Theanine, L-Theanine

Theanine is believed to be the primary component of green tea that provides a relaxing effect. Theanine is an amino acid derivative of glutamine. Oral doses of 50 and 200 mg of theanine given to healthy volunteers promoted alpha brain wave production. Alpha waves are associated with a calm mental state. Theanine helps to induce a state of calm relaxation.
