iHerb Customer Reviews

Couple with caffeine.

Take this if you like caffeinated drinks, but can't handle the caffeine. As a combination, you can really achieve a lot in the day.

Great for insomnia. But it did not help me for my anxiety.

I've been using this for more than two weeks now, and I can honestly say there's a difference. I can feel it. I take one capsule an hour (more or less) before going to bed, plus I drink a good cup of Hops flower tea (also from iherb). At first I experienced a big positive change in my sleeping cycle and sleep quality. My dreams became much more lucid and my sleep became very hard, after the first week I started getting used to that, in a good way. The most important part is that during the days, after I started consuming L-Theanine, my panic levels went a down. The stress doesn't fade away completely, but become a bit translucent, and then easier to cope with. This is not a magic cure or anything, it won't make you panic-less. I suffer from a very harsh panic disorder and to have a day or two without a panic attack is blessed. And that is what I have achieved by using L-Theanine. One last thing, at the first week I also had a few stomach issues, I'm not saying it's necessarily related, since I had other dietary issues back then.
