Health Benefits Unlike regular green tea leaves, which are removed when brewed, Matcha leaves are whisked with water and consumed entirely. This ensures that Matcha drinkers consume a higher concentration of green tea antioxidants, vitamins, minerals and fibers. Matcha also contains high amounts of L-theanines – a unique set of natural amino acids found almost exclusively in green tea – as well as tea caffeine theophylline. Together, these substances are thought to help provide increased mental clarity and energy. Click here to view AIYA's Matcha Nutritional Analysis and ORAC Test Results.
