Why do people take theanine?

ANSWER

Theanine supplements may help people feel more relaxed and lower anxiety, some early studies have shown. Theanine supplements helped boys with ADHD sleep better in one small study. Another small study showed that when combined with caffeine, theanine may sharpen thinking. More research is needed to see how theanine affects these conditions.
