L-Theanine - 60 Capsules

by Integrative Therapeutics

5.0 star rating 1 Review


Integrative Therapeutics L-Theanine

L-theanine is an amino acid that helps promote a restful, relaxed state without diminishing daytime alertness. It's free of the side effects commonly associated with other relaxing agents and can be used to aid in stress management.

During a study of human volunteers, L-theanine promoted the generation of alpha brain waves, an indication of relaxation. Another small, controlled clinical trial suggests that L-theanine supports a healthy stress response. Results of yet another human trial suggest that L-theanine may act via the sympathetic-medullary system, either in addition to or instead of the hypothalamic-pituitary-adrenal axis. L-theanine has long thought to interact with the binding of L-glutamic acid to glutamate receptors in the brain.

L-Theanine (Suntheanine® brand)   -   100 mg
