Essential Nutrients for a Naturally Healthy Body

  • Research suggests that antioxidants can be beneficial to health by helping the body protect itself from the harmful effects of "free radicals".
  • Studies provide evidence that tea contains protective antioxidants that can help body protect itself against free radicals, molecules that can damage cells.
  • Unsweetened, fresh tea is sodium-free, sugar-free, fat-free, virtually calorie-free and a satisfying, aromatic beverage. It's an ideal choice for a healthy lifestyle or weight-loss, especially when substituting for other sugar sweetened beverages.
  • In a study comparing tea and coffee showed that tea produced more consistent levels during the day and appeared to have a more gentle reviving effect. Green tea has about half the caffeine as a comparable cup of regular brewed coffee. Together with other research conducted on caffeine and sleep, these studies suggest that tea provides the potential beneficial effects of caffeine on performance during the day without disrupting sleep at night.

Frequently Asked Questions (FAQs)

Q. What does drinking tea do for my heath?
A. Find out in the Tea & Health section on this site.

Q. How much tea do I need to drink each day?
A. Studies show that one cup of green tea with about 30 to 60 milligrams of polyphenols isn't enough. To receive maximum benefits from tea, you should drink between four and ten cups of green tea, or get 120 to 600 milligrams of tea polyphenols, every day.

Q. What are free radicals?
A. Free radicals are unstable molecules such as hydrogen, nitric oxide (NO) and oxygen (O2). They occur naturally in the body and result from chemical reactions during normal cellular processes. They also result from exposure to pollution, sunlight, cigarette smoke, auto and industrial emissions and other toxins. Free radicals attack other molecules in the body and can damage cells resulting in the formation of another free radical and the process just continues. Free radical damage is a possible contributor to chronic and aging diseases including cancer, heart disease, stroke, rheumatoid arthritis, cataracts and Alzheimer's disease.

Q. What are antioxidants?
A. Antioxidants are substances that prevent or slow the breakdown of another substance by oxygen. They help prevent free radical formation inside the body, preventing or delaying cell and tissue damage caused by free radicals.

Q. Is green tea a good source of antioxidants?
A. Green tea has more antioxidant protection than either Vitamin C or E. In 1997, Lester A. Mitscher of the University of Kansas demonstrated that at least three of green tea's catechins outperform a number of other common natural antioxidants.

Q. Is green tea better than black tea?
A. For maximum health benefits it often is. Fresh green tea leaves contain the highest polyphenol amounts. All teas - black, green and oolong are from the same plant, Camellia sinensis, and contain polyphenols. It's the amount of processing each undergoes that determines the variety of tea and the eventual polyphenol content.

  • Black tea is allowed to dry slowly, essentially fermenting, which oxidizes the leaves and deactivates many of the polyphenols.
  • Oolong tea is dried (oxidized) some, but not completely, before being steamed to stop the oxidation process.
  • Green tea is steamed before it's dried, which deactivates the enzyme that causes oxidation and locks in a high polyphenol content-60 percent more than black tea.

Q. Does tea have caffeine?
A. Yes. Even decaffeinated tea has a very small amount of caffeine. Green tea has less caffeine than black or oolong tea. The amount of caffeine depends on how tea is brewed, how long it's brewed, and what part of the tea plant - the leaf/bud comes from and the size of the leaf when brewed. Tea bags usually have smaller leaves or pieces of leaves and result in more caffeine when brewed.

Q. Is unflavored tea healthier than flavored tea?
A. No. Flavorings simply add taste and/or sweetness to tea. They don't affect the underlying health benefits of the tea itself.

Q. Why are green tea extracts better than regular tea bags?
A. Extracts concentrate the beneficial compounds in tea, delivering more benefit per serving. One gram of dried green tea leaves contains up to 10 percent polyphenols. That gram of tea, placed in a tea bag, has polyphenols dissolution rate of 30 percent, which means that only 30 percent (less than one third) of the beneficial components fully dissolve and are available. The result: once brewed, a typical cup of green tea has just 30 to 60 milligrams of polyphenols. And 150 to 300 milligrams of polyphenols are needed for maximum health benefits, which means that a person needs to drink four to six cups of green tea every day. While people in China and other Pacific Rim countries regularly drink this much, most Americans don't or won't.

Q. What about liquids and capsules?
A. Capsules containing extracts have been the most popular dosage form for green tea polyphenols for some time. However, when solid dosage forms (capsules or tablets) are ingested, dissolution and absorption are low. And slower dissolution and absorption rates decrease the bioavailability of beneficial polyphenols and can irritate the digestive tract. Plus many extracts are just that, extracts. They contain individual components from tea, but not all components. Some researchers think that tea's benefits are the result of all components working together. Liquid dosage forms offer a much higher dissolution rate and a 400 percent faster absorption rate than solid dosage forms. One cup of TeaTech instant green tea has 300 milligrams of polyphenols as well as all of green tea's natural healthy nutrients. One serving offers the same benefits and amount of absorbed polyphenols as taking 1,200 milligrams of green tea capsules every day.

Q. What's the Difference between TeaTech Green Tea Extract and Others?
A. The advantages of TeaTech proprietary Green Tea Extracts are:

  • The only Green Tea Extract made from fresh (not dried) green tea leaves and using only water in the extraction process - to provide all the health benefits of green tea including polyphenols (antioxidant flavonoids), vitamins, amino acids, minerals, fibers and more.
  • Patented extraction process -100% natural, no chemicals, alcohol or organic solvents used in processing or manufacturing.
  • 300 mg of antioxidants (polyphenols) and 200 mg of EGCG per serving - equals 8 cups of most brewed green teas.
  • Great natural fresh tea taste and color - no artificial flavors, colors or preservatives.
  • 100% of the daily value of Vitamin C per serving.
  • 50% less caffeine than most coffees - only 15-40 mg per serving.
  • Great cold or hot, just add water.
