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.
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.
