2 Main Benefits Of Drinking Green Tea

1. Could improve memory


Green tea has been shown in studies to aid memory, owing in part to its theanine component…


For example, a 2014 research of 12 healthy volunteers published in Psychopharmacology discovered that green tea extract increased individuals’ working memory—a sort of short-term memory useful for planning, understanding, reasoning, and problem-solving.


Patients were given either 27.5 mg green tea extract or a placebo in a milk-based drink. They subsequently completed activities while their brain activity was monitored by an MRI.



Those that ingested the green tea extract had increased brain connectivity (the ability of various parts of the brain to communicate with one another), as well as better working memory and task performance.


Because the study included such a small number of patients, the findings are less conclusive. More study is needed to determine how green tea affects memory.


2. Mental health may improve

There’s a scientific reason why drinking a hot cup of green tea may be so calming. Tea, like certain mushrooms, has an amino acid called theanine, which has been shown in studies to:


  • Stress relief

  • Relaxation should be encouraged

  • Caffeine can cause anxiety


FYI: According to a 2016 study published in Pharmacognosy Magazine, green tea contains the highest content of theanine compared to other forms of tea such as oolong, black, and white tea.

A 2020 study published in Plant Foods for Human Nutrition discovered that taking a daily dosage of 200 to 400 milligrams (mg) of theanine decreased stress and anxiety in persons exposed to stressful situations.


Another 2019 study, published in Nutrients, indicated that individuals who took 200 mg of theanine daily for four weeks had larger benefits in sadness, anxiety, and sleep compared to those who took a placebo.


While all of these studies emphasize theanine’s potential mental health advantages, the levels of theanine they utilized are significantly higher than what you’d get in a cup or two of green tea.
