The drink is formulated with high-quality ingredients to deliver both energy and taste. It contains carbonated water for effervescence, and a combination of sucrose and glucose for sweetness. Citric acid is used to provide a tangy flavor, while taurine (0.4%) supports various physiological functions, including muscular and neurological activity. Caffeine (0.03%) acts as a stimulant to enhance alertness and focus. The beverage also includes B-group vitamins—niacinamide (B3), calcium pantothenate (B5), pyridoxine HCl (B6), and vitamin B12—to support energy metabolism. Natural and artificial flavorings create the distinctive iced vanilla berry taste profile. Additional ingredients like sodium citrate serve as acidity regulators, and coloring agents such as Brilliant Blue FCF give the drink its characteristic appearance. ​

Red Bull Winter Edition Iced Vanilla Berry 250ml is free from the 14 major allergens recognized by UK and EU food regulations, including gluten, dairy, soy, nuts, and eggs. It is also suitable for individuals avoiding genetically modified organisms (GMOs). However, due to its caffeine content, it is not recommended for children, pregnant or breastfeeding women, or individuals sensitive to caffeine. As always, it’s advisable to check the product label for the most accurate and up-to-date allergen and ingredient information, especially if you have specific dietary requirements or sensitivities.
