Green Tea Extract

Green tea has been traced as far back as over 4000 years ago in China. The medicinal properties of tea have been given serious scientific support. Studies have shown that drinking four cups of green tea a day can reduce the risk of developing stomach and lung cancer as well as heart disease. Green tea contains the cancer-fighting flavonoid ECGC, which is unique in that it seems to fight cancer at all stages, from chemical carcinogens, to suppressing the spread of tumors. Flavonoids are most commonly known for their antioxidant activity. The chemical components in green tea are 100 times more powerful an antioxidant as Vitamin C, and 25 times more powerful than Vitamin E.

Did you know that green tea can even help prevent tooth decay? Just as its bacteria-destroying abilities can help prevent food poisoning, it can also kill the bacteria, which causes dental plaque. Green tea antioxidants have been shown to have a direct effect on lowering cholesterol levels as well. Green tea also causes carbohydrates to be released slowly, preventing sharp increases in blood-insulin levels. This promotes the burning of fat. Many scientists believe there is a connection between all of the components of green tea; and these combined properties account for its health-enhancing properties. Unfermented green tea leaves, by the way, are the most natural way to gain these benefits.

Green tea extract can be purchased in any health food store, supermarket or pharmacy. It is available in several forms including: tablets, powder, capsules, liquid, and as a tea. Capsule forms are known to contain the most antioxidants. Consumers interested in green tea extract benefits, should look for tea products that are the freshest possible, as well as sealed in an airtight container, as green tea does not have a long shelf life.

Green tea extract contains caffeine, which has been known to contribute to problems sleeping when taken before bedtime, as well as irritability, dizziness, vomiting, headache, loss of appetite, diarrhea, and possible irregular heartbeat in rare cases.
