Energy drinks are known to increase mental and physical performance which is why they’re consumed at such a gross rate.

Moreover, energy drinks include ingredients like sugar and caffeine in high doses which can be bad for you. In fact, energy drinks like Red Bull have been associated with several side effects which include:

  • May increase your blood pressure levels and heart rate.
  • Can increase the chance of encountering type 2 diabetes.
  • Can cause damage to your teeth.
  • Can lead to a negative effect on your kidney health.
  • May increase high-risk behavior, especially among teenagers.
  • Can cause caffeine overdose and possible toxicity.

May Increase Your Blood Pressure Levels And Heart Rate

Blood pressure and heart rate are two of the most crucial measures for heart health, and as high levels of both of them have been associated with an increased risk of hypertension (high blood pressure) and heart disease.

Many studies in healthy adults have proved that if you drink one can of Red Bull every day, it could significantly increase your blood pressure levels and heart rate levels within 90 minutes after consumption and can last up to 24 hours.

These increased levels are thought to be primarily due to the caffeine content of Red Bull, as one 12-ounce (355-ml) can include 108 mg of caffeine.

Despite of these increased levels, moderate and frequent consumption of Red Bull is unlikely to induce any serious heart problems in healthy adults.

However, excessive intake, especially in young people, has been connected to irregular heart rhythm, heart attack, and even death.

Furthermore, while research may be limited, having a regular intake of Red Bull could worsen heart health and possibly be life-threatening in people with pre-existing high blood pressure or any heart disease.

Can Increase The Chance of Encountering Type 2 Diabetes

Excessive sugar consumption, especially from sugar-sweetened beverages, can significantly increase the risk of type 2 diabetes.

In fact, a review study including a number of adults found that the consumption of 1–2 servings of sugar-sweetened beverages every day was linked with a significant 26% increased risk of type 2 diabetes.

As Red Bull is a popular sugar-sweetened beverage that provides 27 g of sugar per one 8.4-ounce (260-ml) serving, if you drink one or more servings per day, your chances of getting type 2 diabetes will increase significantly.

Can Cause Damage to Your Teeth

A number of researchers suggested that if you consume acidic beverages, it may cause damage to your tooth enamel, which is a hard outer layer that protects your teeth against decay.

As Red Bull is an acidic beverage, chronic intake may harm your tooth enamel.

A 5-day test-tube study concluded that if you expose your human tooth enamel to energy drinks for at least 15 minutes and 4 times a day, it could significantly damage your tooth enamel.

In addition, the study also noted that energy drinks can be twice as damaging to tooth enamel compared to soft drinks.

May Cause A Negative Effect On Your Kidney Health

While occasional intake of Red Bull is unlikely to cause any serious effects on your kidney health, some research indicates that regular and excessive intake could.

In fact, a 12-week study including rats showed that chronic consumption of Red Bull can induce a decline in kidney function.

In addition, much research also suggests a connection between high sugar intake and a greater risk of chronic kidney disease.

As Red Bull includes high doses of sugar, chronic and excessive consumption can increase your risk.

May Increase High-Risk Behavior, Especially Among Teenagers

Several types of research have indicated a link between consuming Red Bull and greater high-risk behavior, especially when energy drinks are combined with alcohol.

When energy drinks are combined with alcohol, caffeine in Red Bull may mask the depressant effects of alcohol, which will make you feel less intoxicated, however, you’ll still be experiencing alcohol-linked impairments.

One study showed that college-aged students who consumed energy drinks and alcohol combined were prone to drink and drive and experience serious injuries related to alcohol as compared to when alcohol was consumed alone.

However, even if you don’t pair energy drinks with alcohol, observational studies suggested that daily consumption of Red Bull is connected to an increased risk of alcohol dependence and illicit drug use.

Can Cause Caffeine Overdose And Possible Toxicity

While a safe dose of caffeine varies from person to person, some research suggests people limit their regular caffeine to 400 mg less.

As an 8.4-ounce (260-ml) can of Red Bull includes 80 mg of caffeine, consuming more than 5 cans every day could increase your risk of caffeine overdose.

Additionally, adolescents who’re under the age of 19 are at a greater risk of caffeine-related side effects, if they keep a regular intake of more than five cans of Red Bull.

Here’s a list of symptoms of caffeine overdose and toxicity:

  • Nausea.
  • Vomiting.
  • Hallucinations.
  • Anxiety.
  • Rapid heart rate,
  • Dizziness.
  • Trouble sleeping.
