Medical professionals have sounded the alarm on the potentially devastating impact of consuming large volumes of caffeine-laden energy drinks.

This concern comes to the forefront following a lawsuit filed earlier this month against energy drink distributor Alani Nu. The legal action, initiated by the Rodriguez family, addresses the tragic death of their 17-year-old daughter, Larissa, in October.

Larissa, an accomplished high school student and cheerleading leader in Texas, reportedly succumbed to an enlarged heart, allegedly due to chronic caffeine intake from Alani Nu drinks, as per the lawsuit. Her family’s attorneys argue that she had no pre-existing health conditions.

Each Alani Nu energy drink contains 200mg of caffeine, which is double the daily caffeine limit recommended by the American Academy of Pediatrics for teenagers and constitutes half of the advised maximum for adults.

Celsius Holdings Inc., the parent company of Alani Nu, responded by stating that their products clearly indicate the 200mg caffeine content on the can. Moreover, labels advise against consumption by children, individuals sensitive to caffeine, pregnant women, or nursing mothers.

The Daily Mail has requested a statement from Alani Nu regarding the matter.

‘Our products comply with applicable federal labeling requirements, and our policy is not to market or sample to anyone under 18, consistent with those label warnings,’ the statement also read.  

Larissa’s death also comes after a series of lawsuits surrounding Panera’s ‘charged’ lemonades, which contained 390mg of caffeine – almost a full day’s worth for an adult and four times the limit for teens – in a large size before they were pulled from menus.

At least two deaths were allegedly tied to the drinks, including a college student with a heart condition. Panera denied wrongdoing in court documents and settled the lawsuits. 

Doctors told the Daily Mail that while a one-off energy drink may be harmless for most people, regularly consuming the drinks could lead to deadly damage to the heart, stomach and brain. These effects are also exacerbated in teens, as their bodies are still developing and are more sensitive to the stimulant effect of caffeine.  

‘If you consume very high amounts of caffeine, you can have an instant arrhythmia or irregular heartbeat, which can actually be life-threatening because your heart could actually stop pumping blood,’ Dr Jeremy Liff, a neurologist based in New York, told the Daily Mail. 

Caffeine speeds up the heart’s beating pattern, which places stress on the organ and can affects its overall rhythm. Arrhythmias disrupt the electrical signals the heart requires for pumping, leading to poor blood flow to the heart and other vital organs. 

Left unaddressed, irregular heartbeats can trigger a sudden heart attack, even in people without pre-existing conditions.  

Liff also warns that the poor blood flow from irregular heartbeats raises the risks of blood clots, which may travel to the brain and trigger a stroke. 

Blood pressure is also a concern. 

‘In the long term, drinking that much caffeine can cause you to have high blood pressure at an age which is way too young,’ Liff said. 

Caffeine stimulates the nervous system to release adrenaline, which blocks adenosine receptors that are responsible for keeping the arteries widened. This raises blood pressure, increasing the heart’s workload. 

‘Those are extremely grave consequences that could happen immediately,’ Liff said. 

For people with a pre-existing heart condition, caffeine tolerance dwindles. In 2022, college student Sarah Katz of New Jersey suffered a cardiac arrest after consuming one of Panera’s Charged lemonades. 

Sarah Katz (pictured) died on September 10, 2022, just hours after she consumed a large Panera Charged Lemonade from a branch of Panera Bread in Philadelphia. Panera denied wrongdoing but settled the lawsuit

Court documents said Katz had long QT syndrome, which causes arrhythmias due to a delayed electrical recharge between beats. Caffeine can eliminate the vital breaks people with long QT syndrome need for their hearts to recharge between beats. 

Panera settled that lawsuit but denied wrongdoing.   

‘If you have an irregular heartbeat already that leads to your heart going too fast, you would be much less tolerant to caffeine,’ Liff said. 

‘And if you have an irregular heartbeat, you shouldn’t be drinking any energy drinks at all whatsoever.’ 

Liff also points to highly caffeinated drinks damaging the gastrointestinal system. 

‘You can harm your stomach lining and cause ulcers, which can lead to a decrease in absorbing nutrients,’ he told the Daily Mail. 

Caffeine stimulates the production of stomach acid. While the acid is essential for breaking down nutrients and aiding digestion, high levels irritate the stomach lining, leading to inflammation and the formation of ulcers.

Many ulcers heal on their own, they can perforate or tear, allowing acid, food and bacteria to leak through a hole in the stomach into the abdominal cavity that then spreads to the bloodstream. 

This may result in sepsis, the body’s overreaction to an infection that causes the immune system to mistakenly attack healthy organs and tissues. 

Sepsis, which kills 300,000 Americans every year, or one every 90 seconds, can cause multi-organ failure and long-term complications such as amputations. 

Liff told the Daily Mail that there are ‘red flag’ signs a person may notice if they need to cut back on caffeine. 

‘If you find that you are having a lot of trouble sleeping, have a tremor, are sweating throughout the day, if your blood pressure is high and you’re under the age of 40, there’s absolutely no reason that should be the case.

‘These are all signs that you’re drinking too much caffeine.’
