Benefits at a Glance

Supports healthy seasonal immune response
Encourages healthy endothelial integrity
Supports already-healthy blood glucose levels
Promotes cholesterol levels already within normal range

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. One way quercetin does this is by encouraging healthy levels of nitric oxide: which supports healthy blood pressure levels already within the normal range.

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

Promotes a healthy immune response

In human cell culture studies, quercetin has been shown to block the manufacture and release of inflammation-causing substances, 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.
