What is Quercetin?

Quercetin is the best-known bioflavonoid (a water-soluble plant substance found in a number of vegetables and fruits) and an antioxidant. It belongs to plant pigments and gives a certain colour to vegetables and fruits. Quercetin is the most common in the human diet.

Quercetin, along with other flavonoids, has an antioxidant effect: it blocks free radicals and prevents various molecules from oxidating.
