The beverage is crafted from carbonated water and glucose syrup (11%), providing a primary energy source. It includes orange juice from concentrate (6%) for its distinctive citrus flavor. Citric acid is added for tartness, while sodium gluconate serves as an acidity regulator. Flavorings enhance the taste profile, and potassium sorbate acts as a preservative to maintain freshness. Sweeteners such as sucralose and acesulfame K are used to provide sweetness without excessive sugar content. Acacia gum functions as a stabilizer, and caffeine is included for its stimulating effects. Ascorbic acid (Vitamin C) serves as an antioxidant, and niacin (Vitamin B3) contributes to energy metabolism. Beta carotene imparts the characteristic orange hue. ​
