L-Theanine is a unique amino acid present almost exclusively in the tea plant (Camellia sinensis).* Theanine helps maintain a sense of well-being and increases alpha brain wave activity, a sign of induced relaxation.* It may help ease occasional nervous tension and irritability, without drowsiness.* In addition to its relaxation benefits, L-Theanine may also help support blood pressure within the normal range, nighttime sleep quality, and cognitive performance in healthy adults.*
