Decoding Artificial Sweeteners in the Pepsi Product Line
For consumers monitoring their sugar intake, the use of artificial sweeteners in diet and zero-sugar beverages is a key point of interest. While many assume all sugar-free Pepsis are the same, the reality is more complex. PepsiCo formulates different products with distinct combinations of sweeteners to achieve specific taste profiles. The answer to "What is the artificial sugar in Pepsi?" depends heavily on which product you are examining.
The Sweetener in Diet Pepsi
Historically, Diet Pepsi in the US has been primarily sweetened with aspartame. A brief change in 2015 to a sucralose and acesulfame potassium blend in the US was reversed in 2018 due to negative consumer feedback on taste, returning the US version to its aspartame formula. It's worth noting that international formulations, such as in the UK, may differ and include acesulfame potassium alongside aspartame.
The Sweeteners in Pepsi Zero Sugar
Pepsi Zero Sugar, known in some areas as Pepsi Max, is formulated with a blend of aspartame and acesulfame potassium (Ace-K). This combination is designed to provide a bolder flavor profile that closely resembles regular Pepsi, appealing to consumers who want a zero-calorie drink without a perceived compromise on taste.
Comparing the Sweetener Blends
Blending sweeteners helps to mask potential aftertastes and create a more balanced flavor profile. Acesulfame potassium is often paired with other sweeteners because it helps to enhance and maintain sweetness over time.
| Feature | Diet Pepsi (US) | Pepsi Zero Sugar (US) |
|---|---|---|
| Primary Sweeteners | Aspartame | Aspartame & Acesulfame Potassium (Ace-K) |
| Taste Profile | Lighter, smoother. | Bolder, more intense, closer to original Pepsi. |
| Aftertaste Perception | Some may detect an aspartame aftertaste. | Blend aims to minimize aftertaste. |
| Marketing Focus | Traditionally focused on weight management. | Targets those wanting zero sugar without sacrificing flavor. |
| Formulation Change History | Reverted to aspartame after a brief sucralose switch. | Blend designed for robust flavor from introduction. |
The Use of Sucralose
While sucralose (Splenda) is not the main sweetener in current US Diet Pepsi or Pepsi Zero Sugar, it has been used in past formulations and appears in some international and specific PepsiCo products. Sucralose is considerably sweeter than sugar and is valued for its clean, sugar-like taste and heat stability. For example, Pepsi Original in the UK contains sucralose and acesulfame K alongside sugar.
A Deeper Dive into the Sweeteners
- Aspartame: A low-calorie sweetener about 200 times sweeter than sugar, composed of aspartic acid and phenylalanine. It is widely used and considered safe by regulatory bodies like the FDA. Individuals with PKU must avoid it due to its phenylalanine content.
- Acesulfame Potassium (Ace-K): A calorie-free sweetener approximately 200 times sweeter than sugar, frequently used in combination with others to enhance flavor and create a sugar-like profile.
- Sucralose: A non-nutritive sweetener around 600 times sweeter than sugar, known for its clean taste. While not primary in current US Diet Pepsi, its use elsewhere highlights its role in PepsiCo's sweetener portfolio.
The "Diet" vs. "Zero Sugar" Naming Convention
The distinction between "Diet" and "Zero Sugar" primarily reflects marketing strategies rather than fundamental health differences, although sweetener blends vary. "Zero Sugar" aims to attract a younger audience who may view the term "diet" negatively.
Conclusion
The artificial sweeteners used in Pepsi products are not uniform. US Diet Pepsi is primarily sweetened with aspartame, a formulation reinstated after consumer preference. Pepsi Zero Sugar, however, uses a blend of aspartame and acesulfame potassium for a bolder taste. Sucralose is present in some past and international products but is not the main sweetener in current US diet/zero sugar colas. The choice between these depends on taste preference, and checking ingredient labels is key for specific regional formulations.

Q: Does Pepsi Zero Sugar contain the same sweeteners as Diet Pepsi? A: No, Pepsi Zero Sugar uses a blend of two artificial sweeteners: aspartame and acesulfame potassium (Ace-K), which gives it a different taste profile than Diet Pepsi.
Q: Why did Pepsi change the sweetener in Diet Pepsi in the past? A: In 2015, PepsiCo briefly removed aspartame from US Diet Pepsi in favor of sucralose and Ace-K, but due to consumer backlash over the taste, the company reverted to the original aspartame formula in 2018.
Q: Is aspartame safe? A: Aspartame has been deemed safe by major regulatory bodies, including the U.S. Food and Drug Administration (FDA), for consumption at established levels. However, individuals with the genetic condition phenylketonuria (PKU) must avoid it.
Q: What is acesulfame potassium (Ace-K)? A: Acesulfame potassium is an artificial sweetener often combined with others, like aspartame, to create a more balanced and intense sweetness. It is a key ingredient in Pepsi Zero Sugar.
