Guests choosing a sugar-free energy drink
Compare caffeine per can before choosing a size. Red Bull UK states 80mg in a 250ml Sugarfree can; Monster Energy UK lists 160mg in its 500ml Absolutely Zero can.
Who are the drinks for?
Hosts offering more than one drinks option
Keep zero-sugar energy drinks distinct from zero-sugar soft drinks, so guests can check the caffeine information for the drink they choose.
Guests for whom caffeine needs particular attention
A sugar-free label does not remove caffeine. GOV.UK requires a warning on drinks containing more than 150mg/l caffeine stating that they are not suitable for children, pregnant women or people sensitive to caffeine.
What should you check before buying?
Start with the type of drink guests want, then read the exact pack for sugar, can size and caffeine information.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar content | Check the nutrition information for the exact flavour and pack. Red Bull UK describes Sugarfree as containing no sugars; Monster Energy UK lists 0g sugar for its 500ml Absolutely Zero can. | I want an energy-drink option without the sugars in a regular formulation. |
| Caffeine per can | Compare the amount in the entire container, not just per 100ml. Red Bull UK states 80mg per 250ml Sugarfree can; Monster Energy UK lists 160mg per 500ml Absolutely Zero can. | A smaller can may suit the amount of caffeine I want at this party, particularly if I have had other caffeinated food or drinks. |
| Guest warnings | Keep the packaging available to read. GOV.UK requires a warning for drinks containing more than 150mg/l caffeine, including that they are not suitable for children, pregnant women or people sensitive to caffeine. | I need drinks choices that do not assume every guest wants, or can choose, a caffeinated energy drink. |
| Soft-drink option | Lucozade describes its Zero range as zero sugar and its Orange Zero drink as zero calories. Check the individual bottle or can for caffeine information if that affects the choice. | For an evening party, I may want a zero-sugar soft drink instead of an energy drink. |
Common buying mistakes
-
Reading “zero sugar” as “no caffeine”
Red Bull UK states that Sugarfree contains 80mg caffeine per 250ml can, while Monster Energy UK lists 160mg per 500ml Absolutely Zero can.
Read the caffeine amount for the whole can and account for other caffeinated food and drinks.
-
Comparing cans without checking their size
The stated caffeine amounts above refer to different serving sizes: 250ml and 500ml. A per-can comparison matters when guests are likely to drink the entire container.
Check both can size and caffeine per can before choosing which packs to serve.
-
Making energy drinks the only sugar-free choice
A sugar-free energy drink still needs its caffeine content and warnings considered. GOV.UK requires a suitability warning on drinks containing more than 150mg/l caffeine.
Offer a separately identified soft-drink option and leave its packaging available for guests to check.
-
Assuming every drink from a brand is sugar-free
The ingredients listed by Relentless for its Cherry drink include sucrose and glucose.
Check the nutrition panel and ingredients for the exact flavour and formulation, especially when buying a multipack.
Relevant brand ranges
Red Bull
Red Bull Sugarfree is a 250ml sugar-free energy-drink option.
- Red Bull UK states that one 250ml Sugarfree can contains 80mg caffeine and uses sucralose and acesulfame K in place of sugars.
- Sugarfree still contains caffeine; check the exact product rather than treating “sugar-free” as a caffeine description.
Monster Energy
The brand lists a 500ml Absolutely Zero energy drink alongside its other formulations.
- Monster Energy UK lists 0g sugar and 160mg caffeine for its 500ml Absolutely Zero can.
- That stated caffeine amount is for the full 500ml can; check the exact formulation when comparing another Monster product.
Lucozade
Lucozade Zero provides a soft-drink route rather than an energy-drink selection.
- Lucozade describes the Zero range as zero sugar and Orange Zero as zero calories.
- Check the exact drink’s label if its caffeine content affects your choice.
Relentless
Check individual Relentless formulations rather than assuming the brand name identifies a sugar-free drink.
- Relentless publishes an ingredients list for its Cherry drink, allowing that formulation to be checked.
- The Cherry ingredients include sucrose and glucose, so that product does not meet a zero-sugar preference.

Frequently asked questions
Does zero sugar mean an energy drink has no caffeine?
No. Red Bull UK states that a 250ml Sugarfree can contains 80mg caffeine, and Monster Energy UK lists 160mg in a 500ml Absolutely Zero can. Compare the amount stated for the exact drink and can size.
Should caffeine from other drinks count when planning party drinks?
Yes. The European Food Safety Authority’s 2015 opinion assesses daily caffeine intake from all sources, not energy drinks alone. Its figures for general healthy adults are not a target or a recommendation for every guest.
What if a guest is pregnant?
A zero-sugar energy drink still contributes caffeine. The NHS advises no more than 200mg caffeine a day during pregnancy and identifies energy drinks among the sources to count; guests can use the exact pack information when checking what a drink contains.
What warning should I look for on a high-caffeine drink?
GOV.UK states that drinks containing more than 150mg/l caffeine must carry a warning that they are not suitable for children, pregnant women and people sensitive to caffeine. Read the warning on the exact pack being served.
