Shoppers buying multipacks
If you are stocking up for home, study or work, check the number of cans and their volume before comparing packs. A larger pack only makes sense if you expect to use it and can store it.
Who these choices suit
Shoppers checking sugar content
Choose by the exact variant, not the brand alone. Monster states that its 500ml Zero Sugar drink contains 0g sugar, while its Original Green 500ml drink contains 55g; the figures are variant-specific and may differ by region.
Adults comparing caffeine portions
Check caffeine per can as well as can size, particularly if you also consume caffeine from other sources. Red Bull states 80mg for its original 250ml can; Monster states 160mg for its 500ml Zero Sugar drink, with regional variation possible for the latter.
What to check before choosing
Start with the amount you will use, then compare the sugar and caffeine information on the exact pack. If an age check could affect the purchase, check the retailer's rules before ordering.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Compare can volume and the number of cans. For a bottle or multipack, consider whether you can store and use the full amount. | I'm stocking up, but I want a pack size that fits what I will actually use. |
| Sugar choice | Read the nutrition panel for the exact flavour and variant. Check grams of sugars against the stated serving size; do not treat 'no added sugar' as 'zero sugar'. | A zero-sugar version matters to me, so I need to distinguish it from a regular drink in the same range. |
| Caffeine portion | Find the stated milligrams of caffeine per can or serving. Consider the number of servings and caffeine from other drinks or foods. | I'd rather know the caffeine amount in the portion I plan to drink than judge it by can size alone. |
| Age checks | Read the warning on the exact drink and the chosen retailer's current age-verification rules, including rules for delivery. | I'm ordering for someone under 16, or an age check could affect who can receive the order. |
Mistakes to avoid
-
Assuming every drink from a brand has the same sugar content
Monster's stated figures differ between its 500ml Zero Sugar and Original Green drinks: 0g and 55g sugar respectively. A brand name alone cannot identify the formulation.
Check the nutrition panel for the exact variant, flavour and serving size you intend to buy.
-
Using can size as a substitute for a caffeine figure
Red Bull states 80mg caffeine in its original 250ml can, while Monster states 160mg in its 500ml Zero Sugar drink. Those are figures for named products, not every drink in either range.
Read the caffeine statement on your chosen pack and account for caffeine from other sources.

Assuming one under-16 rule applies at every UK checkout
Sainsbury's says it does not sell high-caffeine energy drinks to under-16s. Separately, the UK Government announced an intended England sales ban from April 2027, subject to Parliamentary approval, for drinks other than tea or coffee containing more than 150mg caffeine per litre.
Check the retailer's current policy and the product warning. Do not treat the proposed England rule as a rule already in force across the UK.
Brands and retailers to distinguish
These references describe particular drinks, ranges or retailer rules; they do not establish that every variant has the same formulation or that a product is available on Joybuy.
Lucozade
Lucozade describes its Energy range as sparkling and containing glucose.
- The range includes formats for shoppers considering bottles or multipacks.
- Check the exact pack before assuming a particular sugar or caffeine amount.
Relentless
Relentless Origin appears in a 4 × 500ml format in Sainsbury's listings.
- That format gives a defined large-can multipack to compare with smaller cans.
- Relentless describes White Citrus as carbonated and caffeinated, but its formulation and warnings should not be assumed to be identical to Origin's.
Monster
Monster provides different sugar formulations within its energy-drink range.
- Monster states 0g sugar and 160mg caffeine for its 500ml Zero Sugar drink; it says figures may vary by region.
- Monster states 55g sugar for Original Green 500ml. Do not transfer either drink's figures to an Ultra variant without checking it.
Red Bull
The original 250ml can provides a stated smaller-can caffeine portion.
- Red Bull states 80mg caffeine for its original 250ml drink.
- The same original can is stated to contain 27g sugars; other variants need their own label check.
Tesco
Tesco's energy-drink category includes different can sizes, multipacks and sugar formulations.
- Its listings provide pack formats that can be compared side by side.
- Check the exact listed variant and pack rather than treating similar names as interchangeable.
Sainsbury's
Sainsbury's lists branded and own-label energy drinks and publishes an age policy for high-caffeine drinks.
- Its range provides different pack formats to examine.
- Sainsbury's says it does not sell high-caffeine energy drinks to under-16s and applies age verification to products stating they are not recommended for children.
Joybuy product options
These sparkling energy-drink options include stock-up packs, a named zero-sugar variant and smaller 250ml cans. Compare each exact pack's label with the amount you intend to use; the pack format alone does not settle a budget decision.

Rockstar Blueberry & Pomegranate 12 × 500ml
The 12-can pack is an option to examine if you are stocking up. Each named can is 500ml; check the exact pack for its sugar, caffeine and warnings before choosing a serving.

Monster Energy Green Zero Sugar × 12 cans
This named zero-sugar variant is a 12-can option for shoppers seeking a multipack. Check its own label for can volume and caffeine rather than applying figures from another Monster variant.

PerfectTed Energy Juicy Peach 4 × 250ml
Four 250ml cans offer a smaller stated can size than the 500ml pack above. Check this exact drink's caffeine statement and nutrition panel; a smaller can does not establish its sugar or caffeine content.
No image available
Lucozade Energy Orange 24 × 330ml
This 24-can pack is an option if you want to stock up on Lucozade Energy Orange. Lucozade describes its Energy range as sparkling and containing glucose; check this exact pack for its nutrition information and caffeine per can.
Questions about choosing and use
How do I compare a larger multipack with smaller cans?
Check the number of cans and volume per can, then compare the exact drinks' sugar and caffeine statements. Pack size alone does not tell you whether the servings suit you, and figures from one variant should not be applied to another.
Should I choose a sparkling energy drink to replace fluids after exercise?
Do not assume that carbonation or caffeine makes a drink better for replacing lost fluids. NHS guidance identifies water as the way to replace fluids lost through sweating; check an energy drink's label for its other ingredients when deciding whether you want it.
Can someone under 16 buy a high-caffeine energy drink?
Sainsbury's says it does not sell high-caffeine energy drinks to under-16s and applies age verification to products marked as not recommended for children. Separately, the UK Government announced an intended England sales ban from April 2027, subject to Parliamentary approval, for drinks other than tea or coffee containing more than 150mg caffeine per litre. Check the chosen retailer's current policy rather than assuming the announced rule already applies throughout the UK.
