The formulation includes carbonated water and sugar, providing the base and sweetness. Acids like citric acid and lactic acid contribute to its tangy profile, while sodium citrate acts as an acidity regulator. Flavourings enhance the taste, and sweeteners such as acesulfame K and sucralose offer additional sweetness without extra calories. Caffeine (0.03%) serves as the primary stimulant, and ascorbic acid functions as an antioxidant. The drink’s distinctive colour comes from Sunset Yellow and Ponceau 4R. Niacin (Vitamin B3) is included to support energy metabolism.
