Theanine

Drug Details

L-theanine is a unique amino acid predominantly found in tea leaves, especially green tea, and certain mushrooms. It is known for promoting relaxation without causing drowsiness, potentially by influencing brain chemicals such as serotonin and dopamine. Some studies suggest that L-theanine may enhance mental focus, improve sleep quality, and reduce stress and anxiety. When combined with caffeine, it might further boost cognitive performance and alertness. While generally considered safe, with doses up to 900 mg daily used in studies lasting up to eight weeks, individuals who are pregnant, breastfeeding, or taking medications should consult a healthcare provider before use.
