Quercetin is a bioflavonoid that supports cellular health, endothelial health, and healthy immune function. Optimized Quercetin delivers 250 mg of standardized quercetin in a bioavailable super food blend, as well as vitamin C and camu-camu berry extract to further support a healthy immune response and more.
Benefits at a Glance
- Promotes cellular health and DNA function
- 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.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.
