Theanine may help reduce the negative effects of stress, according to a small study published in Biological Psychology in 2007. In an experiment involving 12 people, researchers found theanine-treated participants were less likely to experience an increase in heart rate when performing a stressful task.

Researchers found that the combination of theanine and significantly improved accuracy and alertness and helped to increase focus while performing the task.

Additionally, findings from an animal-based study published in Free Radical Biology & Medicine in 2009 suggest that theanine may inhibit buildup of amyloid beta (a substance that forms the brain plaques associated with Alzheimer's disease).

4) Depression

Theanine may help relieve depression, according to an animal-based study published inPhytotherapy Research in 2011. In tests on mice, scientists discovered that theanine produced an "antidepressant-like effect."
