Background:

 

Green tea extract is a bioflavonoid rich, potent extract used primarily for fighting free radicals. It contains a high content of polyphenols, which are a class of bioflavonoids. Green tea extract contains a potent antioxidant, EGCG, which is over 200 times more powerful than vitamin E in neutralizing the pro-oxidants and free radicals that attack lipids in the brain. This important ingredient, Epigallocatechin Gallate (EGCG), protects against digestive and respiratory infections, helps to block the cancer promoting actions of carcinogens, protects against high total and LDL cholesterol levels, and blocks the attachment of the bacteria associated with dental cavities to the teeth.
Green tea extract helps with thermogenesis and aids in the metabolism of fat. Known for years as a powerful antioxidant, it may also be helpful in shedding fat. The most obvious benefit to dieters is that it works without increasing the heart rate most often found in diet aids. The increased heart rate leaves dieters jittery and eventually, most dieters stop using the supplement and gain weight back. Now through using green tea extract, dieters get the weight loss benefits without any of the jittery effects, especially in obese individuals with hypertension and other cardiovascular complications.

Study about l-theanine
While structurally related to the excitatory neurotransmitter glutamate, theanine only has weak affinity for the glutamate receptor on postsynaptic cells. Rather, its primary effect seems to increase the overall level of the brain inhibitory transmitter GABA. Theanine also increases brain dopamine levels and has a low affinity for AMPA, kainate and NMDA receptors. Its effect on serotonin is still a matter of debate in the scientific community, with studies showing increases and decreases in brain serotonin levels using similar experimental protocols. It has also been found that injecting spontaneously hypertensive mice with theanine significantly lowered levels of 5-hydroxyindoles in the brain. Researchers also speculate it may inhibit glutamic acid excitotoxicity. Theanine also promotes alpha wave production in the brain.
Studies on test rats have shown even repeated, extremely high doses of theanine cause little to no harmful psychological or physical effects. Theanine showed neuroprotective effects in one rat study.
A placebo-controlled trial has shown adding theanine to ongoing antipsychotic medication is helpful in reducing some symptoms of schizophrenia.
Several beverage manufacturers are selling drinks containing theanine and are marketing them as drinks to help people focus and concentrate, while other manufacturers claim relaxing and tranquillizing properties.
Immune system benefits
L-Theanine may help the body's immune response to infection by boosting the disease-fighting capacity of gamma delta T cells. The study, published in 2003 by the Brigham and Women's Hospital, included a four-week trial with 11 coffee drinkers and 10 tea drinkers, who consumed 600 milliliters of coffee or black tea daily. Blood sample analysis found the production of antibacterial proteins was up to five times higher in the tea drinkers, an indicator of a stronger immune response.
As a supplement
In 2003, the German Federal Institute for Risk Assessment (Bundesinstitut für Risikobewertung, BfR) objected to the addition of isolated theanine to beverages. The institute stated the amount of theanine consumed by regular drinkers of tea or coffee is virtually impossible to determine. While it was estimated the quantity of green tea consumed by the average Japanese tea drinker per day contains about 20 mg of the substance, there are no studies measuring the amount of theanine being extracted by typical preparation methods, or the percentage lost by discarding the first infusion.
