Calms your mind and makes you focus better. Reduces anxiety and helps you step away from overwhelming situations to resolve them better. Also helps when taking with Doctor's Best L-Tryptophan for sleeping. As this product works on a brain level (got this from the great nutritionists at Doctor's Best), it helps calm the brain and the L-Tryptophan helps on the hormonal level. Best sleep i've ever gotten and all night too. I have put my entire office on the Doctor's Best Suntheanine L-Theanine product. As a manager i have found people are more productive and much better to get along with. Also my husband kids and mother love this product. Doctor's Best does have the best product by far. By the way, I always get experts to talk to when I need any questions answered. My kind of company. Angie.
I have been taking L-Theanine for several years now. I initially took it only when I felt increased stress. As my anxiety got worse, I have found that if I take it both in the morning, and before bed, my anxiety rarely gets away from me. It has helped to bring more balance to my life.
A great product for stress

Seems to lower appetite

I've used it for a while, and there were some interesting effects, but they were one-off. One thing that seems to persist is that I'm less hungry, when I take it.

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!
Helps with sleep

Theanine with Tryptophan helps with sleep on the occasional nights when I'm awake in the middle of the night.

I didn't expect this product to help me sleep-- more just for general relaxation-- but it really does. I have found it particularly useful for insomnia related to stress, anxiety, etc. A very handy product to have around for such times. Recommended.
