Great Value

Posted by Reviewer3099724 on Oct 25, 2008

Works great to keep mood swings in check. Also a great value compared to other brands. It is 100% L Theanine (No D-Theanine).

This product, along with 5-HTP (which I take at night) has really helped me.

Takes the edge off

Posted by Reviewer2052996 on Jan 15, 2008

I have a somewhat stressful job and I find that the Source Naturals L-Theanine takes the edge off and leaves me alert, but calm, which is exactly what I need!

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

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.

Source Naturals, L-Theanine, 200 mg, 60 Capsules (

Posted by Reviewer1971676 on Jun 27, 2008

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 was really glad to find an alternative to Prescription medication. It works great.
