Matcha is a relatively new product from the perspective of western science. Therefore there is little research available on whether the claims made on behalf of Matcha are justified. However, as Matcha is really just a concentrated form of regular green tea, the research supporting the health benefits of green tea applies to Matcha green tea too. Whatsmore, it is likely that any of the benefits of regular green tea are much stronger for the concentrated Matcha green tea.
