Suntheanine

Promotes Relaxation and Learning Ability

Dietary Supplement

 Theanine 200 is a unique amino acid found almost exclusively in green tea that exerts beneficial effects on brain metabolism. Theanine induces relaxation without causing drowsiness, as measured by increased generation of alpha-waves. Theanine may improve learning ability and sensations of pleasure by affecting dopamine and serotonin neurotransmitters in the brain. Also, Theanine exerts protective effects on the brain by mitigating glutamate toxicity.

 Jarrow Formulas Theanine is made enzymatically from amino acids and is identical to the theanine found in green tea.

 Suggested Use

 Take 1 capsule per day with water or juice on an empty stomach or as directed by your qualified healthcare professional.

Theanine For Anxiety

From California

Great results using theanine to control anxiety. I am no longer dependent on Xanax. Something so simple and natural has changed my life for the better. I highly recommend this product.

Calmness and improved focus

From Colorado

I have been using this product for 3 months now, and I can say that I see improvement in my mental focus and clarity. I used it at a time when all other things stayed the same, so I could gauge the effect of the theanine. I am ordering more now, and adding to my permanent supplement intake. I hope others find that it works for them equally well!

Theanine

 

What Is L-theanine?

 

Jarrow FormulasTheanine supplies an efficacious source of the rare amino acid L-theanine (chemical name gamma-ethylamino-Lglutamic acid). This amino acid is found only in certain species of tea plants. It constitutes 1-2% of the dry weight of tea leaves and accounts for about 50% of the free amino acids present in the leaves. First discovered in 1949, L-theanine not only is an important healthgiving constituent of tea, but also is the major flavor component of green tea.

 

The Relaxation Factor

 

Curiously, despite its caffeine content, certain teas tends to relax people without making them drowsy.  Those engaging in meditation may drink tea to dispel mental sluggishness without becoming agitated, as is typical with excess coffee consumption.  L-Theanine appears to be the component in green tea responsible for these benefits.  This is good news for the 65% of American adults who suffer from daily stress.

The anti-stress effects of L-theanine have been documented repeatedly. In several trials, researchers examined brain wave patterns after theanine ingestion.* Humans produce four specific patterns of electrical pulses, namely alpha, beta, delta and theta waves, which mirror brain states.  The four patterns of brain activity represent relaxed wakefulness, excitation, sound sleep, and dozing sleep, respectively.

F O R M U L A S

 

In one experiment, 50 young female volunteers were divided into high-anxiety and low-anxiety groups. Each group was given 50-200 mg theanine in water once a week.  Their brain waves were measured during the 60 minutes after ingestion. Measurements were repeated twice during a two-month test period. The results showed a marked increase in alpha waves starting roughly 40 minutes after ingestion. Researchers concluded that theanine rapidly enters the system when ingested, and heightens the brain wave linked to relaxed wakefulness.* With regard to anxiety level in test subjects, those manifesting high anxiety showed a greater degree of brain wave change towards alpha.*

This calming effect also translated to a significant alleviation of PMS symptoms. Women taking 200 mg L-theanine daily were shown to have a lower incidence of physical, mental, and social symptoms.*

 

Improved Learning

 

Animal studies were employed to determine if theanine exerts an impact upon memory and learning ability.  In one memory experiment based upon learned avoidance, the theanine-treated animals were more successful than controls, and their advantage increased proportionally with the number of tests.  In another test, which measured learning ability, theanine-treated animals out-performed controls, especially as the tests became more advanced.

Theanine achieves its benefits in the areas of relaxation and learning by affecting brain neurotransmitters.* As a building block for the inhibitory neurotransmitter Gamma Amino Butyric Acid (GABA), theanine influences the release of two other neurotransmitters, dopamine and serotonin. Dopamine has many functions in the brain involving motor functions and general arousal. Temporary elevation of dopamine levels often leads to improved mood, alertness, libido, verbal fluency and creativity. Serotonin, another feel-good brain signal, plays an important role in regulating mood, emotion, sleep and appetite. Serotonin is also involved in learning, memory and other cognitive processes. Deficiency is associated with low mood, lack of will power, and poor appetite control.

 

Benefits for the Liver and Nerve Health

 

Another animal trial with theanine looked at its effects upon liver health, using a known liver toxin, D-galactosamine.  Theanine was shown to be active in preventing injury to the liver, whereas glutamine in equal amounts showed no protective effect.*  Studies using other models of liver injury also have demonstrated benefits. Recent research suggests that serotonin plays an important role in liver regeneration and acts as a mitogen (induces cell division) throughout the body.

 

Furthermore, theanine appears to protect against certain excitotoxins.  For example, it reduces stimulation associated with caffeine, and inhibits some activities of norepinephrine in the central nervous system.* In gerbils, theanine protected against ischemic delayed neuronal death, a condition where a rapid increase in glutamate results in nerve cell death.*
