Theanine is a water-soluble amino acid primarily found in tea, Camellia sinensis. Theanine is able to cross the blood-brain barrier and may promote relaxation, balanced stress levels and mental focus. A structural analog to the excitatory neurotransmitter glutamate, theanine has been shown to promote alpha wave production in the brain and increase brain dopamine levels. Additionally, more recent research has explored the synergistic effect of l-theanine and caffeine on memory, attention, cognition and mood.
