good product

Posted by Reviewer2154310 on Jan 30, 2013

helped my husband to get rid of sleeping pills. Also my sleep problems solved with this product last fall. 3 capsules in empty stomach and we got peaceful sleep.

Works quite well for mild anxiety and stress. I take L-Theanine occasionally, usually after lunch at work and it seems to help me focus better.

Not as good as Source Naturals

Posted by Reviewer2814550 on Feb 17, 2010

This one didn't work as well for me as the 200mg Source Naturals brand. The 200mg first thing in the morning on an empty stomach has worked wonders for my anxiety and helped me get off ativan.

Works Well

Posted by Reviewer1799903 on Jan 04, 2011

Works well for mild to moderate anxiety and stress. Does not make me drowsy. Not super-strong, but it does have a mild calming effect that helps noticeably. Worth trying if you have anxiety issues.

Wonderful and immediate results!

Posted by Reviewer2091864 on Apr 22, 2011

I had been having a 'tight' chest on and off for three months, my blood pressure was elevated, and I was having difficulty sleeping well. About 10 days after beginning Suntheanine,1 capsule/day, I woke up feeling immensely better. I would classify this as a Wonder Supplement!

Really good L-Theanine. Take two and you really notice the calming effect. Good to take before bed, or whren you've had too much caffiene!

Unobtrusively improves mood and ability to handle stress, feels natural - no sensation of being medicated.

Works great for anxiety

Posted by Reviewer1495755 on Jun 08, 2010

This does work really well for my anxiety, however, next time I will purchase the chewables (by another brand) as it takes approx. 15-20 minutes for these to kick in. Also, when I take more than 1 a day I do tend to feel a bit drowsy which I don't like (but often my anxiety returns later in the afternoon and I feel I need to take another one). Otherwise, these are very effective. I am a fan of Doctor's Best products because of their quality and I love I-herb's prices. :)

Anxiety/Panic Attacks from Anti-Seizure Medication

Posted by Reviewer1364576 on Nov 24, 2009

I saw this recommended on epilepsy.com so I decided to try it. My neurologist wanted to put me on Zoloft. I've been only taking one cap daily & it seems to help. I'm much calming during the day & sleep well at night. I would recommend this natural alternative.

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.
