What to Know About Flavonoids

Flavonoids (pronounced as fla-vuh-noydz), are naturally occurring bioactives (or plant compounds) found in tea. While flavonoids are found in many plant-based foods, like fruits and dark green veggies, tea is one of the top sources of flavonoids in the diet and can be a convenient way to help support a healthy heart with two cups every day.1,2,3,4,5
