<p><a class="story-body__link-external" href="https://www.efsa.europa.eu/en/press/news/180418">A recent investigation by the European Food Safety Authority into the safety of green tea</a> concluded that catechins from green tea drinks are "generally safe", but when taken as supplements catechin doses at or above 800mg per day "may pose health concerns". The EFSA could not identify a safe dose on the basis of available data and called for more research to be carried out.</p>
