Green Tea and Oxygen Delivery

Epigallocatechin gallate reduces hypoxia-induced apoptosis

(Park HJ, Shin DH, Chung WJ, Leem K, Yoon SH, Hong MS, Chung JH, Bae JH, Hwang JS)

Epigallocatechin Gallate (EGCG) is the main polyphenolic found in green tea.  Research by Park et al, on the effect of EGCG on Hypoxia suggests that this Green tea compound could improve oxygen flow to tissues deprived of adequate supply.  Hypoxia happens when Oxygen supply is limited to tissue and  cells start to automatically die (Apoptosis).  This can happen at high altitude (Altitude sickness).

The research showed that Epigallocatechin gallate (EGCG) has an antioxidant effect and can protect hypoxia-induced damage.


Could GREEN TEA help climbers to survive at higher altitudes and further could GREEN TEA help sports people to tolerate higher levels of exercise stress and so improve their performance? We will keep you posted on this exciting area of medical research.
