Quercetin belongs to a family of plant pigments known as flavonoids. In plants, flavonoids carry out essential functions such as attracting pollinating insects, combating environmental stresses, and regulating cell growth.
Since the 1990s, there has been a growing interest in dietary flavonoids due to their disease-protective contributions to plant foods. Flavonoids in foods have exhibited anti-inflammatory, anti-clotting, antidiabetic, and nerve protective properties. Also, flavonoids have beneficial effects on cell-cell communication, which play a critical role in health.
Quercetin is found in everyday foods such as onions, apples, berries, teas, kale, broccoli, scallions, and other plant foods. This phytonutrient has potent antioxidant, anti-inflammatory, anti-allergy, immune balancing, and antiviral properties.
