Why You Should Supplement With a Green Tea Extract

By Michael A. Smith, MD

You can find references to green tea in Chinese literature as far back as 5000 years ago. There’s an old Chinese legend that says a man was out walking one day when he accidently tasted the juices from the leaf of a tea plant. He thought it tasted great and suspected that the tea had special medicinal properties.

As with all of ancient history, there are many different stories to be told. Another legend suggests it was actually an Emperor called Shen Nung who discovered tea when a tea blossom fell into a cup of hot water that he was drinking.

Maybe these two men were even one in the same person, who knows? Fortunately, it doesn’t really matter. From that point forward, green tea became - and remains - an industry leader in terms of both benefit and popularity.

Why is Green Tea Beneficial?

Green tea contains plant-based antioxidants called polyphenols. One in particular is called EGCG (epigallocatechin-3-gallate), which has been the subject of extensive scientific research. The antioxidant activity of EGCG is superior to that of vitamins C and E.

One cup of green tea provides roughly 200 mg of polyphenols and has antioxidant effects that are greater than a serving of broccoli, spinach, carrots or strawberries. Green tea has been shown to provide many benefits including:

  • Reducing oxidative stress1
  • Maintaining healthy fluid balance in your tissues2
  • Supporting a healthy weight3
  • Optimizes liver detox pathways4
  • Maintains healthy cholesterol already within normal range5
  • Enhances immune function6
Now, we definitely want you to drink green tea. However, if you really want to reap the full benefits, taking a concentrated capsule that includes the important EGCG is probably your best bet.

About Life Extension's Green Tea Extract

One capsule of our Mega Green Tea Extract provides more polyphenols than you get from drinking three cups of green tea. This 98% green tea extract is standardized to provide high potency EGCG, by far the most important polyphenol green tea provides.

Also, green tea powdered extracts have been shown to absorb better into the bloodstream and to be far more bioavailable than even drinking green tea itself.7

Mega Green Tea Extract has been concentrated and standardized to ensure the highest quality, consistency and antioxidant activity. This advanced extract contains 98% total polyphenols and 45% EGCG.

Green Tea Science Comes Full-Circle

We love how scientific evidence totally vindicates that ancient Chinese man who believed his newly found elixir was loaded with health benefits. That was one smart guy, to say the least.

Our advice? Do your part to emulate him and drink as much green tea as possible. But let’s be honest, drinking more than 3 cups a day is probably a stretch. This is where supplements come in. Take a capsule along with a cup of your favorite green tea to reap ALL the benefits of this ancient drink for years to come.

What about the fluoride content of green tea? The tea plant are known to being able to store up to 400 ppm of fluoride from their environment and from the soil and it is generally stocked in the leaves. Long term ingestion of tea (4 cups or more per day) can lead to increased density of lower spine and in some cases, bone fluorosis, espescially if a person has a low renal function.

I don't understand your references, are they from previous LEF articles and if so, where have they gotten their information?

Life Extension said...

Anonymous #1, if fluoride concerns you, try our capsules. There's no fluoride in them. Here's the product page: www.lef.org/Vitamins-Supplements/Item00953/Mega-Green-Tea-Extract-lightly-caffeinated.html

Anonymous #2, we double checked the references and they are correct. Could you be more specific? Thanks.

If it is the actual plant that that stores fluoride, and your capsules are made from the plant, how could they not contain any fluoride?

Life Extension said...

Our extraction process eliminates fluoride from the product. We offer a certificate of analysis for the product which shows the chemical composition of each capsule. If you would like to view the document, please call our advisors at 1-800-226-2370. Thanks

Is this supplement safe for people with thyroid disorders? Any interaction with medication?

LifeExtension said...

Anonymous - There is some research showing that high doses of green tea extract may inhibit thyroid activity in rats, although we haven't seen any studies on humans regarding this issue. In regard to medications, it's always best to take supplements at least two hours apart to avoid any potential interactions. Hope this information helps!
