What Does Green Tea Extract Do

does green tea contain caffeine

Because it contains many of the same compounds from Camellia sinensis, some of the properties of green tea extract are similar to the health benefits of green tea.

As well discuss more below, green tea extract and green tea are not interchangeable. However, researchers often use extracts to ensure consistent results in clinical trials so they dont introduce additional variables like different varieties of tea or steeping methods.

Similar to green tea, the extract has potent antioxidant effects and can neutralize free radicals that would otherwise cause oxidative stress and damage to cells.

EGCG is the second most powerful antioxidant in tea . One gram of EGCG is 50% more potent as an antioxidant than a 100-gram serving of blueberries.

Lastly, green tea extract also has a reputation as a fat burner.

But the evidence for the weight loss efficacy of green tea extract supplements appears to be inconsistent: while some studies have observed positive effects, a systematic review and meta-analysis from 2013 found that, overall, the evidence is inconclusive.

Drinking green tea or taking green tea extract is worth a try if you have already made lifestyle changes and want extra fat burning, but you shouldnt count on it reducing your body weight especially if you arent eating a healthy diet and exercising regularly.

Can Green Tea Prevent Heart Disease

Some data suggests that green tea can reduce the risk of cardiovascular diseasea narrowing of the arteries that can lead to heart attack, chest pains, or stroke.

For example, in a study of more than 40,500 adults, researchers in Japan found that those who consumed five or more cups of green tea per day were 26 percent less likely to die of cardiovascular disease over an 11-year period than those who drank just one cup per day.

Similarly, a study of 76,979 people published in the Journal of Epidemiology and Community Health in 2011 found that women who drank one to six cups of green tea per day had a reduced risk of dying of cardiovascular disease compared with those who drank none.

How might green tea protect the heart? Experts say it may reduce high cholesterol levels and high blood pressure, which are important factors in cardiovascular disease.

But while this is a potential benefit, it’s not conclusive, and high doses of green tea can reduce the effectiveness of the drug nadolol, used to treat high blood pressure and heart problems, cautions NIH.

To reduce your risk of diseases such as cancer and heart disease , he says, you need to eat a healthy diet that includes plenty of fruit, vegetables, and whole grains. You should also exercise and avoid smoking.

Biological And Toxicological Data

Biological and toxicological data on green tea extracts and substances have previously been evaluated by ESCO and EMA . The present opinion briefly reports the major conclusions from these reports. Additional information has been identified from the literature. In the toxicity studies, the doses are generally given as green tea preparations, with a highly varying content of catechins. To enable comparison between studies, the Panel considered only the content of EGCG in the administered dose of green tea catechins. The rationale for this is that EGCG is the major catechin in green tea, is present in plasma in the unconjugated form and the most cytotoxic catechin, compared to EGC and ECG in primary rat hepatocytes and in some studies it is the only catechin for which content is quantified and reported.

3.4.1 Absorption, distribution, metabolism and excretion

The toxicokinetic studies of catechins from green tea in humans and in animals including in vitro data was reviewed in the Annex B of the ESCO advice on the EFSA guidance for the safety assessment of botanicals , focusing on Dried Green Tea Extracts. An extensive overview on the metabolism of green tea catechins has been presented by Feng . More recently, EMA presented an assessment report on Camellia sinensis Kuntze, non fermentatum folium. This report contained overviews of available pharmacokinetic data regarding the herbal substance, herbal preparation and relevant constituents thereof, in animals and humans.

Its fair to say that superior evidence exists for the health benefits and safety of drinking green tea compared to taking green tea extract.

In fact, drinking a cup of green tea or more each day is not only safe, but its also the best way to obtain the most health benefits from green tea.

Epidemiological studies from Asian countries where daily green tea intake is the norm suggest virtually no adverse events aside from the possibility of excessive caffeine intake, and a modestly reduced risk of various health problems.

And as we discussed in the previous section, toxicology evidence suggests tea is a safer way to obtain EGCG and other green tea antioxidants than green tea extract and allows you to get over double the daily dose of green tea catechins without harm.

The quality of the tea you select and the method you use to brew it also affect the safety, catechin levels, and health benefits.

Low-quality teas have a higher risk of contamination with heavy metals, pesticides, fungi, and mycotoxins.

Finally, one study found that mountain-grown teas from China, harvested in the spring and brewed for 5-10 minutes at 176 degrees Fahrenheit , had the highest overall antioxidant content.
