Energy drinks are quite popular among adolescents, students, athletes, and even working professionals who use them for a quick energy boost. Now, a Texas family has alleged that their 17-year-old daughter has died from an enlarged heart caused by ingesting large amounts of caffeine present in a popular energy drink. Larissa Nicole Rodriguez, a college-bound high school student in Weslaco, Texas, died in October last year. According to her family’s attorney, Benny Agosto Jr., Rodriguez often drank Alani Nu energy drinks, which “had inadequate warnings about the serious cardiac risks that this product brings”, NBC News reported.As per Agosto, Rodriguez began drinking energy drinks after being influenced by social media posts that advertised them for their wellness and health benefits, in addition to an energy boost. The family has filed a lawsuit against the distributors Glazer’s Beer and Beverage and Glazer’s Beer and Beverage of Texas, and is seeking more than $1 million in damages. During a press conference, Agosto noted that Rodriguez had no pre-existing heart conditions or heart-related problems. He added that the medical examiner tested for myriad drugs and that “everything was negative, not one trace of alcohol or anything. The only thing she had in her system was caffeine.” How Much Caffeine Is HealthyThe US Food and Drug Administration permits 400 mg of total daily maximum of 400 mg of caffeine for healthy adults, and less than 100 mg of caffeine per day for children and teenagers ages 12 to 17. However, Alani Nu’s drinks contain a far higher concentration of caffeine than some other popular energy drinks on the market, the report said. Celsius Inc., which owns Alani Nu, in a statement said that it is “saddened by this loss, and our thoughts are with the family. We take product safety seriously and believe consumers should have clear information about what they are drinking.” “Alani Nu energy drinks disclose 200mg of caffeine on the can, and the label states the product is not recommended for children, people sensitive to caffeine, pregnant women, or women who are nursing,” the statement said. “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.” What Are The Health Risks Posed By Energy Drinks According to the World Health Organization (WHO), too much consumption of energy drinks is on the verge of becoming a major public health problem. A 2025 study published in Frontiers stated that regular consumption of energy drinks, especially sugar-free varieties, may damage the brain's protective barrier (blood-brain barrier) and trigger inflammation. The study, conducted on mice, also linked these apparent "health drinks" to neurodegenerative diseases such as Alzheimer's and multiple sclerosis. Other studies have shown that the short-term effects of ingesting high amounts of caffeine are increased heart rate, nervousness, palpitations, and dehydration. Energy drinks have also been known to cause: Cardiac arrhythmias Hypertension Seizures Psychosis Sudden cardiac arrest These dangers are compounded when energy drinks are consumed with alcohol. Caffeine can conceal the symptoms of intoxication, making alcohol poisoning more likely. Although fatalities directly linked to energy drinks are still uncommon, they are occurring often enough to raise legitimate alarm among health professionals and scientists alike. Despite growing evidence, laws governing the promotion and production of energy drinks are lax, particularly in the United States and Europe. Experts from the WHO, in the 2025 review, advocated stricter regulation—including establishing a maximum amount of caffeine per serving, labeling of warning messages, and public awareness of the risks of combining energy drinks with alcohol.
