Diet Coke is made with carbonated water, colour (Caramel E150d), phosphoric acid, sweeteners (Aspartame, Acesulfame K), caffeine, acidity regulator (Sodium Citrate), and preservatives (Potassium Sorbate). These ingredients combine to deliver the classic, crisp, and refreshing Diet Coke taste with zero sugar, making it a low-calorie beverage option.

Diet Coke 18 x 330ml contains no major allergens such as milk, eggs, soy, nuts, or gluten. It does contain a source of phenylalanine due to the presence of aspartame, which is important for individuals with phenylketonuria (PKU). As always, it’s recommended to check the product label for the most up-to-date allergen and ingredient details.
