The use of green tea extract is widespread in the world and delivers a concentrated dose of the beneficial nutrients and active ingredients of green tea.

What is Green Tea Extract?

Green tea extract is a different form of green tea, one that typically comes in a supplemental pill form, but provides many of the same great benefits as green tea as a beverage. However, green tea extract tends to be much more potent and is known as a fat-burning supplement. Packed with catechins, caffeine, and other volatile compounds, green tea extract is popular with bodybuilders and other active individuals who want an extra boost in their weight loss and metabolic goals.

As mentioned, green tea extract does contain caffeine, so it can have a number of side effects, but the extract is not inherently dangerous. Before adding green tea extract to your health regimen, you should speak with a doctor

Green Tea Extract Benefits

There are a number of proven benefits to green tea extract, including its impact on your heart health, obesity, and diabetes, among others.

Skin Quality

With an impressive concentration of catechins and polyphenolic compounds, this extract can help reduce free radical activity in the body and the skin, reducing the appearance of wrinkles, age spots, and blemishes.


Similarly, those antioxidants can help prevent chronic inflammation and oxidative stress in the body, thus lowering your chances of heart disease, and rheumatoid arthritis, among others.

May Help Prevent Cancer

Green tea extracts have been found to exert antiproliferative effects on prostate cancer cells because of the presence of polyphenols in it.

A 2018 research on cancer patients also suggests that the presence of ECGCs in green tea extracts has helped inhibit the proliferation and induce apoptosis in the lung, breast, and colorectal cancer.

The journal Oncotarget has recently published a study focussing on the anticancer effects of green tea extracts on prostate cancer progression. Although it couldn’t provide a clear insight as of now, the researchers see potential in using these extracts and are trying to research more.

Heart Health

There is a significant amount of research on the effects of green tea extract on heart health. It is known to lower cholesterol levels and reduce blood pressure, both of which can prevent heart attacks and strokes.

Weight Loss

Primarily used as a fat-loss stimulant, this extract can speed up the body’s metabolism and increase energy levels, making it a great workout supplement. It can help improve your passive fat-burning and make your workouts more efficient.

Brain Booster

Antioxidants in this tea extract are also linked to prevent neurodegenerative diseases by inhibiting the deposition of beta-amyloid plaque in neural pathways.


Green tea and its active ingredients are known to regulate insulin and glucose levels in the body, which helps diabetic patients live a more healthy and normal life.

Green Tea Extract Side Effects

While there are many obvious benefits to this supplement, there are some side effects which you should be aware of, such as potential liver damage and other caffeine-related symptoms.

Liver Damage

One of the active ingredients in green tea and a highly concentrated chemical in these green tea extract supplements is epigallocatechin gallate (ECGC). In moderate amounts, this antioxidant can work wonders, but in excess, it can speed up liver damage and compromise the health of your detoxifying organ.


There is a lot of caffeine in this extract, which can result in caffeine-related side effects, such as anxiety, nervous disorders, interrupted sleep patterns, and gastrointestinal distress. Pregnant and breastfeeding women should not take this supplement.
