What Is Sunkist Zero?
Sunkist Zero is a diet soft drink created for those who want the bright, sweet taste of orange soda without the added sugar. It’s produced by Keurig Dr Pepper and has become a popular alternative for soda lovers who are watching their calorie intake.
Key features of Sunkist Zero include:
- Sugar‑Free Formula – Sweetened with artificial sweeteners instead of sugar.
- Citrus Flavor – Delivers the same bold orange taste as regular Sunkist.
- Caffeine Content – Contains caffeine, unlike most orange sodas.
- Low Calorie – Virtually zero calories per serving.
- Wide Availability – Sold in cans, bottles, and multi‑packs.
Sunkist Zero is designed to appeal to people who want a refreshing soda with fewer calories but still enjoy the mild boost that caffeine provides.
Ingredients in Sunkist Zero
The ingredients in Sunkist Zero are carefully chosen to replicate the flavor of the original soda while keeping it sugar‑free.
Typical ingredients include:
- Carbonated Water – Provides the fizzy base.
- Citric Acid – Adds tartness and enhances flavor.
- Aspartame & Acesulfame Potassium – Artificial sweeteners that replace sugar.
- Natural Flavors – Contribute to the signature orange taste.
- Caffeine – Provides a mild stimulant effect.
- Preservatives (e.g., Sodium Benzoate) – Maintain freshness and shelf life.
These ingredients work together to deliver a sweet, citrusy soda experience without the calories of regular Sunkist. The inclusion of caffeine makes it unique compared to other orange sodas.

Caffeine in Sunkist Zero by Serving Size (12 oz, 16.9 oz, 20 oz & More)
Sunkist Zero contains a modest amount of caffeine, making it a low‑caffeine beverage compared to coffee or energy drinks.
