What Is Egcg From Green Tea

Egcg As An Antioxidant

Should you take Green Tea Extract (EGCG)?

EGCG is a potent antioxidant. An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation reactions can produce free radicals. The two most important oxygen-centered free radicals are superoxide and hydroxyl radical .

Although free radicals are formed naturally inside our bodies, they can cause reactions that end up damaging cells. In fact, high amounts of them may contribute to many diseases, the most important one being cancer.

Our organism has natural mechanisms to prevent or heal damage done by free radicals. One of them is by using vitamin C an E, which are also antioxidants. Whats great about EGCG is that it has an even higher antioxidant effect than those vitamins.

How To Get The Most Egcg And Polyphenols

Heres how to make the most of catechins, the antioxidant powerhouses of matcha tea.

  • Daily matcha is recommended for the greatest reward from these long-held properties.
  • Matcha is the finest source for some of natures key health compounds, many that are unlikely or impossible to find in regular diet.

Also, unlike brewed green tea, with matcha the whole leaf is also consumed as a fine powder, allowing these compounds an ample absorption.

May Offer Powerful Health Benefits

Test-tube, animal, and a few human studies indicate that EGCG provides numerous health benefits, including reduced inflammation, weight loss, and improved heart and brain health.

Ultimately, more research is needed to better understand how EGCG may be used as a preventative tool or treatment for disease, though current data is promising.

3.3.1.1 EFSA Comprehensive European Food Consumption Database

Since 2010, the EFSA Comprehensive European Food Consumption Database has been populated with national data on food consumption at a detailed level. Competent authorities in the European countries provide EFSA with data on the level of food consumption by their individual consumer from the most recent national dietary survey in their country . New consumption surveys added in the Comprehensive database were also taken into account in this assessment. The food consumption data gathered by EFSA were collected by different methodologies and thus direct country-to-country comparisons should be interpreted with caution. Depending on the food category and the level of detail used for exposure calculations, uncertainties could be introduced owing to possible subjects underreporting and/or misreporting of the consumption amounts. Nevertheless, the EFSA Comprehensive Database represents the best available source of food consumption data across Europe at present. Food consumption data from the following population groups: infants, toddlers, children, adolescents, adults and the elderly were used for the exposure assessment. For the present assessment, food consumption data were available from 33 different dietary surveys carried out in 19 European countries .

So, this means that green tea extract has a much higher dosage than recommended.

Thus, you may be wondering, is EGCG safe at high doses?

No, it isn’t.

At higher levels, you begin to approach EGCG toxicity.

If you continue to consume the extracts at such high levels, you could do significant damage to your liver.

Thus, to avoid green tea extract dangers, you need to carefully monitor your intake and never exceed the recommended dosage.

The Problem With Green Tea

It may seem fine to routinely consume a cup or two of green tea upon waking to get you going in the morning, but did you ever stop to think that the innocent cup of tea youre drinking may have a dark side to it?

Turn out it does.

The use of green tea extracts and infusions has been mildly associated with liver toxicity.

Research shows this is likely because of the catechin component of green tea, but namely EGCG.

Rodent studies indicate that exposure to EGCG has been shown to induce mitochondrial toxicity and generate reactive oxygen species , which are highly damaging to cellular DNA 9.

But wait, theres something else thats potentially more concerning

Many green teas are also contaminated with heavy metals, which accumulate in your body and can have potentially fatal outcomes when safe levels are exceeded 7.

Lead, cadmium, and nickel are the three heavy metals most commonly found in green teas.

  • Lead: found in the highest concentrations in green teas cultivated from South Korea and Japan , as well as China and India
  • Cadmium: found in the highest concentration in teas cultivated in China and India
  • Nickel: found in the highest concentration in green teas cultivated in South Korea and China

Heavy metal toxicity can cause decreased energy levels and damage the function of the brain, lungs, kidney, liver, blood, and other vital organs.

Long-term exposure can also lead to various physical, muscular, and neurological degenerative processes 10.

What Is Green Tea Extract Or Egcg

EGCG – Green Tea Extract Health Benefits

Green tea extract is a decaffeinated mixture of polyphenols from the Camellia sinensis tea plant .

In other words, green tea extract is a concentrated version of green tea without the caffeine content. As a dietary supplement, its available in capsule and powder form.

Most green tea extract comes from tea leaf scraps left over from tea processing. Commercial manufacturing techniques use hot water or solvents like alcohol or acetone for extraction followed by freeze-drying, spraying, or emulsification to ensure a predictable consistency.

In contrast to green tea extract, epigallocatechin gallate is a specific, individual catechin polyphenol found in Camellia sinensis. It also occurs in lower concentrations in many fruits, in nuts, and in cocoa.

Green tea contains around 7.3 grams of EGCG per 100 grams of dried tea leaves. Its the most abundant catechin in tea, accounting for nearly 60% of total catechin content in green tea.

Like green tea extract, EGCG is also available as a supplement and is made with a similar manufacturing process. EGCG used in supplements mainly comes from leftover green tea leaves, too.

Egcg In Green Tea And Matcha: Which Teas To Drink

A review examining catechin content in 18 different teas found the highest concentrations of EGCG in green tea. These results didnt come as a surprise, but interestingly, decaffeinated teas only had a fraction of EGCG compared to standard versions. It appears that the decaffeination process also removes catechins, so if you are trying to consume EGCG without caffeine, supplements would be the best choice.

Matcha is a powdered type of green tea commonly used in Japan. It is regarded as the finest-quality tea, and research has shown high concentrations of antioxidants and anti-inflammatory compounds of this beverage. In fact, one study found that concentrations of EGCG in matcha are at least three times higher compared to best quality green teas.

Studies show that EGCG consumption on an empty stomach increases absorption, which results in higher bioavailability. So, its best to drink your matcha or green tea before meals.

Are There Other Sources Of Egcg

If you are not a tea person and you are looking for good EGCG foods, you may be disappointed to find that teas are by far your best option. Small quantities of EGCG can be found in nuts and fruits like apples, avocados, pears, cherries, peaches, and berries. However, EGCG content in these foods is low, so consuming them wont get you the quantity needed for noticeable health benefits.

What Type Of Green Tea Has The Highest Amount Of Egcg

The catechin content of green tea depends on the processing method of the leaves before drying.

They undergo a certain degree of fermentation and heating prior to manufacturing, which can alter their inherent properties and thus, health benefits.

But other factors influence catechin levels like geographical location, growing conditions , and the type of green tea.

One research group suggests that a cup of green tea brewed using 2.5g of tea leaves with 200ml of water will contain around 90mg of EGCG 6.

Here are some teas containing the highest amounts of catechins 7:

  • Unfermented green tea
  • Japanese Sencha
  • Sri Lankan Green tea
  • Korean Jeoncha

According to one study, the total level of catechins and EGCG were green tea > green tea and oolong tea > black tea and pu-erh tea 8 old tea leaves contain less caffeine, but higher amounts of EGCG and total catechins than younger ones.

Egcg Warning: Efsa Safety Assessment Suggests Green Tea Supplements Should Come With Warning

The scientific opinion from the EU science agency provides a safety assessment of green tea catechins after concerns were passed on regarding possible harmful effects on the liver in Nordic countries.

In 2016, the Norwegian food safety authority Mattilsynet warned against green tea extract supplements following reports of liver damage. The authority pointed to high levels of the active substance EGCG in the products, which were far above that obtained from just drinking green tea.

Now EFSAs ANS Panel has provided a scientific opinion on the safety of green tea catechins from dietary sources, including preparations such as food supplements and infusions. In its report, the panel concludes that while intake of green tea catechins from green tea infusions are generally safe, there is potential for liver damage from supplementation with doses of EGCG above at 800 mg per day.
