Seems effective

Posted by Reviewer2457535 on Jan 24, 2010

One of these on an empty stomach produces a noticeable calming effect. I'm fairly sure it's not just placebo.

Doctor's Best, Suntheanine L-Theanine, 150 mg, 90 Veggie Caps (

Posted by Reviewer1286157 on May 17, 2010

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

Very Good Buy

This is an excellent product for a very good price. I notice I am calmer and sleeping better after one week of taking this patented l-theanine formula.

Seems to work pretty well

Posted by Reviewer1990660 on Mar 05, 2010

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.

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

DB's Suntheanine

Posted by Reviewer2328138 on Jul 12, 2010

I like it! You can sense the uptake in about 30 minutes! Amazing. Very relaxing. Works for about 6 hours. I would recommend taking it after strenuous exercise as it might be too relaxing!

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.
