Product review of L-Theanine

Posted by Reviewer2702612 on Jan 23, 2007

I have tried various competitors products, but find Natural Factors L-Theanine to be the most effective. I feel that it is a good "clean" product.

Great for raising Alpha levels

This product was a life saver in helping my son get off drugs (particularly downers like alcohol, heroin and pot). These plus neurofeedback therapy and, so far, great success!

Calms, improves mood

Posted by 4points on Sep 23, 2009

Works just like the product information I read recently. Taken in evening a while before bed it helps to settle down and end the day on time.

It Works for Me - Very Good Supplement

Posted by DemureAngel on Mar 05, 2014

I read Dr. Murray's free book on Stress, Anxiety and Insomnia so I decided to try this product. I take this supplement along with Pharma GABA and it has been really helpful. I am satisfied with the effects it had on me; it was almost immediate. If you are unsure whether this is right for you, read Dr. Murray's book. It's got important information you need to know first.
