Night-shift workers sleeping soon after work
If you want a fizzy drink after your shift, caffeine is worth checking before you buy. NHS Borders advises avoiding caffeine-containing drinks close to bed because they can disrupt sleep.
Who is choosing a drink?
Glass-bottle cola drinkers reducing sugar
Your Coca-Cola UK lists its Zero Sugar glass bottles as containing zero sugar and calories, but their ingredients still include caffeine flavouring.
Shoppers looking for caffeine-free orange fizz
Your Coca-Cola UK describes Fanta Orange glass bottles as caffeine free. Its nutrition information lists 4.5g sugars per 100ml, so check the serving size as well as the flavour.
What should you check?
Start with when you expect to sleep, then compare the drink's sugar information and the bottle size you would use for a snack break.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine | Check the current ingredients for caffeine and look for an explicit caffeine-free statement if you need one. Your Coca-Cola UK lists caffeine flavouring in both researched Coca-Cola glass-bottle variants; it describes Fanta Orange as caffeine free. | If I plan to sleep soon after work, I want to know whether my drink contains caffeine. NHS Borders advises avoiding caffeine-containing drinks close to bed. |
| Sugar | Compare sugars per 100ml and the volume you expect to drink. Your Coca-Cola UK lists Fanta Orange at 4.5g sugars per 100ml and its Sprite Zero Sugar and Coca-Cola Zero Sugar glass bottles at 0g sugars per 330ml. | I'd check the nutrition information rather than assume that an orange flavour, a caffeine-free statement or a cola name tells me how much sugar is in the bottle. |
| Bottle size | Check the volume of each bottle and how many are in the pack. Your Coca-Cola UK lists individual 330ml bottles in its 24-bottle glass packs; Tesco lists Coca-Cola Original Taste in four 250ml glass bottles. | For one snack break, I want a bottle size that suits the amount I intend to drink, with room to store the rest of the pack. |
Common buying mistakes
-
Assuming zero sugar means caffeine free
Your Coca-Cola UK lists caffeine flavouring in Coca-Cola Zero Sugar glass bottles. Removing sugar does not establish that a cola is free of caffeine, which matters if you plan to sleep soon after a shift.
Check the ingredients for caffeine separately from the sugar declaration. NHS Borders advises avoiding caffeine-containing drinks close to bed.
-
Assuming caffeine-free orange fizz has no sugar
Your Coca-Cola UK describes Fanta Orange glass bottles as caffeine free, but lists 4.5g sugars per 100ml.
Read the nutrition table alongside the bottle volume if the amount of sugar in your serving matters to you.
-
Comparing packs without checking bottle size
A four-pack of 250ml bottles and a 24-pack of 330ml bottles offer different serving sizes and quantities. The pack count alone does not tell you how much is in each bottle.
Check the bottle volume, pack count and the space available to store the bottles.
A 24-bottle pack also needs space for bottles you will use later.

Questions about choosing and using these drinks
