Both caffeine and l-theanine have synergistic effects meaning that they work together to increase brain function.
Moreover, studies show that green tea has the ability to reduce the risk of degenerative diseases such as Alzheimer’s disease and Parkinson’s disease this effect is thought to be due to the antioxidants and anti-inflammatory compounds present in green tea.
Green tea reduces the risk of several types of cancers
Cancer is caused by the uncontrolled growth of cells. It’s one of the world’s leading causes of death. One of the main factors that contribute to cancer is oxidative damage by free radicals. These free radicals are constantly being formed within our cells. However, cells also have the ability to neutralize these free radicals by producing antioxidants. Green tea is also a rich source of powerful antioxidants and anti-inflammatory agents. Research has shown that people who are drinking green tea are at a reduced risk for developing certain cancers including breast cancer prostate cancer and colorectal cancer.
