Green Tea Extract

The Chinese have used green tea for thousands of years. Green tea is also widely consumed in Japan, China and other Asian Nations and is becoming more popular in Western Nations either in a form of water or green tea extract.

A number of beneficial effects are attributed to regular consumption of green tea and green tea extracts.



The Powerful antioxidant, polyphenols in green tea extract can help protect against cell damage and also a compound which could interface with the development of new blood vessels, which tumours need to grow.
Green Tea Extract Catechins, compounds in green tea extract are 25-100 times stronger than vitamin C and E. They protect the body from damage effects of oxidative damage from free radicals.

Considerable epidemiological and experimental evidence shows beneficial effects of green tea extract in reducing the risk of heart disease and cancer, most likely due to the antioxidant property of polyphenols.

As many researches reported, EGCG (epigallocatechin-3-gallate),Green Tea Extract ,one of key elements in green tea extract will block production of an enzyme required for cancer cell growth. EGCG may work by suppressing the formation of blood vessels, a process called angiogenesis, thereby cutting off the supply of blood to cancer cells.

Herbalists use green tea and extracts of its leaves for stomach problems, vomiting, and diarrhea, and to reduce tooth decay, blood pressure and cholesterol levels.

Recommended Dosage of Green Tea Extracts

So for those who want all of these health benefits but are daunted by prospect of fitting 4 to 10 cups of green tea into their daily routine, Green Tea Extract solves the problem by supplying the key tea polyphenols in a highly concentrated formulation.

A typical dosage is 125 - 500 mg/day - preferably of and extract standardized to at least 60% polyphenols and/or EGCG as a marker compound in green tea extract (This should be equivalent to 4-10 cups of brewed green tea).

Excessive caffeine is not a significant problem, because green tea extract contains only a fraction of what is found in coffee.

Considering the wide safety margin of green tea extract and the fact that benefits have been documented at over 10 cups of tea per day, we recommend taking 1 to 5 capsules spread out throughout the day.

The Second Well-Known Beverage, Green Tea

Green tea is the second most consumed beverage in the world (water is the first) and has been used medicinally for centuries in China and Japan. That is because a number of beneficial health effects in green tea are attributed to regular consumption of green tea and dried/powdered extracts of green tea.

Tea time: The Wonderful Benefits in Green tea

The health benefits of green tea beverage have been discovered. In total world consumption of tea, green tea makes up about 20% of the total. In China, on the other hand, green tea is the most popular.


Green tea is rich in antioxidants.
Benefit of drinking a cup of green tea might do more than warm you up this winter. Researchers offer even more reasons to make time for this age-old beverage. The tea leaves used for making tea are the same plant but the processing each type of teas is different.

Green tea comes from the leaves of the white-flowered tea plant, Camellia sinensis, a bush native to Asia. These tea leaves are less processed than black tea and contain rich sources of antioxidants, which protect the body's cells from damage and fight diseases. The antioxidants, the benefits in green tea have been linked to cancer prevention, decreased risk of stroke, heart diseases, and lowered blood cholesterol. Catechin, a phytochemical, is the main component which benefits in green tea and is present in higher amounts than in grape juice and red wine, which are also believed to reduce the rate of heart disease. Other health benefits of green tea are still plenty!

Good for your heart?

Recent research suggests that beneficial antioxidants in green tea play a role in reducing the negative effects of bad cholesterol, lowering triglyceride levels and increasing the production of good cholesterol. They have also been shown to inhibit excessive blood clotting which may help against heart diseases and stroke. Further evidence has suggested that green tea plays a role in prevention of age-related and brain degeneration diseases, such as Parkinson and Alzheimer's. Its antioxidant properties are thought to reduce free radical damage and the breakdown of neurotransmitters. That is another beneficial antioxidants of green tea for health.

Cancer prevention?

Green tea's rich supply of antioxidants may also play a key role in the prevention of various cancers, like breast, colon, stomach, and lung cancer. They suppress the formation and growth of potent cancer-causing agents. While the potential anti-cancer properties of green tea look promising, they are also complex and not yet completely understood.

Good for your teeth?

Another interesting benefit of green tea is its effectiveness in preventing dental decay. It inhibits the growth of oral bacteria, which can help to fight cavities. When used as a mouth rinse, green tea reduced plaque and the incident of periodontal disease.

How to serve green tea

You can enjoy green tea including its numerous health benefits during any season. Green tea can be served hot or cold and still provide a host of health benefits. While sugar and lemon are not thought to alter the antioxidant content, milk may bind to the antioxidants and make them unavailable to the body. To brew a potent cup of green tea, make sure to steep the tea bag for at least 3 minutes. Otherwise, all of the antioxidants may not end up in the tea. If you're concerned about caffeine, a 6-ounce cup of green tea contains approximately 30 mg. That is much lower than coffee, which has about 100 mg per cup.

While there is plenty of new and exciting evidence about the health benefits of green tea, it's still important to eat a well-balanced diet that includes other rich sources of antioxidants, like fruits and vegetables.
