What a difference

Posted by Reviewer1696377 on Dec 08, 2008

Wow ! This seems to be making a big difference for me. What a relief. I have spent several years on antidepressants and I really don't want to keep doing that. I really do feel more calm.

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).

Very effective against insomnia

Posted by Reviewer1728405 on Apr 23, 2009

Source Natural's L-Theanine works well for insomnia caused by an over active mind. It makes the mind quiet, without any side effects.

I use L-Theanine, along with 3 mg of Melatonin at bedtime, and find that I sleep more restfully. Unlike drugstore sleep-aids, I never feel "drugged," either after taking it or upon waking.

My husband and I bought this for our son who suffers from ADD. It seems to be working much better than the Puritan Pride brand. In doing our research Source Natural seems to be one of the better brand names. Good stuff! Keep up the good work. J & T of Florida

good for sleep

Posted by Reviewer2411275 on May 20, 2009

I purchased this for my 10 year old with autism and his sleep issues. This really helps him fall asleep and stay asleep better than melatonin.

L-Theanine Help

Posted by Reviewer1481204 on Aug 27, 2008

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

didn't do much at all.

Posted by Reviewer2681091 on Jan 27, 2008

Not sure what this did to be honest, as I noticed much more significant results using 5HTP.

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!
