A concentration of 2.5 μM EGCG and ECG enhanced health- and lifespan as well as stress resistance in Caenorhabditis elegans. Catechins hampered mitochondrial respiration in Caenorhabditis elegans after 6-12 hrs and the activity of complex I in isolated rodent mitochondria. The impaired mitochondrial respiration was accompanied by a transient drop in ATP production and a temporary increase in ROS levels in Caenorhabditis elegans. After 24 hrs, mitochondrial respiration and ATP levels got restored, and ROS levels even dropped below control conditions. The lifespan increases induced by EGCG and ECG were dependent on AAK-2/AMPK and SIR-2.1/SIRT1, as well as on PMK-1/p38 MAPK, SKN-1/NRF2, and DAF-16/FOXO. Long-term effects included significantly diminished fat content and enhanced SOD and CAT activities, required for the positive impact of catechins on lifespan.

Flavanols are a large group of flavonoids, which include catechin, epicatechin, epigallocatechin, epicatechin gallate and epigallocatechin gallate. They are found in teas, cocoa, fava beans, red wine, and many fruits, particularly in the skins of grapes, apples, and blueberries. Image credit: Marijana.
