Green tea has an established reputation for general health enhancement. Abundantly endowed with polyphenols, this major class of health enhancing plant phytochemicals delivers benefits in the antioxidant, anti-cancer, anti-inflammatory, and fat weight loss categories. But it is in this last category that the prospect of using green tea has garnered so much renewed interest. Green tea polyphenols comprise natural substances that offer weight management support, and at the same time, polyphenols bolster health support in pertinent long term categories. The overall effect of green tea is to support weight management in conjunction with sensible dietary modification and modest exercise. Green tea extract is safe and not expected to cause adverse side effects. However, because long-term studies have not been done with green tea extract, it is not recommended during pregnancy and nursing.
