Tēgreen 97® is a proprietary, highly concentrated extract of the antioxidant catechins found naturally in green tea that promote long-term cellular health.


Green tea has been used traditionally in China for thousands of years for its health-preserving and revitalizing power. Modern science has identified powerful antioxidants in green tea called polyphenols. One group of polyphenols called catechins is particularly potent and highly effective at neutralizing free radicals at the cellular level. Catechins support healthy cell function while providing antioxidant protection to critical cell structures such as DNA. Demonstrated to cause a thermogenic effect, catechins also enhance the body’s metabolic rate.*

Tēgreen 97 from Pharmanex® is a proprietary, highly concentrated extract of the catechins found in green tea. As one of the most potent antioxidant supplements on the market, Tēgreen 97 has a 97% polyphenol content, 65% of which are catechins. Each Tēgreen 97 capsule contains the catechin equivalent of approximately seven cups of green tea and is 99.5% caffeine-free. Clinical studies show consuming 400 to 600 mg of catechins at one time will more effectively increase the level of catechins in the blood and increase the amount of time they stay in the body.*


  • Provides potent antioxidants to defend against free radicals at the cellular level*
  • Supports healthy cell function and helps protect cell structures, including DNA*
  • Thermogenic effect increases the body’s metabolic rate*

Has the antioxidant power of seven cups of tea per capsule and is 99.5% caffeine-free

The 6S Quality Process ensures the quality and potency of each Tēgreen 97 capsule
• Standardized for consistent and powerful benefits
• In a comparative study, Tēgreen 97 was shown to have better bioavailability and antioxidant capacity than drinking green or black tea*


Any adult concerned about long-term cell health and their antioxidant status should take Tēgreen 97. Individuals with a hectic, busy, or stressful lifestyle or those frequently exposed to pollution might also find benefits from Tēgreen 97 supplementation.


  • After water, tea is the most widely consumed beverage in the world
  • Tegreen 97 comes from green tea grown in Zhejiang, the number one tea-producing region in the world
  • Proprietary extraction of Tegreen 97 ensures a higher level of actives than most green tea products
  • The processing of black tea destroys some of the active components
  • Research shows that green tea is able to increase thermogenesis without caffeine
  • A study by UCLA compared the effects of plasma antioxidant activity after consuming Tēgreen 97, green tea, or black tea. Tēgreen 97 was shown to be more bioavailable than drinking green or black tea, and increased plasma antioxidant capacity more effectively


How does Tēgreen 97® work?

Increasing evidence suggests that the therapeutic effects of green tea are mediated by tea polyphenols. Tēgreen 97 provides triple-action cell protection by supporting the body in neutralizing three cell jeopardizing substances: free radicals, nitrosamines, and potentially harmful toxins.

Why is Tēgreen 97 unique?

Tēgreen 97 provides more concentrated levels of green tea polyphenols available in most food supplements. Greentea characteristics vary widely according to growing region, altitude, climate, and processing techniques. Pharmanex adheres to the time-honored tradition of using only the finest leaf buds and young leaves of tea plants cultivated in Zhejiang Province. This province is the number one tea-producing region in China, producing some of the highest quality tea in the world. Our proprietary process maximizes the concentration of the naturally occurring polyphenols, while virtually eliminating caffeine.

How does Tēgreen 97 promote thermogenesis?

Several studies indicate that the thermogenic effects of green tea are due to properties beyond caffeine content. One clinical study showed that green tea extract increased 24-hour energy expenditure (which relates to thermogenesis and metabolic rate) and fat oxidation in humans more than caffeine alone or placebo. In addition, the results of a study on Tegreen 97 were highlighted at the April 2003 FASEB meeting where the benefits of Tegreen 97 in improving lipid and glucose metabolism, maintaining normal insulin sensitivity, and balancing the metabolic rate of fat deposit and fat burning were discussed.*

Are there scientific studies validating this product?

Epidemiological, animal, and in vitro studies document the health maintenance and antioxidant benefits of green tea. Numerous studies using the proprietary extract found in Tēgreen 97 (known as Xin Nao Jian in Asia), suggest that the polyphenols in Tēgreen 97 provide a broad spectrum of antioxidant benefits.

Is Tēgreen 97 standardized?

Tēgreen 97 is an extract of green tea leaves, standardized to contain a minimum of 97% pure polyphenols, 65% of which are catechins (> 95 mg EGCg per capsule).

Is Tēgreen 97 decaffeinated?

Tegreen 97 is considered decaffeinated for labeling purposes. Tegreen 97 contains approximately 1.5 to 2 mg of caffeine per capsule, which is well below the stimulatory level. For comparison, a cup of coffee contains 100 to 150 mg of caffeine.

Is this product safe?

Tēgreen 97 is safe at recommended dosages. Do not exceed 1,200 mg of green tea in combination with other supplements that contain green tea.


As a dietary supplement, take one (1) to four (4) capsules daily; preferably one (1) to two (2) each morning and evening with food. Store in a cool, dry place.
