Calms the Anxiety

Posted by Reviewer1289596 on Jun 27, 2008

My doctor prescribed this product for me after my Neurotransmitter test show problems with my them being very high causing anxiety, irritability, etc. This product worked like charm. It's like all the rough nerves got smooth down. I feel more calm and sleep deeper.

I only use this PRN, that is, as needed during the night if I should wake up and not be able to fall back right away. Or if I am particularly anxious, this is wonderful. It helps me sleep restoratively, yet without any drowsiness when I awake.

I use this product as a sleep aid and it works quite well. The i-herb price is much better than any retail store

My son has ADHD which his doctors have been unable to treat. I heard about L-Theanine from a friend and we've been taking it. It doesn't "cure" his hyperactivity, but it does take the edge off and make it "less squirmy in his seat," his teacher told me.

Sleeping assistant

Posted by Reviewer2404464 on Feb 16, 2009

I ordered L-Theanine as recommemdation of the friend to make my sleep better. I can stay that I am a little bit less nervous person in general. I also can say that I manage to sleep a little bit longer than I used to and fall asleep right after I woke up in the middle of the nigt. However, I can't say that this worked miracles for me. I will try it for another month.
