Yes, Sunkist Zero Sugar is Caffeinated
It is a common misconception that all orange sodas are free of caffeine, but the Sunkist brand is a notable exception. A 12 fl oz can of Sunkist Zero Sugar orange soda contains 19 mg of caffeine. This is the exact same amount of caffeine found in its full-sugar counterpart. This information is clearly listed on the product's nutrition label and ingredient list, so you can always check before consuming.
The Reason for Caffeine in Sunkist
While the exact historical reasons for Sunkist's choice to include caffeine are not widely documented, it likely has to do with market strategy and flavor enhancement. Some theories suggest that in the past, including caffeine was a way to compete with colas and other popular caffeinated soft drinks. Caffeine is also known to enhance the natural flavors in some beverages, which may be part of the reason for its inclusion. Whatever the original reason, the caffeinated formula has remained consistent for decades.
Other Sunkist Varieties are Caffeine-Free
For those seeking a caffeine-free option from the Sunkist brand, it's important to know that the orange flavor is the exception. The following popular Sunkist soda varieties are caffeine-free:
- Grape
- Strawberry
- Cherry Limeade
- Pineapple
- Peach
- Fruit Punch
- Berry Lemonade
- Mango Orange
Comparison Table: Sunkist Zero Sugar vs. Other Sodas
To put Sunkist Zero Sugar's caffeine content into perspective, here is a comparison with other common zero-sugar and regular sodas per 12 fl oz serving, based on information from the Center for Science in the Public Interest:
| Soda Brand | Caffeine (mg per 12 fl oz) | Notes | 
|---|---|---|
| Sunkist Zero Sugar | 19 | Notably caffeinated for an orange soda | 
| Fanta Orange Zero | 0 | Most other orange sodas are caffeine-free | 
| Coca-Cola Zero Sugar | 34 | Typical caffeine content for zero-sugar colas |

Ingredients in Sunkist Zero Sugar
Beyond caffeine, Sunkist Zero Sugar uses artificial sweeteners and coloring to achieve its flavor and zero-calorie status. Key ingredients listed on product packaging include:
- Carbonated Water
- Citric Acid
- Sodium Benzoate (Preservative)
- Aspartame and Acesulfame Potassium (Artificial Sweeteners)
- Natural Flavors
- Yellow 6 and Red 40 (Artificial Coloring)
The use of artificial sweeteners and food dyes can be a point of consideration for some consumers. The Environmental Working Group (EWG), for example, has flagged some of these ingredients in Sunkist Zero Sugar for their potential health implications, recommending moderation.
The Change from 'Diet' to 'Zero Sugar'
The current Sunkist Zero Sugar replaced the older Diet Sunkist product, and the transition involved a change in the formula. The original Diet Sunkist orange soda reportedly had a higher caffeine content of 41 mg per 12 fl oz, which was then lowered to 19 mg with the rebranding to Sunkist Zero Sugar. This shows that the caffeine level has been intentionally adjusted over time, not accidentally included.
Conclusion
To put it simply, yes, Sunkist Zero Sugar is caffeinated, with 19 mg per 12 fl oz serving. While this might go against the general assumption that orange sodas are caffeine-free, the product labeling clearly states its ingredients, including caffeine. For consumers who need to manage their caffeine intake, it is crucial to check the ingredient list of any soda, especially fruit-flavored ones, as Sunkist is not the only exception to the rule. Always read the label to ensure you are selecting the right beverage for your dietary needs.
