Coca-Cola Zero Sugar is formulated to maintain the iconic Coca-Cola flavour with zero sugar. The ingredients are:
Carbonated Water, Colour (Caramel E150d), Phosphoric Acid, Sweeteners (Aspartame, Acesulfame K), Natural Flavourings (including Caffeine).
The sweeteners used in this formula are carefully chosen to replicate the classic taste while keeping the beverage free of sugar and calories.

Coca-Cola Zero Sugar contains no allergens as defined by UK food allergen regulations. It is gluten-free, dairy-free, nut-free, and suitable for individuals with most dietary restrictions. However, it does contain caffeine, which may not be suitable for children, pregnant women, or those sensitive to stimulants. It also contains aspartame, a source of phenylalanine, so it should be avoided by individuals with phenylketonuria (PKU).
