Very good product at a great price. At 150mg it is a perfect quantity for me to take morning and night. Im sleeping better, calm and relaxed during the day and with great focus and attention.
Excellent product for relaxation

Noticeably reduces the irritating effects of caffeine.

I recently removed the 5-HTP from my supplement line-up because I was exhibiting signs of too much serotonin. L-Theanine is a precursor to other neurotransmitters and seems to be useful and have a balancing effect, especially for those of us with fibromyalgia.

I started with 150mg at bedtime, and found it lowers my morning fasting blood sugar! I did not expect this, but discovered it while I was testing frequently. This may be due to the comments I see on the net that theanine can lower cortisol...which is considered a factor in some "dawn phenomenon" patients with insulin resistance/type II diabetes. I don't know if this is really the explanation, but it certainly lowered my morning fasting glucose readings by 30pts or more! During the course of this bottle which is a 90 ct size, our home has had a major stressor, and grief generator, and I have been very upset during this time. So last night I took 300mg instead of the usual 150mg. I slept more soundly, and awakened with a less "heavy heart"...which is what I call my anxiety grief reaction to the acute/temporary stress here. If I feel the return of this anxiety today, I'll take 150mg in the daytime, and another 300mg at bedtime. I am very pleased with this product for myself. But I do think people may vary in their responses. And I think perhaps a higher dose may work for those that are not satisfied with 150mg a day. . . . You can find other products I use on my Page!

I really like this product. It has enabled me to delete a similar perscription product from my daily routine and take this on an as needed basis. Cheaper and better for me.

I feel this is the best deal for the quantity and strength. I take it at night as it helps me sleep really well. I used to not be able to shut off my brain at night but this calms me down and sleep quite well. Sometimes I take it during the day but take Gaba more during the day then theanine.

I started taking this instead of St. John's Wart which always helped me with mild anxiety. This seems to work just as well.

It took away the anxiety but I had no energy.
