Info: 60 Veg. Capsules
Originally found in green tea (in relatively small doses), L-Theanine is a unique type of amino acid which turns out to be a biologically active compound capable of promoting relaxation without inducing drowsiness and improving concentration and learning ability during the day, and also promoting a more restful sleep at night. It acts by regulating neurotransmitter activity in the brain and decreasing cortisol levels in the face of stress.

Product Notes:
