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.
