Introduction To The Common Use Of Gunpowder Tea
Gunpowder Tea is one of the most commonly used teas in the world.
Green tea extract is in its concentrated form, and only one capsule contains the same amount of active ingredients as a cup of regular green tea.
Like green tea, green tea extract is also an important source of antioxidants. These are believed 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).
Moreover, many studies have studied the ability of green tea extract to help lose weight. In fact, many weight-loss products list it as a key ingredient.
This article explores 10 science-based benefits of green tea extract.
- High antioxidant
The health benefits of green tea extract are mainly due to its high antioxidant content.
Antioxidants can fight against cell damage caused by free radicals, thereby helping to reduce oxidative stress. This cell damage is related to aging and many diseases (2Trusted Source).
Polyphenol antioxidants called catechins account for most of the antioxidant content of green tea extract. Among the catechins in green tea, epigallocatechin gallate (EGCG) is the most studied and is considered to have the greatest health benefits.
Studies have shown that green tea extract can enhance the body’s antioxidant capacity and resist oxidative stress (3Trusted Source, 4Trusted Source, 5Trusted Source).
For example, a study asked 35 obese people to take 870 mg of green tea extract in eight weeks. Their blood antioxidant capacity increased from 1.2μmol/L to 2.5μmol/L on average (5 trusted sources).
Green tea extract can enhance antioxidant capacity and help prevent various health problems caused by oxidative stress.
Green tea extract is rich in antioxidants called catechins, which have been shown to increase antioxidant capacity and prevent oxidative stress.
2. May promote heart health
Oxidative stress increases the accumulation of fat in the blood, thereby promoting arterial inflammation and leading to high blood pressure (6Trusted Source, 7Trusted Source).
Fortunately, the antioxidants in green tea extract can reduce inflammation and help lower blood pressure. They can also inhibit the absorption of fat in cells and help reduce blood lipid levels (7Trusted Source, 8Trusted Source, 9Trusted Source, 10Trusted Source).
A study asked 56 obese people with high blood pressure to take 379 mg of green tea extract daily for three months. Compared with the placebo group, their blood pressure was significantly lower (9Trusted Source).
In addition, their blood lipid levels were significantly reduced, including lower triglycerides as well as total and LDL cholesterol (9 trusted sources).
Another study conducted in 33 healthy people found that taking 250 mg of green tea extract daily for 8 weeks can reduce total cholesterol by 3.9% and LDL cholesterol by 4.5% (10 trusted sources) ).
Given that high blood pressure and high blood lipid levels are risk factors for heart disease, adjusting them can promote heart health.
The catechins in green tea may help lower blood pressure and improve blood lipid levels, thereby promoting heart health.
- Good for the brain
The antioxidants in green tea extracts, especially EGCG, have been shown to protect brain cells from oxidative stress (11Trusted Source).
This protection can help reduce brain damage (12 sources, 13 sources, 14 sources) that can lead to mental weakness and brain diseases such as Parkinson’s, Alzheimer’s 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 (15 sources, 16 sources).
It has also been shown to help memory by strengthening the connections between different parts of the brain.
In one study, 12 people drank soft drinks containing 27.5 grams of green tea extract or a placebo. Then, while the participants were taking a memory test, 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 (17Trusted Source).
China Green Tea extract has been shown to have a positive effect on brain health and memory, and may help prevent brain diseases.
