Takeaway-night shoppers checking sugars
If you want an energy drink with your meal but are avoiding sugars, compare the nutrition panel and ingredients rather than relying on the name on the front of the can.
Who is this choice for?
Evening drinkers comparing caffeine servings
Can size matters when deciding how much caffeine to have with a meal. Red Bull specifies 80 mg in a 250 ml Sugarfree can; Monster Energy UK specifies 150 mg in a 500 ml Monster Ultra can.
Shoppers checking high-caffeine warnings
Check the warning on the exact drink before buying it for someone else. The reviewed retailer listings warn against these high-caffeine drinks for children and for pregnant or breast-feeding women.
What should you check?
Start with the sugars declaration, then compare caffeine for the can you intend to drink. A multipack count does not change the amount in each can, but it is worth checking the exact variant and can size before choosing.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars declaration | Read sugars per 100 ml on the nutrition panel and check the exact wording on the can. A no-added-sugar claim and a sugar-free claim describe different conditions. | I want to know what the drink declares about sugars, not assume that similar-sounding claims mean the same thing. |
| Caffeine per can | Compare the whole-can amount as well as any figure per 100 ml. Red Bull specifies 80 mg per 250 ml Sugarfree can; Monster Energy UK specifies 150 mg per 500 ml Monster Ultra can. | For an evening meal, the amount in the can I actually plan to drink matters more to me than the figure per 100 ml alone. |
| Ingredients and warnings | Read the sweetener ingredients and high-caffeine warning on the exact variant. A sugar-free drink can still contain caffeine and sweeteners. | I want to check what is in the drink and whether its warning makes it unsuitable for the person I am buying for. |
| Can and pack size | Confirm the volume of each can and the number of cans in the pack. For a Japan-version product, also check the label applicable to the can being sold. | A smaller single can may suit the serving I have in mind, while a larger can or multipack is a different purchase decision. |
Common buying mistakes
-
Assuming sugar-free means caffeine-free
Red Bull specifies 80 mg caffeine in a 250 ml Sugarfree can, while Monster Energy UK lists 150 mg in a 500 ml Monster Ultra can. Choosing by the sugar claim alone misses that difference in whole-can servings.
Decide how much of the can you intend to drink and check its caffeine amount before choosing a size or multipack.
-
Treating no added sugar and sugar-free as interchangeable
The two claims describe different things; a no-added-sugar label is not, by itself, a declaration of zero sugars.
Read the exact claim, the sugars line on the nutrition panel and the ingredient list, including any sweeteners.
Brand and retailer references
These references describe particular drinks or listings, not every product made or stocked under each name.
Red Bull
Red Bull specifies 80 mg caffeine in a 250 ml Sugarfree can, making its stated whole-can serving straightforward to compare with a larger format.
- A 250 ml Sugarfree can provides a defined smaller serving.
- Sugarfree is still caffeinated. A separate Sainsbury's listing for Sugar Free Blue Edition Juneberry names sucralose and acesulfame K and carries a high-caffeine warning; check the ingredients and warning on the variant you buy.
Monster
Monster Energy UK describes Monster Ultra as a citrus-flavoured, zero-sugar 500 ml drink with 150 mg caffeine per can.
- The stated 500 ml format suits shoppers specifically looking for a larger can.
- Its stated whole-can caffeine amount is higher than the 80 mg Red Bull specifies for one 250 ml Sugarfree can. Check the label of the exact Monster variant and pack.
Tesco
Tesco Groceries has listed Red Bull Sugar Free and Monster Energy Ultra multipacks in its UK energy-drinks category.
- Its category listing provides another place to compare the named product families and pack formats.
- A category listing does not establish the ingredients of a Tesco own-label drink or guarantee that a particular pack is available for your delivery area.

No image available
Monster Ultra Zero Sugar 4 × 500 ml
This four-pack is another 500 ml-can option. Caffeine figures associated with this listing conflict, so check the amount printed on the exact can before comparing it with a smaller serving; also read its high-caffeine warning.

Monster Japan Version Ultra 355 ml
The 355 ml can sits between the smaller and larger formats shown here. Because it is identified as a Japan-version product, check the label applicable to the can being sold, including sugars, ingredients, whole-can caffeine and warnings.
Questions about sugar and caffeine
Does no added sugar mean the same thing as sugar-free?
No. The phrases describe different conditions, so do not assume that a no-added-sugar claim means the drink declares zero sugars. Check the exact wording, the sugars value on the nutrition panel and the ingredients.
Are sugar-free energy drinks caffeine-free?
No. Red Bull specifies 80 mg caffeine in a 250 ml Sugarfree can, and Monster Energy UK specifies 150 mg in a 500 ml Monster Ultra can. Compare the amount for the can you intend to drink.
Should I buy one of these drinks for a child?
The reviewed retailer listings warn that the named high-caffeine Red Bull and Monster drinks are not recommended for children. Choose a non-caffeinated drink instead and check the warning on any alternative.
What if I am pregnant or breast-feeding?
The reviewed high-caffeine product warnings say these drinks are not recommended for pregnant or breast-feeding women. A sugar-free label does not remove the caffeine; check the warning on the exact drink and choose a non-caffeinated alternative.
What matters when choosing a multipack for takeaway nights?
Check the variant, number of cans, volume per can, sugars declaration, ingredients and caffeine per can. Confirm the current product details and delivery eligibility before ordering rather than assuming that similarly named multipacks contain the same drink.
