Had high hopes that this supplement could take the edge off at night, but after 2 weeks varying the dose from one cap to six i felt none of the marketed effects.

Thanks for your feedback!

have not noticed any changes

Have not really noticed any difference in anxiety or stress during the day. I might start supplementing at night.

Thanks for your feedback!

Not sure how to rate

Posted by iHerb Customer on September 3 2015 | Verified Purchase

This product works...almost immediately but there is a catch! I felt woozy and tired for the whole day. It actually made me sleepy and "heavy-headed". I couldn't concentrate at work but took it for 2 more days in order to find out the culprit. Needless to say that was a bad decision! I was fatigue the entire week and it actually took me a while to recover. I hated the feeling after taking suntheanine, it felt like someone was controlling my brain. Advice: Take this only when you are very very very very anxious.

Thanks for your feedback!

Not for me

I bought this product as I heard it was meant to help with anxiety and sleep, however it made matters worse. Found it difficult to sleep and became very jittery. It might work for people who do not have such severe anxiety.

Thanks for your feedback!
