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.

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).

good for sleep

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.

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

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.
