Quercetin is a plant pigment responsible for vibrant colors in many plants. It acts as an antioxidant, which means it helps neutralize free radicals in the body. These free radicals can damage cells, accelerate aging, and contribute to chronic diseases.
Found abundantly in fruits, vegetables, and grains, this powerful compound offers a multitude of advantages for overall well-being. Consequently, many individuals turn to quercetin supplements to enhance their health routines.
