"I used to have difficulty in allowing myself to relax and shut down at bedtime. This supplement really helps me in balancing my cortisol levels. Just one pill with dinner, daily. I notice the difference."
"Compared to previous theanine products I've taken that came in a capsule, these Vitacost tablets are larger and have a chalkiness absorption to them that makes them much harder to swallow for me. This is the first house brand product I've had a problem with."
"I'm a surly 51 year old male. I like my job, but hate where I work. I recently added this to St. Johns Wort and think it has calmed down the lingering anxiety working with the company president (a complete tool) - kind of like leftover hypnosis in the movie Office Space."
"I take one or two tablets at bed time. If I wake up during the night, my mind no longer goes into spinning thoughts that keep me awake. The theanine keeps my mind quiet and it is much easier to relax and go back to sleep."
"For me the Suntheanine capsules are more effective and sustain effectiveness longer. I can imagine several possible reasons for this and if I am able to pin it down I will submit another review. Sometimes formulation differences and purity issues loom large."
