Green Tea, 95% Polyphenal Extract

Green tea and its health benefits in the spotlight.

Scientifically reviewed by: Dr. Gary Gonzalez, MD, on January 2021.


The Life Extension Foundation regularly profiles and evaluates important new products on the market, often making them available directly to you, as well as to Foundation members at a discount via the Life Extension Buyers Club.


Green tea has taken the spotlight as a star nutrient. Studies suggest that green tea may prevent, and possibly treat, numerous diseases including cancer, arthritis, stroke and cardiovascular disease. It also appears to act as antioxidant, lower serum glucose, maintain kidney health and block angiogenesis. In fact, many doctors are now using high-doses of green tea as an adjuvant therapy in the treatment of cancer and other diseases, where the unique polyphenols that naturally occur in green tea are showing tremendous potential.

Fortunately, the marvels of the free market continue to yield economic and health dividends to those who have valiantly fought against FDA oppression. When Life Extension introduced green tea extract caps in 1992, the best the Foundation could offer was a 23% extract at a relatively high consumer price. As Federal judges continue to rule against the FDA in landmark court cases, the risks of being criminally prosecuted for producing dietary supplements has greatly diminished. The result has been an entrepreneurial avalanche of higher quality herb extracts coming to market at better prices.

Life Extension promised its members lower prices on better products if they battled FDA tyranny, and we are pleased to announce the availability of a new super-potent, 350 mg 95% green tea extract that costs the same as the previous 280 mg, 83% extract. This means that, with the new 95% green tea extract, you are getting 43% more green tea polyphenols for the same low price. Each one of these capsules is lightly caffeinated to reflect research findings that a synergistic protective effect when green tea polyphenols are combined with small amounts of caffeine.

Some people, however, cannot tolerate any caffeine, so Life Extension has always made a decaffeinated green tea extract available. The new, 300 mg decaffeinated 95% green tea extract is now available for the same low price as the previous 500 mg, 23% extract. This enables members to obtain 147% more green tea polyphenols, at the same low price.

Both of these new 95% green tea extracts are standardized to provide 35% of the epigallocatechin gallate (EGCG) polyphenol, the most potent cancer cell suppressing polyphenol found in green tea. Depending on how green tea is brewed, each one of these capsules equals four to ten cups of green tea in polyphenol content.
