Diet Pepsi is made with carbonated water, colour (Caramel E150d), phosphoric acid, sweeteners (Aspartame, Acesulfame K), natural flavourings including caffeine, acidity regulator (Sodium Citrate), and preservative (Potassium Sorbate). Its crisp taste is achieved through a careful blend of natural flavours and sweeteners, delivering maximum refreshment without the sugar.

Diet Pepsi contains no major allergens such as milk, eggs, nuts, soy, or gluten. However, it does contain a source of phenylalanine due to the presence of aspartame, which is important information for individuals with phenylketonuria (PKU). As always, it’s recommended to check the label for the most accurate and current allergen and ingredient information.
