Medical experts warn students against excessive use of cognitive supplements during exams

Medical experts, including neurologist Guillermo Garcia Ribas from the Spanish Society of Neurology (SEN), have warned students against the excessive use of stimulants and supplements during exam periods. According to reports cited by the Spanish news agency Efe, there is no scientific evidence that any dietary supplement improves the cognitive performance required for academic success. Experts note that while students often turn to vitamins, energy drinks, and caffeine to manage stress and improve concentration, these products do not replace the need for genuine learning. The consumption of energy drinks is specifically discouraged due to their high sugar and caffeine content. A group of students from Rey Juan Carlos University in Alcorcón confirmed that they frequently increase their caffeine intake, particularly during late-night study sessions. Doctors emphasize that these habits can be physically and neurologically harmful. The advisory highlights that over-reliance on such substances creates health risks without providing tangible academic benefits.
