Green tea is one of, if not the most commonly used tea in the world. It has a ton of health benefits, which is why its extract is a popular supplement ingredient.
Green tea extract is popular for aiding weight loss. But that’s not all it does, as it also improves your skin, heart, liver, and brain condition.
1. Packed With Antioxidants
In case you didn’t already know, antioxidants are compounds that assist your body in fighting off harmful molecules called free radicals.
Even though moderate levels of free radicals are good for your health, in excess, they can lead to oxidative stress.
Oxidative stress has been directly linked to both acute and fatal health issues, including cancer, strokes, Alzheimer’s disease, and premature aging.
Green tea’s extract is packed with polyphenol antioxidants called catechins. Among them, the most beneficial catechin is epigallocatechin gallate (EGCG).
According to this study on 35 overweight people, taking 870 milligrams of green tea extract daily for 8 weeks can increase blood antioxidant capacity from 1.2 to 2.5 μmol/L.
2. May Improve Heart Health
Oxidative stress can cause high blood pressure, which can lead to several health problems.
Since green tea is packed with antioxidants, it can reduce inflammation and lower blood pressure. It can also reduce blood fat levels by slowing down the absorption of fat in cells. (1)
During this study on 56 overweight people, researchers find out that participants who were given 379 milligrams of green tea extract daily for three months noticed better blood pressure.
Additionally, the participants also experienced notable reductions in blood fat levels, including LDL cholesterol and lower triglycerides.
Furthermore, another study on 33 healthy people concluded that taking 250 milligrams of green tea extract daily for 8 weeks reduced LDL cholesterol by 4.5% and total cholesterol by 3.9%.
Therefore, since green tea extract can lower blood pressure and blood fat levels, it can improve your heart health.
3. Beneficial for Your Brain
Green tea’s antioxidants, especially EGCG, can protect brain cells from oxidative stress. (2)
Furthermore, green tea extract can reduce the effect of heavy metals like iron and copper — both of which can damage brain cells.
Moreover, it can also enhance memory by improving the connection between different parts of the brain.
Health Issues Associated With Green Tea Deficiency
People who drink green tea daily have lower chances of suffering from:
- High blood pressure
- Acute inflammation
- High cholesterol
- Oral leukoplakia
If you want to save yourself the discomfort caused by the health issues mentioned above, then you should add a selenium supplement to your diet.
Daily Recommended Intake
The daily recommended intake of green tea depends almost completely on the condition the user is trying to treat. According to recent research:
- For low blood pressure: 400 milliliters of green tea should be taken before lunch.
- For high blood pressure: 379 milligrams of green tea extract should be consumed daily for 3 months.
- For oral leukoplakia: 3 grams of mixed green tea should be taken orally and applied to your skin for 6 months.
