The bioflavonoid Quercetin is found in grape skins, onions, apples, buckwheat, and other food sources, and it supports a wide variety of health aspects.  

It promotes both cardiovascular and endothelial health and may help maintain healthy blood pressure already within the normal range. (1-5)

Vitamin C also supports iron absorption (16,17). Furthermore, it participates in the formation of collagen that supports arterial walls, skin, bones, and teeth (11-13).  

Vitamin C also plays a role in protecting against environmental and physical stresses. (18)
