Quercetin is a plant pigment (flavonoid). It's found in many plants and foods, such as red wine, onions, green tea, apples, and berries.
Quercetin has antioxidant and anti-inflammatory effects that might help reduce swelling, kill cancer cells, control blood sugar, and help prevent heart disease.
Quercetin is most commonly used for conditions of the heart and blood vessels and to prevent cancer. It is also used for arthritis, bladder infections, and diabetes, but there is no strong scientific evidence to support most of these uses. There is also no good evidence to support using quercetin for COVID-19.
Fruits and vegetables offer the best sources of quercetin, Dr. Cederquist says.
“The highest concentrations of quercetin are thought to be in vegetables—especially those in the onion family and leafy greens—and fruits with edible skin like apples and grapes,” she says.
Foods that contain quercetin include:
- Citrus fruits
- Apples
- Grapes
- Onions
- Parsley
- Sage
- Sophora japonica.L
- Blueberries
- Blackberries
- Kale
- Broccoli
- Olive oil
- Tea
- Red wine

Why You Need Quercetin
Research shows that quercetin has many health benefits, including:
- Heart Health
Quercetin has been shown to support the cardiovascular system by lowering blood pressure and cholesterol and relaxing blood vessels. Because reduced blood flow can cause erectile dysfunction, flavonoids like quercetin can also improve men's sexual health.
- Brain Health
Improved circulation improves brain health as well. But quercetin can protect the brain in other ways, too. It may reduce inflammation and protect brain cells from toxins. Its antioxidant powers could lower the risk of Alzheimer's disease and other degenerative diseases of the brain.
- Anti-Cancer Effects
When free radicals damage cells in the body, those cells sometimes develop into cancer. Quercetin and other antioxidants reduce the risk of cancer by combating free radicals. A few studies have targeted quercetin particularly. In one, it slowed tumor growth. In another, it lowered the risk of lung cancer. The third was a lab study, which found that quercetin had the ability to attack leukemia cells.
