Organika L-Theanine 225 mg Vegetarian Capsules 90count

L-theanine is a naturally occurring amino acid analogue of glutamate that helps to promote relaxation without adding any components that promote drowsiness. As a result, L-theanine supplementation can help to “take the edge off” of stimulant supplements like caffeine for a more balanced effect. It can also help people fall asleep quicker and easier not by acting as a sedative but by lowering anxiety and promoting relaxation. L-theanine has also been used to help improve mental focus, learning and concentration. (Less stress means there are lower cortisol and corticosterone levels in the body, which affect our cognitive functions.) Due to its calming effects, L-theanine lowers heart rate and blood pressure.
