Drinking green tea better than taking supplements

Dietary pretreatment with the green tea polyphenol protects mice from liver toxicity caused by subsequent high oral doses of the same compound, the findings showed. "We believe this study indicates that those who are chronic green tea consumers would be less sensitive to potential liver toxicity from green-tea-based dietary supplements," Lambert noted.

He, however, added that the beneficial effects that people have reported as being associated with green tea are the result of dietary consumption rather than the use of supplements.
