What Is Quercetin?

Quercetin is a type of flavonoid antioxidant that’s found in plant foods, including leafy greens, tomatoes, berries and broccoli. (1) It’s technically considered a “plant pigment,” which is exactly why it’s found in deeply colored, nutrient-packed fruits and veggies.

Considered one of the most abundant antioxidants in the human diet, quercetin plays an important part in fighting free radical damage, the effects of aging and inflammation. While you can get plenty of quercetin from eating a healthy diet, some people also take quercetin supplements for their strong anti-inflammatory effects.

Research now shows us that inflammation is the root of most diseases, including heart disease, cancer, cognitive decline, some mental disorders and autoimmune disorders. The most well-researched effects of quercetin on fighting inflammation have been found in foods (especially fruits and veggies) that naturally supply flavonoids and other polyphenols, so we still have more to learn about the long-term effects of taking antioxidant supplements to lower inflammatory diseases. At this time, practitioners and patients report using quercetin to effectively fight conditions related to inflammation, including…
