Summary: Excess intake of energy drinks has been linked to heart attacks and sudden death in rare cases. As such, pregnant women, children, people with heart problems, and caffeine-sensitive individuals should avoid Red Bull entirely. More research is needed on how the combination of ingredients may affect risks for heart attack and other serious side effects. One recent study in 34 healthy adults found that drinking 32-ounces (946 ml) of Red Bull daily for 3 days resulted in significant changes to the interval between heartbeats.Ī change in heartbeat rhythm can lead to certain types of arrhythmias that may result in sudden death, especially in those with high blood pressure or heart disease.Īdditionally, researchers claim that these changes in heart rhythm can’t be explained solely by the amount of caffeine but were likely due to the combination of ingredients in Red Bull. Yet, in many of the heart attack and sudden death cases involving energy drinks, individuals drank only 3–8 cans in one day - far fewer than 40 cans. This would mean drinking approximately forty 8.4-ounce (260-ml) cans of Red Bull in one day. While current recommendations call for limiting caffeine to no more than 400 mg per day in healthy adults, cases of caffeine-related deaths have primarily been in individuals with unusually high intakes of 3–5 grams of caffeine per day. Many factors affect how much caffeine you have to consume for it to be dangerous and potentially life-threatening.

Plus, as it contains artificial sweeteners, regular consumption may still increase your risk of type 2 diabetes. Summary: While sugar-free Red Bull is lower in sugar and calories, it packs the same amount of caffeine as regular Red Bull. In fact, research associates regular intake of artificial sweeteners with an increased risk of type 2 diabetes and has its own potential safety concerns and side effects. Sugar-free Red Bull is lower in calories and sugar but has the same amount of caffeine as regular Red Bull and therefore likely the same potential side effects.ĭespite not providing sugar, sugar-free Red Bull may still increase your risk of type 2 diabetes if consumed regularly, as it contains two artificial sweeteners - aspartame and acesulfame K. Still, when consumed frequently and in excess, it may have several negative and potentially life-threatening effects. Summary: Occasional, moderate intake of Red Bull is unlikely to have any serious side effects.
