Green Tea Extract Brief Introduction:
Green tea originates in China and has become associated with many cultures throughout Asia. It has recently become more widespread in the west, where black tea is traditionally consumed. Many varieties of green tea have been created in countries where they are grown. These varieties can differ substantially due to variable growing conditions, horticulture, production processing, and harvesting time.
Regular green tea drinkers may have a lower risk of developing heart disease and certain types of cancer.
Tea polyphenols is a natural polyphenol compound extracted from green tea. Its main component is catechins. It has an outstanding effect on antioxidant and scavenging activated free radicals. It is regarded to be good to the heath,cosmetics, longevity and cancer prevention of people. Green tea extract is choice raw materials for food, cosmetics,health products and drugs.
Polyphenols, flavonoids, catechins and EGCG are powerful antioxidants that appear to interfere with and reduce the spread of certain types of cancer cells.
There is no additives, no preservatives, no artificial colors in our Green Tea Extract.
The active ingredients in green tea extract are polyphenols in the form of flavonoids like catechins and epigallocatechin gallate (EGCG).
The antioxidant activity of EGCG in green tea extract is purportedly up to 100 times more powerful than that of vitamin C or E. They provide beneficial health effects by protecting the body from the damaging effects of oxidative damage from free radicals.
