L-Theanine – Nature’s Relaxation Supplement*
From green tea to black tea to Earl Grey, most of us have tasted the unique flavor that tea leaves can impart. What you may not know is that tea leaves also contain a unique amino acid called L-theanine. This amino acid promotes relaxation while maintaining alertness and supports healthy cognitive function.* L-theanine may also support healthy vascular function through this relaxing effect.* Letstake a closer look at this amazing amino acid and how it can benefit your health.
How L-Theanine Works
L-theanine is structurally similar to glutamic acid, which is a neurotransmitter involved in cerebral cortex activation.* The brainstem is responsible for controlling heart rate and blood pressure. When the brainstem senses stress, it signals the adrenal glands to release cortisol, which results in an increase in heart rate and blood pressure. L-theanine has been shown to directly inhibit the binding of corticosterone to receptors in the brainstem, thereby promoting relaxation without causing drowsiness.*
L-theanine also crosses the blood-brain barrier and increases levels of GABA (gamma aminobutyric acid), serotonin, and dopamine in the brain.* GABA is a neurotransmitter that has a calming effect on the nervous system.* serotonin is a neurotransmitter involved in regulating mood, appetite, and sleep.* dopamine is a neurotransmitter involved in motor control and motivation.* By increasing levels of these neurotransmitters, L-theanine promotes relaxation while maintaining alertness.*
Health Benefits of L-Theanine
In addition to promoting relaxation while maintaining alertness, L-theanine has also been shown to support healthy cognitive function.* One study found that L-theanine improved reaction time during task switching and enhanced accuracy during attention switching tasks in young adults.* Another study showed that L-theanine improved performance on cognitively demanding tasks as well as subjective measures of “alertness, calmness, and contentedness” in healthy adults with mild cognitive impairment.*
L-theanine may also support healthy vascular function through its relaxing effect on smooth muscle tissue.* One study showed that L-theanine significantly reduced total cholesterol and low density lipoprotein (LDL) cholesterol in rats fed a high cholesterol diet for 12 weeks.* Another study showed that L-theanine increased cerebral blood flow velocity in healthy young adults with no history of hypertension.*
If you’re looking for a natural way to promote relaxation while maintaining alertness, look no further than L-theanine. This unique amino acid found naturally in tea leaves has been shown to support healthy cognitive function and vascular function through its relaxing effect on smooth muscle tissue. *So next time you’re feeling stressed out, try brewing up a cup of tea – your body will thank you!*
