Additionally, Red Bull has sugar-free options, including Red Bull Zero and Red Bull Sugarfree, which are made with the artificial sweeteners aspartame and acesulfame K instead of sugar ( 3). And so for every single Ocean Bottle sold, we fund the collection of 1000 plastic bottles before they enter the ocean. While the exact composition varies by country, additional ingredients in Red Bull include sugar, carbonated water, baking soda, citric acid, magnesium carbonate, glucuronolactone, and artificial colors and flavors ( 1). 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 ( 28, 31). These increases in heart rate and blood pressure are thought to be largely due Red Bull’s caffeine content, as one large 12-ounce (355-ml) can contains 108 mg of caffeine — about the same amount as a cup of coffee ( 2, 10, 11).
Additionally, 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 ( 39).I struggled massively. Since Lap 1, I ran out of water, I couldn't drink at all," he said, when he finally had the strength to speak to Jenson Button for a post-race interview. "I think by the middle of the second stint it was starting to get pretty difficult, losing strength. I think my toughest ever physically," he shared. One 5-day test-tube study found that exposing human tooth enamel to energy drinks for 15 minutes, 4 times a day resulted in significant and irreversible loss of tooth enamel ( 17). It’s also high in several B vitamins, including thiamine (B1), riboflavin (B2), niacin (B3), B6, and B12 ( 2). Additionally, adolescents under the age of 19 may be at a greater risk of caffeine-related side effects ( 30).
When consumed together, caffeine in Red Bull can mask the effects of alcohol, making you feel less intoxicated while still experiencing alcohol-related impairments ( 22, 23, 24). Current recommendations call for limiting caffeine to 100 mg or less per day in adolescents aged 12–19. Therefore, drinking more than one 8.4-ounce (260-ml) serving of Red Bull could increase the risk of caffeine overdose in this age group ( 28). Symptoms of caffeine overdose and toxicity can include nausea, vomiting, hallucinations, anxiety, rapid heart rate, dizziness, trouble sleeping, and seizures ( 31). Summary As Red Bull is sugar-sweetened — providing 29 grams of sugar in one 8.4-ounce (260-ml) serving — drinking one or more servings per day could increase your risk of type 2 diabetes ( 2). May damage your teethA 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 ( 39). However, the average half-life of caffeine in the blood ranges from 1.5–9.5 hours, which means it could take up to 9.5 hours for your caffeine blood levels to drop to half of its original amount ( 29).
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 ( 39). Even when not paired with alcohol, observational studies indicate that in young adults, regular intake of energy drinks like Red Bull is linked to an increased risk of alcohol dependence and illicit drug use ( 22, 26, 27).

Despite these increases, moderate and occasional intake of Red Bull is unlikely to cause serious heart problems in healthy adults. Research has shown an association between drinking Red Bull and increased high-risk behavior, especially when combined with alcohol ( 1). First sold in 1987 in Austria, Red Bull is a carbonated beverage containing caffeine, as well as other energy-boosting compounds, including several B vitamins and taurine ( 1). As one small 8.4-ounce (260-ml) can of Red Bull provides 75 mg of caffeine, drinking more than 5 cans per day could increase your risk of caffeine overdose ( 2).
Though Red Bull remains a popular beverage, research suggests that it may negatively affect your health. Can increase blood pressure and heart rate One study found that college-aged students who drank energy drinks and alcohol together were more likely to drink and drive and experience serious alcohol-related injuries than when alcohol was consumed alone ( 25). Several studies in healthy adults have shown that drinking one 12-ounce (355-ml) can of Red Bull significantly increased blood pressure and heart rate levels within 90 minutes and up to 24 hours after consumption ( 6, 7, 8, 9). While occasionally drinking Red Bull is unlikely to have any serious effects on kidney health, research suggests that chronic and excessive intake could.
