The ingredients in Pepsi Max No Sugar Cola include carbonated water, caramel (E150d) for colouring, and sweeteners such as aspartame and acesulfame K, which provide the sweetness without adding calories. The product also contains acids like phosphoric acid and citric acid for tartness, as well as flavourings, including caffeine, which contributes to its bold cola taste. Potassium sorbate is used as a preservative to maintain the product’s freshness over time.

Regarding allergens, Pepsi Max No Sugar Cola contains phenylalanine due to the aspartame content. This makes it unsuitable for individuals with phenylketonuria (PKU), a rare genetic disorder that affects the body’s ability to process phenylalanine. However, the product is free from other common allergens, including gluten, milk, eggs, fish, nuts, and soy. It is also suitable for vegetarians, vegans, and those following a gluten-free diet. Despite the presence of phenylalanine, it remains a great sugar-free and low-calorie alternative to regular cola for most people.
