About
When paired with caffeine, L-Theanine may help to reduce feelings of anxiety and improve focus and attention. This is why many people describe feeling a calm uplift when consuming green tea over other caffeinated beverages such as coffee. L-Theanine improves alertness and reduces fatigue, while reducing the feelings of brain fog.
A review of human studies shows it helps to reduce feelings of stress and anxiety in people experiencing stressful situations.
Another review of recent studies suggests that Green Tea (L-Theanine) may improve attention, working memory, mental flexibility and even self-control.
Furthermore, after four weeks of supplementation with L-Theanine, individuals showed a reduction in sleep disturbances, stress related functions and a significant improvement in cognitive functioning. These findings suggest that it has the potential to support optimal brain health in the general population.
