iHerb Customer Reviews
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.
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.
Using for Calmness and Sleep

I used to have anxiety dreams, the nonsense kind that keep reeling around my head during sleep. I find that this helps stop those anxious revolving thoughts. Will keep using.

Para mi resulta imprescindible y siempre lo tengo a mano, me calma cuando estoy nerviosa sin dejarme "atontada" o con sueño, sin efectos secundarios ni crear adicción (puedo usarlo temporadas y dejarlo otras, sin problema) Seguiré comprando y siempre de Dr Best que es una de mis marcas favoritas para suplementos
