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.

Supports cardiovascular and endothelial health

Quercetin promotes cardiovascular health by protecting the integrity of your vascular endothelium.^1-4 One way quercetin does this is by encouraging healthy levels of nitric oxide: which supports healthy blood pressure levels already within the normal range.⁵

This unique phytonutrient also supports healthy cholesterol levels already within normal range.⁶ Quercetin also helps reduce oxidative stress, promotes a healthy inflammatory response in blood vessel walls as a result of healthy gene expression,⁷ and supports healthy blood glucose levels already within normal range.^8-14

Promotes a healthy immune response

In human cell culture studies, quercetin has been shown to block the manufacture and release of inflammation-causing substances,^15-18 which can help support a healthy immune response, especially to seasonally changing environments. And our Optimized Quercetin blend also contains vitamin C and camu-camu berry extract to further promote healthy immune function.
