Cola drinkers checking sugar
If you want a cola with 0g sugars on its nutrition panel, check that value rather than relying on the words “no added sugar”. Coca-Cola GB and Pepsi UK list 0g sugars for their standard Zero Sugar and MAX colas.
Who is this choice for?
Buyers avoiding caffeine
Look for an explicitly caffeine-free cola. The standard Coca-Cola Zero Sugar and Pepsi MAX ingredient lists include caffeine or caffeine flavouring, while both brands identify separate caffeine-free variants.
Shoppers buying a short-term refill
Choose a pack size that matches how much cola you expect to use. An individual bottle, a smaller can pack and a larger multipack make different quantities to take home for a top-up.
What should you check?
Read the nutrition panel first, then check the variant and ingredients before deciding how much to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar value | Read “of which sugars” per 100ml. Do not treat “no added sugars” as a substitute for the nutrition value. | I want the drink’s label to show 0g sugars, not simply say that sugar was not added. |
| Caffeine | Check for “caffeine-free” in the variant name and read the ingredients. Standard Coca-Cola Zero Sugar and Pepsi MAX list caffeine or caffeine flavouring, according to their UK brand pages. | If I avoid caffeine, I need the separately identified caffeine-free version, not the standard zero-sugar can. |
| Sweeteners | Read the ingredients and any phenylalanine warning. Coca-Cola GB and Pepsi UK list aspartame in their standard zero-sugar colas. | I want to know which sweeteners are in the particular variant I am buying, especially if I need to avoid aspartame or phenylalanine. |
| Pack size | Check the number of cans or the bottle volume, and compare it with the amount you expect to use. | A short refill may call for fewer cans; if I need more, a larger pack could be practical. |
| Acidity | Do not use a 0g sugar value to judge acidity. The NHS notes that carbonated drinks are associated with dental erosion because of their acid content, regardless of sugar. | If dental erosion is a concern for me, choosing sugar-free cola does not settle that separate issue. |
Common label mistakes
-
Reading “no added sugars” as “zero sugars”
The National Archives’ text of Regulation (EC) No 1924/2006 says a “no added sugars” claim requires that no mono- or disaccharides have been added. That claim is not a reading of the drink’s final sugar content.
If you want 0g sugars, check “of which sugars” on the nutrition panel, including its per-100ml value.
-
Assuming zero-sugar cola is caffeine-free
The standard Coca-Cola Zero Sugar and Pepsi MAX ingredient lists include caffeine or caffeine flavouring; their caffeine-free products are separate variants.
Choose a variant explicitly labelled caffeine-free and check its ingredients.
-
Skipping the sweetener warning
Coca-Cola GB and Pepsi UK list aspartame in their standard zero-sugar colas. Their product information also identifies a source of phenylalanine.
If you need to avoid either ingredient, read the warning and ingredient list on the exact pack before choosing it.
-
Assuming sugar-free fizz has no dental downside
The NHS associates carbonated drinks with dental erosion due to their acid content, whether or not they contain sugar.
Consider that separate issue when deciding how often cola fits into your routine; the sugar value does not answer it.

Pepsi
Pepsi UK identifies Pepsi MAX as its no-sugar cola and Pepsi MAX No Caffeine as a separate caffeine-free option.

Diet Coke Caffeine Free 8 × 330ml
This explicitly caffeine-free variant comes in eight 330ml cans. Diet Coke is a distinct cola variant from Coca-Cola Zero Sugar; check this pack’s nutrition panel and sweetener warning rather than assuming their ingredients are the same.

Pepsi Max Caffeine Free 24 × 330ml
The caffeine-free variant comes here as 24 cans of 330ml, a larger quantity to consider for a short top-up. Pepsi UK identifies its No Caffeine variant as zero sugar; check the exact pack’s ingredients and phenylalanine warning if relevant.
Questions about no-sugar cola
Does “no added sugar” mean a cola contains 0g sugars?
No. The National Archives’ text of Regulation (EC) No 1924/2006 sets a condition about sugars added to a product; it does not replace the nutrition value. If you want 0g sugars, read “of which sugars” per 100ml on the pack.
Which variant should I check if I avoid caffeine?
Choose a cola explicitly labelled caffeine-free and confirm its ingredients. Coca-Cola GB and Pepsi UK list caffeine or caffeine flavouring in their standard Zero Sugar and MAX products, alongside separate caffeine-free variants.
Does caffeine-free also mean sweetener-free?
No. Caffeine and sweeteners are separate ingredient checks. Read the exact variant’s ingredient list and any phenylalanine warning if you need to avoid aspartame or phenylalanine.
Does sugar-free cola avoid the dental concern associated with fizzy drinks?
No. The NHS notes that carbonated drinks are associated with dental erosion due to acid content regardless of whether they contain sugar. A 0g sugar value does not describe that separate property.
What pack size makes sense for a top-up shop?
Choose a quantity you expect to use: an eight-can pack, a 12-can pack and a 24-can pack each represent a different commitment. Check the number and size of servings before choosing a larger multipack for a short refill.
