The Perfect Synergistic Combination for Calm Focus and Enhanced Cognitive Performance
L-theanine counteracts caffeine's anxiety-inducing effects while preserving its cognitive benefits, providing smooth, sustained focus perfect for dual n-back training sessions.
The synergistic combination enhances working memory capacity and processing speed, directly benefiting performance in cognitive training tasks that require holding multiple items in memory.
Together, these compounds improve sustained attention and reduce mind-wandering, crucial for maintaining performance throughout extended training sessions.
The combination enhances cognitive flexibility and task-switching abilities, supporting better adaptation to changing patterns in dual n-back training.
L-theanine promotes alpha brain waves associated with relaxed alertness, creating an optimal mental state for learning and cognitive performance.
Multiple studies show that L-theanine (100-200mg) combined with caffeine (50-100mg) significantly improves attention, working memory, and cognitive flexibility compared to either compound alone.
Research demonstrates that L-theanine effectively reduces caffeine-induced anxiety, jitters, and blood pressure increases while maintaining cognitive benefits.
Studies on attention tasks show the combination improves both accuracy and reaction time, with effects appearing within 30-60 minutes and lasting 2-4 hours.
EEG studies reveal that L-theanine increases alpha brain wave activity, associated with relaxed focus and improved cognitive performance.
