The Sweeteners in Regular Pepsi
For the classic, full-calorie flavor, the sweetener used in Pepsi varies based on location. In the United States, regular Pepsi is sweetened primarily with a combination of high-fructose corn syrup and sugar. However, in many other countries, including much of Europe and Australia, PepsiCo has reformulated its regular cola to significantly reduce sugar content. These reformulated versions use a blend of sucralose and acesulfame potassium (Ace-K) to maintain sweetness while lowering calories. This move was driven by consumer health trends and the implementation of sugar taxes in various regions.
Sweeteners in Diet and Zero Sugar Pepsi
For zero-calorie options, Pepsi consistently uses artificial sweeteners. The composition is generally a blend to create a taste profile closer to sugar and avoid the aftertaste associated with single artificial sweeteners.
- Diet Pepsi: The main sweetener in the U.S. is aspartame, combined with acesulfame potassium (Ace-K). PepsiCo briefly removed aspartame from some Diet Pepsi formulations around 2015 but reintroduced it in 2016 due to consumer preference. For those with phenylketonuria (PKU), the presence of aspartame means this product should be avoided.
- Pepsi Zero Sugar / Pepsi Max: This product uses the same combination of artificial sweeteners as Diet Pepsi, namely aspartame and acesulfame potassium. The key difference between Diet Pepsi and Pepsi Zero Sugar is marketing, with Zero Sugar positioned for a broader, typically male audience that may be less inclined to purchase a product labeled "diet".

Common Sweeteners Used by Pepsi: A Closer Look
High Fructose Corn Syrup (HFCS)
- HFCS is a sweetener derived from corn syrup and used widely in processed foods and sodas.
- It contains a mix of fructose and glucose, similar in ratio to table sugar.
- The health debate around HFCS vs. sugar is ongoing, with some studies showing minimal differences in metabolic effect, while others link high fructose intake to health risks.
Aspartame
- Aspartame is an artificial sweetener made from two amino acids, aspartic acid and phenylalanine.
- It is about 200 times sweeter than sugar and has minimal calories.
- The World Health Organization reclassified aspartame as “possibly carcinogenic” in 2023, though the acceptable daily intake remains high.
- It is unsafe for individuals with the rare genetic disorder phenylketonuria (PKU).
Sucralose and Acesulfame Potassium (Ace-K)
- Sucralose is a zero-calorie artificial sweetener, often known by the brand name Splenda, and is about 600 times sweeter than sugar.
- Acesulfame potassium (Ace-K) is another zero-calorie sweetener often used in combination with sucralose or aspartame.
- Both sweeteners are heat-stable, making them suitable for baking, unlike aspartame.
- Recent studies have raised concerns about sucralose's potential impact on gut health and metabolism.
Health Implications of Pepsi Sweeteners
Consumers are increasingly concerned about the health effects of both sugar and artificial sweeteners, prompting changes in the soft drink industry. For those who consume regular, sugar-sweetened Pepsi, the primary health concern is the high intake of sugar, which is linked to an increased risk of obesity, type 2 diabetes, and other health issues.
For diet sodas containing artificial sweeteners, the health picture is more complex. While generally considered safe by regulatory bodies like the FDA, ongoing studies and some research raise questions about long-term consumption. Studies have looked at links between artificial sweeteners and conditions like metabolic syndrome, effects on the gut microbiome, and cancer risk, often yielding conflicting results. The World Health Organization (WHO) has also advised against using non-sugar sweeteners for long-term weight control, citing insufficient evidence of benefit and potential risks.
Ultimately, the choice of sweetener and potential health impacts depend on individual metabolism and consumption patterns. For more information on artificial sweeteners, resources like this guide from Everyday Health can offer further insights. Regular or excessive consumption of any heavily sweetened beverage, whether with sugar or artificial sweeteners, can have potential health consequences, and moderation is key. The rise of new, lower-sugar products like Pepsi's Prebiotic Cola is a testament to the changing market, with companies responding to consumer demand for healthier options.
Conclusion
The type of sweetener in a can of Pepsi is not uniform and depends on the specific product and geographical market. Regular Pepsi in the U.S. and some regions uses a combination of high-fructose corn syrup and sugar, while reformulated versions in Europe and elsewhere use a blend of sucralose and acesulfame potassium. All zero-calorie Pepsi products—including Diet Pepsi and Pepsi Zero Sugar—rely on artificial sweeteners, primarily a combination of aspartame and acesulfame potassium. As consumer preferences shift, PepsiCo is continuing to experiment with new, lower-sugar options. Ultimately, understanding which sweetener is in your soda depends on reading the ingredients list and being aware of regional variations.
