Reducing nervousness and restlessness just got easier

I have been using Zen Theanine for approximately 2 weeks before going to bed. My sleep quality has improved, as has my ability to fall asleep quickly. I have also taken it during the day a few times and was pleasantly surprised that I experienced no drowsiness. It has a calming effect as stated. I also like the fact that you only have to take 1 capsule. I will definitely purchase this again!
