Polyphenols (catechins) are the active ingredients in green tea providing a variety of benefits.

Green tea extract has been documented to lower blood pressure, reduce total cholesterol and LDL (the bad cholesterol), reduce serum amyloid-alpha (a marker of chronic inflammation) and reduce malondialdehyde (a marker of oxidative stress) (Nantz MP, et al. 2009). These are all cardiovascular risk factors and they were reduced in only 3 weeks.

Green tea may provide neutroprotection and has been associated with a lower prevalence of cognitive impairment (Kuriyama S, et al. 2006).

A study including 41,761 participants found that green tea consumptions were associated with a reduced risk of liver cancer (Ui A, et al. 2009).

Green tea polyphenols have been documented to reduce serum biomarkers in patients with prostate cancer (McLarty J, et al. 2009).

Regular drinking of green tea has been associated with a slight decreased risk of breast cancer (Shrubsole MJ, et al. 2008).

Green tea consumption was inversely associated with psychological distress in an assessment of 42,093 individuals (Hozawa A, et al. 2009). A consumption of 4 cups or more of green tea has been associated with a lower prevalence of depressive symptoms (Niu K, et al. 2009).
