What Does Caffeine Do?

Caffeine helps lift energy and focus, and might support performance during tough sessions, and EFSA notes caffeine as a contributor to normal energy-yielding metabolism and mental performance, which fits what athletes usually hear.

Dr Grgic from the University of Zagreb found caffeine to be a solid ergogenic aid for endurance and high-intensity workouts, helping sustain performance in sports contexts.
