Quercetin promotes cardiovascular health by protecting the integrity of your vascular endothelium.1-3 Quercetin does this is by encouraging healthy levels of nitric oxide, which supports healthy blood pressure levels already within the normal range.4
This phytonutrient also supports already healthy cholesterol levels. Quercetin also helps reduce oxidative stress, promotes a healthy immune response in blood vessel walls as a result of healthy gene expression and supports healthy blood glucose levels already within normal range.6-11
In human cell culture studies, quercetin has been shown to inhibit inflammatory factors to support whole body health, which can help support a healthy immune response, especially to seasonally changing environments.12-14
