Key Points:

Nutrition experts identify green tea, including matcha, as the top tea for brain health due to its unique combination of bioactive compounds like catechins (especially EGCG), L-theanine, and caffeine, which support calm focus, mental clarity, and long-term cognitive health.
Long-term studies link regular green tea consumption with a lower risk of cognitive decline, highlighting its antioxidant and anti-inflammatory benefits that protect brain cells as people age.
Green tea differs from black tea by having minimally oxidized leaves, preserving higher levels of brain-supportive catechins, and containing less caffeine, making it a better option for sustained attention without overstimulation.
Experts recommend brewing green tea with hot (not boiling) water at 160–180°F
