Helps fight stress

Posted by Reviewer1781073 on Apr 20, 2011

Its a wonderful product. I trust it more since it is Suntheanine. I dont have regular hours to take it. Sometimes I take on cap on an empty stomach and it does help for concentration and relaxation. It is becoming part of my diet. Sometimes I take one in the middle of the night, and it does help me get back to sleep. Also I've noticed its not just sleep, but deep sleep. I will try soon the 200mg version.

Worked Well

Posted by SherryB on Aug 23, 2012

This supplement is often used to help provide a calming sense. When I used them, I liked how they worked. Suntheanine is often said to be the best and the best absorbed form of L-Theanine.

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!

Not strong

Posted by Reviewer3170367 on Jan 24, 2012

This product is not strong at all - actually I didn't feel any kind of effect even after taking 20 capsules which makes a total of 3000mg of l-theanine. Normally I feel a very discernible effect when taking 200-400mg of theanine.

If you have trouble getting to sleep, try this stuff! My husband works night occasionally and this has been a godsend helping him sleep during the day. No side effects!
