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.

Seems to work pretty well

I didn't notice how well this stuff worked until I forgot to take it one day and turned into kind of a space ace. Suntheanine is supposed to be more effective than regular plain L-Theanine. I've tried both and I suppose it is a little better.

Amazing international delivery from IHERB. Outstanding product at a good price. I use it ahead of major presentations and it certainly helps to combat tension and anxiety. Works even better in conjunction with GABA. United Kingdom

Take it on an empty stomach. Great for getting you to an alert state but not agitated.

LOVE, LOVE THESE LITTLE WHITE CAPSULES! They really help me stay calm and focus during stressful situations at work. I take one every day, but on really stressful days I take 3. I gave a few to my sister who is currently under a lot of stress seeking employment. She was so impressed, she went out and bought a bottle at a local health food store for 3 times the price i paid on iHerb.
