For a cinema snack run, compare the caffeine in the whole can and the sugar declaration before choosing by flavour or size. Red Bull UK lists 80 mg caffeine in a 250 ml Original or Sugarfree can, while Monster Energy UK lists 160 mg in a 500 ml Zero-Sugar can; the smaller serving and the zero-sugar option meet different priorities, and those figures should not be assumed to apply to other varieties.
If the screening is late, the caffeine in the complete can matters more to your comparison than can size alone. Red Bull UK states 80 mg for its 250 ml Original can; Monster Energy UK states 160 mg for its 500 ml Zero-Sugar can. Caffeine from other drinks that day matters too.
Confectionery or other sweet snacks may make the drink’s sugar declaration a deciding factor. Monster Energy UK lists 0 g sugar in a 500 ml Zero-Sugar can and 55 g in a 500 ml Original Green can. Check the variety you intend to drink rather than applying either figure across the range.
Relentless describes White Citrus as a carbonated citrus-flavour drink with sugar and sweetener. Lucozade describes its Energy range as sparkling and containing glucose. Those descriptions help narrow the flavour or formulation, but the exact container is still the place to check caffeine and nutrition.
Start with the amount you would drink during the film, then compare the exact variety’s caffeine, sugar and flavour information.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Read the amount for the complete container, not just per 100 ml. Red Bull UK states 80 mg per 250 ml Original can; Monster Energy UK states 160 mg per 500 ml Zero-Sugar can. Include other caffeine consumed that day. | For a late film, I want to know how much caffeine I would have if I finished the can. |
| Sugar | Check sugars on the nutrition panel for the exact variety and serving. Monster Energy UK lists 0 g per 500 ml Zero-Sugar can and 55 g per 500 ml Original Green can; Lucozade describes its Energy range as containing glucose. | If I am buying sweet snacks too, the drink’s declared sugar may change which formulation I choose. |
| Size and flavour | Compare the complete 250 ml or 500 ml serving and read the particular flavour description. Relentless describes White Citrus as carbonated citrus flavour with sugar and sweetener; Lucozade describes its Energy range as sparkling. | Would I rather carry a smaller can into the cinema, or have a larger drink? Flavour matters to me, but it does not tell me the caffeine or sugar content. |
| Warnings and suitability | Read the warning on the exact product, particularly when buying for a child or someone sensitive to caffeine. The NHS advises no more than 200 mg caffeine a day during pregnancy, counting all sources. | I need to check who will drink it, rather than assuming a fizzy drink suits everyone in the group. |
The amount of caffeine in a whole serving can differ: Red Bull UK lists 80 mg in a 250 ml Original can, while Monster Energy UK lists 160 mg in a 500 ml Zero-Sugar can.

The Department of Health and Social Care and Department for Education announced that England will ban sales of high-caffeine energy drinks to under-16s from April 2027. That announcement does not establish the same rule for every UK nation or an earlier purchase date.
For an under-16 purchase, check the rules where and when it takes place, as well as the retailer’s age-verification requirements.
Relentless White Citrus carries a manufacturer warning for children, people sensitive to caffeine, and pregnant or nursing women. The NHS advises no more than 200 mg caffeine a day during pregnancy, including caffeine from energy drinks and other sources.
