EGCG Green Tea Extract: 2 Things to Look for When Buying EGCG Supplements

Green tea is rich in antioxidants called polyphenols. The primary polyphenols are catechins and Epigallocatechin Gallate (EGCG) is the most active and potent of all catechins.

EGCG is found in abundant in green tea. This antioxidant is more powerful than vitamins C and E and protects against or minimises free radical damage.

EGCG Green Tea Extract – Health Benefits

Research findings suggest the potential of EGCG green tea extract in reducing the risks of diseases such as cancer, athritis, diabetes and heart disease.

EGCG Green Tea Extract Supplements

There are numerous EGCG green tea extract supplements on the market with different potencies. When reading the product label, there are 2 things to look for:
1. EGCG concentration, and
2. caffeinated or decaffeinated

1. ECGC concentration

EGCG is the active ingredient in green tea extract supplements, so you should always check its concentration. If the label states polyphenol or catechin content only, you don’t know how much EGCG that you are getting.

Important: A high polyphenol or catechin content does not necessary mean a high ECGC content.

In fact, some companies may state high polyphenol or catechin content when the green tea extract supplements contain little EGCG.

2. Caffeinated or decaffeinated

Green tea does contain caffeine, but much lesser than that in coffee. If you are sensitive to caffeine, you should choose a decaffeinated ECGC green tea extract supplement.

Life Extension produces a high quality and concentrated green tea extract supplement known as Life Extension Mega Green Tea Extract. It is available in 2 versions: light caffeinated and decaffeinated. Each capsule contains 725 mg of standardized green tea extract that provides 98% polyphenols (710.5 mg) and 45% EGCG (326.25 mg). The high potency of Mega Green Tea Extract makes it easy for you to obtain the health benefits of green tea since you only need to take 1 capsule a day.

EGCG Benefits of Green Tea

Epigallocatechin gallate (EGCG) is a potent extract of green tea. Since green tea is not made from fermented tea leaves, it has high concentrations of EGCG. During fermentation, enzymes in tea leaves convert EGCG into thearubigin and theaflavin. This is why black tea has much lower EGCG content than green tea.

EGCG in green tea extract has received much attention for its therapeutic properties. There is increasing evidence to support EGCG health benefits. Most findings are based on population studies and research involving laboratory animals. EGCG benefits of green tea for humans should be evaluated in clinical trials.

Results from studies suggest that ECGC:

- lowers bad and increases good cholesterol
- may help prevent atherosclerosis and reduce the risk of heart disease
- may reduce the risk of cancer by inhibiting tumor growth
- may improve skin health
- may protect against cartilage damage and alleviate inflammation associated with osteoarthritis, rheumatoid arthritis, and bursitis.
- may help to treat inflammatory bowel disease (IBD)
- may prevent or help treat diabetes
- may aid weight loss

How to enjoy green tea EGCG benefits?

- If you are a tea drinker who isn’t currently drinking green tea, why not give it a try? You may just find yourself liking it.

- Another option is to take a high quality EGCG green tea extract supplement such as Teavigo or Mega Green Tea Extract, which you can find here: Green Tea Extract Capsules.  This is certainly more convenient and you don’t need to be downing cups of tea each day.

What are Green Tea EGCG, Polyphenols & Catechins?

EGCG, polyphenols and catehins are substances that contribute to the goodness of green tea. These terms are often used interchangeably and may be confusing for some people. We explain their differences below.

Polyphenol

Polyphenol is a type of antioxidant that can be found in plant foods such as tea, fruits, vegetables and cocoa. Antioxidants are known to combat free radicals and can prevent or minimise cell damage caused by the latter.

Catechin

Catechin is a type of polyphenol that is found in highest concentrations in green tea. Catechins in green tea consist of:
- epicatechin (EC),
- epigallocatechin (EGC),
- epicatechin gallate (ECG)
- epigallocatechin gallate (EGCG)

Epigallocatechin Gallate (EGCG)

EGCG is found in abundant in green tea and accounts for 10-50 percent of total catechins. Green tea EGCG is 25-100 times more powerful than vitamins C & E. The strong antioxidant effects of EGCG offer protection from and reduce free radical damage, to the body.

During production of green tea, tea leaves are lightly steamed to inactivate their enzymes and stop fermentation. This is why green tea is rich in EGCG as it is made from unfermented tea leaves.

Black tea has lower EGCG content. During fermentation, the enzymes in tea leaves convert EGCG into 2 complex polyphenols: thearubigins and theaflavins.

The concentration of ECGC in green tea infusion is determined by several factors such as brewing time, quality of tea leaves, water temperature and amount of tea leaves used.

How much green tea to drink?

There is no official recommendation on how much green tea one should drink. Studies into EGCG green tea health benefits have been based on 3-10 cups per day. An average intake of 3 cups of green tea per day would seem reasonable.

Remember, high quality green tea contains more EGCG than inferior green tea, so you don’t need to drink too much of it. If you do not like the taste of green tea or are generally not a tea drinker, taking an EGCG green tea extract supplement is another option.

One of the benefits of green tea is promoting healthy body weight. Animal and human studies have shown that green tea may aid weight loss or weight management by increasing thermogenesis, inhibiting fat digestion and absorption, increasing fat burning and enhancing exercise endurance.

If you want to lose weight with green tea but do not fancy drinking cups of the brew, green tea capsules are an easy and  convenient alternative. When buying green tea capsules for weight loss, make sure you check (more…)

Best Brands of Green Tea Extract Pills/Capsules

Drinking green tea is not to everyone’s liking. For those of you are always on the go, you may not even have time to make the brew.

No worries… you can still benefit from green tea’s potent antioxidant by taking green tea extract pills/capsules. A study published in The American Journal of Clinical Nutrition shows that absorption of polyphenols were enhanced when they were given as a green tea supplement in capsule form than as a tea beverage. There was also an increase in antioxidant effects from consumption of the green tea capsules.

Green Tea Extract Weight Loss: Does Green Tea Burn Fat?

Green tea extract and weight loss are being increasingly researched in animal and human studies. EGCG is the key component in green tea extract that has the potential to promote weight loss.

EGCG has been shown to aid weight loss by:
- increasing metabolism (thermogenesis)
- increasing fat oxidation/burning (green tea does burn fat!)
- reducing formation of fat
- reducing fat absorption
- improve insulin sensitivity

Here are some findings from studies on green tea extract weight loss

1. University of Birmingham 2008 study

Young healthy participants who ingested 3 capsules of green tea extract (total 366mg EGCG) experienced 17% higher average fat oxidation rate during moderate intensity exercise. Green tea ingestion also increased insulin sensitivity by 13%, which could potentially reduce the risk of type 2 diabetes mellitus.

2. Kao Corporation 2005 study

Daily consumption of green tea extract containing 690mg catechins for 12 weeks reduced body fat, waist circumferenece and subcutaneous fat area and BMI in 17 healthy Japanese men.
(source: http://www.ncbi.nlm.nih.gov/pubmed/15640470)

3. Kao Corporation 2007 study

240 subjects (Japanese men and women with visceral fat-type obesity) ingested green tea extract containing 583mg of catechins (catechin group) or 96mg of catechins (control group) per day for 12 weeks. The catechin group experienced greater reduction in body fat, blood pressure and bad cholesterol than the control group.
(source: http://www.ncbi.nlm.nih.gov/pubmed/17557985)

4. Unilever 2010 study

The consumption of 2 servings of high catechin green tea extract (886mg catechins, 104mg caffeine/day) for 90 days resulted in reduction of 5.6cm intra-abdominal fat area, 1.9cm waist circumference and 1.2kg body weight in 182 moderately overweight Chinese subjects.

Green Tea Extract Benefits

Green tea extract is derived from green tea leaves.

Catechins are the main ingredient in green tea extract. They are primarily epicatechin (EC), epigallocatechin (EGC), epicatechin gallate (ECG), and epigallocatechin gallate (EGCG). Numerous green tea extract benefits are attributed to these antioxidants, especially EGCG.

Scientific studies into green tea extract have uncovered its potential benefits to health. Green tea extract may:

- reduce the risk of heart disease
- lower cholesterol and triglycerides
- prevent cancer
- strengthen immune system
- aid weight management (see this post on Green Tea Extract Weight Loss)
- promote healthy teeth and gums
- reduce the risk of Parkinson’s disease
- lower blood pressure
- protect skin against UV damage

Green tea extract supplement is a viable option for those who don’t fancy drinking the brew. It is available with or without caffeine and is a convenient way to experience green tea extract benefits.

Low Green Tea ECGC Extract Increases Fat Oxidation by 33.3%

EGCG, the main catechin in green tea, have been extensively studied for its effect on weight loss or management.

According to a human study published in the the European Journal of Clinical Nutrition, low dose of EGCG was found to increase fat oxidation by 33.3%.

In the study on the effect of EGCG on fat oxidation in overweight/obese male volunteers, they took 4 supplements – low EGCG (300 mg), high EGCG (600 mg), caffeine (200 mg), EGCG/caffeine (300 mg/200 mg) or placebo – orally for 3 days.

Results:
The average increase in fat oxidation in the first 2 hours after meal was:

low EGCG (300mg) = 33.3%
high EGCG (600mg) = 20.2%
caffeine (200mg) = 34.5%
low EGCG and caffeine (300mg/200mg) = 49.4%

The increasGreen tea metabolism,prograde metabolisme in fat oxidation for low EGCG is similar to that of caffeine. However, when both (low EGCG and caffeine) are taken together, they increased fat oxidation by almost 50%!

Prograde Metabolism is a supplement that contains the same amount of EGCG and caffeine used in this study and other studies. It was created based on scientific evidence so that you consume the therapeutic levels needed to increase your fat oxidation and successfully lose weight and keep it off.
