Caffeine & Health:
Clarifying The Controversies
MENTAL PERFORMANCE
It has long been anecdotally reported that caffeine has the ability to improve alertness and aid in concentration. Recent studies in a number of laboratories have consistently demonstrated increases in key aspects of cognitive function related to alertness, even among well-rested volunteers. Additionally, caffeine enhances self-rated moods such as vigor, efficiency, energy and clear-headedness. These effects are present at consumption levels as low as 32mg (less than an eight-ounce cup of hot tea). [Lieberman, 2001]
