  • Polyphenol antioxidants are termed as catechins and composed of the majority of green tea extract's antioxidant content. Among the catechins in green tea, EGCG or epigallocatechin gallate is the most researched and is known for providing the most health benefits.
  • Few pieces of study have shown that green tea extract helps in increasing the antioxidant capacity of the body and protects against oxidative stress m
  • Green tea boosts antioxidant capacity, which is useful in preventing various health problems caused by oxidative stress.

Promotes heart health

  • Oxidative stress increases the buildup of fat in the blood, which promotes inflammation in the arteries and leads to high blood pressure. The antioxidants present in green tea helps in decreasing inflammation and reduces blood pressure. They can also inhibit fat absorption in cells, and thus helps in reducing blood fat levels.
  • One study has shown that there has been a significant decrease in blood pressure as compared to the placebo group when taken 379 mg of green tea extract daily for 3 months. Also, a significant reduction in blood fat levels including triglycerides and LDL cholesterol has been found.
  • Since high blood pressure and high blood fat levels are the major risk factors for heart diseases, thus regulating them can promote heart health.

  • Green tea extract also helps in decreasing the action of heavy metals like iron and copper. These heavy metals can cause damage to brain cells.
  • It also helps in increasing memory by enhancing the connection between different parts of the brain.
  • Studies have shown that green tea extract improves task performance more compared to the placebo group.
