What Is Optimized Quercetin?

Quercetin is a bioflavonoid found in red grape skins, red onions, apples, buckwheat and other food sources. Quercetin supports healthy cellular function, cardiovascular health and has also been shown to encourage a healthy immune response, especially to seasonally changing environments.
