Another benefit of green tea it’s is lower in caffeine than most other teas, so you may be able to drink the five cups a day that lowered psychological stress in a large group of Japanese people in a recent study done at Sendai’s Tohoku University Graduate School of Medicine. The researchers didn’t identify any particular component of green tea that might have been soothing, but animal studies suggest that one compound, EGCC, had both sedative and hypnotic effects that tamp down the body’s production of stress chemicals.
facilitates the burning of body fat. Green tea promotes the body’s ability to burn fat through thermogenesis and fat oxidation. A study published in The American Journal of Clinical Nutrition found the combination of polyphenols and caffeine from an extract of green tea resulted in a “significant increase” of energy expenditure compared to placebo.

Green tea also seems to boost physical performance, increase exercise endurance, and decrease reaction time, and there are many, many such studies showing these effects from caffeine, although other ingredients in green tea may aid this effect. Caffeine, and green tea’s, ability to mobilize fatty acids in fat tissue to make them more easily available for use as energy also seems to aid physical performance. In one study, caffeine was shown to significantly increase physical performance (exercise endurance and exertion). The antioxidants in green tea may also help prevent tissue damage during physical exertion as well.

Green tea has many health benefits. “It contains many nutrients, including antioxidants and anti-cancer and brain-healthy compounds,” Smith reminds us. One thing is for sure: regardless of whether or not you’ll shed pounds with green tea, drink it anyway. “All teas contain many healthful nutrients; it’s one of the healthier choices for a beverage!” Smith says.
According to science, matcha is something of a miracle supplement. For one, it makes you feel good. One recent study examined the effects of the phytochemicals in green tea on mood and cognition. The combo of caffeine (present in most green teas) and L-theanine, an amino acid found in some teas, were found to “improve performance in attention-switching tasks and alertness, but to a lesser extent than caffeine alone,” partly because of how L-theanine chills you out.
I ordered this product after many phenomenal reviews about it, and its miraculous properties to aid in your weight loss efforts. After having it used for several weeks in a row and following a healthy diet and exercise plan, I have not seen any changes in my weight, or any benefits from this tea. Unfortunately this does not mean that it would not work for you, as every human physiology is quite different. The one positive about this tea that I can give is that it has a quite pleasing taste.
In 2009, King’s College researchers found that epicatechin may protect brain cells through mechanisms unrelated to its antioxidant ability, as epicatechin is one of the few flavonoids that can cross the blood-brain barrier. The King’s College researchers reported that somehow epicatechin protects brain cells from the negative effects of beta-amyloid plaques, although the exact mechanism of how this works is still not entirely know.

"Tea is a good source of compounds known as catechins and epicatechins, which are thought to be responsible for tea's beneficial health effects," says Dr. Howard Sesso, associate professor of medicine at Harvard Medical School and associate epidemiologist at Brigham and Women's Hospital. These compounds belong to a group of plant chemicals called flavonoids. Research suggests that flavonoids help quell inflammation, and that in turn may reduce plaque buildup inside arteries. Green tea has slightly higher amounts of these chemicals than black tea. Both black and green teas also contain modest amounts of caffeine, ranging from about 20 to 45 milligrams per 8-ounce cup. That's roughly half the amount of caffeine in the same amount of coffee.
