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
