L-theanine is best taken at specific times to maximize its benefits, particularly for relaxation and focus. The ideal moments include early morning to enhance alertness without jitters, during stressful work hours to promote calmness, and before bedtime to improve sleep quality. Additionally, taking L-theanine alongside caffeine can boost cognitive performance while minimizing the negative effects of caffeine. For those seeking to reduce anxiety, mid-afternoon doses can help maintain a balanced mood throughout the day. Understanding these optimal times can significantly enhance your experience with L-theanine.
