Choose a multipack by the can you would take in the morning, not just the number of cans: a 250ml Red Bull Original has 80mg caffeine, while Monster says a 500ml Ultra has 150mg and no sugar. An energy drink is an optional drink alongside breakfast, not a substitute for food; check the sugar, caffeine and serving size of the exact variant before buying.
A 250ml can takes up less space than a 500ml can. Red Bull states that its 250ml Original contains 80mg caffeine; Monster states that a 500ml Ultra contains 150mg. Compare the exact variants rather than assuming can size alone determines caffeine content.
Monster describes its 500ml Ultra as containing no sugar, but also states that it contains 150mg caffeine. Check both figures when choosing a can for the morning.
A multipack can reduce how often you need to restock, but pack count does not change what is in each can. Compare the can size and label of the variant you intend to drink.
Start with the portion you would actually take, then read its caffeine and sugar information before deciding how many cans to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Check the figure for the exact variant and can size. Red Bull states 80mg per 250ml Original can; Monster states 150mg per 500ml Ultra can. Count caffeine from other drinks and foods too. | I want to know how much caffeine one morning can adds to everything else I consume that day. |
| Sugar | Compare sugar per can, not just the name of the range. Red Bull states 27g sugars per 250ml Original can; Monster describes its 500ml Ultra as containing no sugar. | For a no-sugar option, I still need to check the caffeine amount. |
| Can size | Compare 250ml, 355ml and 500ml cans as separate portions. Check whether you want to carry and drink the whole can at breakfast time. | A smaller can may fit my commute better; on another morning, I might prefer a larger serving. |
| Breakfast food | Plan food separately from the drink. The NHS Eatwell Guide describes a balanced diet through food groups including starchy foods, fruit and vegetables, and protein foods. | If I am grabbing breakfast on the way out, a can alone is not the meal I meant to prepare. |
| Pack format | Check the can count, volume per can and packaging. Sainsbury's lists Lucozade Energy Original as 12 × 330ml cans; other Lucozade Energy multipacks include bottles. | I want enough cans for my routine, but I need to make sure the pack contains cans of the size I want. |
More cans in a pack do not mean a smaller serving. A 500ml can and a 250ml can make different demands on the space in your bag and on how much you intend to drink at once.
Check both the number of cans and the volume and caffeine content of each can.
Monster says its 500ml Ultra contains no sugar and 150mg caffeine. The sugar statement tells you nothing about the caffeine amount.
Read the caffeine figure separately and include other caffeine sources when considering your daily intake.
An energy drink does not replace the food groups described in the NHS Eatwell Guide.
Arrange food you can take with you, then decide separately whether you want a caffeinated drink.
Retailer requirements can affect an order. Sainsbury's says it does not sell high-caffeine energy drinks to under-16s and may request proof of age on delivery for products labelled as not recommended for children.
