L-theanine, an amino acid found in tea leaves, helps reduce holiday stress, promote relaxation and improve the quality of sleep. L-theanine is found in tea leaves in low concentrations (less than 2 percent), which means that effective dosage levels (of 100 – 200mg/day) cannot be delivered from drinking tea alone… if you have holiday high anxiety try 200 mg of L-theanine per day.
Test results show that highly anxious students during final exams receiving L-theanine displayed a slowing of their heart rate, improved attentional performance, and better reaction times, compared to members of the same group receiving placebo.
L-theanine does not result in increased drowsiness, slowed reflexes, or impaired concentration … about 200 mg of L-theanine changes the electrical activity in the brain by increasing alpha electric band measured by EEG.
