Red Bull Red Bull Plus Zero Sugar Energy Drink is a refreshing, sugar-free energy beverage designed to deliver a powerful boost without added sugar. It maintains the classic bold Red Bull taste while using low-calorie sweeteners for a lighter, crisp flavor. The drink contains energizing ingredients such as caffeine, taurine, and B-group vitamins (B3, B5, B6, and B12) that help improve alertness, support mental performance, and reduce fatigue. It typically provides about 80 mg of caffeine per 250 ml can, similar to a cup of coffee.
