Only thanks to sweeteners are we able to offer low-calorie and no-calorie versions of your favourite drinks. 

From Diet Coke to Coke Zero, Fanta Orange Zero, Lilt Zero, Schweppes Diet Lemonade and Powerade Zero almost all Coca-Cola brands have a low-calorie or no-calorie alternative – and they account for more than a third of the drinks we sell in Great Britain.

Otherwise, we answer your most commonly asked questions below…

Why do you use low-calorie and no-calorie sweeteners?

Low and no calorie sweeteners enable us to offer low or no calorie  and low or no sugar versions of our drinks. We want to make sure everyone has lots of delicious drink options, including people who are looking to reduce their calorie and sugar intake They also offer people with diabetes a wider choice of food and drink.

We actually also use sweeteners in drinks that do contain sugar to reduce their overall calorie content. And we often blend sweeteners to get the best results.

Which sweeteners does Coca-Cola use?

The most commonly used sweeteners we use are aspartame, acesulfame-K, saccharin and stevia leaf extract (steviol glycosides).

For instance, in Diet Coke, Coke Zero, Lilt Zero and Sprite Zero, we use a blend of acesulfame-K and aspartame, while in Schweppes Slimline Canada Dry Ginger Ale and Schweppes Diet Lemonade we use aspartame and saccharin.

Stevia is extracted from the leaf of the stevia plant, and we use it in Coca-Cola Life, Sprite and glacéau vitaminwater.

How do I know if a product contains sweeteners?

We list all of the ingredients we use on our packaging and online – including sweeteners. By law, food and drink containing sweeteners must carry the words ‘with sweetener’ on the label.

Are sweeteners safe for everyone?

Sweeteners have been used all over the world for more than a century – in soft drinks, sugar-free chewing gum, desserts, medicines and yoghurts. Every sweetener we use is regularly and rigorously scientifically tested and is regarded as safe by the European Food Safety Authority (EFSA). 

 The only exception are people born with the rare genetic condition, phenylketonuria (PKU) who must avoid aspartame as they are unable to metabolise phenylalanine (see below).

Can sweeteners help me manage my weight?

When combined with an active, healthy lifestyle, sweeteners may help with weight control – but they don’t in themselves lead to weight loss. A negative energy balance (burning more calories than you take in) can aid weight loss. 

Take a look at our Work It Out calculator for suggestions on how to balance ‘energy in’ (what you eat and drink) with ‘energy out’ (the exercise you do) to help maintain a healthy weight.

Can sweeteners affect teeth?

Sweeteners do not promote tooth decay.  Poor dental hygiene habits are the main cause of tooth decay and enamel erosion. Any food or drink containing sugars and starches (fermentable carbohydrates) can contribute to tooth decay, and acidic foods and drinks can be a contributing factor to enamel erosion. Sparkling drinks are no exception. But that’s only if you don’t take care of your teeth. So brush your teeth, see your dentist regularly and follow his/her advice.

Find out more about looking after your teeth in our Guide to good dental health video.

Can people with diabetes consume sweeteners?

Yes. Studies have shown that low and no-calorie sweeteners can help people with type 2 diabetes manage their condition. It’s important for diabetics to manage their calorie intake – and sweeteners can help with this. If you have diabetes, always consult your GP for dietary advice.

Can people with PKU use sweeteners?

People with this rare genetic condition must avoid food and drink sweetened with aspartame, which includes Diet Coke, Coke Zero, Schweppes Slimline Bitter Lemon, Lilt Zero, Fanta and more. As they cannot metabolise phenylalanine, they need to control their intake of this amino acid. 

Our drinks with aspartame are clearly labelled to alert people to the presence of phenylalanine.
