From a scientific perspective, green tea extract capsules and drinking green tea do not have the exact same effect. While they both contain the same compounds, the bioavailability and absorption of these compounds differ between the two methods of consumption.

Green tea contains a variety of plant compounds called catechins, which are antioxidants. The most abundant and active catechin in green tea is epigallocatechin gallate (EGCG), which has been studied extensively for its potential health benefits. Green tea also contains small amounts of caffeine, which is known for its stimulating effects on the body.

When green tea is consumed as a beverage, the catechins and caffeine are dissolved in hot water, which helps to release the compounds from the tea leaves and make them more easily absorbed by the body. However, when green tea is consumed in capsule form, the effect is greater than that of drinking tea, because the content is the extracted essence of green tea, and the amplification of the effect is also more beneficial to the body.

Capsules typically contain dried green tea extract, which is made by extracting the catechins and caffeine from the tea leaves and drying them into a powder. This powder is then encapsulated and sold as a dietary supplement. Green tea extract is its concentrated form, such as a capsule containing the same amount of active ingredients as 4-6 cups of green tea. Usually, in order to amplify the benefits to the body, capsules are scientifically formulated with other ingredients. Take only one capsule to achieve multiple health benefits.

Green tea extract is also an important source of antioxidants. These are considered to have a range of health benefits, from promoting heart, liver, and brain health to improving skin and even reducing the risk of cancer.

1. High antioxidant

The health benefits of green tea extract are mainly attributed to its high antioxidant content.

Antioxidants can combat cell damage caused by free radicals, thereby helping to alleviate oxidative stress. This type of cell damage is related to aging and various diseases. Among the catechins in green tea, epigallocatechin gallate (EGCG) is the most studied and is considered to have the greatest health benefits. Research has shown that green tea extract can enhance the body's antioxidant capacity and prevent oxidative stress.

For example, a study asked 35 obese individuals to take 870 milligrams of green tea extract capsules within eight weeks. Their blood antioxidant capacity increased from an average of 1.2 to 2.5 μ Mol/L.

Green tea extract can enhance antioxidant capacity and help prevent various health problems caused by oxidative stress.

2. Promote heart health

Oxidative stress can increase the accumulation of fat in the blood, thereby promoting arterial inflammation and leading to hypertension.

Fortunately, the antioxidants in green tea extract can reduce inflammation and help lower blood pressure. They can also inhibit fat absorption in cells, helping to lower blood lipid levels.

A study asked 56 obese hypertensive individuals to take 379 milligrams of green tea extract capsules daily for three months. Compared with the placebo group, their blood pressure significantly decreased.

In addition, their blood lipid levels significantly decreased, including triglycerides, total cholesterol, and LDL cholesterol.

Another study conducted among 33 healthy individuals found that taking 250 milligrams of green tea extract daily for 8 weeks reduced total cholesterol by 3.9% and LDL cholesterol by 4.5%.

Given that hypertension and high blood lipid levels are risk factors for heart disease, regulating them can promote heart health.

3. Beneficial to the brain

The antioxidants in green tea extracts, especially EGCG, have been shown to protect brain cells from oxidative stress. This protection can help reduce brain damage that may lead to mental decline and brain diseases such as Parkinson's disease, Alzheimer's disease, and dementia.

In addition, green tea extract can reduce the effects of heavy metals such as iron and copper, both of which can damage brain cells. It has also been proven to help memory by enhancing connections between different parts of the brain.

A study asked 12 people to drink soda containing 27.5 grams of green tea extract or placebo. Then, while participants underwent memory tests, brain images were obtained to evaluate brain function.

Compared with the placebo group, the green tea extract group showed enhanced brain function and improved task performance.

4. Help to Lose weight

Green tea extract is rich in catechins and contains moderate amounts of caffeine. Catechin and caffeine have been shown to help weight loss by regulating hormones that enhance heat generation.

Heat generation is the process by which the human body burns calories to digest food and generate heat. Green tea has been proven to help your body burn calories more effectively, thereby reducing weight and promoting this process..

A study asked 14 people to take a capsule containing a mixture of caffeine, EGCG in green tea, and guarana extract before each meal. Then the impact of calorie burning was examined.

The study found that participants burned an average of over 179 calories over the next 24 hours.

Another study showed that after consuming green tea extract capsules containing 50 mg of caffeine and 90 mg of EGCG, 10 healthy men burned 4% of their calories within 24 hours.

In addition, a 12 week study of 115 overweight women taking 856 milligrams of green tea extract per day observed a weight loss of 2.4 pounds (1.1 kilograms) among participants.

5. Beneficial for liver function

The catechins in green tea extracts also help alleviate inflammation caused by certain liver diseases, such as non-alcoholic fatty liver disease (NAFLD).

A study provided 80 participants with NAFLD with 500 mg/day green tea extract capsules or placebo for 90 days.

The green tea extract group showed a significant decrease in liver enzyme levels, indicating an improvement in liver health.

Similarly, 17 NAFLD patients took 700 milliliters of green tea daily, which contained at least 1 gram of catechins, for 12 weeks. Their liver fat content, inflammation, and oxidative stress were significantly reduced.

It is important to adhere to the recommended dosage of green tea extract, as exceeding this dosage has been shown to be harmful to the liver.

Green tea extract comes in liquid, powder, and capsule forms. Liquid extracts can be diluted in water, while powders can be mixed into smoothies. However, its taste is very strong. Green tea extract capsules are more convenient and easy to take, with a recommended dosage of 250-500 mg per day. This amount can be obtained from 3 to 5 cups of green tea (approximately 1.2 liters).

The catechin most closely related to the health benefits of green tea extract is EGCG, so you need to ensure that the supplement you consume contains this substance.

Finally, it is best to take green tea extract with food. Exceeding the recommended dosage and taking it on an empty stomach may lead to liver damage.
