I am a grad student and this helps me to relax before giving my long in class presentations. Takes away the edge and helps me to stay focused!

It works!

I feel better just knowing I have this in my purse. I feel de-stressed and more at peace without that chemical dullness or artificial buzz like you get with other prescription meds for stress/depression. 150mg is the perfect amount per capsule, not too much and not too little. It just take the edge off and reduces the paranoia I feel that everyone and everything is going wrong.

The best on the market!

This L-theanine is the best I have tried! I have tried several brands and I am convinced this is the purest,highest quality product. I've seen what a 99% pure L-theanine looks like and tastes from another well know company. It is pure white with neutral taste. Many other companies cut there L-theanine with some junk but not Doctor's Best. The calming effects and pleasant energy are much more pronounced with this quality product!

Just as it says on the package. Relaxation without drowsiness. Perfect if you feel too stressed and need to get things done.

I am sleeping better!

Posted by Reviewer2248925 on Mar 07, 2012

I have not been taking this product long enough to perceive all that it can do(that is the reason for the 4 out of 5 stars), but I am noticing that I am sleeping better and more soundly. Also, the anxiety, almost panic sometimes, seems to be better. The Suntheanine is the only one to get according to all that I have read. Thank you very much!

I dont have the sleepy effects that everyone says they have...in order for me to be sleepy and relaxed need to take high doses of it.
