The family of a 17-year-old student-athlete has filed a wrongful death lawsuit, alleging that excessive caffeine consumption from a popular energy drink led to her fatal heart condition.
Larissa Nicole Rodriguez, described as a cheerleader, tennis player and honors student, died in October 2025. According to the lawsuit, her death was caused by cardiomyopathy linked to high caffeine intake. The suit, filed in Hidalgo County, names distributor Glazer’s Beer and Beverage and its Texas affiliate as defendants, accusing them of failing to adequately warn consumers about potential health risks.
According to court filings, Rodriguez consumed at least one can daily of Alani Nu energy drink in the months leading up to her death. Each 12-ounce can contains approximately 200 milligrams of caffeine double the recommended daily limit for teenagers.
Her family’s attorney, Benny Agosto Jr., argued that the drink was “defectively designed” and marketed without sufficient warnings about cardiac risks, particularly to young consumers. He also pointed to social media marketing strategies, claiming the brand targeted young women through influencers, contributing to Rodriguez’s regular consumption.
The Hidalgo County medical examiner determined Rodriguez died from an enlarged heart caused by stress and high caffeine intake, according to the lawsuit. Cardiomyopathy is a condition that affects the heart’s ability to pump blood effectively and can lead to serious complications, including heart failure or sudden cardiac arrest. Medical experts say excessive caffeine can elevate heart rate and, over time, contribute to heart strain. Adolescents may be particularly vulnerable due to lower body mass and faster metabolism.
Celsius Holdings, which owns Alani Nu, said in a statement that it complies with federal labeling requirements and clearly discloses caffeine content on its products. The company also noted that its drinks are not recommended for children, individuals sensitive to caffeine, or pregnant or nursing women, and said it does not market to those under 18.
The U.S. Food and Drug Administration advises that adults consume no more than 400 milligrams of caffeine daily, while pediatric health authorities recommend teens limit intake to no more than 100 milligrams per day.
The case adds to increasing scrutiny of highly caffeinated beverages. In recent years, other companies have faced lawsuits over similar claims, including cases involving high-caffeine drinks linked to cardiac events. Rodriguez’s family is seeking at least $1 million in damages. Their attorney indicated that additional defendants, including manufacturers, could be added as the case develops.
