First discovered as a constituent of green tea leaves (Camellia sinensis) and is an an amino acid analogue of the proteinogenic amino acids L-glutamate and L-glutamine. L-Theanine is considered a non-dietary amino acid, not unlike L-Ornithine or L-Citrulline. L-Theanine is primarily known for its ability to promote relaxation without causing sleep and is often paired with Caffeine.
