bolt Effectiveness for goals
L-Theanine is an amino acid often used to promote relaxation without causing drowsiness. It is also frequently taken to support focus and attention. Some individuals use it to help manage stress and improve mood.
Research suggests that L-Theanine may help reduce feelings of stress and anxiety in some individuals. It is thought to do this by promoting alpha brain wave activity, which is associated with a relaxed but alert mental state. This effect can contribute to a sense of calm.
L-Theanine does not typically act as a sedative, but it may improve sleep quality by promoting relaxation and reducing anxiety, which can make it easier to fall asleep.

For example, 100-200 mg of L-Theanine might be paired with 100 mg of caffeine. This combination is designed to balance caffeine's stimulatory effects with L-Theanine's calming properties.
