Quercetin is a flavonoid, which is a type of plant pigment and phytonutrient. It is found in a variety of plant-based foods, such as fruits (apples, berries, grapes), vegetables (onions, broccoli, kale), and herbs (ginger, ginkgo biloba). Quercetin is known for its antioxidant and anti-inflammatory properties, which can help protect the body against damage caused by free radicals and reduce inflammation. It has also been studied for its potential benefits in supporting immune function, cardiovascular health, and overall wellness. Quercetin is available as a dietary supplement and is often used in combination with other antioxidants to enhance its effects.
