Helps with sleep

Posted by 5206100159286206775 on May 25, 2016

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

effective stuff

Posted by 5355254441692460143 on May 19, 2016

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

Posted by Reviewer2329814 on May 11, 2016

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
