355ml as zero sugar. Check the label of the pack you buy. | Sugar matters to my drink choice, but I do not want to mistake a zero-sugar can for a low-caffeine one. |
| Can and pack size | Check the volume of each can and the number of cans in the pack separately. A multipack changes the quantity you carry, not the caffeine or sugar in an individual can. | For several adults or days away, I want enough separate servings without confusing the pack total with one person's drink. |
| Packing and warnings | Read the product's storage directions and caffeine warning. The Food Standards Agency says camping food that needs chilling should be kept below 5°C; a cool box is unlikely to maintain chilling for an extended trip. | I need drinking water and a suitable plan for chilled food as well as space for canned drinks. |
Packing and buying mistakes to avoid
-
Judging caffeine by can size alone
Monster UK lists 160mg caffeine in its Original Green 500ml can, compared with the 80mg Red Bull lists for Original 250ml. Finishing one of those larger cans means a different caffeine amount, not simply a larger volume of drink.
Compare caffeine in milligrams per complete can, then account for other caffeine you expect to have that day before deciding how many cans to pack.
-
Reading “zero sugar” as “low caffeine”
Sainsbury's lists CELSIUS Raspberry Peach 355ml as zero sugar and containing 200mg caffeine per can.
Use the sugar declaration to compare sugar, and read the caffeine amount and warning separately for the exact variant.
-
Letting the drinks dictate the food-storage plan
Sealed canned drinks do not change the chilling requirements of other camping food. Food Standards Agency guidance says to separate raw and ready-to-eat food and keep food that requires chilling below 5°C.
Pack drinking water and plan appropriate food storage independently of the energy drinks. Check each drink's own storage directions and best-before date.

Treating a future England sales plan as a current UK-wide rule
The Department of Health and Social Care announced in July 2026 that an under-16 sales ban for high-caffeine energy drinks in England was intended for April 2027, subject to Parliamentary approval. That announcement does not establish one current rule across all four UK nations.
If shopping for a trip involving under-16s, check the current rules where you buy and the retailer's age-verification requirements.
Brand and product-line references
These named products illustrate differences in can size, sugar and caffeine; the figures do not apply to every drink a brand makes.
Red Bull
Original 250ml provides a smaller-can point of comparison, while sugar-free products are separate variants.
- Red Bull states 80mg caffeine and 27g sugars per Original 250ml can.
- Original is not sugar-free. The ASDA listing for the 250ml drink carries a high-caffeine warning.
Monster
Original Green 500ml is a larger standard-can comparison; zero-sugar Ultra drinks are distinct products.
- Monster UK lists 160mg caffeine per Original Green 500ml can.
- Monster UK also lists 55g sugar for that Original Green can; do not apply those figures to Ultra variants.
CELSIUS
Sparkling Raspberry Peach 355ml illustrates why a zero-sugar choice still needs a full-can caffeine check.
- Sainsbury's lists this Raspberry Peach variant as zero sugar.
- The same listing states 200mg caffeine per 355ml can and says it is not recommended for children, pregnant or breastfeeding women, or people sensitive to caffeine.
Relentless
White Citrus is another carbonated energy-drink formulation to assess by its own label rather than by figures for the other brands.
- Relentless describes White Citrus as a carbonated citrus-flavour drink containing caffeine, sugar and sweetener.
- Check the can's caffeine and sugar declarations before comparing it with the specific products above.

Camping energy drink questions
How much caffeine is in one sparkling energy-drink can?
It depends on the exact drink and can size. Red Bull lists 80mg in Original 250ml, Monster UK lists 160mg in Original Green 500ml, and Sainsbury's lists 200mg in CELSIUS Raspberry Peach 355ml. Read the full-can amount and include caffeine from other food, drinks and supplements in your day's plans.
Does zero sugar mean an energy drink has little caffeine?
No. Sainsbury's lists CELSIUS Raspberry Peach as zero sugar but containing 200mg caffeine per 355ml can. Compare the sugar and caffeine declarations separately for the variant you intend to buy.
What should a pregnant camper check before choosing one?
Check the drink's caffeine warning and caffeine from all sources. NHS guidance says not to have more than 200mg caffeine a day during pregnancy and includes energy drinks among its sources; that daily amount is not additional to caffeine from coffee, tea, chocolate or supplements.
Is an under-16 energy-drink sales ban already in force throughout the UK?
The Department of Health and Social Care's July 2026 announcement does not establish a current UK-wide ban. It describes an England-only ban intended for April 2027, subject to Parliamentary approval. Check the current rules at the place of purchase and the retailer's requirements.
How should canned drinks be packed with camping food?
Pack sealed cans according to their own storage labels and plan chilled-food storage separately. Food Standards Agency camping guidance says to keep raw and ready-to-eat food apart and food requiring chilling below 5°C; it warns that a cool box is unlikely to keep food chilled for an extended trip. Bring drinking water independently of the energy drinks.
