Red Bull

In 2014 a $13 million settlement was reached in two consumer class action lawsuits that allege Red Bull misrepresents the functionality and safety of its Red Bull energy drinks. The class action lawsuit took issue with the beverage maker's promises that "Red Bull gives you wings" and that it "vitalizes body and mind" due to its unique mixture of ingredients that could supposedly improve a consumer's mental and physiological performance. However, the plaintiffs allege Red Bull is no more effective than a cup of coffee or a caffeine pill.
