May increase type 2 diabetes riskĮxcess sugar intake, especially from sweetened beverages, may increase your risk of type 2 diabetes ( 14). Still, excess intake - particularly in younger people - has been linked to abnormal heart rhythm, heart attack, and even death ( 11, 12, 13).Īdditionally, while research is limited, drinking Red Bull could worsen heart health and be life-threatening in individuals with pre-existing high blood pressure or heart disease ( 11). 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).ĭespite these increases, moderate and occasional intake of Red Bull is unlikely to cause serious heart problems in healthy adults. 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). Can increase blood pressure and heart rateīlood pressure and heart rate are two important measures for heart health, as increased levels have been associated with a higher risk of hypertension (high blood pressure) and heart disease ( 4, 5). Though Red Bull remains a popular beverage, research suggests that it may negatively affect your health. Possible side effects of drinking Red Bull

Due to its combination of ingredients, there are concerns over its potential side effects, especially when consumed in larger amounts. Red Bull is a sugar-sweetened, caffeinated drink marketed as a way to boost mental and physical performance. While the ingredients in Red Bull may provide a boost of energy, they may also cause short- and long-term side effects - especially in larger quantities.

It’s also high in several B vitamins, including thiamine (B1), riboflavin (B2), niacin (B3), B6, and B12 ( 2).Īdditionally, 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). 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). 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).
