Description:
L-Theanine (gamma-glutamylethylamide) is an analog of glutamate and glutamine that is capable of crossing the blood-brain barrier. It is a form of L-Glutamic acid which is able to help increase and modulate alpha brain waves. These brain waves help to produce a feeling of calm, relaxed alertness.
A Host of Health-Enhancing Benefits
Research shows that L-theanine has numerous health-enhancing effects, including promoting healthy cognitive function. In studies of neurons in cell culture, L-theanine reversed glutamate- or other neurotoxicant-induced neurotoxicity, a major cause of normal brain aging.19-30
Beware of Imitations: The L-theanine used in Natural Stress Relief is Suntheanine®, the only pure form of L-theanine protected by 40 internationally recognized patents and scientifically proven in clinical studies to be safe and efficacious. Independent laboratory analysis has verified that certain other products on the market claiming to contain “L-theanine” are only half L-theanine, the other half being a different form of theanine known as “D-theanine” which has not been scientifically evaluated in published studies.
