What are green tea benefits?
Antioxidants
This remarkable drink is rich in antioxidants, such as polyphenols and catechins (EGCG-epigallocatechin) that help protect the body from free radical damage and are the biggest secret of green tea.

Heart Health
Scientific research shows that consumption of green tea can reduce the risk of heart disease, heart attack and high blood pressure. May lower bad (LDL) cholesterol and increase good (HDL) cholesterol, reduce inflammation and improve blood vessel function thanks to catechins.
Catechins help protect blood vessels by reducing oxidation, inflammation and plaque formation in blood vessels. They also help maintain healthy blood fat levels and blood vessel flexibility. In addition, catechins directly affect cells in the body that are important for blood vessel health and reducing inflammation. Different types of catechins perform different jobs, such as scavenging harmful free radicals and regulating cholesterol. Newer research into exactly how catechins work may help develop new treatments for heart disease, he says, ScienceDirect.
Previous studies indicate a great help of green tea in reducing the risk of cardiovascular diseases, and new extended research yet to be implemented. Thus, numerous studies suggest that drinking tea can reduce bad cholesterol (total and LDL cholesterol) in normal and overweight people. However, no link was found between this tea and a reduction in triglycerides. To better understand the connection between regular tea drinking and blood fat levels, more large studies involving a larger number of people over a longer period of time should be conducted, according to National Center of Biotechnology Information.
Brain Functioning
This drink may have a positive effect on cognitive health. Studies have shown that it improves brain function and memory function, and reduces the risk of Alzheimer's and others neurodegenerative diseases because it contains caffeine, a natural stimulant that can improve functioning brain. It also contains L-theanine, an amino acid that has a calming effect.
This unique combination of caffeine and L-theanine can improve cognitive function without the effects of nervousness that we further associate with high caffeine intake from coffee.
The effective combination of caffeine and L-theanine has been proven through 20- such well-conducted research, in which it has been proven that it affects psychopathological symptoms (e.g. reduction of anxiety), cognition (e.g. benefits in memory and attention) and brain function (e.g. activation of working memory seen in functional MRI). It was also confirmed that the effects of this unique drink cannot be attributed to just one of its ingredients, but only to the combined effect of caffeine and L-theanine. It has also been established that the separate application of either of these two substances has a much smaller effect.
Coffee has a completely different, weaker effect on the brain and body because it does not contain L-theanine and therefore contrary to the way it works in green tea, caffeine has nothing to synergize with.
