The side effects of a Red Bull energy drink may include heart palpitations, headaches, tremors, dizziness, chest pain, insomnia, numbness or tingling, agitation, respiratory distress and stomach aches, according to Caffeine Informer. All side effects of energy drinks vary by individual and the level of consumption. When consumed in large amounts or by an unhealthy individual, Red Bull may result in minor health problems.
Different ingredients within the energy drink, including caffeine and ginseng, all have different potential side effects on individuals, according to Caffeine Informer. Caffeine alone has many potential side effects like high blood pressure, excessive urination and headaches. Another major concern is the high content of sugar and artificial sweeteners, which can lead to weight gain if consumed in large quantities.
One of the chemicals in Red Bull with potential for serious side effects is ginseng. The chemical has been linked to restlessness, irritability and nausea, according to Medical News Today. Red Bull should be avoided by pregnant women because the side effects of the ginseng may have an aggravated effect on them.
Aside from caffeine and ginseng, no other chemical in Red Bull has been shown to have a lasting or significant side effect on people as a whole. The chemical inositol may cause diarrhea in large quantities, but Caffeine Informer suggests that any other side effect from Red Bull probably has to do with a pre-existing condition within an individual.
