Question

Quizplus · Accepted Answer

Research suggests that caffeine has the strongest overall effect among the xanthines, as it is the most potent stimulant of the central nervous system and has a longer half-life than other xanthines. It also has a wider range of effects on the body, including improving mental alertness, increasing endurance, and decreasing feelings of fatigue. Theobromine and theophylline have less pronounced effects, and muscadine is not a xanthine.
