What is Quercetin?
Quercetin is a natural flavonoid found in various plants and foods. This compound is known for its antioxidant properties, which help fight free radicals in the body. Quercetin may also have anti-inflammatory effects, promoting cardiovascular health. Many people seek out quercetin supplements to obtain these benefits, as it may not be present in sufficient quantities in the daily diet.
