The drink is crafted with carbonated water and includes taurine (0.4%) to enhance energy levels. Citric acid and sodium citrate are added for acidity regulation, while natural flavourings provide the distinctive apple and raspberry taste. Sweeteners such as sucralose and acesulfame K replace sugar, offering sweetness without the calories. Fruit and vegetable concentrates from carrot and blackcurrant contribute to the beverage’s colour. Caffeine (0.03%) is included to improve alertness, and sodium benzoate acts as a preservative. The drink is fortified with vitamins—niacin, pantothenic acid, vitamin B6, and vitamin B12—and contains inositol to support energy metabolism. ​
