Tea polyphenols are chemical compounds such as flavonoids and tannins found naturally in tea. Depending on how the tea is harvested, handled, processed, and brewed, the polyphenol level in the tea can vary. These chemical compounds are believed to be beneficial to human health, and they are the basis of many claims made about the health benefits of tea.
As with many natural compounds which appear to be beneficial to human health, it is difficult to isolate and study tea polyphenols on their own, and some researchers have suggested that their actions in the body may actually be the result of several compounds working together.
