By increasing the availability of these chemicals, Modalert helps users stay awake, reduce mental fatigue, and maintain sustained focus on tasks. Additionally, it is believed to improve cognitive flexibility and working memory, making it popular among individuals seeking to optimize productivity and performance. However, its effects and safety can vary, so it is crucial to use it responsibly and under medical supervision.
