Research shows Quercetin has a supportive role for immune, cellular and cardiometabolic health.

Immune Support:
Quercetin draws zinc into cells and therefore has antiviral activity against RNA viruses
Quercetin supports healthy mast cell function. An in vitro study performed on neutrophils reported that quercetin mediated beta-glucuronidase and lysozyme release, and significantly moderated arachidonic acid release from cell membranes.

Antioxidant Support:
Quercetin promotes cardiovascular health by protecting lipids from oxidation and supporting the health of capillaries by enhancing their strength and integrity. Studies suggest that quercetin may also promote healthy vision by mediating sorbitol production.

Cellular Support:
An animal study indicated that quercetin supported prostate cell health by moderating receptor function at the transcription level. Additionally, in vitro studies have reported that this powerful flavonoid may be supportive of colon and breast cell health.
