I liked this product at first and how relaxed I felt, but I had increased thoughts of voilence and suicide. I stopped taking it and now I'm back to normal. It works the same way that anti-anxieties work, and many of those medications can increase thoughts of suicide. Also, be careful if you take epilepsy medication as it can interfere with that. I started having more petite maul seizures. Plus I had a hard time remembering things. I've decided to stick with my Blue Vervain for now. I'm sure this can work on others, but I highly recommend that you stop taking it if you have any of the above symptoms that I experienced :/

L-Theanine is a relaxing but non-sedating amino acid. This product by Now Foods featuring Suntheanine which is an award-winning patented brand of L-Theanine from Japan. I like this great product a lot. It’s like yoga in a bottle because it helps to bring me back into balance with my nervous systems. Unlike other stress reducing supplements, Suntheanine does not cause drowsiness. Suntheanine brings a state of clarity into my day which can help me make better life decisions. I highly recommend this high quality product. I am a strong advocate on scientific medical research and evidence-based information, and constantly want to differentiate between marketing hyperbole and real world effects. I hope you'll find my review Helpful to you. Best wishes and good health to everyone!
Best product against insomnia

This is the best natural product against insomnia I've ever had. I wake up a bit sleepy, but that effect disappears after taking a shower. The relaxing effect works through the day after: it makes the mind less messy, more focused. Definitely a keeper.
Great for anxiety...check for time to take

Both this upon several friends recommendations. Had been taking l-tyrosine and really liked it also. With the l-theanine I find that you have to decide what time is better in the day to take it. I was first taking it in the morning and it left me too letargic..probably overrelaxed which is great for the wknds but not so great when you have kids to teach. I found that taking it at night(several hours before I went to bed) has been what works for me so that I am feeling relaxed yet not tired. Great to take the edge off your mood and level off anxiety. Great suplement!

I take this about 1-1/2 hours before bed. I'm still having trouble with initial insomnia but once I get to sleep, man, is it a good sleep! I have great dreams, not creepy ones like on melatonin. A pretty calming product, will buy again. Shipping superfast and perfect as always.
