L-Theanín
L-Theanine is a naturally occurring amino acid found primarily in tea leaves. It promotes relaxation without sedation at common doses but may become sedating at strong doses (300+ mg). Often combined with caffeine to reduce anxiety and improve focus while maintaining alertness. Commonly used to mitigate negative effects of stimulants and withdrawal symptoms from GABAergic substances.
