This risk assessment of green tea catechins is carried out in the framework of the procedure under Article 8 of Regulation (EC) No 1925/2006. Article 8 is referring to a possible prohibition, restriction or Community scrutiny of a substance or ingredient due for example to the of harmful effects.
Since the implementation of this regulation, 5 mandates have been received by Efsa for safety assessment: 4 have been carried out (Yohimbine, Ephedra, hydroxyanthracenic derivatives, green tea catechins) and one is in the process of being published (monacolines of red rice yeast).
On March 14, 2018, with the report Scientific opinion on the safety of green tea catechins, EFSA confirmed that green tea catechins are generally safe for humans.
Catechins are antioxidants compounds, part of the flavonoids groups. They are associated with various health benefits but also possible harmful effects.The average daily intake of epigallocatechin gallate (EGCG), the most abundant catechin in green tea, derived from the consumption of green tea infusions is between 90 and 300 mg while the daily intake of EGCG due to the consumption of food supplements containing green tea catechins is between 5 and 1000 mg.
The experts panel tried to find a relationship between the consumption of EGCG and hepatotoxicity. The scientific team concluded that catechins, derived from the consumption of green tea infusions and reconstituted drinks with an equivalent composition to traditional green tea infusions, are not a risk for the human health and they also recommended, for health benefits, to do not overpass the daily intake of 800 mg of EGCG taken as food supplements.
