Jarrow Formulas Theanine 100mg is a unique amino acid found almost exclusively in green tea with 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 has protective effects on the brain by antagonizing glutamate toxicity. This way it also improves quality of sleep, mood, heightens mental acuity and reduces negative side-effects of caffeine.

who can benefit from Theanine?
People with daily stress use this product largely to relaxo, or to improve sleep. It can also be used to help improve focus, promote liver health or counteract stimulants.

what distinguishes Theanine?
• each caspule provides the equivalent of 2-3 cups of tea
• enzymatically produced  SunTheanine which is identical to the theanine in green tea

how does each active ingredient function in Theanine?
• L-Theanine is a precursor for the production of neurotransmitters that serve health in numerous ways. It is especially useful as a relaxant without drowsiness.

Theanine is a rare amino acid  (chemical name gamma-ethylamino-L-glutamic acid) and 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 health-giving 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.

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

Skin hunger: why we crave touch

As we are in the midst of the Easter Holiday, we can't help but feel sad. While Mother Nature is showing abundant signs of spring during a period of incredibly sunny weather, we are barely allowed to go outside other than to do what is absolutely necessary. Our gyms have been closed for almost a month now while in some countries, people aren't even allowed to exercise. Not just group exercise, but also to just jump on a bike and go for long rides. 

While couples and families get grumpy from living together in a cramped space, others face different problems: they are living without any companion whatsoever. Therefore it's not a miracle how all of a sudden, pet asylums have been able to 'clear out' their list of unwanted pets. Not just because people have more time at hand to walk a dog (just about the only thing some are allowed to do) but also because they crave the ability to touch a living being, for lack of being able to touch another human.

Somehow, just like the sense of smell is overlooked, this also is true for the sense of touch. Only when we lose it, we crave it. This craving also is called 'touch hunger' or 'skin hunger'.

Declutter your life and feel liberated!

Sounds familiar, huh?
