Bioavailability has always been the achilles heel of polyphenols. Scientist felt they had a good handle on why these molecules exerted their health effects, but had a far less clear view of how to get them to the locations in the body where they could do the most good.

Tea polyphenols are poised to enjoy strong growth over the next decade, with a new market report calling for the global market in the ingredients to hit $368 million by 2020. That makes sense to observers, who say the popularity of tea, green tea in particular, boosts awareness of the ingredients derived from the plant.
