People combining caffeine sources
If you also have coffee, an energy drink or a caffeinated pre-workout product, distinguish cola containing caffeine from an explicitly caffeine-free variant before combining them.
Who is choosing?
The useful distinction is whether you are choosing a fizzy drink, managing caffeine or looking for food before training.
People choosing cola without sugar
A zero-sugar cola can meet a preference for cola flavour without sugar. It is still a drink choice, not a replacement for a planned pre-workout snack.
People who prefer regular cola
Compare the sugar information per 100 ml and for the pack you intend to drink, rather than assuming regular cola provides everything you want from a snack.
What should you check?
Decide whether you want a drink or a snack, then compare the sugar, caffeine and ingredients of the cola you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100 ml and the volume you intend to drink. Coca-Cola GB lists 10.6 g sugars per 100 ml for Original Taste; Pepsi UK lists 0 g for Pepsi Max and 4.5 g for regular Pepsi. | I want to know how much sugar comes with the cola I choose, or I would rather choose a zero-sugar variant. |
| Caffeine | Check whether the exact variant contains caffeine or is explicitly caffeine-free. If combining drinks or supplements, check the labelled caffeine amounts across them. | Coffee, an energy drink or a pre-workout product may already be part of my routine, so I do not want to add caffeine without checking. |
| Drink or snack | Decide whether cola is simply the drink you want or whether you need food and fluids before training. UK Sports Institute guidance favours a varied, food-first approach to training nutrition. | I am looking for something to have before exercise and do not want to mistake a can of cola for a complete snack. |
| Ingredients | Read the ingredients on the exact pack, particularly when choosing a sweetened zero-sugar variant or checking for a caffeine-free formulation. | The ingredient list matters to my choice, not just whether the front of the pack says zero sugar. |
Common buying mistakes
-
Treating zero-sugar cola as a snack
Zero-sugar cola may provide the flavour you want, but it does not replace food before a session that calls for a planned snack. UK Sports Institute guidance takes a food-first approach to training nutrition.
Decide separately what you want to drink and whether you need to plan food before training.
-
Adding cola to other caffeine without checking
Pepsi UK lists caffeine in Pepsi Max, and Coca-Cola GB lists caffeine flavouring in Original Taste. Either can add to caffeine from other products you use.
Check the caffeine amount on each relevant pack before combining products; choose an explicitly caffeine-free cola if you do not want to add caffeine.
-
Assuming zero sugar means caffeine-free
Pepsi Max contains caffeine despite listing 0 g sugars per 100 ml. Pepsi Max No Caffeine and Coca-Cola Zero Sugar Caffeine Free are distinct caffeine-free variants, according to their manufacturers.
Check the full variant name and ingredients when avoiding caffeine is the reason for your choice.
-
Applying school-food guidance to personal shopping
Department for Education school-food guidance concerns food and drink provided in schools in England. Choosing a cola for yourself before a workout is a different setting.
If you are buying for a school, check the rules for that nation and institution rather than relying on personal-shopping advice.
Brand and retailer references
Variant names matter more than the brand alone: regular, zero-sugar and caffeine-free colas can have different sugar and caffeine information.

Frequently asked questions
Can cola be my pre-workout snack?
Treat cola as an optional drink, not as a complete pre-workout snack. If you are planning food around training, UK Sports Institute guidance favours a varied, food-first approach.
Should I choose regular or zero-sugar cola before training?
Choose according to whether you want the sugar in regular cola, not because either type is a complete fuelling plan. Coca-Cola GB lists 10.6 g sugars per 100 ml for Original Taste, while Pepsi UK lists 0 g for Pepsi Max; check caffeine separately for the variant you choose.
Can I combine caffeinated cola with a pre-workout product?
Check the labelled caffeine amounts of both products and any other caffeine you plan to have before combining them. If you cannot establish the amounts or do not want to add caffeine, choose an explicitly caffeine-free cola instead.
How can I choose cola without caffeine?
Look for an explicitly caffeine-free variant rather than assuming zero sugar means caffeine-free. Coca-Cola GB describes Coca-Cola Zero Sugar Caffeine Free as caffeine-free, and Pepsi UK describes Pepsi Max No Caffeine the same way.
