Theanín
Theanine is a non-proteinogenic amino acid structurally similar to glutamate and glutamine. Discovered as a constituent of green tea in 1949 and isolated from gyokuro leaves in 1950, it constitutes approximately 1-2% of dried green tea leaves. Used as a nootropic for its calming properties without significant sedation, theanine is frequently combined with caffeine to mitigate stimulant-related anxiety while potentially enhancing attention. It is widely available as a dietary supplement.
