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

In terms of allergens, Pepsi Max No Sugar Cola contains a source of phenylalanine due to the presence of aspartame, which makes it unsuitable for individuals with phenylketonuria (PKU), a rare genetic disorder. However, the product is free from common allergens such as cereals containing gluten, dairy, eggs, fish, nuts, and soy. It is also suitable for vegetarians, vegans, and those following a gluten-free diet. As with any product, individuals with PKU should avoid this beverage because of the phenylalanine content.
