Staying Healthy  ▶ Supplement Facts  ▶

Mega Green Tea Extract (lightly caffeinated) provides powerful antioxidant effects throughout the body. Green tea contains health-promoting polyphenols including epigallocatechin-3-gallate (EGCG), a powerful antioxidant which has been the subject of extensive scientific research. So pour on the multiple health benefits with this essential extract!
Benefits at a Glance

  • Powerful antioxidant
  • Supports cell membrane integrity
  • Boosts liver detoxification
  • Enhances immune function
  • Supports healthy cholesterol levels already within normal range and lipid profiles
  • Supports healthy cell growth
  • Possibly promotes weight loss

Powerful Antioxidant Backed by Extensive Scientific Research
The antioxidant activity of EGCG is about 25–100 times that of vitamins C and E. One cup of green tea provides roughly 100 mg of polyphenols and has antioxidant effect greater than a serving of broccoli, spinach, carrots or strawberries.
More Polyphenols in One Capsule than Several Cups of Green Tea
One capsule of Life Extension’s Mega Green Tea Extract provides more polyphenols than you get from drinking seven cups of green tea. This green tea extract is standardized to 98% polyphenols and contains 326.25 mg of EGCG, by far the most important polyphenol that green tea provides. And green tea powdered extracts have been shown to absorb 60%–90% better into the bloodstream and to be far more bioavailable than drinking green tea itself.
Research Supported Benefits of Green Tea
The Chinese have used green tea for therapeutic purposes since 2000 BC. More recently, volumes of published scientific findings attest to its multiple health benefits … including:

  • Scavenging reactive oxygen species such as superoxide and the hydroxyl and peroxyl radical 
  • Cell membrane supporting properties
  • Possibly promoting weight loss
  • Boosting the effectiveness of enzymatic phase II detoxification
  • Helping maintain healthy cell proliferation
  • Helping maintain healthy blood cholesterol, LDL and triglyceride levels already within normal range
  • Enhancing immune function
  • Displaying protective effects on brain tissues

Mega Green Tea Extracthas been concentrated and dual standardized to ensure the highest quality, consistency and biological activity. This advanced extract contains 98% total polyphenols and 45% epigallocatechin-3-gallate (EGCG)



 Green Tea has been implicated in benefiting almost every organ system in the body. It appears cardioprotective, neuroprotective, anti-obesity, anti-carcinogenic, anti-diabetic, anti-artherogenic, liver protective and beneficial for blood vessel health. These beneficial effects are seen in doses present both in green tea itself (as a drink) as well as from a supplemental form.

About 30% of the leaves by weight are either favonols or flavanols, the latter of which is comprised mostly of compounds called catechins. These catechins are then broken down into four main classifications of: epigallocatechin-3-gallate (EGCG), epi-gallocatechin (EGC), epicatechin gallate (ECG) and epicatechin (EC). Although all catechins share similar properties, EGCG appears to be most potent in regards to many of them. These four catechins are the main catechins, although some other isomers or conjugates may be present.

We selected this product because it contains multiple polyphenols and not just the EGCG. While EGCG appears to be the primary active ingredient, it is always best when taking a supplement to get the product in combinations as close as possible to how nature designed it.

I also recommend people pay attention to the bioavailability issue. While studies can often show great results in vitro, it can be highly variable in people because 100% of the catechins may not get into the cell to work. This appears to be the case with green tea and thought should be given to increasing bioavailability. While the combination of all four catechins seems to be better than just isolated EGCG, taking green tea with fish oil or quercetin also appears to improve absorption.
